Two thirds were randomized to active care(6 mo colonoscopy and drug intensification for endoscopic recurrence) and one third to drug therapy without early endoscopy. Colonoscopy at 18 mo and faecal calprotectin(FC) measurement were used to assess disease recurrence. Administrative data, chart review and patient questionnaires were collected prospectively over 18 mo.RESULTS: Sixty patients(active care n = 43, standardcare n = 17) were included from one health service. Median total health care cost was $6440 per patient. Active care cost $4824 more than standard care over 18 mo. Medication accounted for 78% of total cost, of which 90% was for adalimumab. Median health care cost was higher for those with endoscopic recurrence compared to those inremission [ $ 26347( IQR 25045-27485) vs $2729(IQR 1182-5215), P < 0.001]. FC to select patients for colonoscopy could reduce cost by $1010 per patient over 18 mo. Active care was associated with 18% decreased endoscopic recurrence, costing $861 for each recurrence prevented. CONCLUSION: Post-operative management strategies are associated with high cost, primarily medication related. Calprotectin use reduces costs. The long term cost-benefit of these strategies remains to be evaluated.展开更多

A meta-analysis with a random-effects model was used to calculate pooled odds ratios(OR) and confidence intervals(CI) for each outcome measure of interest. RESULTS: A total of 14 studies were included for metaanalysis, comprising a total of 5425 patients with CD 1024(biological treatment, 4401 control group). After biological therapy there was an increased risk of total infectious complications(OR = 1.52; 95%CI: 1.14-2.03, 8 studies) and wound infection(OR = 1.73; 95%CI: 1.12-2.67; P = 0.01, 7 studies). There was no increased risk for other complications including anastomotic leak(OR = 1.19; 95%CI: 0.82-1.71; P = 0.26), abdominal sepsis(OR = 1.22; 95%CI: 0.87-1.72; P = 0.25) and re-operation(OR = 1.12; 95%CI: 0.81-1.54; P = 0.46) in patients receiving biological therapy. CONCLUSION: Pre-operative use of anti-TNF-α therapy may increase risk of post-operative infectious complications after surgery for CD and in particular wound related infections.展开更多

The aim of this study was to determine the occurrence of common early post-operative complications after oral and maxillofacial surgery in relationship to the underlying systemic condition. A descriptive postoperative study was done whereby patients who underwent oral and maxillofacial surgery were included. The included patients were those who underwent surgery for different pathological conditions, trauma, developmental/congenital conditions and inflammatory conditions to mention few. Demographic data, complications developed within one week post operative, and underlying systemic comorbidities before and after surgery were documented and analysed. A total of 102 patients were included in the study. The mean age of participants was 30.00 ± 17.01 years with a range of 2 to 81 years. Majority 43.1% (n = 44) had benign tumors with a leading diagnosis of ameloblastoma. In general, the most common complications which were noted in the cases included Pain 98% (n = 100) and Post-operative Swelling 97.1% (n = 99). The presence of underlying systemic comorbid conditions has a significant role in occurrence of some severe complications. The occurrence of complications does increase the duration of stay in the hospital hence increasing cost of treatment for which bearers are both patients and the hospital.展开更多

This study assessed the current AMR patterns of bacterial isolates in post-operative wound infections in a tertiary care hospital in Kathmandu,Nepal. Pus swabs collected from post-operative wound infections and submitted for culture and sensitivity were included in this study. Isolation and identification of the organism was done by standard microbiological methods. Antibiotic susceptibility test was performed by Kirby Bauer disc diffusion method and result was interpreted as per National Committee for Clinical Laboratory Standards (NCCLS) guide lines. Of the 120 pus swabs processed for culture, 96 showed bacterial growth. Staphylococcus aureus 36 (37.5%) was the predominant gram positive isolate and Escherichia coli 24 (25%) was the major gram negative isolate .The infection was most prevalent in the age group 20-40 years. All S. aureus isolates were sensitive to aminoglycosides and vancomycin. Out of 36 S. aureus, 15 (41.66%) isolates were methicillin resistant S. aureus (MRSA). Staphylococcus epidermidis showed high resistance (50%-100%) to all antibiotics but were sensitive to vancomycin. All gram negative isolates showed high resistance against cephalexin (75%-100%) and ceftriaxone (25%-100%). Overall multi-drug resistant isolates were 66.7%. A high level of AMR was observed in gram negative bacterial isolates. Rational use of antibiotics and a regular monitoring of AMR patterns in post-operative wound infections are essential and mandatory to avert further emergence and spread of anti-microbial resistance among bacterial pathogens.展开更多

Laparoscopy is not well vulgarised in our settings. Objective: The main objective was to compare the surgical and post-operative outcomes of laparoscopic versus abdominal myomectomy. Methods: We performed a comparative analytical cross sectional study from 1st January 2016 to 31st March 2018 consisted of two groups: group 1 of women who underwent laparoscopic myomectomy (LM) and group 2 of women who underwent abdominal myomectomy (AM). The data collected was entered in Epi Info 7.2 version and exported to IBM SPSS Statistics version 22 for analysis. We used alpha error margin of 5% and confidence interval of 95%. Results: We enrolled 50 cases of myomectomy consisted of 33 (66.0%) files for AM and 17 (34.0%) files for LM. The clinical presentation of fibroid was similar in both groups. The main operation time (H) was (1.27 ± 0.13) for laparoscopy which is much less than (2.05 ± 0.07) for laparotomy group (p = 0.006). In AM group we had 04 post-operatory complications against zero complications in LM group but the difference was not statistically significant (p = 0.387). In the second look laparoscopy, the types of adhesions were not statistically significant (p = 0.471). Conclusion: Laparoscopic offers advantages compared to abdominal myomectomy.展开更多

