Abstract
Introduction: The incidence of tracheal intubation was reported to be in the range of 0.1-20.2%; this variation was due to the different patient populations and criteria used. Consequently, prediction of difficult intubation relies on various tests and their combinations. Yet, these tests either individually or in combination failed to predict difficult visualization of larynx reliably. So the quest for a new test continues. AASI, a relatively new test, based on surface land mark, has been suggested to reliably predict difficult visualization of larynx.Methodology: A total of 250 adult patients aged 18-60 years, belonging to ASA class 1 and 2 who were candidates undergoing elective surgery under general anaesthesia requiring tracheal intubation were enrolled in this study.Results: Out of 250 patients, 31 patients had DVL in which 21(67.7%) had AASI of >0.5 and 10(32.3%) had AASI of 0.5% and 199 patients had AASI of
