The Effect of Intravenous Lidocaine on Pain After Tonsillectomy
Summary
This prospective randomized study aims to evaluate the effectiveness of intravenous lidocaine injection on the relief of pain in patients undergoing tonsillectomy. A total of 62 patients will be randomized into one of two groups (group C or group I) based on Excel number generation. Patients in group C will receive received normal saline intravenous injection, and patients in group I will receive an intravenous bolus injection of 1.5 mg/kg lidocaine followed by a continuous lidocaine infusion of 2 mg/kg/hr. Visual analogue scale pain scores, fentanyl consumption and the frequency at which patients pushed the button (FPB) of a patient-controlled analgesia system will be recorded at 4, 12, 24, 48 hours postoperatively.
