Acupressure PONV

<b>Efficacy of p6 acupressure band for prevention of postoperative nausea and vomiting in children: A randomized controlled trial</b><b>Abstract</b><b>Introduction</b>Postoperative nausea and vomiting in children remain a significant problem. Acupressure to P6 acupoint has been one of the effective strategies in the management of nausea and vomiting in the adult population. The aim of this study is to assess the effectiveness of P6 acupressure band in prevention of PONV in children.<b>Methods</b>This prospective randomized controlled trial recruited children who underwent elective surgery in a tertiary university hospital. Patients were randomised into 2 groups, Group 1 received acupressure band and group 2 received a standard elastic band 30 minutes prior to induction of anaesthesia. The acupressure band was worn with its embedded bead placed at P6 acupoint. All patients received standard care of anaesthesia. Occurrence of nausea and vomiting post-surgery were recorded hourly until 24 hours and band were removed after 24hours.<b>Results</b>Sixty four patients were recruited. Median Eberhart PONV risk score of 2 in both groups corresponded to a 20% risk of PONV. Duration of surgery and opioid requirement intraoperatively were comparable between the two groups. Both groups did not show a significant difference in occurrence of PONV and the requirement of rescue antiemetics postoperatively. Parental satisfaction on management of PONV in Group 1 and 2 were achieved at 89.4% and 94.2% respectively.<b>Conclusion</b>Acupressure band at p6 acupoint is not superior to placebo in management of PONV in children.

<b>P6穴位按压带预防儿童术后恶心呕吐的疗效：一项随机对照试验</b><b>摘要</b><b>引言</b>儿童术后恶心呕吐（Postoperative Nausea and Vomiting, PONV）仍是一个重要问题。P6穴位按压已成为成人恶心呕吐管理的有效策略之一。本研究旨在评估P6穴位按压带预防儿童PONV的有效性。<b>方法</b>这项前瞻性随机对照试验招募了在某三级大学医院接受择期手术的儿童。患者被随机分为两组：1组在麻醉诱导前30分钟佩戴穴位按压带，2组佩戴标准弹性带。穴位按压带的内嵌珠子置于P6穴位处。所有患者均接受标准麻醉护理。术后每小时记录恶心呕吐发生情况直至24小时，24小时后移除按压带。<b>结果</b>共招募64例患者。两组的Eberhart PONV风险评分中位数均为2，对应20%的PONV发生风险。两组的手术持续时间和术中阿片类药物需求量具有可比性。两组在PONV发生率及术后抢救性止吐药（rescue antiemetics）的需求方面无显著差异。1组和2组家长对PONV管理的满意度分别为89.4%和94.2%。<b>结论</b>P6穴位按压带在儿童PONV管理中并不优于安慰剂。
