Anemic patients undergoing surgery are likely to receive blood transfusion, increasing morbidity and mortality. Prevalence of anemia in cardiac surgical patients are studied extensively, however its burden in RVHD is lacking. This study attempted to investigate the prevalence of preoperative anemia in RVHD and its effect on blood transfusion, morbidity and mortality in patients undergoing valve surgery. Methods: This is a retrospective observational study conducted at a tertiary care hospital in Nepal. We considered 340 patients who underwent Rheumatic valve replacement surgery from 2014 January to December 2016 and data on their socio-demographic and clinical characteristics were extracted from the patient’s records. The analyses meeting the study objectives were conducted using IBM SPSS v25 for Windows (IBM Statistical Package for Social Sciences, 2015IBM Corporation, New York, United States). Results: The prevalence of no anemia, mild, moderate, and severe anemia was 34.1%, 57.7%, 39.6%, 2.5%, respectively. The units of Red Blood Cell used for transfusion were 1.2 units, 2.0 units, 2.3 units, and 1.6 units in patients without anemia, and those with mild, moderate and severe anemia respectively. The incidence of reexploration was higher in patients with severe anemia as compared to the non anemic with an incidence of 66.6%. A proportion of the patients with no anemia, mild, moderate and severe anemia with less than 7 days stay in the intensive care unit were 89%, 82%, 84.7% and 100% respectively. The length of hospital stay more than 10 days was seen in 58.9%, 71.6%, 63% and 100% in patients with no anemia, mild, moderate and severe anemia. An overall incidence of mortality in anemic patients was 11% while in non anemic patients was 5.3%. Conclusions: The prevalence of anemia was high in the Nepalese patients with Rheumatic valvular heart disease planned for elective surgery. There was an increased incidence of blood transfusion, longer hospital stay, and increased mortality in anemic patients compared to their non anemic counterparts.展开更多

We hypothesized that AKI occurs mainly due to perioperative risk factors and may affect outcome.AIM To assess peri-operative risk factors for AKI post cardiac surgery and its relationship with clinical outcome.METHODS This was an observational single center, tertiary care setting study, which enrolled 206 consecutive patients, admitted to ICU after cardiac surgery. Patients were followed-up until ICU discharge or death, in order to determine the incidence of AKI, perioperative risk factors for AKI and its association with outcome.Univariate and multivariate logistic regression analysis was performed to assess predictor variables for AKI development.RESULTS After ICU admission, 55 patients(26.7%) developed AKI within 48 h. From the logistic regression analysis performed, high EuroScore Ⅱ(OR: 1.18;95%CI: 1.06-1.31, P = 0.003), white blood cells(WBC) pre-operatively(OR: 1.0;95%CI: 1.0-1.0, P = 0.002) and history of chronic kidney disease(OR: 2.82;95%CI: 1.195-6.65, P = 0.018) emerged as independent predictors of AKI among univariate predictors. AKI that developed AKI had longer duration of mechanical ventilation [1113(777–2195) vs 714(511–1020) min, P = 0.0001] and ICU length of stay [70(28–129) vs 26(21–51) h, P = 0.0001], higher rate of ICU-acquired weakness(16.4% vs 5.3%, P =0.015), reintubation(10.9% vs 1.3%, P = 0.005), dialysis(7% vs 0%, P = 0.005), delirium(36.4% vs 23.8%, P = 0.001) and mortality(3.6% vs 0.7%, P = 0.046).CONCLUSION Patients present frequently with AKI after cardiac surgery. EuroScore Ⅱ, WBC count and chronic kidney disease are independent predictors of AKI development. The occurrence of AKI is associated with poor outcome.展开更多

All patients with carcinomawere confirmed pathologically.Results: In 44 patients with liver cancer (76tumors), the diagnostic rate of intraoperative ultra-sonography was 97% (74/76), which was markedlyhigher than 84% (64/76) of preoperative ultra-sonography (P【0.05). The diagnostic rate (92%;22/24) of intraoperative ultrasonography for tumors≤2 cm in diameter was markedly higher than that(54%; 13/24) of preoperative ultrasonography (P【0.01). The diagnostic rate (94%; 16/17) of intra-operative ultrasonography for tumor embulus of thevein was also markedly higher than that (53%; 9/17) of preoperative ultrasonography (P【0.01). Thediagnostic rates of intraoperative and