本文报告50例肺炎并发胸膜渗出病例。制定了一个区分单纯性和复杂性胸膜渗出标准:(1)胸水pH<7.2;(2)或糖<40mg/dl;(3)胸片示脏器移位;(4)或肺组织被压缩;(5)细菌学检查阳性。用此标准作为评分方法,将50例病人分成两组,然后对两组患儿的治疗、病程和预后进行比较,发现两组间有明显差异。提示本文评分方法对选择肺炎后胸膜渗出的治疗方法,预测病儿病程及预后有一定帮助。 This article reports 50 cases of pneumonia complicated with pleural effusion.

Using this standard as a scoring method, 50 patients were divided into two groups, and then the treatment, course and prognosis of the two groups were compared and found significant differences between the two groups.
