目的分析间质性肺炎患儿的临床病情评估中肺功能变化的诊断价值。方法选择我院2011年到2012年间60例间质性肺炎患儿(对照组)与50例身体处于健康状态的婴儿(观察组)的临床资料,分别测定两组婴儿的肺功能情况并且将测定结果进行比较,对间质性肺炎患儿不同指标以及潮气呼吸容量环之间的变化进行细致的观察,将间质性肺炎患者的住院时间以及临床疾病的诊断与肺功能测定指标互相结合分析。结果将两组婴幼儿的肺功能各项指标进行比较,对照组的婴幼儿在间质性肺炎急性期时的潮气呼吸容量环出现较大的变化,并且上升支斜率患儿的呼气降低,高峰提早发生,降支以波谷形式呈现并且往容器轴内凹。对照组的婴幼儿呼吸系统阻碍、呼吸流速的比值、潮气呼气峰流速以及呼吸频率各方面的监测都高于观察组婴幼儿的指标。对婴幼儿各项指标的详细分析均发现患儿的住院时间、临床疾病评估与PF/V25有着正相关的关系(r=0.601、0.312,P<0.05),而临床疾病的评估与Crs/kg有着负相关的关系(r=-0.311,P<0.05)。结论婴幼儿在患上急性间质性肺炎后检测肺功能各项指标具体体现在通气功能限制性障碍、呼吸系统阻塞等方面,监测患儿的肺功能各项指标能够为间质性肺炎临床疾病评估提供了一定的基础。
Objective To analyze the diagnostic value of pulmonary function in the assessment of clinical condition in children with interstitial pneumonia. Methods The clinical data of 60 children with interstitial pneumonia (control group) and 50 healthy infants (observation group) from 2011 to 2012 in our hospital were collected. The lung function of the two groups of infants was measured and the lung function The results were compared to different indicators of children with interstitial pneumonia and changes in the relationship between moisture and respiratory capacity ring careful observation will be interstitial pneumonia in patients with hospitalization and clinical disease diagnosis and lung function analysis of indicators combined with each other. Results The indexes of pulmonary function in infants and toddlers were compared. The infants in the control group showed a large change in the moisture respiration capacity at the acute stage of interstitial pneumonia, Peaks occur earlier, with descending branches being trough-shaped and recessed toward the container axis. Infants in the control group, respiratory system obstruction, the ratio of respiratory flow rate, peak expiratory flow rate of breath and respiratory rate in all aspects of monitoring were higher than the observation group infants and young children’s indicators. A detailed analysis of various indicators of infants and young children found that there was a positive correlation between hospitalization duration and clinical disease assessment and PF / V25 (r = 0.601,0.312, P <0.05), while the clinical disease assessment was related to Crs / kg There was a negative correlation (r = -0.311, P <0.05). Conclusion Infants and young children with acute interstitial pneumonia after the test of lung function indicators specifically embodied in restrictive ventilation disorders, respiratory system obstruction and other indicators of monitoring of children with pulmonary function can be interstitial pneumonia clinical disease Evaluation provides a certain basis.
