Summary
This multicenter, prospective randomized controlled trial investigates the effect of dilute epinephrine irrigation versus tourniquet use on visual field clarity (VFC) during ankle arthroscopy. Patients are randomized into an epinephrine group (normal saline with 1 mL of 1:1000 epinephrine per 3 L bag; tourniquet placed but not inflated unless needed) or a standard tourniquet group. The primary outcome is arthroscopic visual field clarity assessed using a 4-point Likert-style numeric rating scale. Secondary outcomes include postoperative pain intensity at 2 and 24 hours (VAS), and the incidence of hypotension, bradycardia, and cardiovascular adverse events.
