The Effects of Lidocaine and Magnesium Sulphate on the Attenuation of the Hemodynamic Response to Tracheal Intubation

Summary

Justification and Objectives: The hemodynamic response to stimuli of the airways is a common phenomenon and its control is important to decrease systemic repercussions. The objective of this study is to compare the effects of intravenous administration of Magnesium Sulphate versus Lidocaine in the hemodynamics of this reflex after laryngoscopy and tracheal intubation. Methods: This double blind, randomized, single center, and prospective study evaluated 56 patients, ASA 1 or 2, aged between 18 and 65 years, scheduled for elective surgeries under general anesthesia with tracheal intubation. Patients were divided into two groups. Group M received 30mg/kg of Magnesium Sulphate, and group L 2 mg/kg of Lidocaine through continuous infusion, immediately before induction of anesthesia. The values for blood pressure (BP), heart rate (HR) and bispectral index (BIS) were measured in both groups at six distinct moments related to the administration of the drugs under study.
