NEJM:糖皮质激素辅助治疗感染性休克未能降低死亡率

2018-04-12 吴星 环球医学

感染性休克是重症医学科内威胁患者生命的常见疾病。在感染性休克患者的救治中广泛应用氢化可的松。但2018年3月,发表在《N Engl J Med》的一项研究显示,在进行机械通气的感染性休克患者中,持续输注氢化可的松未能降低90天死亡率。

感染性休克是重症医学科内威胁患者生命的常见疾病。在感染性休克患者的救治中广泛应用氢化可的松。但2018年3月,发表在《N Engl J Med》的一项研究显示,在进行机械通气的感染性休克患者中,持续输注氢化可的松未能降低90天死亡率。

背景:氢化可的松是否会降低感染性休克患者的死亡率尚不明确。

方法:研究者将进行机械通气的感染性休克患者分配至使用氢化可的松(每天200 mg的剂量)或安慰剂,为期7天,直至死亡或从重症监护室(ICU)出院,哪个先出现均可。主要结局为90天全因死亡率。

结果:从2013年3月至2017年4月,共计3800例患者参与随机分配。在3658例患者中确定主要结局相关状态(分配至氢化可的松组1832例,分配至安慰剂组1826例)。90天时,氢化可的松组511例(27.9%)患者死亡,安慰剂组为526例(28.8%)(比值比,0.95;95%置信区间[CI],0.82~1.10;P=0.50)。6个预先设定亚组的试验方案相似。分配至氢化可的松组的患者休克解时间比安慰剂组更短(中位时长,3天 [四分位间距,2~5] vs 4天[四分位间距,2~9];风险比,1.32;95% CI,1.23~1.41;P<0.001)。氢化可的松组起始机械通气的时间比安慰剂组更短(中位,6天[四分位间距,3~18] vs 7天[四分位间距,3~24];比值比,1.13;95% CI,1.05~1.22;P<0.001)。但考虑再次机械通气时,两组存活和无机械通气天数无差别。氢化可的松组患者接受输血的人数比安慰剂组更少(37.0% vs 41.7%;比值比,0.82;95% CI,0.72~0.94;P=0.004)。两组的28天死亡率、休克复发率、ICU出院存活天数、出院存活天数、机械复发率、肾脏替代治疗率、新发菌血症或败血症的发病率没有差异。

结论:在进行机械通气的感染性休克患者中,持续输注氢化可的松的90天死亡率不低于安慰剂组(基金支持:National Health and Medical Research Council of Australia and others;ADRENAL ClinicalTrials.gov number,NCT01448109)。
