The availability of large amounts of medical data from electronic medical records and powerful modern microcomputers enables the development of AI in medicine. AI has proven its applicability in many different medical areas, such as drug discovery, diagnostic radiology and pathology, as well as interventional applications in cardiology and surgery. However, until today, AI is scarcely used in the clinical practice of anesthesiology. Although there has been a significant body of research published on AI applications for anesthesiology in the literature, the number of developed robot systems for commercial use or those ready for clinical trials remains limited. The limitations of AI systems are identified and discussed, which include incorrect medical data formatting, individual patient variability, the lack of ability of current AI systems, anesthesiologist inexperience in AI usage, system unreliability, unexplainable AI conclusions and strict regulations. In order to ensure anesthesiologists’ trust in AI systems and improve their implementation in daily practice, strict quality control of the systems and algorithms should be undertaken. Further, anesthesiology personnel should play an integral role in the development of AI systems before we are able to see more AI integration in clinical anesthesiology.展开更多

Motor vehicle accidents account for almost two-thirds of all maternal non-obstetric, trauma-related deaths, while falls and domestic violence comprise a large percentage of the rest. The leading causes of obstetric trauma are motor vehicle accidents, falls, assaults, and gunshots, and ensuing injuries are classified as blunt abdominal trauma, pelvic fractures, or penetrating trauma . The causes are different with different life styles and different socio-economic and cultural background. Pregnant trauma victims tend to be younger, less severely injured, and more likely African American or of Hispanic descent compared with nonpregnant victims of trauma. Drugs and alcohol are a factor in about 20 percent of maternal trauma. With pregnancy comes the challenge and responsibility of caring for two patients at once, the mother and the fetus. In general, providing optimal maternal care is the best strategy to optimize fetal survival. Decision-making including the condition of the mother, gestational age, status of the fetus, and interventions are based on these key factors. Many providers are involved in the care of the pregnant patient: at the trauma scene, in the emergency department, and in the operating room. The anesthesiologist plays a key role in the care and management of the pregnant trauma patient. All anesthesiologists have ample training in obstetric anesthesia during their residency and frequently cover obstetric units in hospitals where pregnant patients are cared for. On the other hand, most nonobstetric physicians have little obstetric exposure and may be uncomfortable caring for the pregnant patient because of unfamiliarity with the physiologic changes of pregnancy or the evaluation of fetal well-being. This is not only a source of stress for other trauma providers, but can put maternal well-being at risk. Non-obstetric physicians may hesitate to order necessary diagnostic and therapeutic interventions for fear of doing the “wrong thing,” all because the patient is pregnant. A multidisciplinary approach to the pregnant trauma patient involving trauma surgeons, obstetricians, anesthesiologists, emergency medicine, and other providers, is critical to deliver optimal care and achieve the best outcomes for both the mother and the baby. In summary, a multidisciplinary approach to provide optimal maternal care will facilitate to achieve the best outcomes for the mother and is also the best strategy for optimizing fetal survival. The following is a case report of a pregnant trauma patient who needed immediate intervention because of massive placental abruption when only a minimal workup was completed because of the urgency of the situation.展开更多

Low dose naltrexone (LDN) has gained attention in recent years for its potential utility in the management of fibromyalgia, irritable bowel syndrome, multiple sclerosis, and painful diabetic neuropathy. LDN’s analgesic effects have been associated with its ability to increase the production of endorphins while reducing the production of tumor necrosis factor-alpha, interleukin-6, reactive oxygen species and nitric oxide. This meta-analysis aims to systematically review and synthesize the available evidence on efficacy of LDN as an analgesic in pain syndromes, with a focus on chronic (neuro) inflammatory diseases. The goal is to provide clinicians with a more comprehensive estimate of the effectiveness of LDN as a non-opioid option for managing chronic pain and guide future research in the area. Thirteen randomized control trials, published from 1990 to 2022, were selected for the analysis that satisfied inclusion criteria. The overall effects in these studies were calculated using the standardized mean difference (SMD) between the LDN and placebo groups. We found an overall SMD of -10.77 (95% CI: -13.96 to -7.58) with a p-value of 0.002. This indicated that the LDN group experienced a statistically significant reduction in pain compared to placebo. This meta-analysis provides evidence for the potential efficacy of low dose naltrexone in reducing pain and enhancing analgesia in various pain syndromes. LDN may be a useful treatment option for patients suffering from chronic pain, particularly with fibromyalgia, multiple sclerosis, or diabetic neuropathy. However, further research is needed to confirm the efficacy and safety of low dose naltrexone for chronic pain conditions, especially with larger sample sizes, standardized dosing regimens and treatment durations.展开更多

