Tracheal intubation can be associated with minor complications such as broken teeth or lacerations of the tissues of the upper airway. It can also be associated with potentially fatal complications such as pulmonary aspiration of stomach contents which can result in a severe and sometimes fatal chemical aspiration pneumonitis, or unrecognized intubation of the esophagus which can lead to potentially fatal anoxia. Because of this, the potential for difficulty or complications due to the presence of unusual airway anatomy or other uncontrolled variables is carefully evaluated before undertaking tracheal intubation. Alternative strategies for securing the airway must always be readily available. The present study was planned in Department of Anesthesia, Patna Medical College and Hospital, Patna, Bihar. The study was conducted from February 2013 to January 2014. Total 100 cases scheduled for elective surgery under general anaesthesia requiring tracheal intubation were included in the present study. The data generated from the present study concludes that there are differences in anatomical measurements commonly used to predict a difficult airway between the Indian and non-Indian population. This implies that standard threshold values for predicting a difficult airway may not apply in the Indian population. Airway management remains an important challenge in the contemporary practice of anaesthesia and preoperative airway assessment facilitates appropriate preparation when difficulty with intubation or ventilation is anticipated prior to induction of anaesthesia. Direct laryngoscopy is the gold standard for tracheal intubation. There is no single definition of difficult intubation. Difficult glottic view on direct laryngoscopy is the most common cause of difficult intubation. Difficult laryngoscopy, where in, it is not possible to visualize any portion of the vocal cords after multiple attempts at conventional laryngoscopy.
