Abstract
To compare the management of postoperative pain using morphine administered by epidural catheter with intravenous patient-controlled analgesia (PCA), we prospectively studied 47 consecutive cases involving repair of the anterior cruciate ligament of the knee. Both the quality of analgesia and the incidence of side effects were documented. Compared with patients receiving PCA morphine, patients given epidural morphine reported significantly lower pain scores both at rest (0.7 .+-. 1.1 versus 3.4 .+-. 2.1, P < 0.01) and with mobilization (3.2 .+-. 2.1 versus 6.1 .+-. 2.1, P < 0.01). Although patients receiving epidural morphine had a greater incidence of urinary retention, there were no significant differences in the incidence of nausea or pruritis. There was no respiratory depression in either group. We conclude that epidural morphine provides superior analgesia with a clinically inconsequential increase in side effects. Further, epidural morphine may have special advantages when early mobilization is indicated.
