Enhanced recovery after surgery (ERAS) is a protocol designed to improve perioperative outcomes by multidisciplinary team with evidence-based interventions. The implementation of ERAS concept has been proved to reduce postoperative complications and hospital stay. The anesthesia management under the concept of ERAS is the basis of safe and smooth ambulatory surgical protocol. This article summarizes the latest clinical evidence at home and abroad, and reviews the preoperative optimization, anesthesia mode selection, ventilation strategies, fluid management, temperature support, pain management, postoperative nausea and vomiting prevention, postoperative nutritional support, and postoperative sleep improvement in the management of anesthesia under ERAS concept, in order to provide a reference for anesthesia management in ambulatory surgery.
ObjectiveTo systematically review the effect of dexamethasone in preventing post-operative nausea and vomiting (PONV) associated with epidural opioids for post-cesarean section analgesia. MethodsWe searched PubMed, EMbase, CNKI, WanFang Data and CBM databases from inception to Dec. 31th 2015, to collect randomized controlled trials (RCTs) comparing dexamethasone with placebo/blank for the prevention of PONV associated with epidural opioids for postcesarean section analgesia. Two reviewer independently screened literature, extracted data, and assess the risk of bias of included studies. Then, meta-analysis was conducted by using RevMan 5.3 software. ResultsA total of 11 RCTs from 10 papers involving 1 011 patients were included. The results of meta-analysis showed that, compared with the placebo/ blank group, the dexamethasone group had lower incidence rates of post-operative nausea (RR=0.50, 95% CI 0.39 to 0.65, P < 0.000 01), postoperative vomiting (RR=0.39, 95% CI 0.29 to 0.52, P < 0.000 01), PONV (RR=0.37, 95% CI 0.30 to 0.46, P < 0.000 01), and rescue antiemetic (RR=0.34, 95% CI 0.19 to 0.62, P=0.000 5). ConclusionsCurrent evidence indicates that dexamethasone is effective for preventing PONV after epidural opioids for post-cesarean section analgesia. Due to the limited quantity and quality of the included studies, the above conclusion needs to be further verified by more high quality studies.
Objective To evaluate the safety and necessity of shortening the time of preoperative fasting and fluid limitation in lumber disc herniation patients undergoing minimally invasive surgery. Methods A total of 141 eligible patients were assigned into the control group (n=70) and the intervention group (n=71) between April and September 2015. The control group received traditional fasting method while the intervention group received new preoperative fasting method. The time of fasting food and fluid limitation, the incidences of hunger, thirsty, aspiration, postoperative nausea and vomiting, postoperative abdominal distension, and length of stay and the subjective feeling in hospital were compared between the two groups. Results The average time of preoperative fasting and fluid limitation were (13.09±2.30) and (7.84±2.10) hours in the control group and (6.88±0.96) and (4.68±1.08) hours in the intervention group. The incidence of thirsty in the intervention group was shorter than that in the control group, and the subjective feeling in hospital of the intervention group was better than that in the control group (P<0.05). There were no significant differences in the incidence of postoperative nausea and vomiting, the incidence of postoperative abdominal distension, and length of hospital stay between the two groups (P>0.05). Conclusions Shortening the time of preoperative fasting and fluid limitation can improve the subjective feeling in hospital of lumber disc herniation patients undergoing minimally invasive surgery, not increasing the incidences of complications. It can be applied gradually.
Objective?To evaluate the efficacy and safety of 5 HT-3 receptor inhibitor tropisetron injected in the postoperative nausea and vomiting (PONV) after general anesthesia. Methods?We searched the PubMed, EBSCO, Springer, Ovid, and CNKI to identify randomized controlled trials (RCTs) about tropisetron in preventing PONV after general anesthesia from January 1995 to September 2009. We also consulted references of the included studies for omission. The methodological quality of the included RCTs was assessed and data were extracted according to the standard of the Cochrane Handbook 5.0.1. The meta-analyses were performed by RevMan 4.2.10 software. Results?A total of 17 RCTs involving 4 678 patients were included. The results of meta-analyses showed that: (1) Efficacy: tropisetron injected could decrease the incidence of PONV after general anesthesia (RR=0.41, 95%CI 0.29 to 0.60), and decrease the incidence of PONV after general anesthesia with opioid drugs in patient controlled analgesia (RR=0.30, 95%CI 0.15 to 0.60); tropistron injected once or more could decrease the incidence of PONV in combination of PCA with tramadol (RR=0.41, 95%CI 0.29 to 0.56; RR=0.10, 95%CI 0.06 to 0.19); and tropisetron combined with dexamethasome could also lessen the incidence of PONV (RR=0.27, 95%CI 0.13 to 0.57). (2) Safety: Tropisetron injected could lessen the incidence of postoperative headache and dizziness (RR=0.35, 95%CI 0.16 to 0.75), but could not significantly decrease the pruritus and somnolence. Conclusion?Tropisetron injected can significantly decrease the incidence of PONV after general anesthesia, and it will not increase the adverse effect and the incidence of postoperative complications. Furthermore, it has also the advantage of decreasing postoperative headache and dizziness.
