碳酸利多卡因用于肌间沟臂丛神经阻滞的效果观察

目的观察碳酸利多卡因用于肌间沟臂丛神经阻滞的临床效果及安全性。方法选择ASAⅠ-Ⅱ级拟行桡尺骨切开复位内固定手术患者60例，随机分为Ⅰ、Ⅱ组，每组30例，Ⅰ组用15ml碳酸利多卡因＋15Ⅱd生理盐水，Ⅱ组用15ml碳酸利多卡因＋15ml生理盐水＋肾上腺素50峭行肌间沟臂丛神经阻滞，比较两组的麻醉起效时间、阻滞完全时间、对桡尺神经麻醉效果的优良率以及麻醉过程中生命体征的变化。结果两组患者感觉阻滞起效时间、感觉完全起效时间、运动阻滞完全起效时间，比较差异无统计学意义（P〉0．05）；两组上肢感觉恢复时间比较差异有统计学意义（P〈0．05）。结论碳酸利多卡因加肾上腺素用于前臂手术是安全和满意的。

Clinical observation of interscalene brachial plexus block with lidocaine carbonates

Objective To investigate the clinical efficacy and safety of interscalene brachial plexus block with lidocaine carbonates. Methods Sixty cases with forearm fracture scheduled for undergoing open reduction and imemal fixation were randomly assigned to two groups ： group Ⅰ （30 cases） recervied brachial plexus block with lidocaine carbonates 15 ml and NS 15 ml,while the group Ⅱ （30 eases） recervied braehial plexus block with lidocaine carbonates 15 ml, NS 15 ml and adrenaline 50 μg. Parameters of circulation and respiration were monitored to observe anesthesia efficacy, complications and adverse reactions. The onset and duration of sensory and motor nerve blockade in two groups were compared. Results There was no signifieante difference between the two groups in the hemodynamic changes and onset of total bolockade of sensory and motor never between two groups （ P 〉 0. 05 ）. But duration of sensory nerve blockade in group Ⅱ was longer than that in group Ⅰ （P 〈0. 05 ）. Conclusion Braehial plexus block with lidocaine carbonates is safe and satisfactory in forearm fracture surgery.
