Abstract : Aim:The purpose of this study was to evaluate the efficacy of transtracheal lidocaine injection to reduce the anesthetic requirements in patients who underwent brachial plexus surgery under general anesthesia.Settings and Design:This was a prospective randomized controlled study conducted in 40 consecutive adult patients.Materials and Methods:The patients were randomly allotted to two groups of 20 patients each. Group A patients received a transtracheal injection of 4 ml of 2% lidocaine before induction of anesthesia and group B patients did not receive it. The two groups were compared in terms of intraoperative propofol requirements and hemodynamic parameters.Statistical Analysis Used:Statistical analysis was done using Student's t-test for independent samples.Results:The propofol requirements were significantly less in group A in terms of the number of intraoperative events requiring propofol bolus at various time intervals in 3 h duration (4 vs. 77), the number of patients requiring propofol bolus injections (2 vs. 20), propofol infusion (0 vs. 20), and total propofol requirement (6 vs. 377 mg). After induction, patients in group B showed a statistically significant high heart rate, systolic blood pressure, and mean arterial pressure.
