FERNANDEZ RAMOS, Humberto; PIAS SOLIS, Sarah  and  OCHA VARELA, Selkys M. Correspondence between predictive test of difficult airway and directlaryngoscopy. AMC [online]. 2009, vol.13, n.3. ISSN 1025-0255.

Background: One of the anesthesiologist's responsibilities is to establish and to keep permeable the airway in any clinical situation that involves a commitment (anesthesia, urgencies, resuscitation, etc). The basic principle to attain it is the systematic valuation of the airway and the recognition of the possible difficulties. Objective: To establish the correspondence among the predictive test of difficult airway and the direct rigid laryngoscopy. Method: An analytic cross-sectional study was carried out in patients that were subjected to a kind of surgery that required endotracheal general anesthesia, from January 2007 to September 2007, at the Clinical-Surgical Educational Provincial Hospital “Manuel Ascunce Domenech”. Of an universe of three hundred ninety eight patients, the sample was constituted by one-hundred eighty that were intervened in an elective and urgent way, with administration of this anesthesia. Results: Most didn't present clinical entity associated to the airway, and in those that it existed, obesity and Diabetes Mellitus with more frequency were found. Conclusions: The predictive test of more sensibility was the oral opening. The ones of more specificity was the atlanto-occipital extension, the oral opening and Mallampati. The best predictor in a difficult laryngoscopy belonged to the oral opening. The best predictors for the identification of an easy laryngoscopy, were the oral opening, Mallampati, thyromental distance and atlanto-occipital extension.
