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.
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。
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.
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.
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.
ObjectiveTo compare the postoperative nausea and vomiting (PONV) after laparoscopic sleeve gastrectomy (LSG) and single-anastomosis sleeve ileal bypass (SASI), and to explore the risk factors for PONV. MethodA total of 220 patients at the Affiliated Hospital of Xuzhou Medical University from June 2022 to December 2022 were prospectively collected, and were randomly divided into the LSG group and the SASI group; the general condition of the patients was recorded. PONV was assessed on the POD0, POD1, POD2, POD30, POD60, POD90, using the Rhodes index score.ResultsThe total Rhodes index score in the LSG group was higher than that in the SASI group [(25.56±13.54) vs. (16.06±11.28), P<0.05]. The results of multiple linear regression analysis showed that female (P=0.014), LSG (P<0.001), young age (P=0.050), and low BMI (P=0.019) were risk factors for PONV. ConclusionsCompared with LSG, the Rhodes index score after SASI is low. For young women with low BMI, special attention should be paid to the prevention and treatment of PONV after LSG.
