A Comparative Study of the Effect of Anesthesia Induction with the Use of Four Drug Combinations Including "Propofol," "Etomidate-Propofol," "Thiopental," and "Midazolam-Thiopental" on Hemodynamic Changes during the Insertion of Laryngeal Mask in Eye Surgery.

Background: This study aimed to compare the efficacies of four anesthetic induction drugs (thiopental, propofol, midazolam-thiopental, and etomidate-propofol) on cardiovascular response during laryngeal mask airway (LMA) placement in eye surgery.

Materials And Methods: The present clinical trial study included 128 patients who were candidates for ophthalmic surgery in four groups. Patients in the first group were given a combination of midazolam (0.
