Abstract:
OBJECTIVE:To assess the incidence of postoperative vocal cord immobility in patients following endotracheal intubation underwent general anesthesia.
METHODS:We retrospectively enrolled patients who underwent surgical procedures with endotracheal intubation under general anesthesia from January 2014 to December 2018 in Peking University First Hospital. Demographic and treatment data were obtained for patients with hoarseness and vocal cord fixation. The incidence of postoperative hoarseness and vocal cord fixation were presented and clinical outcomes were further analyzed.
RESULTS:A total of 85 998 patients following tracheal intubation and general anesthesia were enrolled in this study. Hoarseness was observed in 222 (0.26%) patients postoperatively. Sixteen patients (73%) were accomplished with symptoms of choking on water, dysphonia and sore throat. Twenty-nine patients with persistent hoarseness on the third postoperative day needed further treatment by otolaryngologists. Among them, seven patients had pharyngolaryngitis and twenty-two patients (0.026%) were demonstrated postoperative vocal cord immobility. There were seventeen patients (77%) with left-side vocal cord fixation and five patients (23%) with right-side vocal cord fixation. Nine patients were identified with arytenoid dislocation. Seven patients had left vocal cord fixation and two patients had right-side vocal cord fixation. Seven patients were intubated under the guidance of visual laryngoscope. One patient was confirmed difficult airway and intubated with light wand. One patient was inserted with laryngeal mask airway. One patient was suspected to have hoarseness caused by gastric tube before anesthesia. One patient showed simultaneously left recurrent laryngeal nerve abnormality on laryngeal electromyography result. The symptom of hoarseness ranged between 6 and 31 days. Three patients underwent closed reduction under local anesthesia and one patient demonstrated spontaneous recovery. Among the remaining thirteen patients with vocal cord immobility, two patients were demonstrated vocal cord paralysis. Eleven patients underwent neck surgery, thyroid surgery and cardiothoracic surgery and further examinations including laryn-geal electromyography and computed tomography help to determine the diagnosis were not performed. All patients were treated with inhaled corticosteroid conservatively. Five patients had significant improvement of symptom and almost regained normal voice. One patient had slight improvement and sixteen patients were not relieved before discharge.
CONCLUSION:Patients with hoarseness and vocal fold immobility after endotracheal intubation should be treated properly and immediately.
