[Application strategy and effect of cuffed tracheostomy tube with inner cannula in the treatment of postoperative complications of laryngeal or hypopharyngeal cancer].

Objective: To Investigate the application strategy and effect of cuffed tracheostomy tube with inner cannula in the treatment of postoperative complications of laryngeal and hypopharyngeal cancer. Methods: A total of 60 patients with laryngeal and hypopharyngeal cancer occurred serious postoperative complications, including 31 cases of severe postoperative neck infection, 8 cases of dyspnea, 5 cases of massive hemorrhage and 16 cases of seriously intractable aspiration. The tracheal cannula with inner cannula and outer cuff was immediately worn on these patients and the cuff was inflated. Different treatments were carried out according to different complications. The outer cuffs were inflated for patients with severe neck infections to prevent a large amount of neck secretions inhaled to the trachea. Patients with dyspnea immediately received ventilator-assisted ventilation. For those with massive hemorrhage on the wound, doctors should prevent bleeding and stop bleeding under general anesthesia. Patients with severely coughing should perform eating training to prevent food aspiration. The inner cannula was regularly replaced once a month for all of these patients. Results: Through targeted treatment, the complications of 60 patients with cuffed tracheostomy tube with inner cannula were effectively controlled. After dressing change, the neck wounds of 31 patients with neck infection were shrunk or healed. Finally, all of the patients were replaced with metal tracheal tubes. Eight cases with dyspnea were rescued with the symptomatic and related special treatment, and finally replace by metal tracheal tube. Five cases with massive bleeding in the neck wound were successfully rescued and replaced with metal tracheal cannula. Thirteen patients among 16 cases with intractable aspiration were removed the tracheal cannula and other 3 cases of old and severely ill were replaced with metal tracheal cannula. Conclusions: The cuffed tracheostomy tube with inner cannula is of great value in the treatment of severe postoperative complications of laryngeal or hypopharyngeal cancer. It is strongly recommended that the operators should fully understand and use it reasonably after the operation of laryngeal or hypopharyngeal cancer.
