488 hand surgeries with local anesthesia with epinephrine, without a tourniquet, without sedation, and without an anesthesiologist.

Objectives: Evaluate the incidence of digital infarction and tissue necrosis using local anesthesia with 1% lidocaine and 1:100,000 epinephrine in wrist, hand, and fingers surgeries, without a tourniquet, without sedation, and without an anesthesiologist.

Methods: Patients with wrist, hand, and fingers disorders prospectively underwent surgery under local anesthesia with 1% lidocaine and 1:100,000 epinephrine. The primary outcomes evaluated were the presence of digital infarction and tissue loss due to necrosis.
