Airtraq requires less forces than DL and other VL

European Journal of Anaesthesiology, T. Gaszynski. Medical University of Lodz, Poland

The objective of this study was to measure the pressure created by different intubation devices on the tongue during endotracheal intubation attempts in the mannequin model . Fourteen specialists and 20 anesthesiologists in training.

Pressure created on the tongue was highest when the Macintosh blade was used and was more than five times higher than with AirTraq and Pentax AWS (P<0.05). When comparing the Pentax AWS and AirTraq, there was no statistical difference (P>0.05).
