Abstract

The use of low-dose epinephrine in hand surgery has made it possible to perform a wide range of surgical procedures in the office setting. Low-dose epinephrine use is safe, and its vasoconstrictive effects are reversible with phentolamine. In this report, we present late-onset finger ischemia beginning 3 hours after an ipsilateral carpal tunnel and A1 pulley release of the middle finger anesthetized with local anesthetic and low-dose epinephrine (1:100,000). Finger ischemia lasted 14 hours until rescued with phentolamine injection.