Objectives: The purpose of the present study was to see the post-operative mortality after ileal perforation. Methodology: This prospective cohort study was conducted in the Department of Surgery at Dhaka Medical College Hospital, Dhaka, Bangladesh from September 2000 to December 2002 for period of 2 years and 3 months. All the patients presented with ileal perforation at any age with both sexes were included in this study. Patients were selected consecutively and the patients who showed ileal perforation at laparotomy were included in this study. Preoperative diagnosis was based on detailed history, complete physical examinations supported by plain x-ray abdomen in erect posture including both domes of diaphragm. After immediate resuscitation surgical treatment was undertaken as soon as possible following admission in all cases. The patients were followed up and the mortality profiles were recorded after surgical intervention. Result: Out of 53 patients having postoperative complications 38 patients were survived and 15 patients were expired. So total survivors were 85% and non-survivors 15%. In this study most of the mortality (12%) was attributed to septicemia and mode of death was multiple organ failure. Respiratory complications caused 2% mortality one patient died of ARDS and another elderly patient with preexisting bronchial asthma developed respiratory failure and was unresponsive to treatment. One death was related to faecal fistula followed by severe fluid, electrolyte and acid-base imbalance with peritonitis and gross sepsis. Conclusion: In conclusion, the mortality is significantly high due to septicemia, ARDS and faecal fistula.展开更多

Proper choice of Anesthetic technique, use of combined anesthesia and pre-emptive analgesia may prevent and decrease the incidence of chronic post-operative pain. Transverse abdominis plane block (TAP Block) is a regional anesthesia technique following abdominal surgeries which involve injection of a large amount of local anesthetics in TAP, an anatomical space between the internal oblique and transverse abdominis muscle. The aim of this review is to show the effect and uses of TAP block as a combined anesthesia and multimodal analgesia in preventing chronic post-operative pain.展开更多

Objective: To determine the post-operative outcome of the patients admitted in resuscitation. Patient and method: It was about a retrospective and transverse survey from June 2017 to May 2018 in the service of polyvalent resuscitation of the academic hospital center of Gabriel Touré. Have been included the patients operated for surgical or obstetric gynecology—pathologies admitted in resuscitation for post-operative complications established or potential precocious or late. The used statistical test was the Chi2 with p Results: During the period, 514 patients have been admitted in resuscitation of which 140 cases of post-operatively represented 27.2% of the admissions. Under hospitalization 35.7% of patients have presented a complication. The middle age of patients was 37.72 ± 20.9 years. The sex ratio was 0.70. The middle length of interventions was 122 ± 83 min with extremes going from 20 to 434 min. The predominant admission motive was hemodynamic instability. The delay of appearance intervening of the complications was 3 days in 94%. The predominant complications were: respiratory (32%), infectious (28%) and Cardiovascular (20%). The middle length of hospitalization was of 3.36 ± 2.90 days. The death rate was 15%. The complications were related age, the class of Alteme?er, the ASA, and the perioperative undesirable events with p Conclusion: The post-operative admissions in resuscitation are frequent including several factors of morbi-mortality. A better management per and postoperative of the patients operated would reduce the death rate. The profile mark is the one of a patient admitted for hemodynamic instability.展开更多

The patient’s visual acuity was no light perception (NLP) in the right eye and hand motion (HM) at 1’ in the left eye. Both pupils were unreactive and no relative afferent pupillary defect was noted. Anterior segment and fundus examination were unremarkable. T1 and T2 weighted MRI imaging of the brain was normal but diffusion weighted imaging (DWI) revealed areas of bright signal within both intraorbital optic nerves, confirming the diagnosis of posterior ischemic optic neuropathy.展开更多

Current practice dictates implantation of permanent pacemaker (PPM) when post-op CAVB persists >9 days. We propose that earlier PPM implantation may be the most cost-effective methodology since patient costs increase with extended length of stay (LOS). Methods: Data on the probabilities of persistent post-op CAVB were extracted from published reports. No individual patient data were utilized during this study. This was utilized to create a decision-making model and a total cost analysis on post-op day 0 - 10 to determine the most cost-efficient day to implant a PPM. Cost variables included estimates of daily cardiac ICU care, cost of PPM implantation, LOS, cost related to possible superficial or deep infection based on published prevalence rates (2.3% and 4.9%, respectively) and need for explant due to deep infection or recovery of native conduction. The model assumes 5-day minimum LOS and 1 day increase in LOS with PPM implantation. Cost data were obtained from relevant billing codes and manufacturer list prices for PPM and leads. A secondary analysis evaluated probability of unnecessary PPMs implanted and excess costs. Results: Post-op day (POD) 4 is the lowest total cost of PPM implantation for post-op CAVB, even when accounting for possible risk of either superficial or deep infection. A one-way sensitivity analysis accounting for variability of cardiac ICU care costs between centers ranging from $3000 - $9000 per day consistently replicates POD 4 as the most cost-effective day for PPM implantation. Implant on POD 4 results in a 26% chance of unnecessary implantation. Conclusions: The most cost-efficient day for PPM implantation for post-op CAVB is post-op day 4, which results in a minimum total cost savings of $17,422 per patient. Added costs due to risk of superficial or deep infection are marginal due to low prevalence of post-operative infection in this population.展开更多

There ...Background: Postoperative wound healing has been a problem which causes high mortality in the developing world;postoperative wound has been reported to cause devastating consequences and a measurable mortality. There is a limited number of published studies in Tanzania investigating Nursing practice on post-operative wound care in surgical wards at Muhimbili National Hospital, Dar-es-Salaam, Tanzania. This study assesses nursing practice on postoperative wound care by nurses in surgical wards at Muhimbili National Hospital. Methods: A cross-sectional study of surgical nurses was carried out through the use of randomly selected surgical wards at Muhimbili National Hospital in Tanzania from September 2011 to July 2013. A multistage cluster sampling technique was used to obtain a suitable number of study participants. Data collection was done using a checklist from a convenient sample of 71 nurses in selected surgical wards. Results: The result indicates that a big number of the participants were female (76.5%) and those of the age group 25 to 34 years were 40.8%. Participants exceeding a half of the selected sample reported to have poor post-operative wound care practice (57.7%). In comparison, male participants scored higher, and had better practice than their female counterparts, however, there