Idiopathic pulmonary fibrosis patient supported with extracorporeal membrane oxygenation for 403 days while waiting for a lung transplant: A case report.

ABSTRACT: According to the Extracorporeal Life Support Organization, the average duration of veno-venous extracorporeal membrane oxygenation (V-V ECMO) in adults with acute respiratory failure is 10.5-13.5 days. Some patients on V-V ECMO may not recover in such a short period of time, and recently, there have been more reports of prolonged V-V ECMO. However, we do not know how long it is feasible to wait for native lung recovery or lung transplant (LTx) with the use of ECMO. We describe a patient with acute exacerbation of idiopathic pulmonary fibrosis supported by ECMO for 403 days while waiting for a LTx. In this case, we kept the patient awake, and he was communicating frequently with his family. We changed the membrane oxygenator 23 times and the cannula 10 times without complication. However, we terminated the treatment on day 403 of ECMO because there was no access site for cannula insertion due to blockage by a venous thrombotic occlusion, making it impossible to continue this bridge to lung transplantation. It has become possible to maintain patients on ECMO for extended periods of time, but it is difficult to manage ECMO for more than one year without the development of a more durable lung support system.

Project description:ObjectivesTo evaluate the association between bleeding from chest tubes and clinical outcomes in children supported by extracorporeal membrane oxygenation.DesignSecondary analysis of a large observational cohort study.SettingEight pediatric institutions within the Eunice Kennedy Shriver National Institute of Child Health and Human Development's Collaborative Pediatric Critical Care Research Network.PatientsCritically ill children supported by extracorporeal membrane oxygenation.InterventionsNone.Measurements and main resultsDaily chest tube bleeding, results from hemostatic assays, transfusion volumes, 90-day PICU-free days, and mortality were collected prospectively by trained bedside extracorporeal membrane oxygenation specialists and research coordinators. Extracorporeal membrane oxygenation was employed in the care of 514 consecutive patients. Sixty percent of patients had at least one episode of chest tube bleeding (median chest tube blood volume over the entire extracorporeal membrane oxygenation course was 123 mL/kg [interquartile range, 47-319 mL/kg]). Twenty-six percent had at least 1 day of bleeding from the chest tube greater than 100 mL/kg/d. The number of days with chest tube bleeding greater than 60 mL/kg/d was independently associated with increased in-hospital mortality (adjusted odds ratio, 1.43; 95% CI, 1.05-1.97; p = 0.02) and decreased PICU-free days (beta coefficient, -4.2; 95% CI, -7.7 to -0.6; p = 0.02). The total amount of bleeding from chest tube were independently associated with increased mortality (per mL/kg/extracorporeal membrane oxygenation run; adjusted odds ratio, 1.002; 95% CI, 1.000-1.003; p = 0.04). Fibrinogen, weight, indication for extracorporeal membrane oxygenation, and need for hemodialysis were independently associated with chest tube bleeding, whereas platelet count, coagulation tests, heparin dose, and thrombotic events were not.ConclusionsIn children supported by extracorporeal membrane oxygenation, chest tube bleeding above 60 mL/kg/d was independently associated with worse clinical outcome. Low fibrinogen was independently associated with chest tube bleeding, whereas platelet count and hemostatic tests were not. Further research is needed to evaluate if interventions to prevent or stop chest tube bleeding influence the clinical outcome.

Project description:BackgroundIt is unclear whether continuing anti-fibrotic therapy until the time of lung transplant increases the risk of complications in patients with idiopathic pulmonary fibrosis.ObjectivesTo investigate whether the time between discontinuation of anti-fibrotic therapy and lung transplant in patients with idiopathic pulmonary fibrosis affects the risk of complications.MethodsWe assessed intra-operative and post-transplant complications among patients with idiopathic pulmonary fibrosis who underwent lung transplant and had been treated with nintedanib or pirfenidone continuously for ⩾ 90 days at listing. Patients were grouped according to whether they had a shorter (⩽ 5 medication half-lives) or longer (> 5 medication half-lives) time between discontinuation of anti-fibrotic medication and transplant. Five half-lives corresponded to 2 days for nintedanib and 1 day for pirfenidone.ResultsAmong patients taking nintedanib (n = 107) or pirfenidone (n = 190), 211 (71.0%) had discontinued anti-fibrotic therapy ⩽ 5 medication half-lives before transplant. Anastomotic and sternal dehiscence occurred only in this group (anastomotic: 11 patients [5.2%], p = 0.031 vs patients with longer time between discontinuation of anti-fibrotic medication and transplant; sternal: 12 patients [5.7%], p = 0.024). No differences were observed in surgical wound dehiscence, length of hospital stay, or survival to discharge between groups with a shorter versus longer time between discontinuation of anti-fibrotic therapy and transplant.ConclusionAnastomotic and sternal dehiscence only occurred in patients with idiopathic pulmonary fibrosis who discontinued anti-fibrotic therapy < 5 medication half-lives before transplant. The frequency of other intra-operative and post-transplant complications did not appear to differ depending on when anti-fibrotic therapy was discontinued.Registrationclinicaltrials.gov NCT04316780: https://clinicaltrials.gov/ct2/show/NCT04316780.
