Design outcomes

Primary

MeasureTime frame
To demonstrate that thyromental height has a sensitivity and specificity of more than 75% in predicting a difficult laryngoscopes view.Timepoint: Within 24 hours of surgery and Cormack Lehane grading upon intubation.—

Secondary

MeasureTime frame
To calculate a cut off value for thyromental height. To calculate the positive predictive value, negative predictive value and accuracy of thyromental height in predicting a difficult laryngoscopes view. To calculate the efficacy of thyromental height as a predictor of difficult intubation. Comparison of Thyromental height with other routinely used bedside airway parameters such as Mallampati grade and thyromental distance.Timepoint: in a span of one year—
