Abstract
Introduction: The use of extracorporeal membrane oxygenation (ECMO) in children continues to increase nationally, including patients with methicillin-resistant Staphylococcus aureus (MRSA) infection. Survival of pediatric patients with MRSA sepsis has not improved over the last 20 years. We sought to review our institutional experience and outcomes of ECMO support among children with MRSA infection.
Methods: Children aged 0–19 years who received ECMO support from October 2014 to June 2021 were reviewed retrospectively. Patients with laboratory confirmed MRSA infections were identified.
Results: Out of 88 unique pediatric patients requiring ECMO support, eight patients had documented MRSA infections. The duration of mechanical ventilation prior to ECMO initiation was an average of seven days (range 0.7 to 21.8 days). The median ECMO duration was 648.1 h (range 15.5 to 1580.5 h). Five patients were successfully decannulated; however, only two patients survived to discharge. The two surviving patients were both cannulated via VV-ECMO. Mechanical ventilation prior to ECMO was 4.5 and 21.8 days in these cases with run durations of 18.9 and 29.9 days, respectively.
Conclusions: Our institutional survival of patients with MRSA on ECMO is lower than what has been reported in recent database studies, but notably, 62.5% were successfully decannulated. While both surviving patients were supported with VV-ECMO, there was no other clear trend in factors that contributed to survival. MRSA continues to be a source of significant morbidity and mortality among pediatric patients. On-going investigation of outcomes and factors contributing to survival in patients with MRSA infection on ECMO is warranted.
