Adjuvant treatments to invasive mechanical ventilation in the management of acute respiratory distress syndrome secondary to COVID-19

INTRODUCTION: This bibliographic review is carried out in order to obtain answers about aspects related to techniques and treatments, as well as care associated with the critically ill patient diagnosed with Covid-19. OBJECTIVE: To analyze the available scientific evidence on the effectiveness of the use of invasive mechanical ventilation together with other adjuvant techniques, in reducing the mortality rate in patients with Acute Respiratory Distress Syndrome and clinical trial of Covid-19 treated in intensive care units. METHODOLOGY: A systematized bibliographic review was carried out in the Pubmed, Cuiden, Lilacs, Medline, Cinahl and Google Scholar databases, using MeSH terms (Adult Respiratory Distress Syndrome, Mechanical Ventilation, Prone Position, Nitric Oxide, Extracorporeal Membrane Oxygenation, Nursing Care) and the corresponding Boolean operators. The selected studies underwent a critical reading carried out between December 6, 2020 and March 27, 2021 using the Critical Appraisal Skills Program tool in Spanish and a cross-sectional epidemiological studies evaluation instrument. RESULTS: A total of 85 articles were selected. After performing the critical reading, a total of 7 articles were included in the review, 6 being descriptive studies and 1 cohort study. After analyzing these studies, it appears that the technique that has obtained the best results is ECMO, with the care provided by qualified and trained nursing staff being very important. CONCLUSION: Mortality from Covid-19 increases in patients treated with invasive mechanical ventilation compared to patients treated with extracorporeal membrane oxygenation. Nursing care and specialization can have an impact on improving patient outcomes.
