JAMA:老药乙酰唑胺要不要用于COPD接受机械通气患者?(DIABOLO研究)

2016-02-03 MedSci MedSci原创

作为呼吸兴奋剂用于慢性阻塞性肺疾病(COPD)和代谢性碱中毒患者的治疗,acetazolamide已应用数十年,但是并没有大型随机安慰剂对照试验来证实这种方法的可用性。本研究旨在确定acetazolamide是否可减少COPD及代谢性碱中毒患者的机械通气时间。

MedSci小编提示:

这么经典的老药,也能发表在JAMA上!主要在于随着时间推移,过去很多认识都应该随之而改变,新药需要临床不断观察和评价,老药同样如此。

作为呼吸兴奋剂用于慢性阻塞性肺疾病(COPD)和代谢性碱中毒患者的治疗,乙酰唑胺(acetazolamide)已应用数十年,但是并没有大型随机安慰剂对照试验来证实这种方法的可用性。本研究旨在确定acetazolamide是否可减少COPD及代谢性碱中毒患者的机械通气时间。

DIABOLO研究为一项随机双盲安慰剂对照的多中心试验,试验时间自2011年10月至2014年7月, 涉及15个法国ICUs,共纳入了382名需要接受超过24小时机械通气治疗的COPD患者。随机分为安慰剂组和acetazolamide治疗组,其中380名患者纳入意向分析治疗中。对于代谢性碱中毒患者在其进入ICU48小时之内静脉注射acetazolamide(500-1000 mg,每天两次)或安慰剂治疗,且患者在ICU治疗期间一直输注,最长时间为28天。主要结局为经气管插管或气管切开行机械通气治疗的时间。次要结局包括患者动脉血气和呼吸参数的变化,脱离呼吸机的时间,不良反应事件,拔管后无创通气的使用,成功撤机,ICU入住时间以及ICU内死亡率。

最终380名(平均年龄为69岁,272名男性,379例气管插管病例)患者完成了研究。187名患者接受acetazolamide治疗,193名接受安慰剂治疗。结果发现,两组患者在机械通气治疗持续时间中位数,脱离机械通气时间,每分钟通气量的每日变化以及局部动脉血中二氧化碳分压上并无显著差异。但是,acetazolamide治疗组患者血清碳酸氢盐的每日变化更大,代谢性碱中毒的天数也显著降低。其他的次要解决并无明显组间差异。

COPD患者接受有创性机械通气治疗时,联合使用acetazolamide并不会显著减少患者接受机械通气支持的时间。但是,联合使用acetazolamide治疗所带来的结果具有很最重要的临床意义,而且,可能是本研究在建立统计学意义上存在不足。
