韩氏穴位神经刺激仪(HANS)应用于腹部手术病人术后PCEA镇痛的临床研究

CLINICAL STUDY ON POSTOPERATIVE PATIENT-CONTROLLED EPIDURAL ANALGESIA BY THE APPLICATION OF HAN'S ACUPOINT NERVE STIMULATOR (HANS) ON ABDOMINAL SURGERY PATIENTS

本研究根据一定频率的经皮电刺激可促使中枢神经系统释放阿片肽的原理，应用韩氏穴位神经刺激仪（HANS）辅助腹部手术病人术后硬膜外腔吗啡自控镇痛20例（HANS组）与单纯术后硬膜外腔吗啡自控镇痛20例（对照组）比较。结果表明：吗啡用量HANS组150±192．6μg与对照组465±478．2μg相比有显著性差异（P＜0．05），镇痛效果VAS评分HANS组0．5±05且分与对照组0．9±0．64分相比有显著性差异（P＜0．05）。不良反应：胸闷、恶心，实验组与对照组相比有所减少。结论：HANS复合PCEA可使吗啡用量减少68％，提高镇痛效果并可减少不良反应，值得临床上推广应用。

It has been well established that peripheral electrical stimulation may stimulate central nervous systcm (CNS) releasing opioid peptides. We used Han's Acupoint Nerve Stimulator (HANS) to postoperative patients of abdominal surgery as an adjunct method for epidural patient-controlled analgesia of morphine. We compared 20 patients given epidural patient controlled analgesia in conjunction with HANS (HANS group) to 20 patients given only epidural patient-controlled analgesia (controll group). The results showed that morphine dosage in HANS group was 150±192. 6μg, as compared to 465±478. 2μg in controll group, showing a significant difference (P<0. 05 ); Concerning analgesic efficacy, the (VAS) in HANS group was 0. 5±0. 51, as compared to 0. 9±0. 64 in cotroll group (P< 0. 05 ); About aversive effects such as thoracic choking feeling and nausia, it was obviously less in HANS group than in controll group. The results indicate that the use of HANS can reduce morphine dosage, enhance analgesic efficacy and decrease adversive effects.
