Background: Muscle relaxant agents usually use to facilitate tracheal intubation; however, sometimes limitations exist. Magnesium (Mg) sulfate is a candidate for muscle substitute. This study was designed determine the effect of Mg accompanied with propofol and fentanyl in patients undergoing ophthalmic surgery. Materials Methods: In double-blind randomized protocol before intubation, 40, 45, or 50 mg/kg 100 ml saline (Groups 1–3, respectively) alone (Group 4) were administrated intravenously (n = 25 each group) American Society Anesthesiologist (ASA) physical Status I, II, III. The patients' intubation condition all subjects determined described. Results: demographic data including age, ASA, systolic diastolic blood pressures, intraocular pressure, body mass index not significantly different between groups. A better mask ventilation feasibility 45 group 2) observed when compared 3) (P 0.022) 0.021). addition, vocal cord movement requirement from others groups < 0.05). laryngoscopic time greater than other 0.0001). Conclusion: Intravenous administration facilitates without neuromuscular blocking agents. To avoid level increasing plasma; low dose suggested.
