Brief summary

Virtual experiment : comparing the new method with conventional method of determining the depth of endotracheal intubation.

Detailed description

Effective airway management is the primary concern of the anesthesiologist. The conventional method of determining the insertion length of the endotracheal tube, 21 cm for women and 23 cm for men, shows a high incidence of endobronchial intubations in the analyzed population.The aim of this study is form a new and safe practice habit by passing the endotracheal tube with the balloon just 2 cm below the vocal cords during intubation.
