Left Ventricle Decompression Strategies in Pediatric Peripheral Extracorporeal Membrane Oxygenation
Background: Extracorporeal membrane oxygenation (ECMO) is widely used in patients with potentially reversible acute cardiac and/or pulmonary failure who are unresponsive to conventional treatment.

Summary: | Background: Extracorporeal membrane oxygenation (ECMO) is widely used in patients with potentially reversible acute cardiac and/or pulmonary failure who are unresponsive to conventional treatment. Patients with profound left ventricular (LV) dysfunction under venous-arterial (V-A) ECMO may experience LV distention, pulmonary edema, and thrombus formation. It is critical to unload the left ventricle to prevent such complications. The aim of this study was to identify the risks, timing and methods of LV decompression in pediatric peripheral ECMO. Methods: Between August 2006 and November 2017, 51 patients received peripheral ECMO support in our pediatric intensive care unit. All of them were less than 18 years of age and non-cardiotomy surgery-related. We retrospectively reviewed the patients' clinical presentations, decompression methods and outcomes. Results: The overall success rate of ECMO removal was 76.5% (39/51), and the survival rate after discharge was 62.7% (32/51). The myocarditis group had the most favorable outcomes among the ECMO patients (100% survival). LV decompression was needed in 12 patients who had profound LV dysfunction under V-A ECMO. Five patients received medical treatment successfully, and the other 7 patients underwent intra-aortic balloon pump (IABP) procedures. In the IABP group, 1 patient still needed further pigtail-decompression. All of our decompression patients survived with good neurological outcomes (Glasgow Outcome Scale 5). Conclusions: The patients with profound LV dysfunction under peripheral VA ECMO were at risk of thromboembolic events and LV decompress was needed. If medical decompression fails, IABP is a feasible approach for LV decompression in pediatric peripheral ECMO. |
