纤维支气管镜在危重症合并重症肺感染中的应用

目的:探讨经纤维支气管镜吸痰结合支气管肺泡灌洗术(BAL)在危重症合并重症肺感染中的应用价值。方法:将84例危重症合并重症肺感染患者随机分为2组,每组42例,治疗组除常规予以抗生素、化痰、湿化气道、营养支持、促进排痰外,均采用纤支镜吸痰结合BAL。对照组予以常规治疗而未使用纤支镜吸痰及BAL,将2组临床疗效、体温、白细胞计数及C反应蛋白进行比较。结果:对照组治疗前后呼吸频率(RR)、心率(HR)、酸碱度(pH)、动脉血氧分压p(O2)]、动脉血二氧化碳分压p(CO2)]、经皮血氧饱和度(SaO2)比较差异无统计学意义(P>0.05);治疗组治疗后RR、HR、pH、p(O2)、p(CO2)、SaO2较治疗前有明显好转,差异均有统计学意义(P<0.05);治疗组与对照组治疗有效率比较差异有统计学意义(P<0.01),治疗一周后治疗组与对照组体温、白细胞计数及C反应蛋白比较差异有统计学意义(P<0.05)。结论:经纤支镜吸痰结合BAL可提高重症肺感染患者的治愈率,是一种安全、简便、及有效的方法,具有推广和应用的价值。

The Application of Bronchoscopy in Critical Patients with Severe Pulmonary Infection

Objective: To evaluate the significance of combined of bronchoscopy with bronchial alveolar lavage (BAL) in critically ill patients with severe pulmonary infection.Methods: Eighty-four critically ill patients with severe pulmonary infection were randomly divided into treatment group and control group (n=42 for each group).Patients were given antibiotics,eliminate sputum,airway humidification,nutritional support and promote expectoration in the conventional treatment group.And all patients were given fiberop...
