Background: Maintenance of a patent airway is a primary responsibility of anesthesiologists. The difficulty of achieving a patent airway varies with anatomical and other individual factors, and identification of the patient with a difficult airway is vital in planning anesthesia management so that endotracheal intubation and positive pressure ventilation can be achieved safely. Institutional based crossectional study design was conducted using systematic random sampling technique. Regular supervision and follow up was made. Sensitivity, specificity, positive and negative predictive value was calculated to confirm presence of difficulty airway. A total of 184 patients who underwent surgery under general anaesthesia were included into the study. The mandibular protrusion test, the use of stylet, neck mobility and mouth opening < 30 mm are the airway parameters found to the most sensitive tests. The combination of bedside airway parameters to predict difficult airway showed that Mallampati classes III & IV, Mandibular protrusion mouth opening < 30 mm, attempt > 3, and ineffective alternative technique were strongly associated with difficulty airway.
