Evaluation of knowledge of the anesthesiologists about the available resources for the approach of difficult airway within

Introduction: Secure the airway is essential for a safe anesthetic practice and it occurs without difficulties in most cases. However, complications resulting from a failure in the approach used for a diffi cult airway are the main causes of morbidity and mortality attributable to anesthesia. In an attempt to prevent its severity, it becomes imperative to try to anticipate the difficulty whenever possible. Reports show incidence of difficult airway in approximately 2% of the general population and the ASA recommends the prior identification and the use of algorithms to address this complication.
