Airway Assessment by Comparing Clinical Parameters and Usg Parameters in Correlation With Cormack-Lehane Grade: A Prospective Observational Study

Introduction: Airway assessment before surgery is important for anesthesiologist's to predict difficult intubation. This assessment helps to identify a difficult airway, allowing time for adequate preparation, such as selecting the right equipment and technique. Incapability to sustain a patent airway results in insufficient ventilation and oxygenation leading to hypoxic brain damage and death. Recently Ultra sonogram (USG) gained importance in accurate prediction of difficult airway and has potential to become 1st line non- invasive airway assessment tool in future. Aim: To compare the clinical parameters and USG parameters of airway assessment in predicting Cormack –Lehane grading in patients undergoing elective surgery under general anaesthesia.
