Pre-transplant mechanical ventilation and outcome in patients with cystic fibrosis.

ABSTRACT

Mechanical ventilation for ventilatory failure has been considered a relative contraindication to subsequent lung transplantation. The purpose of this study was to test the hypothesis that patients with cystic fibrosis (CF) who are intubated and mechanically ventilated before transplantation have poorer post-transplant outcomes than do patients who are not ventilated. We compared the outcomes of 8 patients with CF who underwent mechanical ventilation for 62 +/-20 days (range, 3-153 days) before bilateral lung transplantation with outcomes of 24 patients with CF who did not undergo pre-transplant mechanical ventilation. Although time to extubation after transplantation was prolonged significantly (11 vs 4 days) for the pre-transplant ventilated group, days to hospital discharge, forced expiratory volume in 1 second (percent predicted) at 1 year after transplantation, and post-transplant survival as determined using the Kaplan-Meier method did not differ statistically between the 2 groups. Patients with CF who undergo pre-transplant endotracheal intubation and mechanical ventilation for respiratory failure have outcomes that do not differ significantly from those of patients with CF who do not require invasive ventilatory support before bilateral lung transplantation.
