Re-evaluation of Blind Intubation Through the Air-Q Intubating Laryngeal Airway

Blind Tracheal Intubation Through the Air-Q Intubating Laryngeal Airway in Pediatric Patients. Re-evaluation. A Randomized Controlled Trial.

To compare the success rate of blind technique with correction manoeuvres versus fiber optic- guided Intubation through the air Q laryngeal airway in pediatric patients

A prior G-power analysis was done to estimate the sample size. The primary outcome of this study was the first trial success rate. Using fibre exact test and assuming alpha (type I error) = 0.05 and beta (type II error) = 0.2 (power =80%), 58 patients per group would be sufficient to detect a difference 10 % in success rate among the groups. A drop out 10% of cases was expected; therefore 63 patients were required in each group to detect the difference.
