A Pilot Study: 0.2% vs. 0.5% Lidocaine For Intravenous Regional Anesthesia
Abstract:Background: Standard intravenous regional anesthesia (IVRA) uses 3 mg/Kg of 0.5% lidocaine. However, a lower dose, larger volume lidocaine may be as effective. Methods: Randomized single blind study of emergency department patients with closed Colles fractures reduced with either 3 mg/Kg (0.6 mL/Kg) 0.5 % lidocaine (N=11) or 2 mg/Kg (1.0 mL/Kg) 0.2% lidocaine (N=10). Anesthesia outcome measured with 4-category pain rating scale. Results: Analysis of pooled data showed no significant difference in pain rating b… Show more
