Background: In 2011 we reported unfavourable outcomes of second-run extracorporeal life support (ECLS) in children. We wanted to investigate whether this previous report affected our strategy and modified our long-term outcomes.Methods: Between 1988 and 2015, 31 patients underwent a second-run ECLS. Median age at the time of first support was 9days (0-16 years). Median length of support for the first and second runs were 4.7days (0.1-10) and 3.6days (0.5-8.7) respectively, with an interval of 1.8days (0.1-66) between supports.Results: There was an increasing trend in the number of patients undergoing second-run ECLS after our report: 21 patients between 1988 and mid-2010 (0.9 patients/year) and 10 between mid-2010 and 2015 (two patients/year) (p=0.06). However, among all the patients who underwent ECLS, the proportion of second-run ECLS was not different before and after 2010 (4% vs. 4.2% respectively, p=0.92). While 58% of patients (18/31) survived weaning of support, only 23% (7/31) survived to hospital discharge and 14% (5/31) were still alive after hospital discharge at a median of 6.5 years (1.2-11.6). The three patients who had positive long-term outcomes had the second-run ECLS instituted to allow for major cardiac operations.Conclusions: Compassionate use of second-run ECLS is difficult to refuse but one should be aware that its outcomes are dismal. In our centre, benefits seem to be limited to cases where the second-run ECLS allows for a major cardiac intervention. [ABSTRACT FROM AUTHOR]

We describe our experience of 30 consecutive children supported with ECMO and receiving 20 ppm of nitric oxide in the oxygenator of the ECMO circuit. Administration of nitric oxide into the ECMO circuit is safe and could potentially mitigate ischaemia reperfusion injury and end-organ dysfunction of children requiring mechanical support.
