A paralyzed patient wearing a tracheotomy tube and going home without suctioning may result in sputum clogging the tube, causing the patient to asphyxiate. Most paralyzed patients require tracheotomy intubation, as well as regular suctioning, as the patient is unable to expel sputum normally. The volume of sputum in paralyzed patients is larger every day. If sputum is not aspirated in time, it cannot be discharged normally and becomes more viscous, clogging the tracheal tube, which may lead to asphyxiation and, in severe cases, death. Tracheotomy of paralyzed patients, after going home must pay attention to strengthen the care of the cannula, regular sputum suction treatment, if necessary, but also for nebulization treatment, to ensure that sputum dilution, conducive to sputum suction, with respiratory tract infections should be given to the anti-infective treatment. After paralyzed patients go home, they should carry out the care of tracheal tube under the guidance of professional medical personnel to avoid asphyxiation.
