Abstract

Objective: To evaluate the efficacy of different periods for the prevention of postoperative nausea and vomiting (PONV) in patients undergoing gynecological laparoscopy with transcutaneous electrical acupoint stimulation (TEAS).

Design: Prospective, randomized, double-blind trial.

Setting: An academic medical canter specializing in the care of women and children.

Population or sample: A total of 120 women were enrolled.

Methods: Patients were randomly allocated to three groups: a single-period TEAS group (Group S, n = 40), a multi-period TEAS group (Group M, n = 40) and a non-stimulation control group (Group C, n = 40). TEAS was applied at specific acupuncture points preoperatively and postoperatively.

Main outcome measures: The primary outcome was the incidence and severity of PONV during the 48 h after surgery and the secondary outcomes included pain, early recovery after surgery, and complication.

Results: Within postoperative 0-2 h, 4-12 h, group M had less frequency and lower scores for nausea compared with group C and group S had only less frequency of nausea compared with group C at 4-12 h postoperatively. The frequency and severity of vomiting for group M were less than group S in the postoperative 2-4 h. Group M mitigated pain and reduced the rescue antiemetic compared to group S.

Conclusion: Multiple-period TEAS provides greater efficacy and a longer duration of action than single-period TEAS. It effectively reduces PONV in patients undergoing gynecological laparoscopic surgery which could be a new option in multimodal prophylactic antiemetic regimes for perioperative undergoing gynecological laparoscopic surgery.

单次或多次经皮穴位电刺激对妇科腹腔镜手术患者术后恶心和呕吐的影响：一项前瞻性随机双盲试验

目的：探讨不同时期预防妇科腹腔镜经皮穴位电刺激术后恶心呕吐（PONV）的效果。设计：前瞻性、随机、双盲试验。环境：一个专门照顾妇女和儿童的学术医疗中心。总体或样本：共纳入120名妇女。方法：将患者随机分为3组：单期tea组（S组，n = 40）、多期tea组（M组，n = 40）和非刺激对照组（C组，n = 40）。术前和术后在特定穴位应用TEAS。主要观察指标：主要观察指标为术后48 h内PONV的发生率和严重程度，次要观察指标为疼痛、术后早期恢复、并发症。结果：术后0 ~ 2 h、4 ~ 12 h， M组恶心发生率和评分均低于C组；术后4 ~ 12 h， S组恶心发生率仅低于C组。术后2 ~ 4 h， M组呕吐频次及严重程度均低于S组。与S组相比，M组减轻了疼痛，减少了抢救止吐药的使用。结论：多期tea比单期tea疗效更好，作用时间更长。可有效降低妇科腹腔镜手术患者的PONV，为妇科腹腔镜手术围手术期多模式预防止吐方案提供新的选择。试验注册：中国临床试验注册中心ChiCTR2200065802，注册日期15/11/2022。https / / www.chictr.org.cn/bin/project/edit吗?pid = 175377。
