摘要 目的 分析急诊重症监护室ARDS患者新发血小板减少的原因,探讨新发血小板减少对ARDS预后的影响.方法 对2009-11~2011-03期间入住急诊重症监护室(EICU)的629例患者进行前瞻性研究,根据患者入EICU 5 d内血小板水平分为三组,组1:新发血小板减少不伴ARDS;组2:ARDS伴新发血小板减少;组3:ARDS不伴血小板减少.分析三组患者血生化指标,使用CRRT、机械通气治疗情况,EICU住院时间及死亡率.结果 ARDS合并新发血小板减少患者(组2)较非ARDS患者(组1)显著增多(46%和4.5%,P〈0.001);组2、组3 EICU死亡率比较差异无统计学意义(P=0.14);但组2存活患者EICU住院时间较组3明显延长(30 d和17 d,P=0.017);新发血小板减少者30 d内未恢复正常者较恢复正常者EICU死亡率显著增高(71.4%和21.4%,P=0.015).结论 ARDS患者易并发血小板减少,新发血小板减少可致ARDS患者EICU住院时间延长;30 d内血小板减少未能恢复正常者EICU死亡率显著升高;新发血小板减少可能与炎症反应及行CRRT、机械通气治疗有关.
