Primary outcomePrimary: Force Applied and Pressure Distribution Upon the Blade of Laryngoscopes During Tracheal Intubation. — 16; 10; 40; 8 Newton

Summary

Forces applied on soft upper tissues by different laryngoscope blades during direct laryngoscopy and intubation are considered to be major stimuli to cause serious damages to the patients. The aim of this study is to compare the force and pressure applied to soft tissue in order to achieve the same glottis view comparing direct laryngoscopy and videolaryngoscopy in vivo.
