Abstract

VARGAS GARCIA, Irvin Jair et al. Prono position: a non-ventilatory strategy in patients with severe pneumonia due to SARS-CoV-2. Med. crít. (Col. Mex. Med. Crít.) [online]. 2022, vol.36, n.4, pp.197-201.  Epub Dec 02, 2022. ISSN 2448-8909.  https://doi.org/10.35366/105789.

Introduction:

Severe pneumonia due to SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) causes severe hypoxemia, therefore, the guidelines for the management of critically ill adult patients with COVID-19 recommend the use of the prone position to improve oxygenation.

Material and methods:

A prospective, descriptive and analytical cohort study. Patients admitted to the intensive care unit in the period from April 18, 2020 to August 18, 2021 with confirmed IMV secondary to severe SARS-CoV-2 pneumonia.

Results:

In the period covered, 110 patients who met the inclusion criteria were included. Of the total, 88 patients were included in the group with sustained improvement at prone withdrawal and 22 in the group with non-sustained improvement at prone withdrawal. It was observed that the% Decrease in PaO2/FiO2 upon prone removal is useful to predict mortality with AUC of 0.740 with 95% CI of (0.646-0.834) and p = 0.001.

Conclusion:

A > 50% decrease in PaO2/FiO2 upon removal from prolonged prone position or unsustained improvement is a predictor of mortality in patients with severe SARS-CoV-2 pneumonia.

Keywords : Prone position; nonsustained improvement; mortality.