was no considerable difference in the scores (P = 0.803). During set-up and preparation phase, the washing of hands before starting and after the completion of procedure was taken into consideration by less than half of the participants (49.3%). All participants did not ensure the environment is clean and take into account the patient’s privacy through the use of screen or even closing the room. The report shows that nurses take into consideration putting on clean gloves during the removal of the old dressing (99%), the use of sterile gloves during wound dressing was taken into consideration by most of the nurses (63%). Good practice was noted in applying dressing solution as recommended (85%), dry sterile dressing was applied by (90%), arrangement and setting up of dressing forceps and other items that may be needed in order of their application using forceps (20%), usage of forceps to dip gauze into antiseptic solution (35%) and cleaning of the wound cleaning from least contaminated to most contaminated area was only adhered to by (34%). Post-operative counseling and giving to the patient not to temper with the wound was done by a representation of only 15% of nurses. All the nurses did not do the documentation of the changes observed on the wound nor did they report on the patients comfort and the date and time after the procedure wound changes, reported patient comfort, and recorded date or time after the procedure. Conclusion: Majority of the nurses in surgical wards do not follow the postoperative wound care checklist provided by MNH although they know its importance. Assessment of the wound and documentation continues to be a problem in the nursing profession in Tanzania. Nurses are reasonably knowledgeable about the principal of wound dressing;however, lack of knowledge on some of the key principles of wound dressing is worth noting. Almost half of the nurses do not wash hands before and after the procedures, they don’t use single gauze in one direction only, not cleaning from least contaminated to most contaminated area, which can lead to wound contamination.展开更多

Volatile anesthetics impact neuronal tissue independent of effects attributed to the physical trauma of the surgery itself. While it is recognized that all aspects related to surgery may contribute to cognitive loss in some manner, the present paper focuses on the role of volatile anesthetics in promoting POCD. There is an increased risk of onset and progression of Alzheimer’s disease (AD) from POCD, implying that the neuropathogenesis between the two is similar. Human studies, being ethically limited in scope, require animal models as a substitute. While the literature using rodent models contains valuable information, we believe that the accessible and practical zebrafish will greatly enhance our further understanding of the molecular mechanism of POCD as it relates to AD. Disease genes and fundamental neurobehaviors of these teleost fish mirror those of mammals and humans, validating their use as a core research model for AD. Since the gradual senescence seen in zebrafish also resembles that found in humans, we numerically correlated the two lifespans, offering researchers a computational tool. Zebrafish, being aquatic animals, necessitates the use of miscible compounds, such as trifluoroethanol, whose anesthetic potency we are presenting. We also review the rodent and zebrafish literature relevant to POCD. Continued research with the leading-edge zebrafish unlocks the possibility that, in the future, perioperative intervention will prevent POCD.展开更多

In this context, we seek to evaluate the effectiveness of metoprolol compared to clonidine in the post-<span>operative control of systolic (SBP) and diastolic (DBP) blood pressures, and </span><span>heart rate (HR), when these medications are used in the immediate </span><span>pre-operative period. Method: this is a randomized double-blind clinical trial. Patients over 18 years old, according to the American Society of Anesthesiologists Physical Status Classification (ASA) I or II, who would undergo OLHN surgery, presenting with greater than 140 mmHg (SBP) or 90 mmHg (DBP), upon arrival at the surgical ward, were included in the study. 46 patients were randomized into two groups (C or M) who received clonidine (75 or 150 mcg) or metoprolol (5 or 10 mg), respectively. The averages of SBP, DBP and HR were compared between groups upon arrival at the post anesthesia care unit (PACU) and four hours post-surgery. Results: In group C, SBP (127.7 </span><span>±</span><span> 18.8 vs 137.3 </span><span>±</span><span> 14.1 mmHg, p = 0.03) and DBP (73.1 </span><span>±</span><span> 15.46 vs 82.6 </span><span>±</span><span> 7.9 mmHg, p <</span><span> </span><span>0.01) were lower, when compared with group M. No difference was observed in HR immediately upon PACU arrival. In addition, for four hours post-surgery, no change was noted in the SBP, DBP or HR. Conclusion: metoprolol was less effective than clonidine in reducing systolic and diastolic blood pressures in the immediate post-operative period of OLHN surgeries.</span>展开更多
文摘BACKGROUND Tourniquets are commonly used in elective extremity orthopaedic surgery to reduce blood loss,improve visualization in the surgical field,and to potentially reduce surgical time.There is a lack of consensus in existing guidelines regarding the optimal tourniquet pressure,placement site,and duration of use.There is a paucity of data on the relationship between the site of a tourniquet and postoperative pain in foot and ankle surgery.AIM To explore the relationship between tourniquet site and intensity of post-operative pain scores in patients undergoing elective foot and ankle surgery.METHODS Retrospective analysis of prospectively collected data on 201 patients who underwent foot and ankle surgery in a single institution was undertaken.Intraoperative tourniquet duration,tourniquet pressure and site,and postoperative pain scores using Visual Analogue Score were collected in immediate recovery,at six hours and at 24 h post-op.Scatter plots were used to analyse the data and to assess for the statistical correlation between tourniquet pressure,duration,site,and pain scores using Pearson correlation coefficient.RESULTS All patients who underwent foot and ankle surgery had tourniquet pressure of 250 mmHg for ankle tourniquet and 300 mmHg for thigh.There was no correlation between the site of the tourniquet and pain scores in recovery,at six hours and after 24 h.There was a weak correlation between tourniquet time and Visual Analogue Score immediately post-op(r=0.14,P=0.04)but not at six or 24 h post-operatively.CONCLUSION This study shows that there was no statistically significant correlation between tourniquet pressure,site and postop pain in patients undergoing foot and ankle surgery.The choice of using a tourniquet is based on the surgeon's preference,with the goal of minimizing the duration of its application at the operative site.

