Tracheal intubation in patients with cerebral infarction means that the patient’s respiratory function is affected, which usually indicates that the patient’s condition is more serious, and common causes include brainstem infarction, crushing pneumonia, and involuntary respiration. Endotracheal intubation usually means tracheal intubation operation, which is applicable to respiratory muscle weakness, airway obstruction, respiratory depression and other conditions. 1. Brainstem infarction: when there is a large infarction of the brainstem, the respiratory center is inhibited, and then tracheal intubation is needed to maintain the patient’s respiration through mechanical ventilation. 2. Accumulative pneumonia: patients with cerebral infarction lose the ability of self-movement due to severe impairment of limb function and cognitive function, and prolonged bed rest leads to lung infection. As sputum is not easy to be extracted, sputum needs to be suctioned through endotracheal tube and assisted ventilation. 3. Involuntary respiration: If there is no voluntary respiration, tracheal intubation will be given and mechanical ventilation will be given to maintain life. There are many other reasons for tracheal intubation in patients with cerebral infarction, so it is recommended to consult your doctor.
