Primary Outcome Measures

Name	Time	Method
Pretracheal fat thickness for intubation complexity	5 minutes	The pretracheal fat at the level of the vocal cords will be evaluated with ultrasound, to discern if a certain thickness is related to a difficult laryngoscopic vision (understood as cormack 3 or 4)
