Prone position in spontaneous ventilation? An induction problem: A scoping review

ABSTRACT

Intoduction Prone position in spontaneous ventilation is not a recent strategy, and despite the many years it has been trying to consolidate, it has not been able to prove to be of real utility. During the recent pandemic, prone spontaneous ventilation re-emerged as a practical and simple alternative, although it was highly questioned due to its weak level of evidence. With time and experience, it was gradually relegated to become only an attractive hypothesis. Objective: This study aims to analyze the potential benefits of prone position in spontaneous ventilation in patients with hypoxemia caused by SARS-CoV-2. Methods: A panoramic review of the most relevant studies published in the MEDLINE, Embase and Scopus databases up to December 20, 2021 was performed. Results: After screening, 4 observational studies, 1 randomized clinical trial, and 3 systematic reviews were selected for analysis. Conclusions: By statistical analysis we concluded that prone position in spontaneous ventilation, although it could delay intubation, did not improve survival in hypoxemic subjects with viral pneumonia caused by coronavirus type 2. © 2023 Asociación Colombiana de Medicina Crítica y Cuidado lntensivo
