全身炎症反应综合征患者血浆乳酸水平与炎症反应的相关性研究

目的研究全身炎症反应综合征(SIRS)患者急性期反应以及血浆乳酸水平与炎症反应标志物C-反应蛋白(CRP)、内毒素浓度的相关性。方法符合SIRS诊断32例于入院时、入院后第2和5天早晨空腹抽取肘静脉血8ml,应用氧化酶法在日立全自动生化分析仪上进行测定血浆乳酸,速率散射免疫比浊法测定CRP和基质偶氮显色鲎试验测定法测定内毒素浓度,并设健康对照组。结果血浆乳酸水平、CRP水平和内毒素浓度在时相监测点均同步升高,与对照组比较差异有统计学意义(P均0.01);血浆乳酸水平与CRP浓度、内毒素含量呈正相关(P0.01);器官功能不全组患者血浆乳酸水平、CRP水平和内毒素浓度高于器官功能正常组患者(P0.05)。结论 SIRS患者炎症急性期反应时,具有直接或间接作用使血浆乳酸水平增高,同时乳酸水平增高也有可能加重炎症反应。因此,监测SIRS患者血浆乳酸水平,能反映炎症反应的程度,是判断治疗效果和预后的有效措施。

Correlative study between plasma lactate concentration and Inflammatory reaction In patients with systemic Inflammatory response syndrome

Objective To investigate the relationship between concentration of plasma lactate,serum C-reactive protein(CRP) and plasma endotoxin in patients with systemic inflammatory response syndrome(SIRS).Methods A total of 32 patients with confirmed diagnosis of SIRS were enrolled in this study.Venous blood samples were collected on the mornings of 1st,2nd and 5th d after admission.Plasma lactate was determined by enzymatic measurement.Serum CRP and plasma endotoxin were also measured at the same monitoring sites.B...