文摘Objective Type A acute aortic dissection(TAAAD)is a dangerous and complicated condition with a high death rate before hospital treatment.Patients who are fortunate to receive prompt surgical treatment still face high in-hospital mortality.A series of post-operative complications further affects the prognosis.Post-operative pneumonia(POP)also leads to great morbidity and mortality.This study aimed to identify the prevalence as well as the risk factors for POP in TAAAD patients and offer references for clinical decisions to further improve the prognosis of patients who survived the surgical procedure.Methods The study enrolled 89 TAAAD patients who underwent surgical treatment in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan,Hubei province,China from December 2020 to July 2021 and analyzed the perioperative data and outcomes of these patients.Logistic regression analyses were used to identify the risk factors for POP.Results In the study,31.5%of patients developed POP.Patients with POP had higher proportions of severe oxygenation damage,pneumothorax,reintubation,tracheotomy,renal replacement therapy,arrhythmia,gastrointestinal bleeding,and longer duration of mechanical ventilation,fever,ICU stay,and length of stay(all with P<0.05).The in-hospital mortality was 2.3%.Smoking,preoperative white blood cells,and intraoperative transfusion were the independent risk factors for POP in TAAAD.Conclusion Patients who underwent TAAAD surgery suffered poorer outcomes when they developed POP.Furthermore,patients with risk factors should be treated with caution.
文摘Objective Post-operative cognitive dysfunction(POCD)and post-operative delirium(POD)are two common post-operative cerebral complications.The current meta-analysis was to systematically review the effects of penehyclidine hydrochloride(PHC)on POCD and POD in surgical patients.Methods Electronic databases were searched to identify all randomized controlled trials comparing PHC with atropine/scopolamine/placebo on POCD and POD in surgical patients.Primary outcomes of interest included the incidences of POCD and POD;the secondary outcomes of interest included peri-operative minimental state examination(MMSE)scores.Two authors independently extracted peri-operative data,including patients'baseline characteristics,surgical variables,and outcome data.For dichotomous data(POCD and POD occurrence),treatment effects were calculated as odds ratio(OR)and 95%confidential interval(Cl).Each outcome was tested for heterogeneity,and randomized-effects or fixed-effects model was used in the presence or absence of significant heterogeneity.For continuous variables(MMSE scores),treatment effects were calculated as weighted mean difference(WMD)and 95%CI.Statistical significance was defined as P<0.05.Results Our search yielded 33 studies including 4017 patients.Meta-analysis showed that,the incidence of POCD in PHC group was comparable to that in saline group(OR=0.97;95%Ck 0.S8-1.64;P=0.92),scopolamine group(OR=0.78;95%CI:0.48-1.27;P=0.32)and atropine group(0R=1.20;95%Ch 0.86-1.67;P=0.29).The incidence of POD in PHC group was comparable to that in saline group(OR=1.53;95%CI:0.81-2.90;P=0.19)and scopolamine group(OR=0.53;95%CI:0.06-4.56;P=0.56),but higher than that in atropine group(OR=4.49;95%CI:1.34-15.01;P=0.01).Conclusions PHC premedication was not associated with increased incidences of POCD or POD as compared to either scopolamine or placebo.
文摘AIM: To define the cost-effectiveness of strategies, including endoscopy and immunosuppression, to prevent endoscopic recurrence of Crohn's disease following intestinal resection.METHODS: In the "POCER" study patients undergoing intestinal resection were treated with post-operative drug therapy. Two thirds were randomized to active care(6 mo colonoscopy and drug intensification for endoscopic recurrence) and one third to drug therapy without early endoscopy. Colonoscopy at 18 mo and faecal calprotectin(FC) measurement were used to assess disease recurrence. Administrative data, chart review and patient questionnaires were collected prospectively over 18 mo.RESULTS: Sixty patients(active care n = 43, standardcare n = 17) were included from one health service. Median total health care cost was $6440 per patient. Active care cost $4824 more than standard care over 18 mo. Medication accounted for 78% of total cost, of which 90% was for adalimumab. Median health care cost was higher for those with endoscopic recurrence compared to those inremission [ $ 26347( IQR 25045-27485) vs $2729(IQR 1182-5215), P < 0.001]. FC to select patients for colonoscopy could reduce cost by $1010 per patient over 18 mo. Active care was associated with 18% decreased endoscopic recurrence, costing $861 for each recurrence prevented. CONCLUSION: Post-operative management strategies are associated with high cost, primarily medication related. Calprotectin use reduces costs. The long term cost-benefit of these strategies remains to be evaluated.
