胸腹部手术后止痛方法的改进

AN ALTERNATIVE METHOD FOR POSTOPERATIVE ANALGESIA AFTER THORACIC AND ABDOMINAL OPERATION

摘要:

目的 :观察低位 (L2～ 3)硬膜外腔注射吗啡用于胸腹部手术后止痛效果。方法 :随机选择 77例静吸全麻病人 ,分观察组 (L2～ 3硬膜外腔注射吗啡 ) ,对照组 (与手术区相应节段硬膜外腔注射吗啡 )各组均于全麻诱导前于硬膜外腔注入 1.6 %利多卡因 ,观察 5min ,全麻插管。手术结束前将吗啡 2 .5mg、氟哌啶 2 .5mg用生理盐水稀释到 8ml注入硬膜外腔。结果 :两组间镇痛有效率、镇痛持续时间相比较无显著性差异 (P >0 .0 5 )。结论 :腰部硬膜外腔注吗啡用于胸腹部手术后止痛与相应节段硬膜外腔注吗啡具有相同的止痛效果。

Abstract:

Objective: To compare the postoperative analgesic effect of 2.5mg epidural injection of morphine administered in lumbar segment or in the segment according to the surgical operation. Methods: Seventy seven patients undergoing thoracic and abdominal operation with general anesthesia were randomly divided into two groups 2.5mg morphine and 2.5mg dorperidol were injected epidurally into lumbar segments (groupl 1) or into the segment according to the operation (control group) after the operation. Results: Epidural injection of morphine could provide adequate postoperative analgesia and there was no significant difference in the lasting time of analgesia between the two groups.Conclusion: The analgesic effect of morphine injected epidurally into lumbar segment was similar to that injected into the segment according to the operation.
