Duration of the first prone positioning maneuver and its association with 90-day mortality in patients with acute respiratory failure due to COVID-19: A retrospective study of time terciles.

Objective: To investigate the association between the duration of the first prone positioning maneuver (PPM) and 90-day mortality in patients with C-ARDS.

Design: Retrospective, observational, and analytical study.

Setting: COVID-19 ICU of a tertiary hospital.

Association between different corticosteroid regimens used in severe SARS-CoV-2 infection and short-term mortality: retrospective cohort study.

Introduction: During the SARS-CoV-2 pandemic, several corticosteroid regimens have been used in the treatment of the disease, with disparate results according to drug and regimen used. For this reason, we wanted to analyze differences in early mortality derived from the use of different regimens of dexamethasone and methylprednisolone in SARS-CoV-2 infection in critically ill patients requiring admission to an ICU.

Method: Observational, analytical and retrospective study, in an intensive care unit of a third-level university hospital, (March 2020 and June 2021).
