AbstractEpidural anesthesia is an effective means of providing pain control and chemical sympathectomy at the spinal nerve root level. The purpose of this study is to compare the efficacy of the combination of epidural and general anesthesia to general anesthesia alone in patients undergoing free flaps to the lower extremity. A retrospective review of 35 consecutive patients (36 operations) from November of 1988 to November of 1990 undergoing free tissue transfer to the lower extremity was undertaken. Sixteen patients had epidural and general anesthesia, and 19 (20 operations) had general anesthesia alone. There were no significant differences in the age or sex of the patients, the distribution between acute and chronic wounds, or the number of cigarette smokers in the two groups. There were no flap losses in the epidural group (100 percent success) and one major, but nonmicrovascular complication (6 percent). In the nonepidural group, there were one flap loss (95 percent success) and five major complications (25 percent). These included three microvascular complications (15 percent). There were significantly fewer patients with postoperative atelectatic fevers in the epidural group versus the nonepidural group. In this consecutive series of patients, epidural supplementation of general anesthesia for free flaps to the lower extremity was associated with uniformly successful flap survival and a lower rate of microvascular complications compared to general anesthesia alone.
