Laryngoscopy and Coronary Artery Bypass Graft Surgery

Konya Meram State Hospital112 enrolled

Overview

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).

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).

Outcomes

Primary Outcomes

Hemodynamic response

Change from baseline invasive blood pressure

Time frame: Change from baseline Systolic or Diastolic or mean Blood Pressure at 10 minutes

Hemodynamic response

Change from baseline heart rate

Time frame: Change from baseline heart rate at 10 minutes

Secondary Outcomes

Intubation time

The duration from when the laryngoscope passes through the teeth until it is withdrawn back to the teeth will be measured.

Time frame: 180 seconds

Visualization of the glottis

According to Cormack Lehane classification four grades (1-4). The higher the grade, the higher the likelihood of difficult intubation.

Time frame: 180 seconds
