Abstract

BACKGROUND


In this study, we wanted to compare the efficacy of two different doses of Labetalol for controlling the hemodynamic responses to laryngoscopy and tracheal intubation under the same anaesthetic techniques in controlled hypertensive patients.


 


METHODS


This was a hospital-based prospective, randomized, and double-blinded study conducted among 96 patients who presented for a pre-anaesthetic check-up to the Department of Anaesthesiology and Critical Care, at Gauhati Medical College and Hospital, over a period of 1 year from 1st September 2021 to 31st August 2022 after obtaining clearance from the institutional ethics committee, and written informed consent from the study participants.


 


RESULTS


Intragroup comparison of mean SBP in patients receiving IV Labetalol 0. 15 mg/Kg and IV Labetalol 0. 3mg/Kg was statistically significant. In an intragroup comparison of mean DBP in patients receiving IV Labetalol 0. 15 mg/Kg, it was significant at 5 and 10 mins. In a comparison of changes in DBP and MAP at various predetermined time intervals i. e., at intubation, it was statistically significant. In an intragroup comparison of mean RPP in in patients receiving IV Labetalol 0. 3mg/Kg in comparison to the baseline, it was significant at 10 mins.


 


CONCLUSIONS


Both doses of IV Labetalol (0. 15 mg/Kg and 0. 3 mg/Kg), given 5 mins before endotracheal intubation are effective in attenuating the hemodynamic response to laryngoscopy and intubation in controlled hypertensive patients. In comparison to the IV Labetalol dose of 0. 15 mg/Kg, attenuation of hemodynamic response to laryngoscopy and endotracheal intubation was more in IV Labetalol 0. 3 mg/Kg.
