【摘要】目的:观察泵速对剖宫产术后硬膜外镇痛效果的影响。方法:60例ASAⅠ~Ⅱ级的剖宫产术病人,均在硬膜外麻醉下完成手术并实行硬膜外术后镇痛,根据泵速不同将病人随机分为三组,每组20例,A组:0.15%布比卡因+芬太尼0.4mg,100mil泵速2.1mil/h;B 组:0.15%布比卡因+芬太尼0.4mg,168mil,泵速3.5mil/h;C 组:0.15% 布比卡因+芬太尼0.4mg,240mil,泵速 5ml/h。观察病人术后6h、18h、24h、48h,镇痛效果及不良反应。结果:三组患者年龄、体重、手术时间及术中绝对平面无显著性差异(P>0.05);术后各时间段B 、C两组VAS评分均低于A组(P<0.05);术后24h B、 C两组的阻滞节段数均大于A组(P<0.05);三组病人术后镇痛的副作用,C组的下肢麻木发生率较A、B两组高(P<0.05)。结论:泵速直接影响剖宫产术后硬膜外镇痛效果,3.5mil/h 的泵速既可产生良好的镇痛效果,又不影响病人的下肢活动,可作为首选。

【Abstruct】Objective:To observe the influnce of pump speed to the effect s of epidural analgesia after cesarean section. Methods:ASAⅠ~Ⅱ 60 patients undergoing cesarean section were all received epidural analgesia and post-operative epidural analgesia.According to different pump speed,patients were randomly divided into three groups with 20 cases each. Group A:0.15%Bupivacaine+Fentanyl 0.4mg,100ml,pump speed was 2.1ml/h;Group B:0.15%Bupivacaine+Fentanyl 0.4mg,168ml,pump speed was 3.5ml/h;Group C:0.15% Bupivacaine+Fentanyl 0.4mg,40ml pump speed was 5ml/h.The VAS and side effects were recorded at 6h.18h.24h.48h of postoperation. Results:Age Weight Operation time and the numbers of block segments in operation showed no difference in three groups.(P>0.05) ;At all recorded points of postoperation,the VAS of groupB and groupC were lower than groupA(P<0.05):At 24h of postoperation,The numbers of block of segments of groupB and groupC were more than groupA(P<0.05);About the side effects in three groups,the rate of legs numb in group C was higher than groupA and groupB(P<0.05). Conclusion:The pump speed can influence the effects of epidural analgesia after cesarean section.The speed was of 3.5ml/h can provide a good analgesia and no legs numb, it is the best choice.

硬膜外术后镇痛已广泛应用于临床, 其镇痛效果肯定,但不同泵速对镇痛效果的影响报道较少,我们采用不同泵速对剖宫产病人进行术后镇痛,观察其镇痛效果及不良反应,旨在选择最适的泵速,以期既能产生满意的镇痛效果,又把副作用减到最低。
