The treatment varies slightly for different causes of respiratory burns. In general, the first step is to keep the airway open, and to give timely tracheal intubation and tracheotomy to keep the airway open according to clinical experience, clinical manifestations, and clinical conditions. If the patient is struggling to breathe, showing hypoxemia or carbon dioxide retention, mechanical ventilation should be given in time, airway nebulization and humidification should be given, airway secretions should be cleared in time, and anti-inflammatory drugs and large amount of glucocorticoids should be given to reduce airway exudation in the lungs and mitigate further damage. Nebulized inhalation can give some bronchodilators to make the bronchial smooth muscle expand and airway dilate, and reduce the airway resistance. At the same time, attention should be paid to systemic treatment and the prevention of infection, as well as the enhancement of nutrition. In general, the treatment of large burns with inhalation injury is relatively easy, but different treatments should be given according to different conditions, different diseases and different causes.
