Crit Care Med:机械通气患者的临床结局:早期深度镇静vs 轻度镇静

2018-03-13 吴星 环球医学

2018年3月,发表在《Crit Care Med》的一项系统评价和Meta分析,对机械通气患者,早期接受不同深度镇静对死亡结局的影响进行了考察。

2018年3月,发表在《Crit Care Med》的一项系统评价和Meta分析,对机械通气患者,早期接受不同深度镇静对死亡结局的影响进行了考察。

目的:越来越多的研究数据显示早期深度镇静或会对临床结局产生不利的影响。该项系统评价和Meta分析与世界文献中所描述的一样:明确并量化机械通气开始后48个小时内深度镇静的影响。主要结局为死亡率。次要结局包括住院时长、入住ICU的时长、机械通气时长,以及谵妄和气管切开的频率。

数据出处:对如下的数据资源进行了检索:MEDLINE、EMBASE、Scopus、Cochrane Central Register of Controlled Trials、Database of Abstracts of Reviews and Effects、Cochrane Database of Systematic Reviews databases、ClinicalTrials.gov、会议记录,以及参考文献列表。

研究筛选:纳入随机对照试验和非随机研究。

数据提取:两名研究者对选定的符合纳入标准的研究摘要进行独立筛选。

数据综合:纳入了2012年~2017年间发表的9项研究(4521例患者)。一个随机效应Meta分析模型显示,与深度镇静(27.6%)相比,早期轻度镇静(9.2%)与较低的死亡率相关(比值比RR,0.34 [0.21~0.54])。轻度镇静与较短的机械通气(平均差异,–2.1;95% CI,–3.6~–0.5)和ICU入住天数(平均差异,–3.0 ,95% CI,–5.4~–0.6)相关。轻度镇静组的谵妄频率为28.7%,深度镇静组的谵妄频率为48.5%,比值比为0.50(0.22~1.16)。

结论:正如少数符合条件的存在异质性的随机对照试验和观察性研究的评价显示,机械通气患者接受深度镇静与死亡率和住院时长增加相关。针对急诊部开始和随后入住ICU时早期镇静深度评估的干预值得进一步研究,并可改善结局。

机械通气是抢救危重症病人的一大利器,但其复杂繁多的参数应如何设置?

机械通气是指利用机械装置,通过建立气道口与肺泡间的压力差,改善或维持通气和换气功能,纠正低氧血症和高碳酸血症的一种呼吸支持技术,主要目的是为原发病的治疗争取时间。

Crit care med:机械通气患者早期镇静是否有益?

越来越多的数据表明,早期的深度镇静可能会对临床结果产生一定的负面影响。近期,一项发表在杂志Crit care med上的系统综述和荟萃分析定义和量化了机械通气开始的48小时内深度镇静产生的影响。主要结果是死亡率,次要终点包括住院和ICU的住院时间,机械通气时间,谵妄和气管切开发生的频率。此项检索的数据来源有MEDLINE、EMBASE、Scopus、Cochrane对照试验中心登记册,综述和效果的