preoperativeultrasonography for cholelithiasis were 99% (108/109) and 97% (106/109) respectively (P】0.05).Yet the diagnostic rate (100%; 12/12) of intraopera-tive ultrasonography for gallbladder carcinoma wasmarkedly higher than that (66.7%; 8/12) of pre-operative ultrasonography (P【0.05). The diagnos-tic rates of intraoperative ultrasonography for chole-docholith and biliary tract cancer were all 100%,markedly higher than those (83%; 20/24 and 75%;12/16) of preoperative ultrasonography (P【0.05).Conclusions: Intraoperative ultrasonography canraise the detective rate of the liver occupying lesionscomparing with that of preoperative untrasonogra-phy. It is of valuable in selecting operative schemeand locating small lesions.展开更多

It describes an approach to the neurofascial plane of the transverse abdominal muscle via the Jean-Louis Petit triangle and provides analgesia of the entire homolateral hemi abdomen. The aim of our study was to compare post-operative analgesia and post-operative morphine requirements between transverse abdominal plane block (TAP) and peri-orificial infiltration during laparoscopic abdominal surgery. Material and method: Prospective, randomized study conducted over a 2-year period. The study was conducted in the operating theatre of the Saint Louis Regional Hospital in Senegal. All adult patients undergoing laparoscopic abdominal surgery were included. Clinical aspects, pain scales and morphine consumption were analyzed. Results: A total of 60 patients were enrolled: 30 patients in the TAP group and 30 patients in the infiltration group. The average age was 32.9 years. The indications for laparoscopy were acute appendicitis in 50% of cases, gallbladder stones in 16% and inguinal hernia in 8%. For the TAP group, the mean numerical pain scale was 3.9 at 6 hours post-operatively and 2.1 at 24 hours post-operatively. For the infiltration group, the mean numerical pain scale was 4.3 at 6 hours post-op and 3 at 24 hours post-op. Morphine consumption at 6 hours post-op was on average 0.4 mg/patient for the TAP group and 0.9 mg/patient for the infiltration group. Discussion/conclusion: Analgesia provided by ultrasound-guided TAP block for laparoscopic abdominal surgery appears to be identical to periorificial infiltration. However, the simplicity and reproducibility of ultrasound-guided TAP block gives it a definite advantage.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BACKGROUND Colorectal cancer is a major global health challenge that predominantly affects older people.Surgical management,despite advancements,requires careful consideration of preoperative patient status for optimal outcomes.AIM To summarize existing evidence on the association of frailty with short-term postoperative outcomes in patients undergoing colorectal cancer surgery.METHODS A literature search was conducted using PubMed,EMBASE and Scopus databases for observational studies in adult patients aged≥18 years undergoing planned or elective colorectal surgery for primary carcinoma and/or secondary metastasis.Only studies that conducted frailty assessment using recognized frailty assess-ment tools and had a comparator group,comprising nonfrail patients,were included.Pooled effect sizes were reported as weighted mean difference or relative risk(RR)with 95%confidence intervals(CIs).RESULTS A total of 24 studies were included.Compared with nonfrail patients,frailty was associated with an increased risk of mortality at 30 d(RR:1.99,95%CI:1.47-2.69),at 90 d(RR:4.76,95%CI:1.56-14.6)and at 1 year(RR:5.73,95%CI:2.74-12.0)of follow up.Frail patients had an increased risk of any complications(RR:1.81,95%CI:1.57-2.10)as well as major complications(Clavien-Dindo classification grade≥III)(RR:2.87,95%CI:1.65-4.99)compared with the control group.The risk of reoperation(RR:1.18,95%CI:1.07-1.31),readmission(RR:1.70,95%CI:1.36-2.12),need for blood transfusion(RR:1.67,95%CI:1.52-1.85),wound complications(RR:1.49,95%CI:1.11-1.99),delirium(RR:4.60,95%CI:2.31-9.16),risk of prolonged hospitalization(RR:2.09,95%CI:1.22-3.60)and discharge to a skilled nursing facility or rehabilitation center(RR:3.19,95%CI:2.0-5.08)was all higher in frail patients.CONCLUSION Frailty in colorectal cancer surgery patients was associated with more complications,longer hospital stays,higher reoperation risk,and increased mortality.Integrating frailty assessment appears crucial for tailored surgical management.
