PURPOSE: This study aimed to compare the effects of remifentanil and esmolol on the elevation of intraocular pressure (IOP) and hemodynamic response. METHODS: After approval of the institutional Ethics Committee and obtaining informed consent, 60 adult patients with American Society of Anesthesiologists I-II status undergoing elective, nonophthalmic surgery were included in the study. Exclusion criteria were preexisting eye disease, neuromuscular disease, esophageal reflux, hiatus hernia, allergy to any of the study drugs, and the use of β-blockers, diuretics, or other antihypertensive agents. The patients were randomized into 2 groups by using the sealed-envelope method, as follows: group E (esmolol) and group R (remifentanil). A single intravenous dose of esmolol (0.5 mg/kg) or remifentanil (1 μg/kg) just before induction agents were given to patients in groups E and R, respectively. IOP, heart rate (HR), and mean arterial pressure (MAP) values were recorded before intubation and at 1, 3, 5, and 10 minutes after intubation. RESULTS: The IOP decrease in group R was statistically significant compared with group E (P<0.01). HR values at 10 minutes after intubation were significantly decreased in group E compared with group R (P<0.05). There was no significant difference in MAP values between the groups. CONCLUSIONS: It was concluded that remifentanil is more effective than esmolol in preventing IOP elevation related to laryngoscopy and tracheal intubation, while there is no significant difference between the 2 agents in terms of HR and MAP.
