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
ABSTRACT
INTRODUCTION: high-oxygen nasal cannulas in patients with respiratory failure secondary to SARS-CoV-2 pneumonia have not been studied from a cost-effectiveness point of view. METHODS: Retrospective analysis of patients who had entered the COVID-area of an intensive medicine service in a third reference hospital, between March-December 2020. An effectiveness cost analysis was carried out comparing 2therapeutic decisions: the experimental strategy was defined as a mixed strategy consisting of the initial application of high flow nasal oxygen (HFNO) and application of VMI only to HFNO failures. The optimal rational decision was defined as maximizing expected profit, and economic efficiency was assessed by calculating the Incremental Cost-Effectiveness Ratio (ICER) for years of life gained. RESULTS: Of the 185 patients tested, 101 (55%) received invasive mechanical ventilation immediately and 84 (45%) were treated with HFNO at the outset. In the cost-effectiveness analysis, comparing both therapeutic strategies, the probability that the experimental strategy would be more effective was 0.974, reaching statistical significance: Difference in average proportions -0.113; 95% CI:-0.018 to -0.208. This corresponds to an NNT of 9 patients. The optimal decision was HFNO's strategy followed by VMI in HFNO failures. This option had an RCEI of 5582 euros per year of life gained. CONCLUSIONS: It is important to establish in the future reliable markers in the use of HFNO so that this therapy improves its cost-effective benefits.
ABSTRACT
Resumen El 31 de diciembre de 2019, la Comisión de Salud de la provincia China de Hubei, dio a conocer por primera vez un grupo de casos inexplicables de neumonía, que posteriormente la OMS definió como el nuevo coronavirus de 2019 (SARS-CoV-2). El SARS-CoV-2 ha presentado una transmisión rápida de persona a persona y actualmente es una pandemia mundial. En la mayor serie de casos descrita hasta la fecha de pacientes hospitalizados con enfermedad por SARS-CoV-2 (2019-nCoViD), el 26% requirió atención en una unidad de cuidados intensivos (UCI). Esta pandemia está provocando una movilización de la comunidad científica sin precedentes, lo que lleva asociado un numero exponencialmente creciente de publicaciones en relación con la misma. La presente revisión bibliográfica narrativa, tiene como objetivo reunir las principales aportaciones en el área de los cuidados intensivos hasta la fecha en relación con la epidemiología, la clínica, el diagnóstico y el manejo de 2019-nCoViD.
