The purpose of this report is to describe the international growth, outcomes, complications and technology used in pediatric extracorporeal life support (ECLS) from 2009 to 2015 as reported by participating centers in the Extracorporeal Life Support Organization (ELSO). To date, there are 59,969 children who have received ECLS in the ELSO Registry; among those, 21,907 received ECLS since 2009 with an overall survival to hospital discharge rate of 61%. In 2009, 2,409 ECLS cases were performed at 157 centers. By 2015, that number grew to 2,992 cases in 227 centers, reflecting a 24% increase in patients and 55% growth in centers. ECLS delivered to neonates (0–28 days) for respiratory support was the largest subcategory of ECLS among children <18 years old. Overall, 48% of ECLS was delivered for respiratory support and 52% was for cardiac support or extracorporeal life support to support cardiopulmonary resuscitation (ECPR). During the study period, over half of children were supported on ECLS with centrifugal pumps (51%) and polymethylpentene oxygenators (52%). Adverse events including neurologic events were common during ECLS, a fact that underscores the opportunity and need to promote quality improvement work.

Disclaimer: These guidelines for adult and pediatric anticoagulation for extracorporeal membrane oxygenation are intended for educational use to build the knowledge of physicians and other health professionals in assessing the conditions and managing the treatment of patients undergoing ECLS / ECMO and describe what are believed to be useful and safe practice for extracorporeal life support (ECLS, ECMO) but these are not necessarily consensus recommendations. The aim of clinical guidelines are to help clinicians to make informed decisions about their patients. However, adherence to a guideline does not guarantee a successful outcome. Ultimately, healthcare professionals must make their own treatment decisions about care on a case-by-case basis, after consultation with their patients, using their clinical judgment, knowledge and expertise. These guidelines do not take the place of physicians’ and other health professionals’ judgment in diagnosing and treatment of particular patients. These guidelines are not intended to and should not be interpreted as setting a standard of care or be deemed inclusive of all proper methods of care nor exclusive of other methods of care reasonably directed to obtaining the same results. The ultimate judgment must be made by the physician and other health professionals and the patient in light of all the circumstances presented by the individual patient, and the known variability and biological behavior of the clinical condition. These guidelines reflect the data at the time the guidelines were prepared; the results of subsequent studies or other information may cause revisions to the recommendations in these guidelines to be prudent to reflect new data, but ELSO is under no obligation to provide updates. In no event will ELSO be liable for any decision made or action taken in reliance upon the information provided through these guidelines.

Prophylactic PDC, with or without dialysis, did not decrease the time to achieve a negative fluid balance after the Norwood procedure, did not alter physiological variables postoperatively, and was associated with more severe adverse events.

Unfractionated heparin (UFH) is required in children on extracorporeal life support (ECLS) to maintain circuit patency. When high-dose UFH is inadequate to maintain an anticoagulant effect, the addition of antithrombin concentrate (ATC) is considered. The objective of this study was to review clinical experience giving 1,000 units (U) of ATC to patients on ECLS and UFH anticoagulation. Specifically, antithrombin (AT) levels pre- and post-administration of high-dose ATC, estimation of the efficacy of high-dose ATC administration as measured by the level of anticoagulation, and the incidence of adverse effects were determined. A retrospective chart review of all infants and children on ECLS who received ATC between June 2008 and May 2011 at Stollery Children's Hospital, Edmonton, Canada, was performed. A total of 78 doses of ATC were administered to 36 patients with a median age of 2.9 months (interquartile range, 0.6-12.6) on ECLS. Mean dose of ATC was 241 U/kg (95% confidence interval, 199-283). Mean AT level pre- and post-administration was 0.40 and 0.93 U/ml, respectively. Mean anti-Xa level pre- and post-AT administration was 0.23 and 0.41 U/ml, respectively. There were no associated acute adverse events. The administration of high-dose ATC decreases UFH dose requirements.
