臂丛神经阻滞液加用小剂量吗啡用于术后镇痛的效果观察

Brachial Plexus Block with Low-dose Morphine Used to Observe the Effect of Postoperative Analgesia

目的:观察局麻药中加用小剂量吗啡用于臂丛神经阻滞对于术后镇痛时间、程度的影响。方法:90例ASAⅠ-Ⅱ级在肌间沟臂丛神经阻滞下行上肢手术的患者随机均分为A、B、C三组。A组患者注入2%利多卡因与0.5%布比卡因等量混合液22.5ml;B组注入A组用药后,肌肉注射吗啡2mg;C组注入A组用药内加用吗啡2mg。观察三组术后镇痛满意度、镇痛持续时间及不良反应。结果:三组患者术中生命体征变化及不良反应无显著性差异,而术后疼痛出现的时间、疼痛的程度有比较明显的差异。结论:臂丛神经阻滞加用小剂量吗啡能明显延迟术后疼痛出现的时间,并使疼痛的程度明显降低。

Objective：To investigate the postoperative analgesia effect and the duration of the analgesia time of the addition of low-dose morphine to local anesthetic during brachial plexus block. Methods：Ninety patients（ASA Ⅰor Ⅱ） scheduled for upper limbs surgery under interscalene brachial plexus block anesthesia were randomly divided into three groups：22. 5ml 2% lidocaine and 0. 5% bupivaeaine were injected into in group A,2mg morphine inject muscle after group A medicine in group B,2mg morphine was plused to group A medicine in group C. Patients postoperative analgesia satisfaction,postoperative pain relief time and side effects were recorded. Results：There were significant differences in the appearance time of postoperative pain and pain degree,whereas no differences among three groups in vital signs and side effects. Conclusion：Low-dose morphine was plused into local anesthetic of brachial plexus block can delay the appearance time of postoperative pain and decrease the pain degree.