文摘Living donor liver transplantation (LDLT) is now performed with high rates of success due to judicious recipient and donor selection,careful preoperative planning, excellent anesthesia management, and prompt detection and treatment of complications. The indications for LDLT for adult and pediatric recipients should be the same as for deceased donor liver transplantation. Early postoperative complications are often defined as complications occurring within the first 3
文摘AIM: To perform a systematic review and meta-analysis on post-operative complications after surgery for Crohn's disease(CD) comparing biological with no therapy.METHODS: Pub Med, Medline and Embase databases were searched to identify studies comparing postoperative outcomes in CD patients receiving biological therapy and those who did not. A meta-analysis with a random-effects model was used to calculate pooled odds ratios(OR) and confidence intervals(CI) for each outcome measure of interest. RESULTS: A total of 14 studies were included for metaanalysis, comprising a total of 5425 patients with CD 1024(biological treatment, 4401 control group). After biological therapy there was an increased risk of total infectious complications(OR = 1.52; 95%CI: 1.14-2.03, 8 studies) and wound infection(OR = 1.73; 95%CI: 1.12-2.67; P = 0.01, 7 studies). There was no increased risk for other complications including anastomotic leak(OR = 1.19; 95%CI: 0.82-1.71; P = 0.26), abdominal sepsis(OR = 1.22; 95%CI: 0.87-1.72; P = 0.25) and re-operation(OR = 1.12; 95%CI: 0.81-1.54; P = 0.46) in patients receiving biological therapy. CONCLUSION: Pre-operative use of anti-TNF-α therapy may increase risk of post-operative infectious complications after surgery for CD and in particular wound related infections.
文摘The Oral and maxillofacial region is one of the complex regions of the body considering the vast anatomical structures that are found in this region;head and neck surgery has potential for many complications, yet inadequate information on occurrence of post-operative complications in oral and maxillofacial surgeries in our setting has been documented. The aim of this study was to determine the occurrence of common early post-operative complications after oral and maxillofacial surgery in relationship to the underlying systemic condition. A descriptive postoperative study was done whereby patients who underwent oral and maxillofacial surgery were included. The included patients were those who underwent surgery for different pathological conditions, trauma, developmental/congenital conditions and inflammatory conditions to mention few. Demographic data, complications developed within one week post operative, and underlying systemic comorbidities before and after surgery were documented and analysed. A total of 102 patients were included in the study. The mean age of participants was 30.00 ± 17.01 years with a range of 2 to 81 years. Majority 43.1% (n = 44) had benign tumors with a leading diagnosis of ameloblastoma. In general, the most common complications which were noted in the cases included Pain 98% (n = 100) and Post-operative Swelling 97.1% (n = 99). The presence of underlying systemic comorbid conditions has a significant role in occurrence of some severe complications. The occurrence of complications does increase the duration of stay in the hospital hence increasing cost of treatment for which bearers are both patients and the hospital.
文摘Unrestrained anti-microbial resistance (AMR) among bacterial pathogens has made the management and treatment of post-operative wound infections difficult. This study assessed the current AMR patterns of bacterial isolates in post-operative wound infections in a tertiary care hospital in Kathmandu,Nepal. Pus swabs collected from post-operative wound infections and submitted for culture and sensitivity were included in this study. Isolation and identification of the organism was done by standard microbiological methods. Antibiotic susceptibility test was performed by Kirby Bauer disc diffusion method and result was interpreted as per National Committee for Clinical Laboratory Standards (NCCLS) guide lines. Of the 120 pus swabs processed for culture, 96 showed bacterial growth. Staphylococcus aureus 36 (37.5%) was the predominant gram positive isolate and Escherichia coli 24 (25%) was the major gram negative isolate .The infection was most prevalent in the age group 20-40 years. All S. aureus isolates were sensitive to aminoglycosides and vancomycin. Out of 36 S. aureus, 15 (41.66%) isolates were methicillin resistant S. aureus (MRSA). Staphylococcus epidermidis showed high resistance (50%-100%) to all antibiotics but were sensitive to vancomycin. All gram negative isolates showed high resistance against cephalexin (75%-100%) and ceftriaxone (25%-100%). Overall multi-drug resistant isolates were 66.7%. A high level of AMR was observed in gram negative bacterial isolates. Rational use of antibiotics and a regular monitoring of AMR patterns in post-operative wound infections are essential and mandatory to avert further emergence and spread of anti-microbial resistance among bacterial pathogens.
文摘The incidence and prevalence of cardiovascular disease(CVD)are increasing rapidly in developing countries.Most patients with CVD do not respond to medical treatment and have to undergo cardiac surgery.This highly stressful experience results in increased levels of anxiety for patients.The objective of this review was to evaluate the efficacy of massage therapy on postoperative outcomes among patients undergoing cardiac surgery.A comprehensive literature search was made on PubMed-Medline,CINAHL,Science Direct,Scopus,Web of Science and the Cochrane library databases for original research articles published between 2000 and 2015.Original articles that reported the efficacy of massage therapy in patients undergoing cardiac surgery were included.The Cochrane data extraction form was used to extract data.A total of 297 studies were identified in the literature search.However,only seven studies were eligible for analysis.Of the seven studies,six studies demonstrated the effects of massage therapy on improving postoperative outcomes of patients,while one study found no evidence of improvement.Although the methods varied considerably,most of the studies included in this review reported positive results.Therefore,there is some evidence that massage therapy can lead to positive postoperative outcomes.Evidence of the effectiveness of massage therapy in patients undergoing cardiac surgery remains inconclusive.Additional research is needed to provide a strong evidence base for the use of massage therapy to improve post-operative outcomes and recovery among cardiac surgery patients.
