Abstract
Attenuation of intubation response has been practiced by various methods and using drugs, topically or systemically. This study was undertaken to compare the effectiveness of magnesium sulphate and esmolol for attenuation of blood pressure response to laryngoscopy and intubation. Following ethical committee approval, patients fulfilling the essential criteria were selected. Patients were randomized and either received 0.5mg/kg esmolol or 30mg/kg magnesium sulphate intravenously and vital parameters were recorded. SBP and DBP in esmolol group showed statistically significant decrease from 1st to 10th minute after intubation from baseline. MAP in esmolol group showed statistically significant increase from baseline at intubation and decrease from 2nd to 10th minute after intubation from baseline.
