A double-blind comparison of prilocaine and prilocaine plus potassium chloride, and of bupivacaine with bupivacaine plus potassium chloride, in brachial plexus blockade (axillary approach) was obtained in two groups of 20 patients. The addition of potassium chloride made no difference to the characteristics of the block with prilocaine, but resulted in a more rapid onset of sensory loss when added to bupivacaine.
在两组各20例患者中，采用腋路法进行臂丛神经阻滞，对丙胺卡因与丙胺卡因加氯化钾、布比卡因与布比卡因加氯化钾进行了双盲比较。氯化钾的添加对丙胺卡因的阻滞特性没有影响，但添加到布比卡因中会导致感觉丧失的起效更快。
