Crit Care:肺炎诱导的早期轻度急性呼吸窘迫综合征患者无创通气的疗效

2019-09-21 xing.T MedSci原创

由此可见,尽管NIV治疗可观察到PaO2/FIO2有所改善,但与标准氧气疗法相比,NIV治疗并不能减少肺炎诱发的早期轻度ARDS患者进行气管插管的需求。较高的每分钟通气量可能预示着NIV治疗失败。

研究人员的预试验表明,对于早期轻度急性呼吸窘迫综合征(ARDS,PaO2/FIO2在200到300之间)患者,与传统的吸氧方式相比,无创通气(NIV)降低了插管的需求。近日,危重病医学领域权威杂志Critical Care上发表了一篇研究文章,研究人员旨在评估NIV是否可以减少肺炎诱发的早期轻度急性呼吸窘迫综合征患者的有创通气的需求。

研究人员进行了一项前瞻性、多中心、随机对照试验(RCT)将文丘里面罩常规给药与NIV进行了比较。该研究的主要结局包括符合气管插管标准的患者人数。

研究人员将来自21个中心的200名受试者随机分为NIV组(n=102)或对照组(n=98)。两组患者的基线特征相似。在NIV组中,PaO2/FIO2在随机分组后2 h明显高于对照组,并在最初的72 h保持稳定。与对照组相比,NIV并未降低需要气管插管的患者比例(11/102 vs. 9/98,10.8% vs. 9.2%,p=0.706)。两组患者ICU死亡率相似(7/102 vs. 7/98,4.9% vs. 3.1%,p=0.721)。多变量分析显示,在48 h时,每分钟通气量大于11/L/min是NIV失败的独立危险因素(OR为1.176 [95%CI为1.005–1.379],p=0.043)。

由此可见,尽管NIV治疗可观察到PaO2/FIO2有所改善,但与标准氧气疗法相比,NIV治疗并不能减少肺炎诱发的早期轻度ARDS患者进行气管插管的需求。较高的每分钟通气量可能预示着NIV治疗失败。
