目的:观察电针刺激内麻点用于腹部手术后镇痛的有效性及安全性.方法:选取120例行腹部手术的患者,随机分为针刺组(60例)和药物组(60例).针刺组给予电针刺激内麻点(位于小腿的内侧,内踝上7寸,胫骨后缘约0.5寸处)治疗,药物组给予舒芬太尼患者静脉自控镇痛(PCIA)治疗.治疗后比较两组患者视觉模拟量表评分( VAS)、安全性、镇痛效果及血浆β-内啡肽含量.结果:两组术后2、4、8、16、24、48 h各时点VAS评分比较,针刺组评分均低于药物组(均P＜0.05)；两组术后2、4、16、24 h各时点镇痛疗效比较,针刺组均优于药物组( P＜0.05,P＜0.01)；两组患者术后即刻、8、16、48 h各时点β-内啡肽含量较治疗前都有增高(均P＜0.05),针刺组较药物组增加更明显(均P＜0.05).针刺组术后安全等级高于药物组(P＜0.05),其中针刺组有2例患者因惧怕针刺而停止治疗,药物组共有24例出现不良反应,3例因恶心、呕吐等不良反应而中止治疗.结论:电针刺激内麻点用于腹部手术后镇痛效果及安全性均优于舒芬太尼静脉自控镇痛.“,”Objective To observe the analgesia effectiveness and safety of electroacupuncture at Nèimádiǎn (内麻点 Extra) after abdominal surgery.Methods One hundred and twenty patients with routine abdominal surgery were randomly divided into an acupuncture group and a medication group,60 cases in each group.The acupuncture group was treated with electroacupuncture at Nèimádiǎn(内麻点 Extra),which was located on the medial side of lower leg,7 cun above the medial malleolus and about 0.5 cun from post edge of tibia.The medication group was treated with patient-controlled intravenous analgesia (PCIA) with Sufentanil.Mter the treatment,the Visual Analogue Scale (VAS),the security,the analgesic effect and plasma β-endorphin content in the two groups were compared.Results The postoperative VAS scores at 2,4,8,16,24 and 48 h in the acupuncture group were lower than those in the medication group (all P＜0.05).The analgesic effects at 2,4,16 and 24 h after surgery in the acupuncture group were superior to those in the medication group (P＜0.05,P＜0.01).The plasma β-endorphin contents at 0,8,16 and 48 h after surgery in both groups were increased,and the acupuncture group was superior to the medication group (all P＜0.05).The security class after surgery in the acupuncture group was higher than that in the medication group (P＜0.05).Two cases in acupuncture group stopped treatment due to overstress and fear of needling,24 cases in medication group presented adverse reactions,among them,3 cases stopped the treatment due to nausea,vomiting.Conclusion The analgesic effect and safety of electroacupuncture at Nèimádiǎn(内麻点 Extra) after abdominalsurgery are superior to those of the PCIA with Sufentanil.
