小剂量利多卡因臂丛神经阻滞用于肩关节复位的临床意义

Clinical Significance of Low - dose Lidocaine in Brachial Plexus Block for Reduction of Shoulder Dislocation

目的:探讨小剂量利多卡因臂丛神经阻滞用于肩关节复位的临床价值。方法:86例ASAⅠ—Ⅱ级肩关节脱位病人随机分为两组,采用臂丛神经阻滞,小剂量组注入1.5％利多卡因5ml,对照组注入1.5％利多卡因20ml。观察复位效果,同时观察神经阻滞前后血压心率变化、记录起效时间及不良反应发生情况。结果:两组患者复位都易于成功,但小剂量组无并发症发生。结论:小剂量利多卡因臂丛神经阻滞用于肩关节复位是一种安全、有效的方法。

Objective: To assess the clinic value of low - dose lidocaine in brachial plexus block for reduction of shoulder dislo-cation. Methods: 86 cases of shoulder dislocation , ASA grade Ⅰ-Ⅱ ,were divided randomly into two groups, all patients re-ceived Hippocrate' s reduction under brachial plexus block. Patients in the low - dose lidocaine group received 1.5% lidocaine 5 ml, patients in the control group received 1.5% lidocaine 20 ml.The effect of redution was observed. BP and HR were moni-tored and its onset of analgesia and complications were recorded. Results : In all cases, reductions were easy, but patients in low - dose group were free from complications . Conclusion: Low - dose lidocaine in brachial plexus block may be used for reduction of shoulder dislocation, and it is safe and efficacious.
