摘　　要：目的：评价剖宫产术产妇术前电刺激法测量的痛阈、耐痛阈与术后舒芬太尼消耗量之间的关系。方法：选择行择期腰硬联合麻醉下剖宫产术的产妇50例,年龄20～35岁,身高155～180 cm,美国麻醉医师协会（American Society of Anesthesiologists,ASA）分级Ⅰ～Ⅱ级。腰硬联合麻醉前应用电刺激仪测定痛阈和耐痛阈;术后行舒芬太尼患者自控静脉镇痛（patient controlled intravenous analgesia,PCIA）,舒芬太尼背景剂量0.015μg/（kg·h）,单次按压剂量0.023μg/kg,锁定间隔时间8 min。于术后4、8、24 h时记录视觉模拟评分（visual analogue scale,VAS）及舒芬太尼消耗量。对术前痛阈和耐痛阈与术后24 h VAS评分和舒芬太尼消耗量进行直线相关分析。结果：术前电刺激法测量的痛阈、耐痛阈与术后24 h VAS评分和舒芬太尼消耗量无相关性（P〉0.05）。结论：术前电刺激法测量的痛阈、耐痛阈不能预测剖宫产术后舒芬太尼消耗量。Objective：To evaluate the correlation of preoperative pain threshold and pain tolerance threshold with postoperative sufentanil consumptions in puerperae who underwent cesarean section.Methods：A total of 50 puerperae,aged 20-35 years,with height 155-180 cm,who were classified asⅠ～Ⅱ with American Society of Anesthesiologists（ASA）criteria and scheduled for cesarean section with combined spinal and epidural anesthesia（CSEA）,were chosen.The pain threshold and pain tolerance threshold were measured with electric stimulator before CSEA.The patient controlled intravenous analgesia（PCIA）with sufentanil was used for postoperative analgesia.The PCIA pump was set up with background infusion at a rate of 0.015μg/（kg·h）and single bolus dose of 0.023μg/kg with 8 min lockout interval.Visual analogue score（VAS）,as well as consumptions of sufentanil,was recorded at 4,8,24 h after operation.Linear correlation analysis was conducted on the preoperative pain threshold and pain tolerance threshold with the total sufentanil consumptions during the 24 h after operation and the VAS at the 24 h after operation.Results：The preoperative pain threshold and pain tolerance threshold measured by electric stimulation were not correlated with the VAS at the 24 h after operation and the sufentanyl consumption during the 24 h after operation（P〈0.05）.Conclusions：The preoperative pain tolerance threshold and pain threshold measured by electric stimulation cannot predict the consumptions of sufentanyl after cesarean section.
