Brief Summary

Ultrasound has become an essential tool for the daily work of any doctor, but in certain specialties such as Anaesthesiology, its use has greatly increased the safety offered to patients throughout the perioperative period, either to perform nerve blocks, for vascular access, intraoperative hemodynamic management or any other use that allows increasing quality of care.

  5 minutes

Secondary Outcomes (6)

• Modified Mallampati Score Class I: Soft palate, uvula, fauces, pillars visible. Class II: Soft palate, major part of uvula, fauces visible. Class III: Soft palate, base of uvula visible. Class IV: Only hard palate visible.

  1minute

• Thyromental distance measured from the thyroid notch to the tip of the jaw with the head extended

  1minute

• Sternomental distance the distance from the suprasternal notch to the mentum and is measured with the head fully extended on the neck and the mouth closed

  1minute

• Interincisor distance DIstance in centimeters between fornt incisors

  1minute

• Upper Lip Bite Test upper lip bite criteria-class I = lower incisors can bite the upper lip above the vermilion line, class II = lower incisors can bite the upper lip below the vermilion line, and class III = lower incisors cannot bite the upper lip
