Effects of C-MAC Videolaryngoscope, McGRATH Videolaryngoscope and Macintosh Direct Laryngoscope on Intraocular Pressure and Hemodynamics; a Randomized, Double-blind Clinical Trial

The maintenance of airway opened is one of the main responsibility of the anesthetist. Intubation procedure during anesthesia application benefits such as airway opening, airway and breathing control, aspiration hazard, respiratory effort and dead space reduction, surgical comfort and airway control during resuscitation. Laryngoscopy and tracheal intubation increases in heart rate, blood pressure and the intraocular pressure. The sympathetic-adrenal activity caused by the stimulation of the laryngeal and tracheal tissues is responsible for these negative effects. Endotracheal intubation with videolaryngoscopy is an alternative method used in airway management. Laryngoscopy and tracheal intubation under general anesthesia and laryngeal mask and airway control techniques cause different hemodynamic and catecholamine levels.