文摘BACKGROUND Cardiovascular disease is the most prevalent disease worldwide and places a great burden on the health and economic welfare of patients.Cardiac surgery is an important way to treat cardiovascular disease,but it can prolong mechanical ventilation time,intensive care unit(ICU)stay,and postoperative hospitalization for patients.Previous studies have demonstrated that preoperative inspiratory muscle training could decrease the incidence of postoperative pulmonary complications.AIM To explore the effect of preoperative inspiratory muscle training on mechanical ventilation time,length of ICU stay,and duration of postoperative hospitalization after cardiac surgery.METHODS A literature search of PubMed,Web of Science,Cochrane Library,EMBASE,China National Knowledge Infrastructure,WanFang,and the China Science and Technology journal VIP database was performed on April 13,2022.The data was independently extracted by two authors.The inclusion criteria were:(1)Randomized controlled trial;(2)Accessible as a full paper;(3)Patients who received cardiac surgery;(4)Preoperative inspiratory muscle training was implemented in these patients;(5)The study reported at least one of the following:Mechanical ventilation time,length of ICU stay,and/or duration of postoperative hospitalization;and(6)In English language.RESULTS We analyzed six randomized controlled trials with a total of 925 participants.The pooled mean difference of mechanical ventilation time was-0.45 h[95%confidence interval(CI):-1.59-0.69],which was not statistically significant between the intervention group and the control group.The pooled mean difference of length of ICU stay was 0.44 h(95%CI:-0.58-1.45).The pooled mean difference of postoperative hospitalization was-1.77 d in the intervention group vs the control group[95%CI:-2.41-(-1.12)].CONCLUSION Preoperative inspiratory muscle training may decrease the duration of postoperative hospitalization for patients undergoing cardiac surgery.More high-quality studies are needed to confirm our conclusion.
文摘AIM:To measure the difference of intraoperative central macular thickness(CMT)before,during,and after membrane peeling and investigate the influence of intraoperative macular stretching on postoperative best corrected visual acuity(BCVA)outcome and postoperative CMT development.METHODS:A total of 59 eyes of 59 patients who underwent vitreoretinal surgery for epiretinal membrane was analyzed.Videos with intraoperative optical coherence tomography(OCT)were recorded.Difference of intraoperative CMT before,during,and after peeling was measured.Pre-and postoperatively obtained BCVA and spectral-domain OCT images were analyzed.RESULTS:Mean age of the patients was 70±8.13y(range 46-86y).Mean baseline BCVA was 0.49±0.27 log MAR(range 0.1-1.3).Three and six months postoperatively the mean BCVA was 0.36±0.25(P=0.01 vs baseline)and 0.38±0.35(P=0.08 vs baseline)log MAR respectively.Mean stretch of the macula during surgery was 29%from baseline(range 2%-159%).Intraoperative findings of macular stretching did not correlate with visual acuity outcome within 6mo after surgery(r=-0.06,P=0.72).However,extent of macular stretching during surgery significantly correlated with less reduction of CMT at the fovea centralis(r=-0.43,P<0.01)and 1 mm nasal and temporal from the fovea(r=-0.37,P=0.02 and r=-0.50,P<0.01 respectively)3mo postoperatively.CONCLUSION:The extent of retinal stretching during membrane peeling may predict the development of postoperative central retinal thickness,though there is no correlation with visual acuity development within the first 6mo postoperatively.

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:While a rushed operation can omit essential procedures,prolonged operative time results in higher morbidity.Nevertheless,the optimal operative time range remains uncertain.This study aimed to estimate the ideal operative time range and evaluate its applicability in laparoscopic cancer surgery.Methods:A prospectively collected multicenter database of 397 patients who underwent laparoscopic distal gastrectomy were retrospectively reviewed.The ideal operative time range was statistically calculated by separately analyzing the operative time of uneventful surgeries.Finally,intraoperative and postoperative outcomes were compared among the shorter,ideal,and longer operative time groups.Results:The statistically calculated ideal operative time was 135.4-165.4 min.The longer operative time(LOT)group had a lower rate of uneventful,perfect surgery than the ideal or shorter operative time(IOT/SOT)group(2.8%vs.8.8%and 2.2%vs.13.4%,all P<0.05).Longer operative time increased bleeding,postoperative morbidities,and delayed diet and discharge(all P<0.05).Particularly,an uneventful,perfect surgery could not be achieved when the operative time exceeded 240 min.Regardless of ideal time range,SOT group achieved the highest percentage of uneventful surgery(13.4%),which was possible by surgeon's ability to retrieve a higher number of lymph nodes and perform≥150 gastrectomies annually.Conclusions:Operative time longer than the ideal time range(especially≥240 min)should be avoided.If the essential operative procedure were faithfully conducted without compromising oncological safety,an operative time shorter than the ideal range leaded to a better prognosis.Efforts to minimize operative time should be attempted with sufficient surgical experience.

