婴幼儿肺炎链球菌肺炎的肺功能检测及临床特征分析

目的:分析婴幼儿肺炎链球菌肺炎的肺功能情况及临床特征。方法:对72例肺炎链球菌肺炎婴幼儿病例进行回顾性临床分析,并对其中32例婴幼儿肺功能检查结果进行分析总结,肺功能检查采用的是美国森迪公司2600婴幼儿肺功能仪。结果:32例肺炎链球菌肺炎婴幼儿的肺功能检查结果显示,32例通气功能正常,而大气道阻力增高占37.5%(12/32),小气道阻力增高65.6%(21/32),呼吸系统顺应性下降78.1%(25/32)。主要临床症状中发热70.8%(51/72),咳嗽、咳痰100%(72/72),呼吸增快56.9%(41/72)。多可闻及肺部干湿啰音,X线主要表现为肺部斑片影或斑点影,大多数外周血WBC增高、C反应蛋白增高。本组婴儿治疗效果好,全部出院,无一例死亡。结论:本组肺炎链球菌肺炎婴幼儿临床表现以呼吸系统为主,肺功能检查结果多数呈现大气道、小气道阻力增高,阻塞性通气障碍,呼吸系统顺应性下降。肺功能检查可为客观评估肺炎链球菌肺炎婴幼儿病程提供临床依据。

Pulmonary function testing and clinical analysis in infants and young children with pneumonia due to Streptococcus pneumoniae

Objective To analyze the pulmonary function and clinical features in infants and young children with pneumonia due to Streptococcus pneumoniae. Methods In this retrospective study, we reviewed the clinical records in 72 infants and young children with pneumonia due to S.pneumoniae and the outcomes of pulmonary function tests performed using SensorMedics 2600 system in 32 of them. Results The ventilatory function was normal in all the 32 infants. Increased large airway resistance was found in 12, so were inc...
