Brief Summary: Unanticipated difficultendotracheal intubation remains a challenge in anaesthesia. There are manyparameters to predict difficult endotracheal intubation. By combining severalparameters which predicting difficult endotracheal intubation, diagnostic accuracyof difficult endotracheal intubation can be improved. Ultrasonography being a non-invasive andinexpensive method, we can use it for measuring tongue thickness which is apredictor of difficult endotracheal intubation. In this study we will useMallampati test, Sternomental distance, thyromental distance and ultrasoundguided tongue thickness measurement to evaluate patientâ€™s airway and these willcorrelate with Cormack lehane grade visualised at the time of intubation. Thisprospective and observational study will be done in 165 patients of age between18 and 65 years posted for any type of elective surgery undergoing generalanaesthesia requiring endotracheal intubation. The aim of the study is tocompare the validity of a combination of mallampati test with sternomental andthyromental distance and mallampati test with ultrasound guided tonguethickness to predict difficult endotracheal intubation in adults. In addition,duration of laryngoscopy, duration of intubation and number of attempts ofintubation shall also be noted.