Objective To explore whether bundled care for anesthesia management can reduce the risk of postoperative nausea and vomiting (PONV). Methods The data of laparoscopic cholecystectomy patients admitted to the Day Surgery Center of West China Hospital, Sichuan University between July and November 2021 were retrospectively collected. Patients were divided into a bundled care group and a control group based on whether anesthesia management was implemented according to the bundled care. The demographic characteristics, intraoperative anesthesia management methods, postoperative conditions, and incidence of PONV between the two groups of patients were analyzed and compared. Results A total of 314 patients were included. Among them, there were 124 cases in the bundled care group and 190 cases in the control group; PONV occurred in 52 cases, the incidence of PONV was 16.6% (52/314). Except for surgical time and postoperative incision infiltration (P>0.05), there were statistically significant differences in age, gender, body mass index, anesthesia time, airway establishment, and postoperative analgesic use between the two groups of patients (P<0.05). There was no statistically significant difference in the occurrence of PONV between the bundled care group and the control group (17 vs. 35 cases; χ2=1.205, P>0.05). The results of logistic regression analysis showed that PONV was correlated with gender [odds ratio=0.107, 95% confidence interval (0.030, 0.375), P<0.001], and using bundled care [odds ratio=0.388, 95% confidence interval (0.169, 0.894), P=0.026]. Conclusions Women are at high risk of PONV among patients undergoing day laparoscopic cholecystectomy. The risk of PONV is lower when using bundled care.
目的 探讨针刺治疗在防治术后恶心呕吐（PONV）中的作用与疗效。 方法 通过对2012年6月收治的1例全身麻醉下行小脑血肿清除术后出现持续性恶心呕吐症状，后辅以针刺治疗好转的病例报道，就针刺治疗对PONV的穴位选择，刺激方式，介入时间等相关研究进行复习和总结。 结果 患者恶心呕吐症状在选取中脘、足三里（双）、内关（双）穴针刺治疗3次后（30 min/次）明显减少，自诉恶心程度较前缓解，连续针灸6次后呕吐现象得到有效控制。 结论 目前有关针刺治疗PONV的研究越来越多，但尚无统一的治疗标准。
目的 探讨腹腔镜胆囊切除术（laparoscopic cholecystectomy，LC）中不同CO2气腹压力对患者肝功能、动脉血气及对颈、肩痛的影响。方法 选择行择期LC术患者120例，采用随机数字表法，按住院先后顺序对应入组，随机均分为气腹压力10mmHg （1 mm Hg=0.133kPa）组、12mmHg组及14mmHg组3组；对比分析3组患者手术后肝功能、血气指标以及术后当天、第1和第2天恶心、呕吐及颈肩部疼痛的发生率。结果 3组患者术前各参数组间比较差异均无统计学意义（P＞0.05）。术后肝功能及血气分析指标的改变3组间的差异有统计学意义（P＜0.05），气腹压力越大，其术后AST、ALT及TBIL水平升高越明显，而pH及PO2的下降越明显，PCO2的升高也越明显；术后患者颈、肩痛及恶心呕吐发生率3组间比较差异也有统计学意义（P＜0.05），气腹压力越大，术后颈、肩痛及恶心呕吐发生率越高。结论 CO2气腹压力对术后肝功能及动脉血气指标的改变以及术后颈、肩痛和恶心呕吐发生率有明显影响。
Objective To investigate the patient’s psychological anticipation and occurrence of chemotherapy-induced nausea and vomiting (CINV), and to assess the influence of CINV on quality of life, so as to provide evidence for clinical doctors to recognize and pay attention to CINV. Methods The patients in the Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology who took either moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC) were randomly sampled with a questionnaire for two circles. Patients were asked to record the following indexes before chemotherapy, on the second day and the sixth day of chemotherapy: acute and delayed nausea and vomiting, independently taking antiemetics, and functional living index-emesis (FLIE). Then, descriptive analysis and multiple linear regression analysis were adopted for the outcomes of investigation. Results A total of 344 patients were investigated, of which 303 fulfilled the questionnaire finally. For the single-day chemotherapy, the acute nausea and vomiting, delayed nausea vomiting and overall complete remission in the MEC group were 86.1%, 76.6%, and 71.5%, respectively; while those of the HEC group were 84.1%, 71.0%, and 66.7%, respectively. For the multi-day chemotherapy, the acute nausea and vomiting, delayed nausea vomiting and overall complete remission were 93.8%, 64.9%, and 64.9%, respectively. Patients’ expectation of nausea and anticipatory anxiety was closely related to the delayed nausea in their prior circle of chemotherapy. Based on the FLIE assessment, about 30% of all patients reported reduced daily living function. Conclusion CINV remains a significant problem among patients in China, especially in controlling the reaction during delayed phase and nausea as well. It requires that more attention should be paid to CINV and more effective prophylaxis should be adopted in clinical practice.
