Effect of bupivacaine combined with procaine orlidocaine on the brachial plexus blockade

Aim The onset of complete blockade of brachial plexus and its sustained time caused by bupivacaine alone or by the drug in combination with procaine and lidocaine were compared. Methods 8086 patients received forearm and hand operations were randomly divided into three groups,namely bupivacaine,bupivacaine plus procaine and bupivacaine plus lidocaine groups. Results The onset time of complete block was shorter and its sustained period was longer in bupivacaine plus lidocaine group than the other groups (P0.05 or P0.01).When used with adrenlline,bupivacaine in any dosage would bring a longer sustained period time(P0.01). With the anesthetic dose decreased,there was a drop in the onset time of complete block and the sustained period. Conclusion All the anesthetic methods could be used in upperlimb's operations in patients who have different pathogenies, physiques and operative times.
