We tested the hypothesis that the addition of 75 micrograms fentanyl to 0.5% bupivacaine would reduce the onset time of surgical anesthesia for cesarean delivery to equal the onset time of 3% 2-chloroprocaine and would have no effect when added to 3% 2-chloroprocaine. Fentanyl was found to reduce the onset time of bupivacaine to equal the onset time of 2-chloroprocaine and have no effect when added to 2-chloroprocaine.
在0.5%布比卡因中添加75微克芬太尼会使剖宫产手术麻醉的起效时间缩短至与3%氯普鲁卡因的起效时间相同,而添加到3%氯普鲁卡因中则不会产生影响。结果发现,芬太尼可使布比卡因的起效时间缩短至与氯普鲁卡因的起效时间相同,而添加到氯普鲁卡因中则无影响。