文摘Background:Prolonged preoperative fasting can cause hypoglycemia,hyperglycemia,and intravascular volume depletion in children.We aimed to examine whether prolonged preoperative fasting is associated with in-hospital mortality and other morbidities in pediatric cardiothoracic surgery.Methods:This retrospective cohort study included children aged 0–3 years who underwent cardiac surgery between July 2014 and October 2020.The patient demographic data,surgery-related and anesthesia-related factors,and postoperative outcomes,including hypoglycemia,hyperglycemia,sepsis,length of intensive care unit stay,and in-hospital mortality,were recorded.The main exposure and outcome variables were prolonged fasting and time-to-death after surgery,respectively.The associations between prolonged fasting and perioperative death were analyzed using multivariate Cox regression analysis.Results:In total,402 patients were recruited.The incidence of perioperative mortality was 21%(85/402).The proportion of perioperative deaths was significantly higher in the prolonged fasting group than that in the normal fasting group.The proportion of postoperative bacteremia and hypoglycemia was significantly higher in the very prolonged fasting group than that in the prolonged fasting group.After adjusting for preoperative conditions and anesthesia-and surgery-related factors,preoperative prolonged fasting>14.4 h was significantly associated with time-to-death(HR[95%CI]:2.2[1.2,3.9],p=0.036).The 30-day survival rates of fasting time>14.4 h,9.25–14.4 h,and<9.25 h were 0.67(0.55,0.81),0.79(0.72,0.87),and 0.85(0.79,0.91),respectively.Conclusions:Preoperative fasting of more than 14.4 h was associated with a two-fold increase in the hazard rate of time-to-death in children who underwent cardiac surgery.

文摘BACKGROUND Enhanced recovery after surgery strategies are increasingly implemented to improve the management of surgical patients.AIM To evaluate the effects of new perioperative fasting protocols in children≥3 mo of age undergoing non-gastrointestinal surgery.METHODS This prospective pilot study included children≥3 mo of age undergoing nongastrointestinal surgery at the Children’s Hospital(Zhejiang University School of Medicine)from January 2020 to June 2020.The children were divided into either a conventional group or an ERAS group according to whether they had been enrolled before or after the implementation of the new perioperative fasting strategy.The children in the conventional group were fasted using conventional strategies,while those in the ERAS group were given individualized fasting protocols preoperatively(6-h fasting for infant formula/non-human milk/solids,4-h fasting for breast milk,and clear fluids allowed within 2 h of surgery)and postoperatively(food permitted from 1 h after surgery).Pre-operative and postoperative fasting times,pre-operative blood glucose,the incidence of postoperative thirst and hunger,the incidence of perioperative vomiting and aspiration,and the degree of satisfaction were evaluated.RESULTS The study included 303 patients(151 in the conventional group and 152 in the ERAS group).Compared with the conventional group,the ERAS group had a shorter pre-operative food fasting time[11.92(4.00,19.33)vs 13.00(6.00,20.28)h,P<0.001],shorter preoperative liquid fasting time[3.00(2.00,7.50)vs 12.00(3.00,20.28)h,P<0.001],higher preoperative blood glucose level[5.6(4.2,8.2)vs 5.1(4.0,7.4)mmol/L,P<0.001],lower incidence of thirst(74.5%vs 15.3%,P<0.001),shorter time to postoperative feeding[1.17(0.33,6.83)vs 6.00(5.40,9.20),P<0.001],and greater satisfaction[7(0,10)vs 8(5,10),P<0.001].No children experienced perioperative aspiration.The incidences of hunger,perioperative vomiting,and fever were not significantly different between the two groups.CONCLUSION Optimizing fasting and clear fluid drinking before non-gastrointestinal surgery in children≥3 mo of age is possible.It is safe and feasible to start early eating after evaluating the recovery from anesthesia and the swallowing function.
