To evaluate the effectiveness of acupressure applied at meridian P6 point for prevention of nausea and vomiting in patients undergoing laparoscopic cholecystectomy.
A randomized double blind study was performed in 50 ASA I and II patients scheduled for laparoscopic cholecystectomy. Patients were divided into two groups; control and placebo. In the control group acupressure was applied at P6 point half an hour before surgery while in the placebo group the acupressure band was tied on meridian P6 point but the plastic bead was placed on the dosum of right forearm away from meridian P6 point. Patients were assessed for nausea and vomiting for six hours after surgery. Anaesthetic technique and postoperative analgesia were standardized for all patients.
Results showed that the incidence of postoperative nausea and vomiting was 36% in the treatment group and 40% in placebo group, which is statistically insignificant.
Application of acupressure at P6 point half an hour before induction of anaesthesia does not significantly alter the incidence of postoperative nausea and/or vomiting within 6 hours after surgery.
评估在经络P6点进行指压对预防腹腔镜胆囊切除术患者恶心呕吐的效果。
对50例计划行腹腔镜胆囊切除术的ASA I级和II级患者进行随机双盲研究。患者分为两组：对照组和安慰剂组。对照组在手术前半小时在P6点进行指压，而在安慰剂组，指压带系在经络P6点，但塑料珠放置在右前臂尺侧，远离经络P6点。术后6小时对患者的恶心呕吐情况进行评估。所有患者的麻醉技术和术后镇痛均标准化。
结果显示，治疗组术后恶心呕吐发生率为36%，安慰剂组为40%，差异无统计学意义。
麻醉诱导前半小时在P6点进行指压，并不会显著改变术后6小时内恶心和/或呕吐的发生率。
