Factors Associated with Survival in Patients Undergoing Invasive Mechanical Ventilation in an Intensive Care Unit in Colombia, 2017–2018: A Retrospective Cohort Study
To evaluate the efficacy of earlier and late tocilizumab (TCZ) infusion, that is, prior to and after initiation of mechanical ventilation, in reducing mortality in a cohort of patients with severe COVID-19 pneumonia who required support in the intensive care unit (ICU).
We conducted a retrospective cohort study to assess respiratory colonization before and after the use of chlorhexidine oral decontamination among a cohort of intensive care unit patients who received mechanical ventilation. We observed a decrease in the prevalence of Enterobacteriaceae and an increase in the incidence of fungal colonization. Chlorhexidine oral decontamination might have a differential effect on respiratory colonization.