文摘BACKGROUND Obesity is a state in which excess heat is converted into excess fat,which accumulates in the body and may cause damage to multiple organs of the circulatory,endocrine,and digestive systems.Studies have shown that the accumulation of abdominal fat and mesenteric fat hypertrophy in patients with obesity makes laparoscopic surgery highly difficult,which is not conducive to operation and affects patient prognosis.However,there is still controversy regarding these conclusions.AIM To explore the relationship between body mass index(BMI)and short-term prognosis after surgery for colorectal cancer.METHODS PubMed,Embase,Ovid,Web of Science,CNKI,and China Biology Medicine Disc databases were searched to obtain relevant articles on this topic.After the articles were screened according to the inclusion and exclusion criteria and the risk of literature bias was assessed using the Newcastle-Ottawa Scale,the prognostic indicators were combined and analyzed.RESULTS A total of 16 articles were included for quantitative analysis,and 15588 patients undergoing colorectal cancer surgery were included in the study,including 3775 patients with obesity and 11813 patients without obesity.Among them,12 articles used BMI≥30 kg/m^(2)and 4 articles used BMI≥25 kg/m^(2)for the definition of obesity.Four patients underwent robotic colorectal surgery,whereas 12 underwent conventional laparoscopic colorectal resection.The quality of the literature was good.Meta-combined analysis showed that the overall complication rate of patients with obesity after surgery was higher than that of patients without obesity[OR=1.35,95%CI:1.23-1.48,Z=6.25,P<0.0001].The incidence of anastomotic leak after surgery in patients with obesity was not significantly different from that in patients without obesity[OR=0.99,95%CI:0.70-1.41),Z=-0.06,P=0.956].The incidence of surgical site infection(SSI)after surgery in patients with obesity was higher than that in patients without obesity[OR=1.43,95%CI:1.16-1.78,Z=3.31,P<0.001].The incidence of reoperation in patients with obesity after surgery was higher than that in patients without obesity;however,the difference was not statistically significant[OR=1.15,95%CI:0.92-1.45,Z=1.23,P=0.23];Patients with obesity had lower mortality after surgery than patients without obesity;however,the difference was not statistically significant[OR=0.61,95%CI:0.35-1.06,Z=-1.75,P=0.08].Subgroup analysis revealed that the geographical location of the institute was one of the sources of heterogeneity.Robot-assisted surgery was not significantly different from traditional laparoscopic resection in terms of the incidence of complications.CONCLUSION Obesity increases the overall complication and SSI rates of patients undergoing colorectal cancer surgery but has no influence on the incidence of anastomotic leak,reoperation rate,and short-term mortality rate.
文摘BACKGROUND Perforated peptic ulcer(PPU)is a common emergency surgical condition and a significant cause of morbidity and mortality worldwide.While advances in surgical techniques have improved outcomes for patients with PPU,many factors still affect postoperative hospital stay and overall prognosis.One potential factor is the serum albumin(SA)level,a widely utilized marker of nutritional status that has been associated with length of stay and complications in various surgical procedures.AIM To clarify the correlation of SA level on postoperative day 2 with hospital length of stay(HLOS)in patients undergoing emergency surgery for perforated peptic ulcer(PPU).METHODS We retrospectively collected and analyzed clinical baseline data,including blood routine and SA levels,of patients who underwent emergency PPU surgery and postoperative treatment at the Lingnan Hospital,the Third Affiliated Hospital of Sun Yat-sen University between December 2012 and September 2021.Patients were grouped according to HLOS with 7 d as the cut-off value,and relevant indicators were analyzed using SPSS 26.0.RESULTS Of the 37 patients undergoing emergency surgery for PPU referred to our department,33 had gastric and 4 had duodenal ulcer perforation.The median HLOS was 10 d.There were 8 patients in the≤7-d group(median HLOS:7 d)and 29 patients in the>7-d group(median HLOS:10 d).The≤7-d group had markedly higher SA on postoperative day 2 than the>7-d group(37.7 g/L vs 32.6g/L;P<0.05).The SA level on postoperative day 2 was a protective factor for patients with HLOS>7 d(Odds ratio=0.629,P=0.015).The cut-off of SA on postoperative day 2 was 30.6g/L,with an area under the curve of 0.86 and a negative predictive value of 100%for the prediction of HLOS≤7 d.CONCLUSION The SA level on postoperative day 2 was associated with the HLOS in patients undergoing emergency surgery for PPU.The pre-and post-operative albumin levels should be monitored,and infusion of human SA should be considered in a timely manner.

文摘Objective:To explore the clinical effect of perioperative nursing guided by the concept of enhanced recovery after surgery and summarize them.Methods:Pubmed,Chinese National Knowledge Infrastructure(CNKI),Chinese Biomedical Literature Database(CBM),Wanfang Database,and VIP Database were searched to obtain the relevant literature involving enhanced recovery after surgery(ERAS)guidance,obtain the effective clinical data,review the reports in literature,and obtain the effective scheme.Results:Compared with the traditional nursing program,perioperative nursing principles guided by the concept of ERAS provide more accurate nursing care to patients and reduce the occurrence of intraoperative stress events through comprehensive nursing measures such as preoperative pre-rehabilitation measures,intraoperative body temperature and fluid management,postoperative analgesia,prevention of nausea and vomiting,early mobilization,catheter nursing,and better out-of-hospital follow-up.Conclusions:Perioperative nursing principles guided by the concept of ERAS can significantly reduce the incidence of perioperative complications,shorten the hospital stay of patients,and promote postoperative rehabilitation of patients.The transformation and implementation of this concept can bring significant benefits to hospitals,medical care,and patients.
