血钙对老年肺炎患者的严重程度及预后的影响

目的：研究血清钙离子浓度与老年肺炎患者的严重程度及预后的关系。方法：按照脓毒症的诊断标准将入住急诊ICU的老年肺炎患者206例，分为脓毒症组（155例）和非脓毒症组（51例），脓毒症组又按照预后分为存活组（91例）和死亡组（64例）。分别测定血清钙离子浓度、血浆白蛋白、C-反应蛋白（CRP）、血白细胞计数等有关的实验室指标，比较2组指标的差别。结果：脓毒症组中血清钙离子浓度较非脓毒症组降低，CRP、血白细胞计数较非脓毒症组升高（P〈0．01）；亚组分析中，死亡组中血清钙离子浓度较存活组降低（P〈0．01），CRP较存活组升高（P〈0．05），血白细胞计数两组比较无明显差异（P〉0．05）；血清钙离子浓度与血浆白蛋白的浓度呈高度正相关。结论：血清钙离子浓度对判断老年肺炎患者的预后有一定的临床意义。

Influence of serum Calcium with Severity and Prognosis in Elderly Pneumonia Patients

Objective： To investigate the relationship of serum calcium with the severity of disease and prognosis in geriatric patients with pneumonia. Methods： 206 elderly patients with pneumonia admitted to EICU in our hospital were divided into two groups： sepsis group （n=155） and nonsepsis group （n=51）. Patients in sepsis group were divided into two subgroups： survival group （n=91） and death group （n=64）.Serum calcium, plasma albumin, C-reactive protein and leukocyte count were measured. Results： Compared with nonsepsis group, serum calcium was decreased in sepsis group （P〈0.01）. C-reactive protein and leukocyte count in sepsis group were heightened （P〈0.01）. Compared with survival group, serum calcium was much lower in death group （P〈0.01）. C-reactive protein was higher in death group （P〈0.05）. Leukocyte counts were similar in the two subgroups （P〉0.05）. There was a positive correlation between serum calcium and plasma albumin. Conclusion： Serum calcium can be helpful to predict the prognosis of geriatric people with pneumonia.