As procedures have become more complex and lengthy, additional medications became essential for adequate sedation. Often time's deep sedation is required for procedures such as endoscopic retrograde cholangiography which necessitates higher doses of narcotics and benzodiazepines or even use of other medications such as ketamine. Given its pharmacologic properties, pro-pofol was rapidly adopted worldwide to gastrointestinal endoscopy for complex procedures and more recently to routine upper and lower endoscopy. Many studies have shown superiority for both the physician and patient compared to standard sedation. Nevertheless, its use remains highly controversial. A number of studies worldwide show that propofol can be given safely by endoscopists or nurses when well trained. Despite this wealth of data, at many centers its use has been pro-hibited unless administered by anesthesiology. In this commentary, we review the use of anesthesia support for endoscopy in the United States based on recent data and its implications for gastroenterologists world-wide.展开更多

Although many medical units in China's cities and rural areas are applying these techniques in operations, it should be pointed out that acupuncture anesthesia is still in the process of development and is of next to no practical and even less scientific value in the western world. However, acupuncture-assisted anesthesia can be useful also in countries other than China.展开更多

文摘Objective: To determine factors influencing anesthesiology choice among resident doctors at the medical school of Marrakech. Materials and Methods: We have conducted a descriptive cross-sectional study based on an anonymous questionnaire. Results: A total of 406/672 questionnaires were returned, with a female/male sex ratio of 1.07. The duration of the training (OR: 3.3;CI 95%: 1.74 - 6.23;p < 0.001), intellectual challenge (OR: 3.02;CI 95%: 1.69 - 5.37;p < 0.001), doctor-patient relationship (OR: 2.22;CI 95%: 1.02 - 4.84;p: 0.04), and financial aspects (OR: 2.14;CI 95%: 1.09 - 4.21;p: 0.02) were independent factors that influenced the choice of anesthesiology. Conclusion: we recommend the succeeding: 1) Support students in their choice;2) Correct misconceptions about certain specialties;3) Promote clinical clerkship;4) Encourage mentorship;5) Increase the salary of at-risk specialties.
文摘BACKGROUND Preoperative anxiety is a common emotional problem during the perioperative period and may adversely affect postoperative recovery.Emergence agitation(EA)is a common complication of general anesthesia that may increase patient discomfort and hospital stay and may be associated with the development of postoperative complications.Pre-anesthetic anxiety may be associated with the development of EA,but studies in this area are lacking.AIM To determine the relationship between pre-anesthetic anxiety and EA after radical surgery in patients with non-small cell lung cancer(NSCLC).METHODS Eighty patients with NSCLC undergoing surgical treatment between June 2020 and June 2023 were conveniently sampled.We used the Hospital Anxiety and Depression Scale’s(HADS)anxiety subscale(HADS-A)to determine patients’anxiety at four time points(T1-T4):Patients’preoperative visit,waiting period in the surgical waiting room,after entering the operating room,and before anesthesia induction,respectively.The Riker Sedation-Agitation Scale(RSAS)examined EA after surgery.Scatter plots of HADS-A and RSAS scores assessed the correlation between patients’pre-anesthesia anxiety status and EA.We performed a partial correlation analysis of HADS-A scores with RSAS scores.RESULTS NSCLC patients’HADS-A scores gradually increased at the four time points:7.33±2.03 at T1,7.99±2.22 at T2,8.05±2.81 at T3,and 8.36±4.17 at T4.The patients’postoperative RSAS score was 4.49±1.18,and 27 patients scored≥5,indicating that 33.75%patients had EA.HADS-A scores at T3 and T4 were significantly higher in patients with EA(9.67±3.02 vs 7.23±2.31,12.56±4.10 vs 6.23±2.05,P<0.001).Scatter plots showed the highest correlation between HADS-A and RSAS scores at T3 and T4.Partial correlation analysis showed a strong positive correlation between HADS-A and RSAS scores at T3 and T4(r=0.296,0.314,P<0.01).CONCLUSION Agitation during anesthesia recovery in patients undergoing radical resection for NSCLC correlated with anxiety at the time of entering the operating room and before anesthesia induction.
文摘Trauma is the leading cause of death for all women of childbearing age. Motor vehicle accidents account for almost two-thirds of all maternal non-obstetric, trauma-related deaths, while falls and domestic violence comprise a large percentage of the rest. The leading causes of obstetric trauma are motor vehicle accidents, falls, assaults, and gunshots, and ensuing injuries are classified as blunt abdominal trauma, pelvic fractures, or penetrating trauma . The causes are different with different life styles and different socio-economic and cultural background. Pregnant trauma victims tend to be younger, less severely injured, and more likely African American or of Hispanic descent compared with nonpregnant victims of trauma. Drugs and alcohol are a factor in about 20 percent of maternal trauma. With pregnancy comes the challenge and responsibility of caring for two patients at once, the mother and the fetus. In general, providing optimal maternal care is the best strategy to optimize fetal survival. Decision-making including the condition of the mother, gestational age, status of the fetus, and interventions are based on these key factors. Many providers are involved in the care of the pregnant patient: at the trauma scene, in the emergency department, and in the operating room. The anesthesiologist plays a key role in the care and management of the pregnant trauma patient. All anesthesiologists have ample training in obstetric anesthesia during their residency and frequently cover obstetric units in hospitals where pregnant patients are cared for. On the other hand, most nonobstetric physicians have little obstetric exposure and may be uncomfortable caring for the pregnant patient because of unfamiliarity with the physiologic changes of pregnancy or the evaluation of fetal well-being. This is not only a source of stress for other trauma providers, but can put maternal well-being at risk. Non-obstetric physicians may hesitate to order necessary diagnostic and therapeutic interventions for fear of doing the “wrong thing,” all because the patient is pregnant. A multidisciplinary approach to the pregnant trauma patient involving trauma surgeons, obstetricians, anesthesiologists, emergency medicine, and other providers, is critical to deliver optimal care and achieve the best outcomes for both the mother and the baby. In summary, a multidisciplinary approach to provide optimal maternal care will facilitate to achieve the best outcomes for the mother and is also the best strategy for optimizing fetal survival. The following is a case report of a pregnant trauma patient who needed immediate intervention because of massive placental abruption when only a minimal workup was completed because of the urgency of the situation.

