【摘要】:目的分析高血压脑出血患者术后并发肺部感染的病原菌分布,并通过检测患者术后外周血炎症因子水平探寻可用于预测诊断感染的指标。方法分析2014年1月-2016年12月在医院接受高血压脑出血微创手术治疗患者的临床资料,依据术后是否并发肺部感染分为感染组56例及未感染组61例,分别于术后1、3d采集两组患者外周血,检测白介素-10(IL-10)、降钙素原(PCT)、C-反应蛋白(CRP)及肿瘤坏死因子-α(TNF-α);检测两组患者肺功能指标,包括:用力肺活量(FVC)、第一秒用力呼气容积(FEV1)、FEV1/FVC及FEV1%。结果 56例感染组患者呼吸道分泌物中分离出致病菌65株;其中革兰阳性菌36株占55.38%,革兰阴性菌26株占40.00%,真菌3株占4.62%;感染组患者与未感染组患者FVC(2.41±0.18VS 3.15±0.12)、FEV1(1.82±0.22VS 2.23±0.15)、FEV1%(57.11±7.65VS 71.78±8.09)及FEV1/FVC(51.26±8.53VS 66.01±7.89)比较,差异均有统计学意义(P0.05);术后3d,感染组患者与未感染组患者外周血CRP(29.77±6.16 VS20.19±4.92)、PCT(2.31±0.35VS 1.56±0.27)及TNF-α(39.98±7.84VS 22.30±7.22)比较,差异均有统计学意义(P0.05);ROC曲线分析显示,以29.38ng/L为截点值,术后3dTNF-α诊断高血压脑出血术后并发肺部感染的敏感性为85.25%,特异性为91.07%,曲线下面积为0.94,优于CRP及PCT。结论高血压脑出血术后肺部感染的主要病原菌为革兰阳性菌,感染可导致患者肺功能显著降低,术后3d外周血指标对术后肺部感染具有一定预测诊断价值,其中TNF-α的诊断价值较高。
[Abstract]:Objective to analyze the distribution of pathogenic bacteria in postoperative pulmonary infection in patients with hypertensive intracerebral hemorrhage, and to explore the prognostic index of infection by detecting the levels of inflammatory factors in peripheral blood of patients after operation.Methods the clinical data of patients undergoing minimally invasive surgery for hypertensive intracerebral hemorrhage in hospital from January 2014 to December 2016 were analyzed. According to the postoperative pulmonary infection, 56 patients were divided into infected group (n = 56) and non-infected group (n = 61).缁撴灉 56渚嬫劅鏌撶粍鎮h,
