BACKGROUND: Levobupivacaine is a long acting local anesthetic with less cardiovascular toxicity. Recently we can use levobupivacaine for postoperative analgesia. We retrospectively compared levobupivacaine with ropivacaine for the postoperative epidural analgesia in patients undergoing gynecological abdominal surgery. METHODS: The patients who had received epidural and general anesthesia from October 2008 to April 2009 were allocated into two groups. Analgesia intensity, the time to receive the first analgesic, and the number of times to use the additional analgesics were observed for three postoperative days. RESULTS: There was no difference in demographic data between the levobupivacaine and ropivacaine groups. In the levobupivacaine group (n=23) the patient received epidural 0.24% levobupivacaine and fentanyl, while the patients in the ropivacaine group (n=43) epidural 0.19% ropivacaine and fentanyl, at the rate of 3.5 ml x hr(-1). The volume of epidural fentanyl was similar between the groups. The time from the end of surgery to receive the first analgesic was longer in the levobupivacaine group than in the ropivacaine group. The number of the patients who did not require additional analgesia was greater in the levobupivacaine group than in the ropivacaine group. The patients who received metocropramide to treat nausea were fewer in the levobupivacaine group, compared with the ropivacaine group. CONCLUSIONS: These results suggest that the use of epidural 0.24% levobupivacaine in the patients undergoing the gynecological surgery is superior to the use of 0.19% ropivacaine.