文摘Artificial intelligence(AI)has long been an attractive topic in medicine,especially in light of the rapid developments in digital and information technologies.AI has already provided some breakthroughs in medicine.With the assistance of AI,more precise models have been used for clinical predictions,diagnoses,and decision-making.This review defines the basic concepts of AI and machine learning(ML),and provides a simple introduction to certain frequently used algorithms in AI and ML.In addition,the review discusses the current common applications of AI and ML in the prediction of anesthesia conditions,including those for preoperative predictions of difficult airways,intraoperative predictions of adverse events and anesthetic effects,and postoperative predictions of vomiting and pain.The use of AI in anesthesiology remains in development,even without extensive promotion and clinical application;moreover,it has immense potential to maintain further development in the future.Finally,the limitations and challenges of AI development for anesthesia are also discussed,along with considerations regarding ethics and safety.
文摘BACKGROUND Functional vocal cord disorders can be a differential diagnosis for postoperative upper airway obstruction requiring urgent intervention.However,this may be unfamiliar to anesthesiologists who would favor inappropriate airway intervention and increased morbidity.CASE SUMMARY A 61-year-old woman underwent cervical laminectomy,followed by laparoscopic cholecystectomy 10 mo later.Despite adequate reversal of neuromuscular blockade,the patient experienced repetitive respiratory difficulty with inspiratory stridor after extubation.After the second operation,the patient was diagnosed with paradoxical vocal fold motion(PVFM)by an otolaryngologist based on the clinical features and fiberoptic bronchoscopy results,and the patient was successfully treated.CONCLUSION PVFM should be considered a differential diagnosis if a patient presents with stridor after general anesthesia.

