Abstract

Background: Digit replantation under wide-awake local anesthesia is a challenging method, and there are only a few works of literature on this procedure. This article describes the authors' clinical experience in finger replantation under wide-awake local anesthesia compared to general anesthesia.

Methods: Fifty-one patients who received single finger replantation after initial sharp amputation were included in the study, of whom 16 received wide-awake local anesthesia and 35 general anesthesia treatment. The indications for wide-awake local anesthesia were sharp amputation injury, estimated operation time less than 3 hours, and cooperative patients. The wide-awake local anesthesia was performed with 1% or 2% lidocaine infiltrated at the volar midpoint of the metacarpophalangeal joint of the affected digit without sedation medications. Demographic data included surgical outcome, waiting time, operation time, and hospital stay.

Results: A total of 51 consecutive patients were included in this study. There were significantly shorter waiting times and operation times in the wide-awake local anesthesia group. The other parameters showed no significant differences. The overall success rate was 76.47 percent, with a mean overall operation time of 207 minutes.

Conclusions: In selected patients, finger replantation can be successfully performed under wide-awake local anesthesia, which has lower anesthesia risk and fewer medical expenses than general anesthesia. The method is feasible for single-digit replantation. Therefore, the finger replantation under wide-awake local anesthesia is a practicable alternative to general anesthesia.

Clinical question/level of evidence: Therapeutic, III.
