Sepsis的概念与译名:内涵重于形式 北京协和医院内科ICU 刘光云,杜斌 Sepsis是重症监护病房中危重病患者死亡的主要原因。由于缺乏特异性治疗措施,根据共识定义与诊断标准进行早期发现与早期诊断,成为降低sepsis病死率的关键。 1992年发表的欧美共识会议标准将sepsis定义为感染引起的全身炎症反应综合征(SIRS)。尽管这一定义受到质疑,但其实质是认为感染引发的过度全身反应(即sepsis)才是引起器官功能障碍甚至死亡的主因[1]。这一概念沿用至今。2001年更新的sepsis诊断标准旨在改进诊断的特异性,但由于缺乏...

大连医科大学重症医学研究所/附属一院重症医学科(116011)李文雯 万献尧   急性呼吸窘迫综合征(ARDS)是严重威胁患者生命的危重症,其临床发病率和病死率均较高。尽管近年来对其发病机制、治疗策略等研究有了很大的进展,但其病死率仍居高不下,可达36%~45%[1],甚至更高。因此,及时正确的诊断与治疗,在临床工作中起着极其重要的作用。 自1967年Ashbaugh等[2]报告了ARDS的病例以来,ARDS便成了基础和临床的研究热点,但尚缺乏统一的临床诊断标准。直至1994年,欧美联席会议(AECC)提出了急性肺损伤(ALI...
