Hemodynamic Response to Various Laryngoscopes During Tracheal Intubation in CABG Patients

During endotracheal intubation, laryngoscopy can significantly affect hemodynamic responses, including tachycardia and elevated blood pressure, which may be particularly detrimental to individuals with cardiovascular conditions. Various studies have explored the hemodynamic reactions associated with laryngeal stimulation through different intubation devices. Researchers hypothesize that endotracheal intubation using video laryngoscopy will elicit a reduced hemodynamic response compared to traditional (Macintosh) laryngoscopy. In this prospective and randomized clinical study, the purpose is to compare the Macintosh laryngoscope, EzVision® video laryngoscope, McGrath® video laryngoscope and Storz® video laryngoscope concerning haemodynamic response associated with intubation in adult patients undergoing Coronary Artery Bypass Surgery (CABG).
