A Multicenter Study María Lucía Giménez Gabriel Alejandro Verde Iris Gloria Salvati Walter Ariel Tozzi Adriano Javier Cura Silvina Borello Paola Bustamante Sacha Alexis Virgilio Marco Bezzi Medicina weaning mortality Epidemiology invasive mechanical ventilation The weaning process includes the release from the ventilatory support and endotracheal tube. It is classified into simple, difficult and prolonged, according to its difficulty and duration. The purpose was to describe the epidemiological characteristics of patients successfully weaned from invasive mechanical ventilation and establish associations between the different types of weaning and the variables influencing the evolution of these characteristics associated with mortality. We conducted a multicenter, prospective, longitudinal, analytical cohort study in three intensive care units of the Autonomous City of Buenos Aires, Argentina. We included patients who required invasive mechanical ventilation for more than 12 hours and were successfully weaned from it. The variables to be analyzed were: type of weaning, amount of days the patients received invasive mechanical ventilation, extubation failure and length of stay and mortality in the intensive care unit. The prevalence of simple, difficult or prolonged weaning was 52.2% (95/182), 25.8% (47/182) and 22% (40/182), respectively. The average of days the patients received invasive mechanical ventilation increased to 3.5 every time the category changed (B Coefficient: 3.5; SE [standard error] = 0.6). Patients with extubation failure presented a higher risk of prolonged weaning (OR [odds ratio] = 23; CI [confidence interval] = 95%: 3.55-149.45). No association was found between mortality and type of weaning (OR = 0.68; 95% CI: 0.31-1.51). In conclusion, the type of weaning was not associated with mortality in the intensive care unit. The extubation failure, tracheostomy and presence of delirium were associated with a larger amount of days receiving invasive mechanical ventilation. 2016 artículo científico 1852-1630 https://www.redalyc.org/articulo.oa?id=382145839003 en http://www.redalyc.org/revista.oa?id=3821 Revista Americana de Medicina Respiratoria application/pdf Asociación Argentina de Medicina Respiratoria Revista Americana de Medicina Respiratoria (Argentina) Num.2 Vol.16 |
