Abstract
BACKGROUND
Endotracheal intubation is accomplished for safe airway establishment, anaesthesia and operation in operating room, intensive care unit and emergency room mostly. Therefore, it will be beneficial that we predict and provide against difficult airway. With this view, our study was planned and carried out.
METHODS
For 251 patients with ASA physical status I or II undergoing general aneathesia, the correlation between their age, sex, height, weight, BMI (body mass index), Samsoon & Young classification and laryngoscopic grades by Cormack & Lehane was investigated.
RESULTS
Laryngoscopic grades were correlated significantly with patients' age and Samsoon & Young classification. Endotracheal intubation succeeded all, but, 8 patients (3.2%) were difficultly intubated with cricoid cartilage compression and stylet-using.
CONCLUSIONS
Before intubating the trachea, it is desirable that patient' age, Samsoon & Young classification and the extent of neck's movement are assessed.
