The efficacy of acupressure at the P6 point in the prevention of nausea and vomiting during and after Caesarean section was studied. A double-blind, randomized controlled study of acupressure vs placebo was designed. Ninety-four patients scheduled for Caesarean section were included. The anaesthetic technique and postoperative analgesia were standardized. The use of acupressure reduced the incidence of nausea or vomiting from 53% to 23% compared with placebo (95% confidence interval (CI) 0.34-0.25; P = 0.002) during the operation and from 66% to 36% compared with placebo (95% CI 0.34-0.19; P = 0.003) after the operation. Other variables were similar between the groups.
研究了剖宫产术中及术后在P6穴位进行指压预防恶心和呕吐的疗效。设计了一项指压与安慰剂对照的双盲随机对照研究。纳入了94例计划行剖宫产的患者。麻醉技术和术后镇痛均标准化。与安慰剂相比，指压可使术中恶心或呕吐的发生率从53%降至23%（95%置信区间（CI）0.34 - 0.25；P = 0.002），术后从66%降至36%（95% CI 0.34 - 0.19；P = 0.003）。两组间其他变量相似。