文摘BACKGROUND Colorectal cancer(CRC)resection is currently being undertaken in an increasing number of obese patients.Existing studies have yet to reach a consensus as to whether obesity affects post-operative outcomes following CRC surgery.AIM To evaluate the post-operative outcomes of obese patients following CRC resection,as well as to determine the post-operative outcomes of obese patients in the subgroup undergoing laparoscopic surgery.METHODS Six-hundred and fifteen CRC patients who underwent surgery at the Prince Charles Hospital between January 2010 and December 2020 were categorized into two groups based on body mass index(BMI):Obese[BMI≥30,n=182(29.6%)]and non-obese[BMI<30,n=433(70.4%)].Demographics,comorbidities,surgical features,and post-operative outcomes were compared between both groups.Postoperative outcomes were also compared between both groups in the subgroup of patients undergoing laparoscopic surgery[n=472:BMI≥30,n=136(28.8%);BMI<30,n=336(71.2%)].RESULTS Obese patients had a higher burden of cardiac(73.1%vs 56.8%;P<0.001)and respiratory comorbidities(37.4%vs 26.8%;P=0.01).Obese patients were also more likely to undergo conversion to an open procedure(12.8%vs 5.1%;P=0.002),but did not experience more postoperative complications(51.6%vs 44.1%;P=0.06)or high-grade complications(19.2%vs 14.1%;P=0.11).In the laparoscopic subgroup,however,obesity was associated with a higher prevalence of post-operative complications(47.8%vs 39.3%;P=0.05)but not high-grade complications(17.6%vs 11.0%;P=0.07).CONCLUSION Surgical resection of CRC in obese individuals is safe.A higher prevalence of post-operative complications in obese patients appears to only be in the context of laparoscopic surgery.
文摘Introduction: Fibroid benign tumour of the uterus can be operated either by laparotomy or laparoscopy. Laparoscopy is not well vulgarised in our settings. Objective: The main objective was to compare the surgical and post-operative outcomes of laparoscopic versus abdominal myomectomy. Methods: We performed a comparative analytical cross sectional study from 1st January 2016 to 31st March 2018 consisted of two groups: group 1 of women who underwent laparoscopic myomectomy (LM) and group 2 of women who underwent abdominal myomectomy (AM). The data collected was entered in Epi Info 7.2 version and exported to IBM SPSS Statistics version 22 for analysis. We used alpha error margin of 5% and confidence interval of 95%. Results: We enrolled 50 cases of myomectomy consisted of 33 (66.0%) files for AM and 17 (34.0%) files for LM. The clinical presentation of fibroid was similar in both groups. The main operation time (H) was (1.27 ± 0.13) for laparoscopy which is much less than (2.05 ± 0.07) for laparotomy group (p = 0.006). In AM group we had 04 post-operatory complications against zero complications in LM group but the difference was not statistically significant (p = 0.387). In the second look laparoscopy, the types of adhesions were not statistically significant (p = 0.471). Conclusion: Laparoscopic offers advantages compared to abdominal myomectomy.
文摘Background: Ileal perforation is a very critical condition. Objectives: The purpose of the present study was to see the post-operative mortality after ileal perforation. Methodology: This prospective cohort study was conducted in the Department of Surgery at Dhaka Medical College Hospital, Dhaka, Bangladesh from September 2000 to December 2002 for period of 2 years and 3 months. All the patients presented with ileal perforation at any age with both sexes were included in this study. Patients were selected consecutively and the patients who showed ileal perforation at laparotomy were included in this study. Preoperative diagnosis was based on detailed history, complete physical examinations supported by plain x-ray abdomen in erect posture including both domes of diaphragm. After immediate resuscitation surgical treatment was undertaken as soon as possible following admission in all cases. The patients were followed up and the mortality profiles were recorded after surgical intervention. Result: Out of 53 patients having postoperative complications 38 patients were survived and 15 patients were expired. So total survivors were 85% and non-survivors 15%. In this study most of the mortality (12%) was attributed to septicemia and mode of death was multiple organ failure. Respiratory complications caused 2% mortality one patient died of ARDS and another elderly patient with preexisting bronchial asthma developed respiratory failure and was unresponsive to treatment. One death was related to faecal fistula followed by severe fluid, electrolyte and acid-base imbalance with peritonitis and gross sepsis. Conclusion: In conclusion, the mortality is significantly high due to septicemia, ARDS and faecal fistula.
