JAMA:急性呼衰,无创通气真的有效?

2015-10-15 sapphira 译 MedSci原创

重要性:无创通气被推荐用于降低急性低氧性呼吸衰竭病人的死亡率,但其有效率尚不清楚。 目的:探究早期使用无创通气是否可以提高免疫力低下的不高碳酸血症急性低氧性呼吸衰竭病人的生存率。 研究设计、研究对象:我们于2013年8月12日至2015年1月2日之间,在法国和比利时的28个ICU的374个十分严重的病人中进行了多中心随机试验,其中317人(84.7%)在接受血液恶性肿瘤或者实体肿瘤的治

重要性:无创通气被推荐用于降低急性低氧性呼吸衰竭病人的死亡率,但其有效率尚不清楚。

目的:探究早期无创通气是否可以提高免疫力低下的急性低氧性呼吸衰竭病人的生存率。

研究设计、研究对象:研究人员于2013年8月12日至2015年1月2日之间,在法国和比利时的28个ICU的374个十分严重的病人中进行了这个多中心随机试验,其中317人(84.7%)在接受血液恶性肿瘤或者实体肿瘤的治疗。

干预方法:患者被随机分为无创通气组(191人)和单纯氧疗组(183人)。

主要观察指标和方法:主要观察第28天的死亡率,次要观察气管插管率、序贯脏器衰竭评分、ICU获得性感染、机械通气时长和ICU住院时间。

结果:在随机的情况下,无创通气组中位氧流量是9L/min(四分位点内距5-15),氧疗组也是9L/min(四分位点内距5-15)。无创通气组的所有病人在入组后立刻开始无创通气,第二天有46例死亡(24.1%),氧疗组有50例死亡(27.3%)(绝对差−3.2 [95% CI, −12.1 to 5.6]; P=.47)。共有155例病人(41.4%)发生氧合衰竭,73例(38.2%)在无创通气组,82例(44.8%)在氧疗组(绝对差−6.6 [95% CI, −16.6 to 3.4]; P=.20)。ICU获得性感染、住院时长和机械通气时长两组无明显差异。

结论:对于收入ICU的免疫力低下的急性低氧性呼吸衰竭病人,早期无创通气和单纯氧疗相比未能降低28天死亡率。但因研究有局限性,还需要更多更深入的研究以确定最终结论。
