Adult patients requiring endotracheal intubation divided into three groups; standard Airtraq, Nasotracheal Airtraq + styletted endotracheal tube and Airtraq + fiberoptic combination groups.

We enroll lean adult patients requiring endotracheal intubation. Using a sealed envelope technique they divided into three groups; Standard Airtraq and Nasotracheal Airtraq + styletted endotracheal tube and Standard Airtraq + fiberoptic combination. Demographic characteristics and airway management variables such; age, gender, height, weight, ASA status, tooth morphology, tiro mental and sternomental distance were recorded. Insertion times, intubation times and total intubation times with these devices will be recorded. Hemodynamic parameters recorded such as; heart rate will be recorded baseline , after anesthesia, after insertion, just after and then every 2 minutes intervals after intubation. sore throat, hoarseness, dysphasia, bronchospasm were also recorded postoperatively.
