The present study compared the efficacy of two different doses of labetalol, for attenuation of hemodynamic response to laryngoscopy and intubation in hypertensive patients. Patients and methods: 75 hypertensive patients, aged 18-60 years undergoing elective surgical procedures, require general anesthesia and orotracheal intubation. Patients were allocated to any of the three groups (25 each), Group C (control) 5 ml 0.9% saline. Group L1 (labetalol) 0.15 mg/kg diluted with 0.9% saline to 5 ml. Group L2 (labetalol) 0.3 mg/kg diluted with 0.9% saline to 5 ml. In the control group 5 ml of 0.9% saline was given i.v. 5 min prior to intubation. In the L1 group 0.15 mg/kg of labetalol was given i.v. 5 min prior to intubation. In the L2 group 0.3 mg/ kg of labetalol was given i.v. 5 min prior to intubation. All the patients were subjected to the same standard anesthetic technique. Heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded prior to induction, at time of intubation and 1, 3, 5, and 10 min after intubation. Mean arterial pressure (MAP) and rate pressure product (RPP) were calculated. Results: Compared to placebo both the doses of labetalol (0.15 mg/kg) and (0.3 mg/kg) significantly attenuated the rise in heart rate, systolic blood pressure, and RPP during laryngoscopy and intubation. However, the difference was not statistically significant between both doses of labetalol at intubation, 1 min, 3 min and 10 min post-intubation. Conclusion: Both doses of labetalol (0.15 mg/kg and 0.3 mg/kg) attenuate hemodynamic response to laryngoscopy and intubation in dose dependent manner.
