¿Prono en ventilación espontánea? Un problema de inducción: una revisión panorámica

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.
