Abstract: To summarize the nursing experience of a patient with type A aortic dissection and grade Ⅳ difficult airway who underwent aortic dissection surgery and uvulopalatopharyngoplasty. In view of the patient's hemodynamic disorders,volume disorders and other problems,we maintained hemodynamic stability and volume dynamic balance. For acute respiratory insufficiency,individualized lung protective ventilation measures were adopted to prevent ventilator-associated pneumonia. According to the nursing difficulties and emphases of the airway with grade Ⅳ difficulty after aortic dissection,emergency artificial airway preplan was established to prevent unplanned extubation and throat bleeding,and sequential tracheal intubation extubation was implemented. The patient was given a risk hierarchy based on his high risk of delirium,early stage activities were enhanced. After 31 days of intensive care,the patient recovered well and was discharged.

Key words: Type A Aortic Dissection, Airway Management, Uvulopalatopharyngoplasty, Emergency Nursing