文摘BACKGROUND Postoperative nausea and vomiting(PONV)are common complications that affect the recovery and well-being of elderly patients undergoing gastrointestinal laparoscopic surgery.AIM To investigate the effect of butorphanol on PONV in this patient population.METHODS A total of 110 elderly patients(≥65 years old)who underwent gastrointestinal laparoscopic surgery were randomly assigned to receive butorphanol(40μg/kg)or sufentanil(0.3μg/kg)during anesthesia induction in a 1:1 ratio.The measured outcomes included the incidence of PONV at 48 h after surgery,intraoperative dose of propofol and remifentanil,Bruggrmann Comfort Scale score in the postanesthesia care unit(PACU),number of compressions for postoperative patientcontrolled intravenous analgesia(PCIA),and time to first flatulence after surgery.RESULTS The results revealed a noteworthy reduction in the occurrence of PONV at 24 h after surgery in the butorphanol group,when compared to the sufentanil group(T1:23.64%vs 5.45%,T2:43.64%vs 20.00%,P<0.05).However,no significant variations were observed between the two groups,in terms of the clinical characteristics,such as the PONV or motion sickness history,intraoperative and postoperative 48-h total infusion volume and hemodynamic parameters,intraoperative dose of propofol and remifentanil,number of postoperative PCIA compressions,time until the first occurrence of postoperative flatulence,and incidence of PONV at 48 h post-surgery(all,P>0.05).Furthermore,patients in the butorphanol group were more comfortable,when compared to patients in the sufentanil group in the PACU.CONCLUSION The present study revealed that butorphanol can be an efficacious substitute for sufentanil during anesthesia induction to diminish PONV within 24 h following gastrointestinal laparoscopic surgery in the elderly,simultaneously improving patient comfort in the PACU.
文摘Chronic pain is a multifaceted debilitating experience often associated with significant physical and emotional burden. Low dose naltrexone (LDN) has gained attention in recent years for its potential utility in the management of fibromyalgia, irritable bowel syndrome, multiple sclerosis, and painful diabetic neuropathy. LDN’s analgesic effects have been associated with its ability to increase the production of endorphins while reducing the production of tumor necrosis factor-alpha, interleukin-6, reactive oxygen species and nitric oxide. This meta-analysis aims to systematically review and synthesize the available evidence on efficacy of LDN as an analgesic in pain syndromes, with a focus on chronic (neuro) inflammatory diseases. The goal is to provide clinicians with a more comprehensive estimate of the effectiveness of LDN as a non-opioid option for managing chronic pain and guide future research in the area. Thirteen randomized control trials, published from 1990 to 2022, were selected for the analysis that satisfied inclusion criteria. The overall effects in these studies were calculated using the standardized mean difference (SMD) between the LDN and placebo groups. We found an overall SMD of -10.77 (95% CI: -13.96 to -7.58) with a p-value of 0.002. This indicated that the LDN group experienced a statistically significant reduction in pain compared to placebo. This meta-analysis provides evidence for the potential efficacy of low dose naltrexone in reducing pain and enhancing analgesia in various pain syndromes. LDN may be a useful treatment option for patients suffering from chronic pain, particularly with fibromyalgia, multiple sclerosis, or diabetic neuropathy. However, further research is needed to confirm the efficacy and safety of low dose naltrexone for chronic pain conditions, especially with larger sample sizes, standardized dosing regimens and treatment durations.
文摘Objectives This study aim to evaluate patient’s perception about anesthesiologists’ job roles and investigate their expectations for anesthesia care.Methods We designed a self-administered questionnaire for this cross-sectional survey study and delivered questionnaire forms to adult in-patients who were scheduled for elective surgery before pre-operative anesthetic visit the day before surgery.We collected information of respondents’ demographic data,education background,health literacy and previous experience of anesthesia,perception of anesthesiologist’s job,the expectation on anesthesia care.Descriptive analyses,χ^2 test and multiple linear regression analysis were used for data analysis.Results Of 550 participants,521(94.7%)completed the questionnaire.In these respondents,335 (64.3%) considered anesthesiology as an independent medical discipline,225 (43.2%) believed that anesthesiology department was an independent clinical department,and 243 (46.6%) recognized anesthesiologists as qualified doctors.Only 21.5% of them knew that anesthesiologists also work in the intensive care unit and 26.9% of them knew that anesthesiologists also work in pain clinic as well.Younger patients (β=-0.044,P<0.001),those with higher education (β=1.200,P<0.001),or with better health literacy (β=0.781,P=0.005) had significant more knowledge about the job roles of anesthesiologists.Most patients demanded pre-anesthetic visit (80.5%),expected availability of preoperative anesthetic clinic (74.1%),wished to receive more information about anesthesia (91.3%) and anesthesiologist (77.4%).Conclusions Patients’ perception about anesthesiologists might be limited.Efforts should be made on education about anesthesia,especially for elderly patients and those under-educated patients.Preoperative anesthetic clinic is expected by most in-patients.
文摘Conscious sedation has been the standard of care for many years for gastrointestinal endoscopic procedures. As procedures have become more complex and lengthy, additional medications became essential for adequate sedation. Often time's deep sedation is required for procedures such as endoscopic retrograde cholangiography which necessitates higher doses of narcotics and benzodiazepines or even use of other medications such as ketamine. Given its pharmacologic properties, pro-pofol was rapidly adopted worldwide to gastrointestinal endoscopy for complex procedures and more recently to routine upper and lower endoscopy. Many studies have shown superiority for both the physician and patient compared to standard sedation. Nevertheless, its use remains highly controversial. A number of studies worldwide show that propofol can be given safely by endoscopists or nurses when well trained. Despite this wealth of data, at many centers its use has been pro-hibited unless administered by anesthesiology. In this commentary, we review the use of anesthesia support for endoscopy in the United States based on recent data and its implications for gastroenterologists world-wide.

