The AirView Study: Comparison of Intubation Conditions and Ease between the Airtraq-AirView and the King Vision

الملخص EN

We conducted a study assessing the quality and speed of intubation between the Airtraq with its new iPhone AirView app and the King Vision in a manikin.

The primary endpoint was reduction of time needed for intubation.

Secondary endpoints included times necessary for intubation.

30 anaesthetists randomly performed 3 intubations with each device on a difficult airway manikin.

Participants had a professional experience of 12 years: 60.0% possessed the Airtraq in their hospital, 46.7% the King Vision, and 20.0% both.

Median time difference [IQR] to identify glottis (1.1 [−1.3; 3.9] P = 0.019 ), for tube insertion (2.1 [−2.6; 9.4] P = 0.002 ) and lung ventilation (2.8 [−2.4; 11.5] P = 0.001 ), was shorter with the Airtraq-AirView.

Median time for glottis visualization was significantly shorter with the Airtraq-AirView (5.3 [4.0; 8.4] versus 6.4 [4.6; 9.1]).

Cormack Lehane before intubation was better with the King Vision ( P = 0.03 ); no difference was noted during intubation, for subjective device insertion or quality of epiglottis visualisation.

Assessment of tracheal tube insertion was better with the Airtraq-AirView.

The Airtraq-AirView allows faster identification of the landmarks and intubation in a difficult airway manikin, while clinical relevance remains to be studied.

Anaesthetists assessed the intubation better with the Airtraq-AirView.
