Indications for tracheotomy mainly include six aspects, namely, prolonged tracheal intubation, sputum not easy to cough up, chest injury, respiratory distress, brain injury, and severe vocal edema. 1. Prolonged tracheal intubation: tracheal intubation generally does not exceed 72 hours, and clinically, it does not exceed 14 days, then tracheotomy is needed. 2. Excessive sputum that is not easy to cough up: If the patient has chronic respiratory disease, more sputum that is not easy to expel, choking, aspiration and other conditions that affect normal breathing, tracheotomy can be considered. 3. Chest injury: If the patient’s chest injury is more serious, chest fracture, affecting normal breathing, tracheotomy can be used to relieve the discomfort. 4. Respiratory difficulties: if the patient has respiratory problems, unable to breathe normally, resulting in decreased oxygen saturation, tracheotomy should be performed in time to improve the respiratory situation. 5. Brain injury: If the patient has craniocerebral injury, such as severe skull fracture or cerebrospinal fluid leakage, etc., resulting in paralysis of the posterior cranial nerves, which causes autonomic respiratory difficulties, tracheotomy can be considered. 6. Severe vocal edema: Tracheotomy is feasible when the patient has edema of the upper part of the vocal folds, and at the same time, there are ring-shaped crusts on the face and neck, and there is respiratory distress. Tracheotomy can relieve the patient’s respiratory distress to a certain extent, but prolonged tracheotomy may also increase the chances of lung infection, and postoperative care should be done.