文摘BACKGROUND Atrial fibrillation(AF)is the most common arrhythmia developing in postoperative patients.Limited data are available regarding pre-operative risk factors and prognostic impact of post-operative AF(POAF)following hip fracture surgery(HFS)in Korean population.AIM We aimed to investigate the incidence,predictors,and hospital prognosis of POAF in HFS patients.METHODS This study included 245 patients without history of AF who underwent HFS between August 2014 and November 2016.POAF was defined as new-onset AF that occurred during hospitalization after HFS.RESULTS Twenty patients(8.2%)experienced POAF after HFS.POAF developed on median post-operative day 2(interquartile range,1–3).Multivariable logistic regression analysis showed that age[odds ratio(OR),1.111;95%confidence interval(CI),1.022–1.209],chronic obstructive pulmonary disease(COPD)(OR,6.352;95%CI,1.561–25.841)and E/e’ratio(OR,1.174;95%CI,1.002–1.376)were significant predictors of POAF.Patients with POAF had a significantly higher intensive care unit admission rate(55.0%vs 14.7%,P<0.001)and incidence of congestive heart failure(45.0%vs 10.7%,P<0.001).In multivariable logistic regression analysis,POAF was significantly associated with increased incidence of congestive heart failure(OR,4.856;95%CI,1.437–16.411)and intensive care unit admission(OR,6.615;95%CI,2.112–20.718).CONCLUSION POAF was frequently developed in elderly patients following HFS.Age,COPD and elevated E/e’ratio were found as significant predictors of POAF in HFS patients.Patients with POAF significantly experienced intensive care unit admission and incident congestive heart failure during hospitalization.
文摘Chronic post-operative pain is a recognized adverse consequence of surgery;managing and preventing it are always a better choice. Proper choice of Anesthetic technique, use of combined anesthesia and pre-emptive analgesia may prevent and decrease the incidence of chronic post-operative pain. Transverse abdominis plane block (TAP Block) is a regional anesthesia technique following abdominal surgeries which involve injection of a large amount of local anesthetics in TAP, an anatomical space between the internal oblique and transverse abdominis muscle. The aim of this review is to show the effect and uses of TAP block as a combined anesthesia and multimodal analgesia in preventing chronic post-operative pain.
文摘Introduction: In spite of the use of the less and less invasive and the more and more effective techniques and the use of fast rehabilitation conditions of the patients in surgery, the post-operative complications (POC) stay the main reasons of admission in resuscitation service. Objective: To determine the post-operative outcome of the patients admitted in resuscitation. Patient and method: It was about a retrospective and transverse survey from June 2017 to May 2018 in the service of polyvalent resuscitation of the academic hospital center of Gabriel Touré. Have been included the patients operated for surgical or obstetric gynecology—pathologies admitted in resuscitation for post-operative complications established or potential precocious or late. The used statistical test was the Chi2 with p Results: During the period, 514 patients have been admitted in resuscitation of which 140 cases of post-operatively represented 27.2% of the admissions. Under hospitalization 35.7% of patients have presented a complication. The middle age of patients was 37.72 ± 20.9 years. The sex ratio was 0.70. The middle length of interventions was 122 ± 83 min with extremes going from 20 to 434 min. The predominant admission motive was hemodynamic instability. The delay of appearance intervening of the complications was 3 days in 94%. The predominant complications were: respiratory (32%), infectious (28%) and Cardiovascular (20%). The middle length of hospitalization was of 3.36 ± 2.90 days. The death rate was 15%. The complications were related age, the class of Alteme?er, the ASA, and the perioperative undesirable events with p Conclusion: The post-operative admissions in resuscitation are frequent including several factors of morbi-mortality. A better management per and postoperative of the patients operated would reduce the death rate. The profile mark is the one of a patient admitted for hemodynamic instability.
文摘A 62-year-old female complained of vision loss following multiple abdominal surgeries for mesenteric ischemia. The patient’s visual acuity was no light perception (NLP) in the right eye and hand motion (HM) at 1’ in the left eye. Both pupils were unreactive and no relative afferent pupillary defect was noted. Anterior segment and fundus examination were unremarkable. T1 and T2 weighted MRI imaging of the brain was normal but diffusion weighted imaging (DWI) revealed areas of bright signal within both intraorbital optic nerves, confirming the diagnosis of posterior ischemic optic neuropathy.
文摘Introduction: Post-operative (post-op) complete atrio-ventricular heart block (CAVB) occurs after 1% - 4% of pediatric cardiac operations. Current practice dictates implantation of permanent pacemaker (PPM) when post-op CAVB persists >9 days. We propose that earlier PPM implantation may be the most cost-effective methodology since patient costs increase with extended length of stay (LOS). Methods: Data on the probabilities of persistent post-op CAVB were extracted from published reports. No individual patient data were utilized during this study. This was utilized to create a decision-making model and a total cost analysis on post-op day 0 - 10 to determine the most cost-efficient day to implant a PPM. Cost variables included estimates of daily cardiac ICU care, cost of PPM implantation, LOS, cost related to possible superficial or deep infection based on published prevalence rates (2.3% and 4.9%, respectively) and need for explant due to deep infection or recovery of native conduction. The model assumes 5-day minimum LOS and 1 day increase in LOS with PPM implantation. Cost data were obtained from relevant billing codes and manufacturer list prices for PPM and leads. A secondary analysis evaluated probability of unnecessary PPMs implanted and excess costs. Results: Post-op day (POD) 4 is the lowest total cost of PPM implantation for post-op CAVB, even when accounting for possible risk of either superficial or deep infection. A one-way sensitivity analysis accounting for variability of cardiac ICU care costs between centers ranging from $3000 - $9000 per day consistently replicates POD 4 as the most cost-effective day for PPM implantation. Implant on POD 4 results in a 26% chance of unnecessary implantation. Conclusions: The most cost-efficient day for PPM implantation for post-op CAVB is post-op day 4, which results in a minimum total cost savings of $17,422 per patient. Added costs due to risk of superficial or deep infection are marginal due to low prevalence of post-operative infection in this population.
