Prone position in COVID 19-associated acute respiratory failure

Aileen Kharat et al. Curr Opin Crit Care. .

Abstract

Purpose of review: Prone position has been widely used in the COVID-19 pandemic, with an extension of its use in patients with spontaneous breathing ('awake prone'). We herein propose a review of the current literature on prone position in mechanical ventilation and while spontaneous breathing in patients with COVID-19 pneumonia or COVID-19 ARDS.

Recent findings: A literature search retrieved 70 studies separating whether patient was intubated (24 studies) or nonintubated (46 studies). The outcomes analyzed were intubation rate, mortality and respiratory response to prone. In nonintubated patient receiving prone position, the main finding was mortality reduction in ICU and outside ICU setting.

Summary: The final results of the several randomized control trials completed or ongoing are needed to confirm the trend of these results. In intubated patients, observational studies showed that responders to prone in terms of oxygenation had a better survival than nonresponders.

Contoured-Funnel plots displaying the relationship between the effect of size on the x-axis and the standard error on the y-axis for intubation and mortality at the latest recording time. Grey, dark grey, and light grey contours pertain to less than 0.1, less than 0.05, and less than 0.01 levels of significance, respectively. The favorable effect of the experimental group, that is, the prone position, is shown in the left hand side of the funnel plots.