文摘Background: Rheumatic Valvular Heart disease (RVHD) is common in developing countries often associated with anemia;however its burden is often overlooked. Anemic patients undergoing surgery are likely to receive blood transfusion, increasing morbidity and mortality. Prevalence of anemia in cardiac surgical patients are studied extensively, however its burden in RVHD is lacking. This study attempted to investigate the prevalence of preoperative anemia in RVHD and its effect on blood transfusion, morbidity and mortality in patients undergoing valve surgery. Methods: This is a retrospective observational study conducted at a tertiary care hospital in Nepal. We considered 340 patients who underwent Rheumatic valve replacement surgery from 2014 January to December 2016 and data on their socio-demographic and clinical characteristics were extracted from the patient’s records. The analyses meeting the study objectives were conducted using IBM SPSS v25 for Windows (IBM Statistical Package for Social Sciences, 2015IBM Corporation, New York, United States). Results: The prevalence of no anemia, mild, moderate, and severe anemia was 34.1%, 57.7%, 39.6%, 2.5%, respectively. The units of Red Blood Cell used for transfusion were 1.2 units, 2.0 units, 2.3 units, and 1.6 units in patients without anemia, and those with mild, moderate and severe anemia respectively. The incidence of reexploration was higher in patients with severe anemia as compared to the non anemic with an incidence of 66.6%. A proportion of the patients with no anemia, mild, moderate and severe anemia with less than 7 days stay in the intensive care unit were 89%, 82%, 84.7% and 100% respectively. The length of hospital stay more than 10 days was seen in 58.9%, 71.6%, 63% and 100% in patients with no anemia, mild, moderate and severe anemia. An overall incidence of mortality in anemic patients was 11% while in non anemic patients was 5.3%. Conclusions: The prevalence of anemia was high in the Nepalese patients with Rheumatic valvular heart disease planned for elective surgery. There was an increased incidence of blood transfusion, longer hospital stay, and increased mortality in anemic patients compared to their non anemic counterparts.

文摘Purpose:This study sought to explore the effect of intraoperative mean blood glucose levels and variability on postoperative acute kidney injury(AKI)in children undergoing congenital cardiac surgery.Methods:We conducted a prospective nested case-control study in children(age<18 years)undergoing congenital heart surgery with cardiopulmonary bypass(CPB)at the Fuwai Hospital between April 01,2022 and July 30,2022.Cases were individuals who developed AKI within the first postoperative 7 days(AKI group)and controls were those without AKI(Non-AKI group)according to KDIGO criteria.AKI and Non-AKI groups unmatched and 1:1 matched by age,sex,and baseline serum creatinine were separately analyzed.Multivariate logistic and conditional logistic regressions were used to assess the associations between blood glucose variables and AKI.Results:688 consecutively approached patients were included in the final analysis.On multivariate analysis,intra-CPB(adjusted odds ratio[OR]0.802;95%confidence interval[CI],0.706 to 0.912;p=0.001)and post-CPB(adjusted OR 0.830;95%CI,0.744 to 0.925;p=0.001)blood glucose levels were associated with postoperative AKI.There were no significant differences in pre-CPB blood glucose(adjusted OR 0.926;95%CI,0.759 to 1.129;p=0.446)or intraoperative glycemic fluctuations(adjusted OR 0.905;95%CI,0.723 to 1.132;p=0.382)between AKI and Non-AKI groups.Results based on matched cases and controls were consistent with those from the unmatched analyses.Conclusion:Higher intraoperative blood glucose levels during and after CPB were protective factors against postoperative AKI in pediatric patients after congenital heart surgery.
