Endotracheal intubation increased the heart rate and blood pressure in normal patients. Open heart surgery patients are more prone to hemodynamic variability. In addition, they have increased possibility for difficult intubation The heart rate and blood pressure increase impaired the oxygen consumption. This was previously shown that Videolaryngoscopes minimaly effects the vital signs in normal patients. Videolaryngoscopy inreased the rate of success in normal and difficult airway. This study aimed to compare two laryngoscopes regarding hemodynamic parameters and intubation times in coronary bypass surgery.

Aim: Endotracheal intubation increased the heart rate and blood pressure in normal patients. Open heart surgery patients are more prone to hemodynamic variability. In addition, they have increased possibility for difficult intubation The heart rate and blood pressure increase impaired the oxygen consumption.

This study aimed to compare two laryngoscopes regarding hemodynamic parameters and intubation times in coronary bypass surgery.

Material and methods: 50 patients undergoing coronary bypass surgery enrolled in this prospective.randomized study. Demogaphic variables and airway characteristics of patients were recorded. Glottic visulisation and intubation time were recorded. Systolic blood pressure, diastolic blood pressure, mean arterial pressure and heart rate were recorded 2 minutes intervals before intubation, after intubation during 10 minutes.

Inclusion Criteria:

• patients undergoing open heart surgery
• < 18 years of age

Exclusion Criteria:

• emergency
