纤维支气管镜在吸入性肺炎患者治疗中的应用价值研究

Application of electronic bronchoscope in aspiration-induced pulmonary infection

目的探讨支气管镜在吸入性肺炎患者治疗中的临床应用价值。方法选择烟台市莱阳中心医院2015年4月至2017年4月收治吸入性肺炎患者86例为观察对象，采用随机数字表法分为两组，每组43例。对照组采用呼吸机支持等常规治疗，观察组在对照组基础上应用纤维支气管镜检查及气道灌洗治疗。比较两组呼吸机治疗时间、吸氧时间、再插管率、救治成功率以及拔管时简化肺部感染评分。结果治疗后，观察组简化肺部感染评分总分为（2.1±0.2）分，显著优于对照组的（6.4±0.3）分（t＝78.204，P〈0.01）；观察组呼吸机治疗时间、吸氧治疗时间分别为（2.1±0.2）d、（5.5±0.1）d，均短于对照组的（3.3±0.4）d、（6.2±0.3）d，两组差异均有统计学意义（t＝17.595、14.516，均P〈0.01）；观察组再插管率低于对照组，差异有统计学意义（χ2＝63.810，P〈0.01）；救治成功率高于对照组，差异有统计学意义（χ2＝16.827，P〈0.01）。结论吸入性肺炎患者行纤维支气管镜治疗，可显著改善患者肺部感染症状，缩短呼吸机治疗时间，提高临床疗效。

ObjectiveTo evaluate the clinical value of electronic bronchoscopy in the treatment of patients with aspiration pneumonia.Methods86 patients with aspiration pneumonia were selected from April 2015 to April 2017 in Laiyang Central Hospital of Yantai, and they were randomly divided into two groups according to the digital table, with 43 cases in each group.The control group was treated with ventilator support and other conventional treatment.The observation group was treated with fiberoptic bronchoscopy and airway lavage on the basis of the control group.The ventilator treatment time, oxygen treatment time, re-intubation rate, treatment success rate, extubation to simplify the lung infection score were compared between the two groups.ResultsAfter treatment, the score of simplified pulmonary infection in the observation group was （2.1±0.2）points, which was significantly better （6.4±0.3）points of the control group （t=78.204, P〈0.01）. The ventilator treatment time, oxygen treatment time in the observation group were （2.1±0.2）d and（5.5±0.1）d, respectively, which were shorter than those in the control group [（3.3±0.4）d, （6.2±0.3）d]（t=17.595, 14.516, all P〈0.01）. The rate of re-intubation in the observation group was lower than that in the control group, the difference was statistically significant（χ2=63.810, P〈0.01）. And the treatment success rate of the observation group was higher than that of the control group（χ2=16.827, P〈0.01）.ConclusionPulmonary bronchoscopy can improve the symptoms of lung infection in patients with aspiration pneumonia, shorten the time of ventilator treatment and improve the clinical treatment effect.