文摘BACKGROUND Patients admitted to intensive care unit(ICU) after cardiac surgery develop acute kidney injury(AKI) immediately post-operation. We hypothesized that AKI occurs mainly due to perioperative risk factors and may affect outcome.AIM To assess peri-operative risk factors for AKI post cardiac surgery and its relationship with clinical outcome.METHODS This was an observational single center, tertiary care setting study, which enrolled 206 consecutive patients, admitted to ICU after cardiac surgery. Patients were followed-up until ICU discharge or death, in order to determine the incidence of AKI, perioperative risk factors for AKI and its association with outcome.Univariate and multivariate logistic regression analysis was performed to assess predictor variables for AKI development.RESULTS After ICU admission, 55 patients(26.7%) developed AKI within 48 h. From the logistic regression analysis performed, high EuroScore Ⅱ(OR: 1.18;95%CI: 1.06-1.31, P = 0.003), white blood cells(WBC) pre-operatively(OR: 1.0;95%CI: 1.0-1.0, P = 0.002) and history of chronic kidney disease(OR: 2.82;95%CI: 1.195-6.65, P = 0.018) emerged as independent predictors of AKI among univariate predictors. AKI that developed AKI had longer duration of mechanical ventilation [1113(777–2195) vs 714(511–1020) min, P = 0.0001] and ICU length of stay [70(28–129) vs 26(21–51) h, P = 0.0001], higher rate of ICU-acquired weakness(16.4% vs 5.3%, P =0.015), reintubation(10.9% vs 1.3%, P = 0.005), dialysis(7% vs 0%, P = 0.005), delirium(36.4% vs 23.8%, P = 0.001) and mortality(3.6% vs 0.7%, P = 0.046).CONCLUSION Patients present frequently with AKI after cardiac surgery. EuroScore Ⅱ, WBC count and chronic kidney disease are independent predictors of AKI development. The occurrence of AKI is associated with poor outcome.
文摘The earliest and most accurate detection of the pathological manifestations of hepatic diseases ensures effective treatments and thus positive prognostic outcomes.In clinical settings,screening and determining the extent of a pathology are prominent factors in preparing remedial agents and administering approp-riate therapeutic procedures.Moreover,in a patient undergoing liver resection,a realistic preoperative simulation of the subject-specific anatomy and physiology also plays a vital part in conducting initial assessments,making surgical decisions during the procedure,and anticipating postoperative results.Conventionally,various medical imaging modalities,e.g.,computed tomography,magnetic resonance imaging,and positron emission tomography,have been employed to assist in these tasks.In fact,several standardized procedures,such as lesion detection and liver segmentation,are also incorporated into prominent commercial software packages.Thus far,most integrated software as a medical device typically involves tedious interactions from the physician,such as manual delineation and empirical adjustments,as per a given patient.With the rapid progress in digital health approaches,especially medical image analysis,a wide range of computer algorithms have been proposed to facilitate those procedures.They include pattern recognition of a liver,its periphery,and lesion,as well as pre-and postoperative simulations.Prior to clinical adoption,however,software must conform to regulatory requirements set by the governing agency,for instance,valid clinical association and analytical and clinical validation.Therefore,this paper provides a detailed account and discussion of the state-of-the-art methods for liver image analyses,visualization,and simulation in the literature.Emphasis is placed upon their concepts,algorithmic classifications,merits,limitations,clinical considerations,and future research trends.
文摘Objective:To explore effective nursing programs for surgical patients with chronic sinusitis(CS).Methods:62 CS surgery patients were randomly divided into a research group and a control group with 31 cases in each group.The patients in the research group received cognitive nursing care,while the patients in the control group received routine nursing care.The nursing effects of the two groups were compared.Results:The postoperative quality-of-life scores,health behavior scores,complication rates,and nursing satisfaction scores of the patients in the research group were all better than those of the control group(P<0.05).Conclusion:The cognitive nursing model significantly improves the condition of CS surgery patients,thus it should be popularized.
文摘Objective: To assess the value of intraoperative ultra-sonography in hepatobiliary surgery.Methods: Aloka-650 and Aloka-500 with a 3.5 MHzprobe were used in preoperative uitrasonography andthose with 5 MHz or 7.5 MHz probes in intraopera-tive ultrasonography. All patients with carcinomawere confirmed pathologically.Results: In 44 patients with liver cancer (76tumors), the diagnostic rate of intraoperative ultra-sonography was 97% (74/76), which was markedlyhigher than 84% (64/76) of preoperative ultra-sonography (P【0.05). The diagnostic rate (92%;22/24) of intraoperative ultrasonography for tumors≤2 cm in diameter was markedly higher than that(54%; 13/24) of preoperative ultrasonography (P【0.01). The diagnostic rate (94%; 16/17) of intra-operative ultrasonography for tumor embulus of thevein was also markedly higher than that (53%; 9/17) of preoperative ultrasonography (P【0.01). Thediagnostic rates of intraoperative and preoperativeultrasonography for cholelithiasis were 99% (108/109) and 97% (106/109) respectively (P】0.05).Yet the diagnostic rate (100%; 12/12) of intraopera-tive ultrasonography for gallbladder carcinoma wasmarkedly higher than that (66.7%; 8/12) of pre-operative ultrasonography (P【0.05). The diagnos-tic rates of intraoperative ultrasonography for chole-docholith and biliary tract cancer were all 100%,markedly higher than those (83%; 20/24 and 75%;12/16) of preoperative ultrasonography (P【0.05).Conclusions: Intraoperative ultrasonography canraise the detective rate of the liver occupying lesionscomparing with that of preoperative untrasonogra-phy. It is of valuable in selecting operative schemeand locating small lesions.
