This study was designed to quantitatively compare the effects of 1.5% xylocaine with 1.5% xylocaine and fentanyl (1 μg/kg) mixture for supraclavicular brachial plexus block.
Sixty patients between the age group of 20-60 and scheduled for upper limb surgery were divided into two groups (xylocaine group and xylocaine plus fentanyl group). After performing supraclavicular brachial plexus block, an assessment was made for onset of analgesia, duration and degree of analgesia, block intensity, and for any other side effects.
Mean duration of analgesia is Group I is 2.1 h and in Group II is 8.1 h; a four-fold increase in duration of analgesia.
Addition of fentanyl to xylocaine for supraclavicular brachial plexus block has no significant effect on onset or quality of analgesia, but duration of analgesia is significantly prolonged.
本研究旨在定量比较1.5%利多卡因与1.5%利多卡因和芬太尼（1μg/kg）混合液用于锁骨上臂丛神经阻滞的效果。
将60例年龄在20 - 60岁、计划行上肢手术的患者分为两组（利多卡因组和利多卡因加芬太尼组）。在进行锁骨上臂丛神经阻滞后，评估镇痛起效时间、镇痛持续时间和程度、阻滞强度以及任何其他副作用。
第一组的平均镇痛持续时间为2.1小时，第二组为8.1小时；镇痛持续时间增加了四倍。
在锁骨上臂丛神经阻滞中，向利多卡因中添加芬太尼对镇痛的起效时间或质量没有显著影响，但镇痛持续时间显著延长。
