Severe pain experienced by patients following any anal operations has been well known to the surgeons and patients. Patients are often reluctant to undergo necessary operations because of the fear of this pain. During the period between January 1, 1987 and December 31, 1987, a total of 45 patients underwent anal operations under intrathecal or epidural anesthesia. Morphine was added to the usual anesthetics at the time of anesthesia: 0.25ㅡ0.5mg for intrathecal anesthesia and 2ㅡ4mg for epidural anesthesia. Postoperative pain was completely absent from 7 to 18 hours with the addition of morphine. There was no complications related to the addition of morphine including respiratory depression. The severity of postoperative pain depends on the operative technique and postoperative use of analgegics. The addition of morphine during intrathecal or epidural anesthesia showed definite benefit for the control of postoperative pain after anal operations.
