Introduction: Respiratory complications are quite common occurrence during surgery. It can lead to sudden death during surgery and as it occurs due to anaesthesia, respiratory complication can occur in any surgery. Due to application of general anaesthesia, physiological or mechanical ventilation is disrupted which is the main cause of respiratory complications. The four major principles to be followed while managing the airway are to ensure that if the airway tract is patent, if any advanced management of the airway is indicated, confirm the device placement in the airway tube, if the tube is secure and the confirmation of the device placement is checked frequently. Aims and Objectives: To evaluate the occurrence of airway complication during surgery and to find out the effective scoring system for assessment of airway complication. Materials and Methods: This retrospective study was conducted with 90 patients who were evaluated demographic characteristics, characteristics of patients’ general health, data regarding surgery, data regarding anaesthesia applied during surgery and data regarding management of patients with airway difficulty. The conditions that are considered to be the complication of airway are sudden need for airway device, hypoxemia, esophageal intubation, difficult airway management, ventilator associated complication, insufficient mouth opening, misposition of supraglottic airway devices, tachycardia and hypertension. Results: The study found that most of the surgeries were general surgery constituting about 28.8% followed by ENT surgeries (27.77%). The main findings of this study were that the scoring systems Ventilation score and Cormack-Lehane, were found to be significant in assessing the probability of complication during surgery due to general anaesthesia. Conclusion: The study concluded that there is significant airway associated complications during surgery and Cormack-Lehane and Ventilation score are the most effective scoring system.
