Abstract

The changes of onset and duration of caudal epidural anesthesia had been compared in 54 patients schedulled for perianal surgery at kyungpook National University HospitoL The patients were divided into 3 groups of 18: lidocaine group received 2% lidocaine 20 ml, mixture group received 2% lidocaine 10 ml and 0.5% bupivacaine 10 ml and bupivcaaine group received 0.5% bupivacaine 20 ml. The onsets were as follows. The onsets wiere 3.11+/-0.63 in lidocaine group, 4.83+/-4.17 in mixture group and 8.13+/-3.49 min in bupivacaine group. The onset of bupivacaine group was slower than lidocaine group(p<0.01) and late compared with mixture group(p<0.5). The duration of caudal anesthesia were 192.00+/-62.49 in lidocaine group, 326.72+/-145.28 in mixture group and 419.22+/-125.37min in bupivacaine group. Significant differences were observed between mixture-lidocaine group(p<0.01), bupivacaine-lidocaine group(p<0.01) and bupivacaine-mixture group(p<0.05). Urinary catheteiized patients were 8 in longest duration group of bupivacaine. It is suggested from the above'results that the mixture of lidocaine and bupivacaine during caudal epidural anesthesia can produce rapid onset and long duration.
