电针治疗手术后疼痛刺激参数的研究现状和分析

Current Research Status and Analysis of Electroacupuncture Parameters for Post-operative Pain

目的探索电针治疗手术后痛的皮肤切口痛和内脏牵拉痛的最佳刺激参数。方法采用计算机检索中国知网（CNKI）、万方数据库（WF）、维普咨询网（VIP）和Pub Med数据库,对符合纳入标准文献按相关参数进行频次统计,对电针治疗手术后痛的临床及实验研究文献进行总结。结果电针治疗皮肤切口痛的参数范围为术后治疗,选用连续波型,频率为2-15 Hz,集中在低频率,电流强度为2-5 m A;电针治疗内脏牵拉痛多在术前进行,选用疏密波,高低交替频率,以2/100 Hz为主,电流刺激强度主要集中在中低强度,以患者能够忍受为度。结论电针治疗手术后疼痛不同类型所用刺激参数不同,临床应用时应注重具体参数的选择。

Objective To find the optimal stimulation parameters of electroacupuncture for incision pain and visceral dragging pain after surgery. Method Databases including the China National Knowledge Infrastructure （CNKI）, WanFang （WF）, VIP and PubMed were retrieved by using computer. The eligible literatures related to the clinical and experimental studies on electroacupuncture for post-operative pain were summarized and the frequencies of the involved electroacupuncture parameters were counted. Result For incision pain, electroacupuncture was used after surgery, with continuous wave, usually a low frequency ranged 2- 15 Hz and a current of 2-5 mA; for visceral dragging pain, electroacupuncture was used before surgery, with sparse-intense wave, alternate frequencies majorly at 2/100 Hz and a medium or low current intensity within patient＇s endurance. Conclusion In clinical application, the elctroacupuncture parameters should be chosen carefully according to the type of post-operative pain.
