Brief Summary

In the "PrediSuisse" research project, the investigators aim to create a reliable, reproducible, ultra-portable and radiation-free automatized software, able to identify automatically collected features, facial characteristics, and range of movements, to predict intubation difficulty. The software will generate a difficulty intubation score tailored to three commercially available videolaryngoscopes with different type of blades, corresponding to the predicted endotracheal intubation difficulty while providing the anaesthesiologist a reliable and non-subjective tool to assess individual patient's risks with regards to airway management.

Conditions

Anesthesia; Intubation; Difficult or Failed; Airway Complication of Anesthesia

Keywords

Intubation; difficult airway; videolaryngoscopy

Outcome Measures

Primary Outcomes (1)

• Software creation

  The primary outcome is to create a reliable, reproducible, ultra-portable and radiation-free automated software, capable of identifying automatically collected features such as facial characteristics, mouth opening, range of motion while moving the neck and thyromental distance to predict intubation difficulty. The identification of the difficult intubation score will be compared by the one goven independantly by three airway experts.
