A comparative study of haemodynamic effects of single-blinded orotracheal intubations with intubating laryngeal mask airway, Macintosh and McGrath video laryngoscopes.

Introduction: The efficacy of an intubation technique is crucial to the success of ventilation therapies. Intubating laryngeal mask airway (ILMA), Macintosh and McGrath techniques are yet to be evaluated thoroughly. Orotracheal intubations with ILMA, McGrath, and Macintosh laryngoscopes are compared based on haemodynamic changes, time taken for intubations, and success rate.
