    Abstract

    The difficulty in achieving airway patency varies with anatomic and acquired individual patient factors. Thus performing an airway assessment preoperatively in identifying a patient for a potentially difficult intubation is of pivotal importance for the anaesthesiologist. Initially single preoperative airway assessment tests like mouth opening or Inter incisor gap (IIG), Head and neck movement (HNM), Modified mallampatti test (MMT), were used to predict difficult airway. A standard general anesthesia protocol was followed for all cases. All patients received premedication, inj midazolam 0.02 mg/kg, inj glycopyrrolate 0.01mg/kg and inj fentanyl 2 μg/kg intravenously, after attaching standard monitors. After preoxygenation with 100% O2 in each patient, anesthesia was induced with 5-7mg/kg of thiopentone sodium and 0.9 mg/kg of Rocuronium given intravenously to facilitate tracheal intubation after ensuring mask ventilation. Out of 212(81.53%) subjects with RHTMD less than 23.5cm, 5(1.92%) belonged to difficult intubation group. RHTMD more than 23.5cm was there in 48(18.4%) subjects and among them 34(13.07%) had difficult intubation and this is statistically significant with p value 0.001.
