Abstract:
OBJECTIVE:To research the causes of postintubation vocal cord dyskinesia and its contributing factors.
METHOD:The causes of vocal cord dyskinesia were confirmed by laryngoscope, three-dimensional spiral CT, stroboscope, and the analysis of therapy. The factors relevant to the causes of vocal cord dyskinesia were analysed based on the following elements: (1) the anatomic or pathological condition of patients or the technical skills of anesthetists. (2) emaciated or obese body and neck. (3) the age of patients. (4) the duration of endotracheal tube retention. (5) the types of operations. (6) anesthesia procedure.
RESULT:Among 135 patients, 128 cases (94.81%) manifested arytenoid dislocation, 7 cases (5.19%) vocal cord paralysis. The study showed that the vocal cord dyskinesia associated with anatomic or pathological condition of patients and technical skills of anesthetists (with intubation difficulty) accounted for 76.30%. The patients with relative emaciated body or neck accounted for 90.62% in cases without intubation difficulty. Age had no significant analytical relationship with vocal cord dyskinesia. Prolonged intubation (endotracheal tube retention over 12 hours) was accounted for only 17.64%. The incidence of vocal cord dyskinesia was nearly 0.5% in patients underwent cardio-thoracic surgery, accounting for 59.26% of all the patients.
CONCLUSION:There are two major causes of vocal cord dyskinesia: arytenoid dislocation and vocal cord paralysis, and the rate of vocal cord dyskinesia could be reduced by the improvement of technical skill of anesthetists and/or sufficient attention to the intubation condition of patients.
