Study DesignA retrospective study.PurposeTo explore the risk factors for reintubation after airway obstruction following anterior cervical surgery.Study BackgroundAnterior cervical surgery is an effective surgical therapy for cervical spine disorders. As the anterior approach is adopted more frequently, some rare postoperative complications come under the spotlight, among which, airway obstruction is extremely detrimental. However, the risk factors and the pathogenesis of the airway obstruction still remain unknown. Therefore, finding out the incidence rate and the risk factors of airway obstruction after anterior cervical surgery weighs significantly on preventing airway obstruction.MethodsWe retrospectively analyzed the history and follow-up data of 774 patients who underwent anterior cervical surgery during January 2007 and June 2016. The patients were divided into two groups according to the occurrence of airway obstruction complication. Patients' age, sex, smoking history, drinking history, the presence of diabetes, body mass index (BMI), course of disease, surgical method, the location of the surgical segment, operation duration and the number of surgical segments were recorded and analyzed. Univariate analysis was conducted for the foregoing factors which might associate with concurrent airway obstruction, to screen out statistically significant factors, followed by a multivariate logistic regression analysis to analyze the relationship between these factors and the incidence rate of reintubation for airway obstruction after anterior cervical surgery.Results14 of 744 patients developed postoperative airway obstruction followed by reintubation, which makes the incidence rate of 1.81% (14/774) for patients having airway obstruction after anterior cervical surgery. Among the 14 patients, 12 (85.7%) developed airway obstruction within 48 h after surgery, and 2 (14.3%) postoperative showed delayed airway obstruction in 9-11d after surgery. All of them had reintubation. The results of univariate analysis showed that there were statistically significant differences in age, smoking history, body mass index (BMI), surgical method, the location of the surgical segment, operation duration and the number of surgical segments between the two groups (P < 0.05). Multivariate logistic regression analysis showed that age (OR = 2.038, 95% CI = 1.045-4.012), smoking (OR = 1.502, 95% CI = 1.012-2.375), BMI (OR = (OR = 1.807, 95% CI = 1.126-2.842), operation duration (OR = 2.503, 95% CI = 1.580-3.966), surgical method (OR = 3.386, 95% CI = 1.036-3.625), the location of the surgical segment (OR = 2.391, 95% CI = 1.085-5.159) and the number of surgical segments (OR = 2.512, 95% CI = 1.564-3.768) were the risk factors for airway obstruction and reintubation after anterior cervical surgery (P < 0.05).ConclusionsAge, smoking, obesity, the number of surgical segments, surgical method and surgical segment location are the important factors which may induce airway obstruction after anterior cervical surgery and therefore led to the decision of reintubations.Copyright © 2017 IJS Publishing Group Ltd.