文摘BACKGROUND Enhanced recovery after surgery(ERAS)was introduced in China in 2007.Over time,the scope of ERAS has expanded from abdominal surgery to orthopedics,urology and other fields.Continuous development and research has contributed to progress of ERAS in China.In 2019,to promote the application of ERAS in bone tumor surgery,we formed the“Consensus of Experts on Perioperative Management of Accelerated Rehabilitation in Major Surgery of Bone Tumors in China”.AIM To evaluate the effect of enhanced recovery after bone tumor surgery in perioperative management in China.METHODS One hundred and seven patients who underwent bone tumor surgery at the Second Affiliated Hospital of Xi’an Jiaotong University between May 2019 and April 2021 were randomized into a study group(53 cases)and a control group(54 cases).The study group adopted the ERAS protocol and the control group adopted conventional care.Main outcome measures included postoperative length of stay(LOS),postoperative complications,mortality,and 30-d readmission rates.Secondary outcomes included postoperative visual analog scale(VAS)score of pain,number of blood transfusions,drainage volume in 24 h after operation,patient satisfaction 30 d after discharge,VAS score at 30 d after discharge,and daily standing walking time.RESULTS There were no significant differences in the baseline data,clinical features and surgical site between the two groups.The LOS in the study group with the ERAS protocol was 7.72±3.34 d compared with 10.28±4.27 d in the control group who followed conventional care.The incidence of postoperative nausea and vomiting(PONV)in the study group was 19%and 37%in the control group.The VAS scores of pain on postoperative day 1(POD1)and POD3 in the study group were 4.79±2.34 and 2.79±1.53 compared with 5.28±3.27 and 3.98±2.27 in the control group.The drainage volume in 24 h after the operation was 124.36±23.43 mL in the study group and 167.43±30.87 mL in the control group.The number of blood transfusions in the study group was also lower.The patient satisfaction rate was higher in the study group than in the control group.CONCLUSION The ERAS protocol in the perioperative period of bone tumor surgery can decrease LOS,PONV,and postoperative pain,blood transfusion and 24-h drainage,improve patient satisfaction and accelerate recovery.
文摘Introduction/Purpose: The “transverse abdominal plane block” or TAP block was described by Rafi in 2001. It describes an approach to the neurofascial plane of the transverse abdominal muscle via the Jean-Louis Petit triangle and provides analgesia of the entire homolateral hemi abdomen. The aim of our study was to compare post-operative analgesia and post-operative morphine requirements between transverse abdominal plane block (TAP) and peri-orificial infiltration during laparoscopic abdominal surgery. Material and method: Prospective, randomized study conducted over a 2-year period. The study was conducted in the operating theatre of the Saint Louis Regional Hospital in Senegal. All adult patients undergoing laparoscopic abdominal surgery were included. Clinical aspects, pain scales and morphine consumption were analyzed. Results: A total of 60 patients were enrolled: 30 patients in the TAP group and 30 patients in the infiltration group. The average age was 32.9 years. The indications for laparoscopy were acute appendicitis in 50% of cases, gallbladder stones in 16% and inguinal hernia in 8%. For the TAP group, the mean numerical pain scale was 3.9 at 6 hours post-operatively and 2.1 at 24 hours post-operatively. For the infiltration group, the mean numerical pain scale was 4.3 at 6 hours post-op and 3 at 24 hours post-op. Morphine consumption at 6 hours post-op was on average 0.4 mg/patient for the TAP group and 0.9 mg/patient for the infiltration group. Discussion/conclusion: Analgesia provided by ultrasound-guided TAP block for laparoscopic abdominal surgery appears to be identical to periorificial infiltration. However, the simplicity and reproducibility of ultrasound-guided TAP block gives it a definite advantage.
