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).

| Measure | Description | Time Frame |
|---|---|---|
| Hemodynamic response | Change from baseline invasive blood pressure | Change from baseline Systolic or Diastolic or mean Blood Pressure at 10 minutes |
| Hemodynamic response | Change from baseline heart rate | Change from baseline heart rate at 10 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| Intubation time | The duration from when the laryngoscope passes through the teeth until it is withdrawn back to the teeth will be measured. | 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. |
