1、急诊社区获得性肺炎患者PaCO2水平与预后的关系研究［摘要］目的研宄急诊社区获得性肺炎患者动脉二氧化碳分压水平与预后的关系。方法方便选取该院2016年1月一2017年1月急令CAP患者227例，根据治疗28d病情转归分为存活组、死亡组，根据入院时PaCO2水平高、低、正常分为高水平组、低水平组和正常组，收集患者临床症状、体征、影像等资料，采用单因素和Pearson相关性分析其相关性。结果①死亡组高PaCO2水平和低PaCO2水平患者的构成比例分别为16.84%、38.78%高于存活组的25.81%>61.29%,使用呼吸机患者构成比例为67.74%，高于存活组的9.69%,合并COPD患者占

2、29.03%，多于存活组的5.61%。②根据PaCO2水平分组，低水平组、高水平组PaO2<60mmHg患者构成比例分别为16.84%、53.66%,均高于正常组的3.30%。低水平组呼吸机使用率、死亡率分别为23.16%、18.95%,高水平组分别为26.83%,21.95%,均高于正常组的7.69%、4.40%o③相关性分析显示，高PaCO2水平与预后呈负相关，低PaCO2水平与预后呈正相关，结论PaCO2水平与急诊CAP患者预后相关，是患者死亡的危险因素之一，及早控制PaCO2水平波动可能对改善预后有帮助。［中图分类号］R563［文献标识码］A［文章编号］1674-074205-0037