文摘Background: Postoperative wound healing has been a problem which causes high mortality in the developing world;postoperative wound has been reported to cause devastating consequences and a measurable mortality. There is a limited number of published studies in Tanzania investigating Nursing practice on post-operative wound care in surgical wards at Muhimbili National Hospital, Dar-es-Salaam, Tanzania. This study assesses nursing practice on postoperative wound care by nurses in surgical wards at Muhimbili National Hospital. Methods: A cross-sectional study of surgical nurses was carried out through the use of randomly selected surgical wards at Muhimbili National Hospital in Tanzania from September 2011 to July 2013. A multistage cluster sampling technique was used to obtain a suitable number of study participants. Data collection was done using a checklist from a convenient sample of 71 nurses in selected surgical wards. Results: The result indicates that a big number of the participants were female (76.5%) and those of the age group 25 to 34 years were 40.8%. Participants exceeding a half of the selected sample reported to have poor post-operative wound care practice (57.7%). In comparison, male participants scored higher, and had better practice than their female counterparts, however, there was no considerable difference in the scores (P = 0.803). During set-up and preparation phase, the washing of hands before starting and after the completion of procedure was taken into consideration by less than half of the participants (49.3%). All participants did not ensure the environment is clean and take into account the patient’s privacy through the use of screen or even closing the room. The report shows that nurses take into consideration putting on clean gloves during the removal of the old dressing (99%), the use of sterile gloves during wound dressing was taken into consideration by most of the nurses (63%). Good practice was noted in applying dressing solution as recommended (85%), dry sterile dressing was applied by (90%), arrangement and setting up of dressing forceps and other items that may be needed in order of their application using forceps (20%), usage of forceps to dip gauze into antiseptic solution (35%) and cleaning of the wound cleaning from least contaminated to most contaminated area was only adhered to by (34%). Post-operative counseling and giving to the patient not to temper with the wound was done by a representation of only 15% of nurses. All the nurses did not do the documentation of the changes observed on the wound nor did they report on the patients comfort and the date and time after the procedure wound changes, reported patient comfort, and recorded date or time after the procedure. Conclusion: Majority of the nurses in surgical wards do not follow the postoperative wound care checklist provided by MNH although they know its importance. Assessment of the wound and documentation continues to be a problem in the nursing profession in Tanzania. Nurses are reasonably knowledgeable about the principal of wound dressing;however, lack of knowledge on some of the key principles of wound dressing is worth noting. Almost half of the nurses do not wash hands before and after the procedures, they don’t use single gauze in one direction only, not cleaning from least contaminated to most contaminated area, which can lead to wound contamination.
文摘Permanent post-operative cognitive dysfunction (POCD) is a grim outcome to an estimated 6% of elderly surgical patients. Volatile anesthetics impact neuronal tissue independent of effects attributed to the physical trauma of the surgery itself. While it is recognized that all aspects related to surgery may contribute to cognitive loss in some manner, the present paper focuses on the role of volatile anesthetics in promoting POCD. There is an increased risk of onset and progression of Alzheimer’s disease (AD) from POCD, implying that the neuropathogenesis between the two is similar. Human studies, being ethically limited in scope, require animal models as a substitute. While the literature using rodent models contains valuable information, we believe that the accessible and practical zebrafish will greatly enhance our further understanding of the molecular mechanism of POCD as it relates to AD. Disease genes and fundamental neurobehaviors of these teleost fish mirror those of mammals and humans, validating their use as a core research model for AD. Since the gradual senescence seen in zebrafish also resembles that found in humans, we numerically correlated the two lifespans, offering researchers a computational tool. Zebrafish, being aquatic animals, necessitates the use of miscible compounds, such as trifluoroethanol, whose anesthetic potency we are presenting. We also review the rodent and zebrafish literature relevant to POCD. Continued research with the leading-edge zebrafish unlocks the possibility that, in the future, perioperative intervention will prevent POCD.
文摘Objectives: Adequate control of hemodynamic parameters in patients undergoing otolaryngology-head and neck (OLHN) surgeries is one of the objectives of peri-operative anesthesia management. In this context, we seek to evaluate the effectiveness of metoprolol compared to clonidine in the post-<span>operative control of systolic (SBP) and diastolic (DBP) blood pressures, and </span><span>heart rate (HR), when these medications are used in the immediate </span><span>pre-operative period. Method: this is a randomized double-blind clinical trial. Patients over 18 years old, according to the American Society of Anesthesiologists Physical Status Classification (ASA) I or II, who would undergo OLHN surgery, presenting with greater than 140 mmHg (SBP) or 90 mmHg (DBP), upon arrival at the surgical ward, were included in the study. 46 patients were randomized into two groups (C or M) who received clonidine (75 or 150 mcg) or metoprolol (5 or 10 mg), respectively. The averages of SBP, DBP and HR were compared between groups upon arrival at the post anesthesia care unit (PACU) and four hours post-surgery. Results: In group C, SBP (127.7 </span><span>±</span><span> 18.8 vs 137.3 </span><span>±</span><span> 14.1 mmHg, p = 0.03) and DBP (73.1 </span><span>±</span><span> 15.46 vs 82.6 </span><span>±</span><span> 7.9 mmHg, p <</span><span> </span><span>0.01) were lower, when compared with group M. No difference was observed in HR immediately upon PACU arrival. In addition, for four hours post-surgery, no change was noted in the SBP, DBP or HR. Conclusion: metoprolol was less effective than clonidine in reducing systolic and diastolic blood pressures in the immediate post-operative period of OLHN surgeries.</span>
