Crit Care:非急性呼吸窘迫综合征患者较高和较低呼气末正压对比分析

2021-07-15 MedSci原创 MedSci原创

在这项RCT荟萃分析中,与较低PEEP相比,较高PEEP与接受有创机械通气的非ARDS患者死亡率无关。需要进一步的大型高质量RCT来证实这些结果。

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,研究人员对评估了接受因急性呼吸窘迫综合征 (ARDS) 以外的原因进行有创机械通气的重症监护病房 (ICU) 患者较高呼气末正压(PEEP)与住院死亡率之间关联的随机对照试验 (RCT) 进行了系统回顾和荟萃分析,并与较低呼气末正压(PEEP)进行比较。

研究人员对MEDLINE、EMBASE、Scopus、Cochrane Central Register of Controlled Trials、CINAHL和Web of Science电子数据库进行了检索,没有语言限制,检索时间从数据库成立到2021年6月16日。此外,研究人员还检索了在研数据库和灰色文献。

研究人员确定了22项比较了较高PEEP(1007名患者)和较低PEEP(991名患者)的RCT(2225名患者)。未观察到较高PEEP与住院死亡率之间存在的统计学显著的关联(风险比为1.02,95%置信区间为0.89-1.16;I2=0%,p=0.62;证据质量低)。

主要结局和主要次局森林图

在次要结局中,较高的PEEP与更好的氧合、较高的呼吸系统顺应性以及较低的低氧血症和ARDS发生风险相关。此外,两组之间的气压伤、低血压、通气时间、住院时间和ICU死亡率相似。

由此可见,在这项RCT荟萃分析中,与较低PEEP相比,较高PEEP与接受有创机械通气的非ARDS患者死亡率无关。需要进一步的大型高质量RCT来证实这些结果。

正压通气是临床上重要的治疗手段,但却导致了呼吸机相关性肺损伤的临床症状出现。肺保护性机械通气策略各有不同,但都旨在减少或防止呼吸机相关性肺损伤。然而,少有策略被证明有效。为了更好地了解导致呼吸机相关性肺损伤的生物学机制,需要隔离出机械通气模型来探讨它在急性肺损伤发展中的作用。
