Which Nostril Should be Used for Nasotracheal Intubation With Airtraq NT®: the Right or Left? A Randomized Clinical Trial

Study Overview
=================
Brief Summary
-----------------
After Ethics committee approval investigators decided to enroll 40 patients ASA I-II, 18-60 years of age undergoing maxillofascial, oral and double chin surgery to determine which nostril is more suitable for nasotracheal intubation with nasotracheal Airtraq. We primay aimed to compare the glottis visualization time, intubation time and total intubation times.

Detailed Description
-----------------
After Ethics committee approval, investigators decided to enroll 40 pateints ASA I-II, 18-60 years of age undergoing maxillofascial, oral and double chin surgery to determine which nostril is more suitable for nasotracheal intubation with nasotracheal Airtraq. In addition is the 90° anti-clockwise rotation of the tip of the tube helpful to insert the tube into the trachea. Patients were randomized into right and the left nostril groups. After standard anesthesia induction with propofol and fentanyl, rocuronium was used for muscle relaxation. Primary aim of this prospective study was to compare the glottis visualization time, intubation time and total intubation times. The Cormack-Lehane grades, the need for optimization, tube adjustment maneuvers, hemodynamic data, occurrence of epistaxis of the patients were recorded during the process.
