The role of magnesium sulfate in tracheal intubation without muscle relaxation in patients undergoing ophthalmic surgery.

Background: Muscle relaxant agents usually use to facilitate tracheal intubation; however, sometimes limitations exist. Magnesium (Mg) sulfate is a candidate for muscle relaxant substitute. This study was designed to determine the effect of Mg sulfate accompanied with propofol and fentanyl in patients undergoing ophthalmic surgery.

Prevention of post-spinal hypotension using crystalloid, colloid and ephedrine with three different combinations: A double blind randomized study.

Background: The benefit of prophylactic combination therapy using crystalloid and colloid preload with ephedrine has not been cleared to prevent maternal hypotension after spinal anesthesia at cesarean delivery. This study evaluated the efficacy of three combinational methods to prevent hypotension following spinal anesthesia.

Materials And Methods: In this prospective double blind trial, 150 candidates of elective cesarean delivery under spinal anesthesia were randomly allocated to three treatment groups; 1---Ringer's Lactate (RL) solution (15 ml/kg) plus Hemaxel (7 ml/kg) preload, 2---RL solution (15 ml/kg) preload plus ephedrine (15 mg, IV, bolus), 3---Hemaxel (7 ml/kg) preload plus ephedrine (15 mg, IV, bolus).

A randomized comparative trial of combinational methods for preventing post-spinal hypotension at elective cesarean delivery.

Background: Various methods have been applied to prevent maternal hypotension after spinal anesthesia for cesarean delivery. We compared the efficacy of three combinational methods in this regard in the current study.

Methods: In this randomized comparative trial, 150 candidates of elective cesarean delivery under spinal anesthesia were assigned to three groups: crystalloid preload and leg bandage, colloid preload and leg bandage, and ephedrine and leg bandage.

Effect of cisatracurium versus atracurium on intraocular pressure in patients undergoing tracheal intubation for general anesthesia.

Background: Increase in intraocular pressure (IOP) following tracheal intubation during general anesthesia can be troublesome. We compared the influence of two muscle relaxants, cisatracurium and atracurium, on IOP in patients undergoing general anesthesia.

Methods: This randomized, double-blind, comparative trial was conducted on 90 candidates for elective non-ophthalmic surgery under general anesthesia.

The effect of different lidocaine application methods on postoperative cough and sore throat.

Study Objective: To evaluate the efficacy of various ways of lidocaine application in reducing postoperative cough and sore throat.

Design: Double-blind, randomized study.

Setting: University-affiliated hospital.
