Wide-Awake Surgery With Local Anesthesia and Epinephrine Is Safe.

Hand and upper extremity surgery performed with the patient wide awake involves the use of a local anesthetic and epinephrine. Controversy persists as to whether epinephrine is safe for use in the hand. The goal of this study was to evaluate the safety of epinephrine in hand and upper extremity surgery. The hypothesis was that epinephrine is safe and can be used for a wide breadth of surgical procedures of the hand and upper extremity. A 4-year retrospective chart review was conducted of consecutive patients undergoing wide-awake surgery performed by 2 surgeons at a single institution. All procedures were performed with local anesthesia and epinephrine. Data collected included patient demographics, procedure volume, procedure type, surgical setting, and complications related to epinephrine use. During the study period, 4054 consecutive patients underwent 4287 wide-awake procedures with local anesthesia and epinephrine. Average patient age was 59 years, and 64% of patients were female. No complications occurred as a result of the use of epinephrine, and no tissue necrosis, phentolamine reversal, anaphylaxis, or readmissions occurred. No patients required conversion to general anesthesia or monitored anesthesia care. This analysis of more than 4000 consecutive patients undergoing wide-awake hand and upper extremity surgery with epinephrine confirmed that epinephrine use is safe, with no reported cases of tissue necrosis, reversal, readmission, anaphylaxis, or anesthetic conversion. Epinephrine is safe for use in the hand and upper extremity for patients undergoing wide-awake hand surgery with a local anesthetic. [Orthopedics. 2020;43(6):e529-e532.].
