We investigated the hypothesis that ephedrine-induced increases in blood pressure accelerate the regression of epidural block. In patients undergoing minor gynecologic surgery, we performed lumbar epidural blockade using 2% lidocaine containing 1:200,000 epinephrine to which was added 0.1 mg of fentanyl. Eighty minutes after the epidural injection, we started an ephedrine infusion to increase the systolic blood pressure by 20% in 10 min and maintained the value for the following 20 min. Then we compared the proximal extent of sensory analgesia at 80 min with that at 140 min. Ephedrine significantly (P = 0.001) hastened the regression of sensory analgesia. We conclude that an ephedrine-induced blood pressure increase accelerates regression of epidural blockade.
