Objective: To evaluate the efficacy of esmolol in modifying hemodynamic response to laryngoscopy and endotracheal intubation. Materials and methods: ASA I-II 60 subjects, aged between 20-50 years, were included in this prospective, randomized and single-blind study. Patients were divided into two groups. Group Esmolol(Group E) and Group Control (Group C) received IV bolus of esmolol 1.5 mg/kg and %5 dextrose 5 cc respectively, 2 minutes before laryngoscopy and intubation. We recorded heart rates (HR), mean arterial pressures (MAP), and rate pressure products (RPP) preoperatively, after induction and intubation and in 1st, 3rd, 5th, 7th, and 10th minutes after intubation. Results: In Group C, HR decreased after induction in 5th, 7th, and 10th minutes, whereas it increased after intubation. In Group E, HR decreased after induction, in 3rd, 5th, 7th, and 10th minutes (P Conclusion: This dose of esmolol was effective in controlling the tachycardia and RPP, but it was ineffective in controlling the hypertensive response to laryngoscopy and endotracheal intubation.
