老年下呼吸道感染的预后相干因素研究

目的探讨老年下呼吸道感染的预后相干因素。方法选取101例老年下呼吸道感染患者，分为存活组和死亡组。对两组患者的SIRS评分及各种生化指标及血标本检查结果的均值进行比较，找出与预后最相干的因素。结果年龄、血浆cTnT的水平和SIRS评分均与临床结局呈负相关关系，即年龄越大、血浆cTnT水平越高以及SIRS评分越高的患者，其临床结局越差。结论cTnT水平、SIRS评分及患者的年龄可作为监测老年下呼吸道感染患者预后的主要指标。

Study of the Prognosis Relevant Factor on Geriatric Lower Respiratory Infection

Objective To discuss the prognosis relevant factor of geriatric lower respiratory infection. Methods 101 cases of geriatric lower respiratory infection were divided into survival group and death group. From the comparison of the two groups of patients with SIRS score, various biochemical parameters and blood samples test results, the most relevant factors of prognosis were found out. Results Age, the levels of plasma cTnT and SIRS score were negatively correlated with clinical outcome. The greater the age, the higher the level of plasma cTnT was, the higher the SIRS score, the poorer the clinical outcome was. Conclusion The level of cTnT, SIRS score and age of patient can be used as the main indexes to monitor the prognosis of geriatric lower respiratory infection.
