重复腋路臂丛麻醉不同穿刺定位法的效果比较

目的：观察应用不同穿刺定位法施行重复腋路臂丛阻滞麻醉效果。方法：３２４例随机分为两组，在局麻药浓度、容量相同的情况下，Ａ组采用一针穿刺单次给药逐次移位定向挤压法，１６２例中，臂丛阻滞７３０次；Ｂ组采用一针穿刺单次给药法，１６２例中，臂丛阻滞６７０次。结果：在诱导时间、维持时间和阻滞完全方面，Ａ组均明显优于Ｂ组。结论：臂丛神经处于椎前筋膜及其延续的筋膜间隙中，因此，一针穿刺单次给药能获得有效的阻滞。

Comparison of repetitive transaxillary brachial plexus block with different localization

Objective: The effect of repetitive transaxillary brachial plexus block with different localization were observed. Methods: 324 patients were randomly divided into two groups while using the same anesthetic concentration and dose. In group A, the anesthesia was accomplished by one puncture, in a lump infusion, with gradual transposition and orienting massage, involving 730 blocks in 162 patients. In group B, It was done by one puncture and in a lump infusion, involving 670 blocks in 162 patients. Results: The anesthetic effect in group A was far superior to that observed in group B, as such parameters as inducing time, lasting time and blockage extent were concerned. Conclusion: Brachial plexus lies in the prevertebral fascia and the space under the fascia. Therefore one puncture with a lump infusion can result in effective blockage.
