Brief Summary: Airwayassessment before any type of anaesthesia is mandatory. Failure to maintain apatent airway after induction of anaesthesia leads to irrevocable catastrophicsequelae such as brain damage or death. Maintaining a patent airway isessential for adequate oxygenation and ventilation and failure to do so, evenfor a brief period of time, can be life threatening that significantlyincreases the morbidity and mortality of general anaesthesia. Ability toventilate the patient with bag and mask is extremely important in theunfortunate scenario of inability to intubate. We find that intubation may beeasy even though mask ventilation is difficult. There are many bed side teststo assess difficult airway and mask ventilation which are easy to perform andneed no special equipment. But all these tests have limitations and no singleone is complete. No single airway test can provide a high index of sensitivityand specificity for prediction of difficult airway. Therefore, it has to be acombination of multiple tests.

Theprimary aim of this study is to evaluate acromio-axillo-suprasternal notchindex, upper lip bite test and ratio of height to thyromental distance forprediction of difficult mask ventilation and difficult intubation.