文摘BACKGROUND Wavelet index(WLi)and pain rating index(PRi)are new parameters for regulating general anesthesia depth based on wavelet analysis.AIM To investigate the safety and efficacy of using WLi or PRi in sevoflurane anesthesia.METHODS This randomized controlled trial enrolled 66 patients scheduled for elective posterior lumbar interbody fusion surgery under sevoflurane anesthesia between September 2017 and February 2018.A random number generator was used to assign the eligible patients to three groups:Systolic blood pressure(SBP)monitoring group,WLi monitoring group,and PRi monitoring group.The main anesthesiologist was aware of the patient grouping and intervention used.The primary endpoint was anesthesia recovery time.Secondary endpoints included extubation time,sevoflurane consumption,number of unwanted events/interventions,number of adverse events and postoperative visual analogue scale for pain.RESULTS A total of 62 patients were included in the final analysis(SBP group,n=21;WLi group,n=21;and PRi group,n=20).There were no significant differences among the three groups in patient age,gender distribution,body mass index,American Society of Anesthesiologists class,duration of surgery,or duration of anesthesia.Anesthesia recovery time was shorter in the WLi and PRi groups than in the SBP group with no significant difference between the WLi and PRi groups.Extubation time was shorter in the WLi and PRi groups than in the SBP group.Sevoflurane consumption was lower in the WLi and PRi groups than in the SBP group.Nicardipine was more commonly needed to treat hypertension in the WLi and PRi groups than in the SBP group.CONCLUSION Regulation of sevoflurane anesthesia depth with WLi or PRi reduced anesthesia recovery time,extubation time and sevoflurane consumption without intraoperative unwanted events.
文摘Glucose control in patient admitted to the intensive care unit has been a topic of much debate over the past 20 years.The harmful effects of uncontrolled hyperglycemia and hypoglycemia in critically ill patients is well established.Although a large clinical trial in 2001 demonstrated significant mortality and morbidity benefits with tight glucose control in this patient population,the results could not be replicated by other investigators.The“Normoglycemia in Intensive Care Evaluation-Survival Using Glucose Algorithm Regulation”trial in 2009 established that tight glucose control was not only of no benefit,but in fact harmful due to the significant risk of hypoglycemia.The current guidelines suggest a moderate approach with the initiation of intravenous insulin therapy in critically ill patients when the blood glucose level is above 180 mg/dL.The most important factor that underpins glycemic management in intensive care unit patients is the consequent prevention of hypoglycemia.Robust glucose monitoring strategies and insulin protocols need to be implemented in order to achieve this goal.

文摘Using acupuncture instead of anesthetics to induce analgesia was performed in China many years ago in surgical anesthetization. Although many medical units in China's cities and rural areas are applying these techniques in operations, it should be pointed out that acupuncture anesthesia is still in the process of development and is of next to no practical and even less scientific value in the western world. However, acupuncture-assisted anesthesia can be useful also in countries other than China.

文摘Currently,no reported studies have evaluated intraoperative handover among anesthesia providers.Studies on anesthetic handover in the US recovery room setting observed that handover processes are insufficient and,in many instances,significant intraoperative events are disregarded.An online survey tool was sent to anesthesia providers at US anesthesia residency programs nationwide（120 out of the 132 US programs encompassing around 4500 residents and their academic MDAs） and a smaller survey selection of CRNAs（10 institutions about 300 CRNAs in the metropolitan area of Detroit,MI,USA） to collect information on handover practices.The response rate to this survey（n=216） was comprised of approximately 5%（n = 71） of the resident population in US anesthesia programs,5%（n=87） of MDAs,and 20%（n=58） of the CRNAs.Out of all respondents（n=212）,49.1%had no hand-over protocol at their institution and 88%of respondents who did have institutional handover protocols believed them insufficient for effective patient handover.In addiiton,84.8%of all responders reported situations where there was insufficient information received during a patient handover.Only 7%of the respondents reported never experiencing complications or mismanagement due to poor or incomplete hand-overs.In contrast,60%reported rarely having complications,31%reported sometimes having complications,and 3%reported frequent complications.In conclusion,handover transition of patient care is a vulnerable and potentially life-threatening event in the operating room.Our preliminary study suggests that current intraoperatvive handover practices among anesthesia providers are suboptimal and that national patient handover guidelines are required to improve patient safety.
