RESUMO
BACKGROUND: Despite therapeutic advances, people with cystic fibrosis (CF) develop progressive worsening and exacerbations of their lung disease, which can lead to acute respiratory failure. Historically, survival after mechanical ventilation (MV) has been poor. Outcomes related to use of extracorporeal membrane oxygenation (ECMO) have not been well described in CF. METHODS: We conducted a retrospective analysis of adult patients with CF admitted to the ICU for acute respiratory failure and requiring invasive MV with or without ECMO between July 1, 2006 and June 30, 2016. Separate analysis for the subgroup of MV patients who were eligible for transplant was conducted. RESULTS: Mortality for all patients with respiratory failure requiring advanced support was 37%. Ten of 28 (36%) MV patients, 10 of 26 (38%) ECMO+MV patients and 7 of the 21 (33%) transplant eligible MV patients died. Intensive care unit (ICU) length of stay (LOS) was 24.5±16.6 days for ECMO+MV; 12.9±9.0 days for MV (p=0.001), and 12.3 ±10 days for transplant eligible MV patients (p=0.005 for ECMO+MV comparison). Seven transplant eligible MV patients (33%) and 16 ECMO+MV patients (62%) underwent lung transplantation (p<0.001) during the hospital admission. One and 2-year survival for individuals who survived ICU admission was similar regardless of mode of support. Cox-proportional hazards model did not yield any variables that significantly influenced ICU mortality, 1-year or 2-year mortality. CONCLUSION: Survival for CF patients with acute respiratory failure requiring MV with or without ECMO has improved over time. ECMO may be an appropriate modality for respiratory support in patients with CF and acute respiratory failure who have greater risk of death from MV alone.
