Methods: One hundred and seventy-eight patients, who had received intravenous patient-controlled analgesia (PCA) with Fentanyl, were assigned randomly to three groups using random numbers: a pre-operative EA group (PrEA), a post-operative EA group (PoEA), and a non-acupuncture control group (NC). An anesthetist evaluated the incidence and severity of nausea and vomiting for 48 h after surgery blindly. The main outcomes were severity and freguency of PONV, which were measured with a self-reported questionnaire and a confirmation from the anesthetist. The data were analyzed with ANOVA and Z-test. Results: The incidence of nausea and vomiting was significantly lower in the PrEA group than the NC group during 48 h after surgery (P〈0.01, P〈0.05). The incidence of vomiting was also significantly lower in the PrEA group than the PoEA group (P〈0.05). The PoEA subjects evidenced no significant differences compared with the NC subjects in terms of the incidence of nausea and vomiting (P〈0.05). The severity of nausea was significantly lower in the PrEA group than in the NC and PoEA groups (P〈0.05). Conclusions: EA on PC6 is effective in the prevention of PONV, and pre-operative acupuncture is more effective than post-operative acupuncture.展开更多

Methods: Ninety-six ASA Grade Ⅰ-Ⅱ patients scheduled for laparoscopic cholecystectomy were randomized into Neiguan (P6) electroacupoint stimulation group (treated group) and a placebo control group (placement of electrodes without electroacupoint stimulation). The anesthetic regimen was standardized by needling at Neiguan on the left side and connecting the TOF peripheral nerve stimulator. The incidence of nausea, vomiting, severity, antiemetic dosage and the degree of pain were assessed at 0, 60, 120 min, and 24 h after surgery. Results: The incidence of nausea and vomiting, the dose of antiemetics and the occurrence of severe nausea were all significantly lower in the treated group compared with the control group and the score for pain was obviously reduced in patients of the treated group at 24 h post-operation (P〈0.05 or P〈0.01). Conclusion: Transcutaneous electroacupoint stimulation at P6 with the TOF mode could reduce the incidence and severity of nausea and vomiting with analgesic effects.展开更多

文摘BACKGROUND Rehabilitation of elderly patients with a high body mass index(BMI)after cholecystectomy carries risks and requires the adoption of effective perioperative management strategies.The enhanced recovery after surgery(ERAS)protocol is a comprehensive treatment approach that facilitates early patient recovery and reduces postoperative complications.AIM To compare the effectiveness of traditional perioperative management methods with the ERAS protocol in elderly patients with gallbladder stones and a high BMI.METHODS This retrospective cohort study examined data from 198 elderly patients with a high BMI who underwent cholecystectomy at the Shanghai Fourth People's Hospital from August 2019 to August 2022.Among them,99 patients were managed using the traditional perioperative care approach(non-ERAS protocol),while the remaining 99 patients were managed using the ERAS protocol.Relevant indicator data were collected for patients preoperatively,intraoperatively,and postoperatively,and surgical outcomes were compared between the two groups.RESULTS The comparison results between the two groups of patients in terms of age,sex,BMI,underlying diseases,surgical type,and preoperative hospital stay showed no statistically significant differences.However,the ERAS group had a significantly shorter preoperative fasting time than the non-ERAS group(4.0±0.9 h vs 7.6±0.9 h).Regarding intraoperative indicators,there were no significant differences between the two groups of patients.However,in terms of postoperative recovery,the ERAS protocol group exhibited significant advantages over the non-ERAS group,including a shorter hospital stay,lower postoperative pain scores and postoperative hunger scores,and higher satisfaction levels.The readmission rate was lower in the ERAS protocol group than in the non-ERAS group(3.0%vs 8.1%),although the difference was not significant.Furthermore,there were significant differences between the two groups in terms of postoperative nausea and vomiting severity,postoperative abdominal distention at 24 h,and daily life ability scores.CONCLUSION The findings of this study demonstrate that the ERAS protocol confers significant advantages in postoperative outcomes following cholecystectomy,including reduced readmission rates,decreased postoperative nausea and vomiting,alleviated abdominal distension,and enhanced functional capacity.While the protocol may not exhibit significant improvement in early postoperative symptoms,it does exhibit advantages in long-term postoperative symptoms and recovery.These findings underscore the importance of implementing the ERAS protocol in the postoperative management of cholecystectomy patients,as it contributes to improving patients'recovery and quality of life while reducing health care resource utilization.
文摘Objective: To investigate the treatment time dependence of electroacupuncture (EA) on Neiguan (PC6) for preventing postoperative nausea and vomiting (PONV). Methods: One hundred and seventy-eight patients, who had received intravenous patient-controlled analgesia (PCA) with Fentanyl, were assigned randomly to three groups using random numbers: a pre-operative EA group (PrEA), a post-operative EA group (PoEA), and a non-acupuncture control group (NC). An anesthetist evaluated the incidence and severity of nausea and vomiting for 48 h after surgery blindly. The main outcomes were severity and freguency of PONV, which were measured with a self-reported questionnaire and a confirmation from the anesthetist. The data were analyzed with ANOVA and Z-test. Results: The incidence of nausea and vomiting was significantly lower in the PrEA group than the NC group during 48 h after surgery (P〈0.01, P〈0.05). The incidence of vomiting was also significantly lower in the PrEA group than the PoEA group (P〈0.05). The PoEA subjects evidenced no significant differences compared with the NC subjects in terms of the incidence of nausea and vomiting (P〈0.05). The severity of nausea was significantly lower in the PrEA group than in the NC and PoEA groups (P〈0.05). Conclusions: EA on PC6 is effective in the prevention of PONV, and pre-operative acupuncture is more effective than post-operative acupuncture.
文摘Objective: To evaluate the efficacy of transcutaneous electroacupoint stimulation with a train-of-four (TOF) mode for the prevention of postoperative nausea and vomiting (PONV) in the patients undergoing laparoscopic cholecystectomy. Methods: Ninety-six ASA Grade Ⅰ-Ⅱ patients scheduled for laparoscopic cholecystectomy were randomized into Neiguan (P6) electroacupoint stimulation group (treated group) and a placebo control group (placement of electrodes without electroacupoint stimulation). The anesthetic regimen was standardized by needling at Neiguan on the left side and connecting the TOF peripheral nerve stimulator. The incidence of nausea, vomiting, severity, antiemetic dosage and the degree of pain were assessed at 0, 60, 120 min, and 24 h after surgery. Results: The incidence of nausea and vomiting, the dose of antiemetics and the occurrence of severe nausea were all significantly lower in the treated group compared with the control group and the score for pain was obviously reduced in patients of the treated group at 24 h post-operation (P〈0.05 or P〈0.01). Conclusion: Transcutaneous electroacupoint stimulation at P6 with the TOF mode could reduce the incidence and severity of nausea and vomiting with analgesic effects.
