老年人下呼吸道感染患者实验异常与临床评价

STUDY ON THE RELATIONSHIP BETWEEN LABORATORY DATA AND CLINICAL PRESENTATION IN ELDERLY PATIENTS WITH LOWER RESPIRATORY TRACT INFECTION.

目的探讨老年人下呼吸道感染患者实验室异常和临床的关系，给临床变化判断提供一定依据。方法总结 168例老年人下呼吸道感染患者实验室生化检查结果，以是否有低磷血症把下呼吸道感染患者分为两组（低磷组和非低磷组），比较两组的实验室检查结果、炎症吸收情况及死亡率。结果低磷血症组患者血清钠、钾、钙、总蛋白、白蛋白、胆固醇低于无低磷血症者（ P< 0.05），尿素氮及碳酸氢根高于无低磷血症患者。而且，低磷血症组下呼吸道感染吸收时间稍长于非低磷血症患者，而迁延不愈及死亡率高（ P< 0.05）。结论下呼吸道感染患者实验室检查异常与病情及预后不良有一定关系。

Objective To search for the factors closely associated with the progression and prognosis of lower respiratory tract infection in elderly patients.Methods The laboratory data obtained from 168 aged peoples with lower respiratory tract infection in ward were analyzed.The cases were divided into hypophosphatemia group (52 patients) and without hypophosphatemia group (116 patients)and the difference in laboratory data,the duration for infection resolution and the mortality were compared.Results The level of sodium,kalium,calcium,total protein,albumin and cholesterol in the hypophosphatemia group was lower than that in the without hypophosphatemia group (P<0.05).The resolution of lower respiratory tract infection in the hypophosphatemia group is slower than that in control group(without hypophosphatemia),and the mortality is higher (P<0.05).Conclusions The hypophosphatemia,hypokalium,hyponatremia,hypocholesterol and hypoproteinemia (abnormal laboratory data )can be used as predictors to indicate the severity and the prognosis of the aged patients with lower respiratory tract infection.
