针刺内关穴对开颅术后恶心呕吐预防作用的随机对照研究

目的:探讨针刺内关穴对开颅术后恶心呕吐的预防与治疗作用。方法:将60例拟行择期开颅手术的患者随机分为针刺组30例及对照组30例。针刺组在由手术间转至苏醒室后,即刻针刺内关穴,留针20min后起针,其间行针1次。观察两组患者术后2、6、24h发生事实呕吐的人数,比较两组恶心程度评分。结果:针刺组各时段术后呕吐发生人数及恶心程度评分均较对照组低(P<0.05)。结论:针刺内关穴对开颅术后恶心呕吐具有预防与治疗作用。

A Randomized Controlled Clinical Trial for Acupuncture Stimulation of Neiguan (PC 6) to Prevent Postoperative Nausea and Vomiting

Objective To observe whether acupuncture stimulation of Neiguan(PC 6) can prevent postoperative nausea and vomiting(PONV) in patients undergoing craniotomy.Methods A total of 60 patients scheduled for craniotomy were randomly assigned to acupuncture group(n=30) and control group(n=30).When regaining consciousness from the surgical anesthesia,patients of the acupuncture group received immediate acupuncture stimulation of bilateral Neiguan(PC 6).After insertion,the filiform needles were manipulated with uniform reinforcing-reducing method for about 1 min(re-manipulated once again 10 min later),followed by retaining it for 20 min.Patients of the control group received no treatment.Vomiting or retching(having vomitus) was considered as an emetic episode.Nausea was assessed by a four-point verbal rating scale(none,mild,moderate,severe).Results Following the treatment,in the acupuncture group,1 patient had a vomiting from 0 to 2 h,and 1 patient had a vomiting from 2 to 6 h after the operation,and no patients had this symptom 6 h after the operation.While in the control group,the vomiting occurred in 11 patients from 0 to 2 h,8 cases from 2 to 6 h,and other 8 cases from 6 to 24 h after the operation.Comparison between two groups showed that the nausea scores in the 3 time-stages were significantly lower in the acupuncture group than in the control group(P<0.05).Conclusion Acupuncture stimulation of PC 6 is effective in preventing and treating PONV in patients undergonig craniotomy.
