Objective To investigate risk factors of the adverse event during the fiberoptic bronchoscopy in children and to give some related nursing strategies. Methods Eighty cases were enrolled from pediatric department of the first people's hospital of hangzhou, who were performed by bronchoscope from July 2012 to July 2015, and were divided into the observation group and the control group according to whether appeared the adverse event, with 40 patients each, then univariate and multivariate Logistic regression analysis were adopted. Results Univariate logistic regression analy-sis showed that age, basic disease and operation time were the risk factors of the adverse event during the fiberoptic bronchoscopy in children. Multivariate logistic regression analysis showed that age(OR:16.628,95%CI:1.688-163.764), basic disease (OR:9.369,95%CI:1.429-61.412), operation time (OR:15.252,95%CI:1.767-131.676), were independent risk factors of the adverse event during the fiberoptic bronchoscopy in children. Conclusion More attention should be paid to the younger patients with underlying diseases and long operation time, and corresponding nursing measures should be applied to reduce the adverse event when performed by bronchoscope.
