探讨纤维支气管镜治疗重症肺部感染合并肺不张患者的效果。

选取西宁市第三人民医院在2016年3月至2018年3月收治的重症肺部感染合并肺不张患者72例，进行回顾性研究。依照随机数字表法实施分为2组，每组36例。36例重症肺部感染合并肺不张患者采用常规治疗作为A组；在此基础之上采用纤维支气管镜治疗的36例重症肺部感染合并肺不张患者作为B组。A组男性27例，女性9例；年龄44~65岁，平均年龄(54.12±19.57)岁。B组男性26例，女性10例；年龄45~64岁，平均年龄(54.94±18.58)岁。观察比较两组的血气分析指标，PCT、CRP、血浆内脂素指标，疗效及临床康复时间。

B组患者在治疗后其各临床症状康复时间短于A组，B组治疗后PCT、CRP、血浆内脂素均低于A组，B组SaO₂、PaO₂、OI均高于A组，且Lac低于A组(P<0.05)。

对于重症肺部感染合并肺不张患者而言，纤维支气管镜可以在直视下观察患者的气管黏膜水肿、渗出、充血及分泌物的情况，能尽可能地将气道分泌物吸出，从而疏通支气管、改善患者呼吸功能，并开展病原菌培植与药敏试验，针对性地应用抗生素，比常规的治疗其效果更为良好，可推广。

To explore the effect of fiberoptic bronchoscopy in the treatment of patients with severe pulmonary infection complicated with atelectasis.

A retrospective study of 72 patients with severe pulmonary infection and atelectasis admitted to the Third People’s Hospital of Xining City from March 2016 to March 2018 was conducted. According to the random number table method, they were divided into 2 groups, each with 36 cases. Thirty-six patients with severe pulmonary infection and atelectasis were treated as group A. On this basis, 36 patients with severe pulmonary infection complicated with atelectasis treated by fiberoptic bronchoscopy were used as group B. In group A, there were 27 males and 9 females; they were 44-65 years old, with an average age of (54.12 ± 19.57) years old. In group B, there were 26 males and 10 females; they were 45-64 years old, with an average age of (54.94±18.58) years. We observed and compared the blood gas analysis indexes of the two groups, PCT, CRP, plasma visfatin indexes, curative effect and clinical recovery time.

After treatment, the recovery time of each clinical symptom in group B was shorter than that in group A. After treatment in group B, PCT, CRP, and plasma visfatin were lower than those in group A, and SaO₂, PaO₂ and OI in group B were higher than those in group A. Lac was lower than that of group A (P<0.05).

For patients with severe pulmonary infection and atelectasis, fiberoptic bronchoscopy can be used to observe the patientcopy can monary infection and atelectasis, fiberoptic bronchoscopy can in group A. Lac to suck out the airway secretions as much as possible, so as to dredge the bronchus, improve the respiratory function of patients, and carry out pathogenic bacteria cultivation and drug sensitivity test, and further targeted application of antibiotics. Therefore, the effect is better than conventional treatment, and it can be promoted.
