Food choking into the lungs usually does not require an incision, after food choking into the lungs, the body will reflexively cough violently to expel the food, if the cough can not completely expel the food, there will be tracheospasm, laryngeal edema, affecting the patient’s breathing, after which it will also cause aspiration pneumonia, lung abscess and other infectious complications of the lungs. At this time, the infection can be controlled with adequate antibiotics, glucocorticoid intravenous drip, and nebulized inhalation to control tracheospasm and laryngeal edema, and then a tracheoscope can be lowered through the nostril, through the pharynx, vocal cords, and then to the trachea, where the food can be sucked out under the tracheoscope, usually without an incision. However, if the patient has severe laryngeal edema, extreme respiratory distress, and is about to suffocate, an emergency incision in the neck is needed to cut the trachea open to help the patient through the difficult time.
