Clinic study on early low does heparin therapy of severe sepsis patient ZHANG Xiao-juan MA Xiao-chun (The First Affiliated Hospital of [ABSTRACT] Objetive:to study early low does heparin therapy severe sepsis influent the clinical result。Methods: the study included 16 patients,radomized group。Control group :management of the patients was carried out according to the guidelines for modern intensive care therapy。Experiment group:received standard heparin continuously including usual therapy。PT,APTT,Platelet count,APACHE-Ⅱ score,the time of patient in ICU,the time of patient in hospital,cure rate and 28 days survival rate were measured at fist day of ICU。Result:①PT,APTT of experiment group was improved,,but PT,APTT of control group almost had no change, Platelet count between two group had no difference;②The time of patients in ICU of experiment group was less than the time of control group(P﹤0.01);③cure rate of experiment group was 81.8%,cure rate of control group was 54.5%;④the time of patients in hospital of experiment group and control group had no difference(P﹥0.05);⑤the 28 day survival rate of experiment group and control group was the same。Conclusion:early low does heparin therapy severe sepsis can reduce patients time of ICU,improve cure rate ,had no bad reaction。 [key word ] severe sepsis heparin anticoagulation 引言 重症感染患者发生器官功能障碍的原因复杂,在早期即可发生血管内皮细胞损伤及凝血系统紊乱,这种紊乱包括促凝活性增加、抗凝活性减少、纤溶系统受抑等。凝血激活伴随纤溶活性下降,纤维蛋白沉积在组织,从而出现组织坏死及多器官功能衰竭。肝素不仅有传统的抗凝作用,还具有抗炎效应。肝素可降低血液中炎性介质(如组胺)的水平并增加组织因子抑制物(TFPI)的释放[1]。肝素对凝血活动的各个环节均有作用,包括抑制凝血酶原转变为凝血酶、抑制凝血酶活性、阻止纤维蛋白原转化为纤维蛋白、防止血小板聚集和破坏等。肝素在DICd 治疗上有肯定的疗效,但重症感染所致凝血系统损伤,肝素是否有效尚不清楚。本文试图在损伤早期应用小剂量肝素干预,观察其对出凝血功能及预后的影响 资料和方法 1.1 临床资料 选择在中国医科大学附属第一医院ICU病房 matory response syndrome ,SIRS)的概念[2],并制定的“脓毒症”的诊断标准。APACHE-Ⅱ评分5-25分 ,有活动性出血的病人除外,有肾衰竭需要血液滤过和透析的病人,有异常凝血史的病人除外。性别不限,年龄18-85岁之间,病人按入ICU的先后顺序邻近的APACHE-Ⅱ评分相同的编为一组,查随机数字表组内入选的病人随机进入对照组和实验组。 1.2 检测指标 1.3 统计学方法 数据均采用( |
