目的探讨床边电子支气管镜肺泡灌洗在ICU肺部感染患者中的应用效果。方法选取2018年 5月至2020年8月我院ICU收治的肺部感染患者160例为研究对象，采用随机数字法分为对照组和观察组，每组80例。对照组患者给予常规内科治疗，观察组患者在对照组患者治疗的基础上给予床旁电子支气管镜肺泡灌洗治疗，比较两组患者的治疗效果、症状缓解情况、血气分析以及住院相关指标。结果观察组患者的治疗总有效率(92.50%)明显高于对照组(81.25%)，差异有统计学意义(P＜0.05)。观察组患者的体温恢复时间、咳嗽消失时间、咳痰消失时间、肺部湿啰音消失时间明显短于对照组，差异有统计学意义(P＜0.05)。治疗前，两组患者的动脉血氧分压(PaO2)、动脉血二氧化碳分压(PaCO2)、动脉血氧饱和度(SaO2)比较，差异均无统计学意义(P＞0.05)；治疗7 d后，观察组患者的PaO2、SaO2明显高于对照组，PaCO2明显低于对照组，差异有统计学意义(P＜0.05)。观察组患者的机械通气时间、抗菌药物使用时间、住ICU治疗时间明显短于对照组，差异有统计学意义(P＜0.05)。结论应用床边电子支气管镜肺泡灌洗治疗ICU肺部感染患者效果显著，可更快地缓解患者的临床症状，改善患者的血气指标，促进康复，值得推广应用。

ObjectiveTo explore the application effect of bedside electronic bronchoscopy alveolar lavage in ICU hospitalized patients with pulmonary infection. MethodsA total of 160 patients with pulmonary infection admitted to ICU in our hospital from May 2018 to August 2020 were selected as the research objects, and they were divided into control group and observation group by the random number method, with 80 cases in each group. The control group was given routine medical treatment, based on which the patients in the observation group were given bedside electronic bronchoscopy alveolar lavage. The therapeutic effect, symptom relief, pulmonary function and hospitality-related indexes were compared between the two groups. ResultsThe total effective rate of the observation group (92.50%) was significantly higher than that of the control group (81.25%), with a statistically significant difference (P＜0.05). The observation group yielded shorter time of body temperature to restore, cough disappear, sputum disappear, and pulmonary moist rale disappear as compared with the control group, with statistically significant differences (P＜0.05). Before treatment, there were no statistically significant differences in the levels of arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2) and arterial oxygen saturation (SaO2) between the two groups (P＞0.05). After 7 days of treatment, the observation group yielded higher PaO2 and SaO2, whereas lower PaCO2 as compared with the control group, with statistically significant differences (P＜0.05). The time of mechanical ventilation, antibiotics use and ICU hospitalization in the observation group were significantly shorter than those in the control group, with statistically significant differences (P＜0.05). ConclusionThe application of bedside electronic bronchoscopy alveolar lavage in the treatment of ICU hospitalized patients with pulmonary infection has a significant effect, which can quickly alleviate the symptoms, improve pulmonary function in patients, and thus promote recovery. It is worthy of promotion and application.
