摘要
目的探讨硬膜外腔注射吗氟合剂预先镇痛对腰硬联合麻醉中及术后镇痛的影响。方法60例在腰硬联合麻醉下全宫切除术,按美国麻醉医师协会病人ASA分级为Ⅰ-Ⅱ级病人,随机分成三组,A组为对照组,B组为全量预先镇痛组,C组为半量预先镇痛组,观察三组术中镇静程度(Ramesay评分)、脉搏血氧饱和度(SpO2)、术后镇痛效果、疼痛视觉模拟评分(VAS评分)、镇痛有效时间。结果Ramesay评分A组≈B组>C组,VAS评分A组≈B组≈C组(所有病例均<3分),镇痛有效时间A组≈C组>B组。结论对于腰硬联合麻醉辅助静脉镇痛镇静手术病人来说,硬膜外腔注射吗氟合剂预先镇痛可减少术中静脉辅助药量,对术后镇痛效果影响不大;但合理的用药时机可延长术后镇痛时间,使用术前硬膜外腔预注吗氟合剂半量,关腹前再注入余量的方法更能保证术后止痛有效时间。
Objective To study the effect of preemptive analgesia with morphine and droperidol in combined spinal -epidural anesthesia and postoperative analgesia. Methods 60 patients are randomly divided into three groups; pulse oxygen saturation （SPO2） ,effects of analgesia , VAS Scores and Ramsay scores are recorded in operation. Results Ramsay scores： group A ≈ B 〉 C; VAS scores ：group A B ≈ C ; duration of analgesia： group A ≈ C 〉 B. Conclusion Preemptive analgesia can reduce the drug dosage in vein. It has little impact on the effect of analgesia, but may increase the time of postoperative analgesia. It is apparent that group C indicates effective postoperative analgesia.
