Intra-operative extracorporeal membrane oxygenation use in pediatric lung transplantation--the Zurich experience.

There is a lack of data regarding use of ECMO in children undergoing lung transplantation. We evaluated our experience of ECMO in pediatric lung transplant recipients. All patients (<18 yr) who underwent lung transplants between 1997 and 2011 were included (17 children; nine males; median age 16 yr), and the use of intra-operative ECMO evaluated. Transplant procedures were carried out with intra-operative ECMO in seven children (all bilateral lung transplants). Demographics of ECMO and non-ECMO patients were comparable. One child was already on ECMO pre-operative. Lung graft size reduction was undertaken in five ECMO and four non-ECMO cases, respectively. Five patients were taken off ECMO intra-operatively; the other patients were weaned off ECMO within 48 h post-operatively. Three-months survival was 100%. By 12 months post-transplantation, one patient each died in the ECMO and in the non-ECMO group. At the end of the study, six of seven ECMO cases were still alive (median survival 48.5 months); one patient required a retransplant at 53 months. Our small case series suggests that lung transplant procedures can be safely carried out in selected children on intra-operative ECMO support; however, our pediatric experience regarding this scenario is very limited but probably almost unique.

Practical approach to emergencies in lung transplant recipients: how we do it.

Lung transplant recipients (LTRs) are prone to medical complications and emergencies due to the transplanted organ being in constant direct contact with the environment and the need for life-long profound immunosuppression (IS). As a result of these specific circumstances, the medical and surgical management of LTRs frequently differs from usual standard care. Therefore, we outline here some of the principles we take into account when dealing with the most frequent medical emergencies encountered in our lung transplant cohort in Zurich. The main topics dealt with are: diagnostics and treatment of infections, gastrointestinal emergencies, IS and other medication issues as well as work-up of unclear inflammatory signs and peri-operative precautions in LTRs. Early post-operative transplant complications, rare medical emergencies and surgical problems are not covered. Our report is intended to help internists and pulmonologists new to the field to obtain a better understanding of the peculiarities of LTRs and their management.
