Perivascular axillary block was performed on 80 patients by a catheter technique. All patients had a standard dose of 40 ml mepivacaine 1% with adrenaline. Thirty minutes after the injection, the motor and sensory blockade was determined. Eighty-six per cent of the patients had a distinct motor blockade, whereas the remaining 14% had only a slight motor blockade. The sensory blockade was complete in 63%, whereas 37% had lack of analgesia in one or several cutaneous areas. Lack of analgesia was most often found in the cutaneous area of the axillary, musculocutaneous and radial nerves. The frequency of analgesia in the three areas of innervation was analysed with reference to the influence of the age, height and weight of the patient, and of differences in technique: paraesthesias, position of catheter, and unintended puncture of blood vessels. None of these variables seems to be important for the low frequency of analgesia in the three areas of innervation.
采用导管技术对80例患者实施血管周围腋路阻滞。所有患者均接受标准剂量的含肾上腺素1%甲哌卡因40毫升。注射30分钟后，测定运动和感觉阻滞情况。86%的患者有明显的运动阻滞，而其余14%仅有轻微运动阻滞。63%的患者感觉阻滞完全，而37%在一个或几个皮肤区域存在镇痛缺失。镇痛缺失最常出现在腋神经、肌皮神经和桡神经的皮肤区域。参照患者年龄、身高和体重的影响以及技术差异（异感、导管位置和意外血管穿刺）分析了这三个神经支配区域的镇痛频率。这些变量似乎对这三个神经支配区域镇痛频率较低均无重要影响。
