Comparison of onset time between 0.5% bupivacaine and 3% 2-chloroprocaine with and without 75 micrograms fentanyl.
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.
