术前HANS对剖宫产术中及术后病人的镇痛作用

目的：观察术前应用韩氏穴位神经刺激仪（ＨＡＮＳ）对术后病人自控硬膜外镇痛（ＰＣＥＡ）效果、镇痛药用量及不良反应的影响。方法：选取ＡＳＡⅠ级剖宫产产妇４０例。ＨＡＮＳ组（ＨＡＮＳ＋ＰＣＥＡ组）２０例：术前应用ＨＡＮＳ且术后进行ＰＣＥＡ；对照组（ＰＣＥＡ组）２０例：单纯术后ＰＣＥＡ。ＨＡＮＳ采用ＤＤ波（２／１００Ｈｚ）刺激３０ｍｉｎ后切皮。记录切开腹膜、分离膀胱反折、婴儿娩出、清理宫腔、探查附件、术后

PREOPERATIVIVE HANS STMULATION AND ITS EFFECT ON POSTOPERATIVE PAIN IN PATIENTS UNDERGOING CESAREAN SECTION

Aim: To observe the effects of pre operative HANS on the dose of the patient controlled epidural analgesia (PCEA) and aversive side effects of PCEA, 40 ASA I patients undergoing Cesarean section were randomly divided into two groups: HANS group (20 cases) was given HANS preoperatively and PCEA postoperativly; control group (20 cases) was given PCEA only. For HANS stimulation, 2/100Hz wave was used for 30 minutes. The VAS score was recorded in eight time points (opening peritoneum; detaching peritoneum between uterus and bladder; fetal delivery; clearing cavity of uterus; exploring adnexa; 6 h, 12 h and 24 h after the operation), the doses of analgesics and complications were also observed. Results: HANS group had significantly less VAS scores than the control group. The dose of analgesics used in HANS group was not significantly less than the control group. The incidence of nausea and vomiting was significantly less in HANS group. Conclusion: preoperative use of HANS reduces pain during and after operation, and reduces the incidence of nausea and vomiting.
