Brief summary

In this prospective, randomized, controlled trial, the purpose is to compare Macintosh laryngoscope, EzVision® video laryngoscope, McGrath® video laryngoscope and Storz® video laryngoscope in terms of hemodynamic response associated with intubation in adult patients undergoing Coronary Artery Bypass Surgery (CABG).

Detailed description

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).

Primary

MeasureTime frameDescription
Hemodynamic responseChange from baseline Systolic or Diastolic or mean Blood Pressure at 10 minutesChange from baseline invasive blood pressure

Secondary

MeasureTime frameDescription
Intubation time180 secondsThe duration from when the laryngoscope passes through the teeth until it is withdrawn back to the teeth will be measured.
Visualization of the glottis180 secondsAccording to Cormack Lehane classification four grades (1-4). The higher the grade, the higher the likelihood of difficult intubation.
