Prone positioning before extracorporeal membrane oxygenation for severe acute respiratory distress syndrome: A retrospective multicenter study

초록

Objective: To evaluate the clinical outcomes of patients with severe acute respiratory distress syndrome (ARDS) subjected to prone positioning before extracorporeal membrane oxygenation (ECMO). Design: A retrospective analysis of a multicenter cohort was carried out. Setting: Patients admitted to the Intensive Care Units of 11 hospitals in Korea. Patients: Patients were divided into those who underwent prone positioning before ECMO (n = 28) and those who did not (n = 34). Interventions: None. Variables of interest: Thirty-day mortality, ECMO weaning failure rate, mechanical ventilation weaning success rate, mechanical ventilation-free days at day 60. Results: The prone group had lower median peak inspiratory pressure and lower median dynamic driving pressure before ECMO. Thirty-day mortality was 21% in the prone group and 41% in the non-prone group (p = 0.098). The prone group also showed a lower ECMO weaning failure rate, and a higher mechanical ventilation weaning success rate and more mechanical ventilation-free days at day 60. In the non-prone group, median dynamic compliance marginally decreased shortly after ECMO, but no significant change was observed in the prone group. Conclusions: Prone positioning before ECMO was not associated to increased mortality and tended to exert a protective effect. (C) 2018 Elsevier Espana, S.L.U. y SEMICYUC. All rights reserved.
