术前疼痛程度（VAS评分）对硬膜外术后镇痛的影响

摘要

Objective To investigate the ef ects of preoperative pain degree (VAS score)on postoperative epidural analgesia.Methods Two hundred patients undergoing cesarean section and require for postoperative analgesia were divided into 4 groups according to preoperative pain degree (VAS score):group A:VAS=0;group B:05;PCEA formula:0.1%ropivacaine 200ml+sufentanil 0.2ug/ml,the maintenance dose was 4ml/ml,PCA dose 1ml/second,locking time was 15min and the duration of PCEA was 48h.VAS was applied for evaluating analgesia ef ects and Sid ef ects of al groups were observed.Results There were no significant dif erence between four groups in analgesia ( >0.05).Conclusion Preoperative pain degree has no ef ects on postoperative epidural analgesia.%目的：观察术前疼痛程度(VAS评分)对硬膜外术后镇痛的影响。方法选择腰-硬联合麻醉下剖宫产术、要求术后镇痛产妇200例，按产妇术前疼痛程度(VAS评分)分成四组：A组VAS=0分；B组0分5分。 PCEA配方：0.1%罗哌卡因200ml+舒芬太尼0.2ug/ml，输注背景为4ml/h,PCA：1.0ml/h,锁定时间15min，维持时间48h。用产妇术后各时点VAS评分、术后48h总PCA次数评价镇痛效果及对镇痛药物的需求量，并记录相关不良反应。结果四组产妇术后各时点VAS评分、术后48h总PCA次数无显著差异(P>0.05)。结论剖宫产产妇术前疼痛程度(VAS评分)对硬膜外术后镇痛效果没有显著影响，没有增加产妇对硬膜外术后镇痛用药量的需求。
