Cupriavidus pauculus Infection Associated With Extracorporeal Membrane Oxygenation in a Pediatric Patient

We describe a critically ill neonate in the postoperative period of complex cardiovascular surgery who required extracorporeal membrane oxygenation (ECMO) and developed bacteremia caused by <i>Cupriavidus pauculus</i>. This uncommon infection in pediatric patients associated with ECMO highlights the diagnostic suspicion of bacteremia due to this non-fermentative Gram-negative bacillus. The report emphasizes early clinical evaluation and treatment and underscores the need for strict protocols to disinfect ECMO circuits, alerting health institutions to the potential transmission risk through these systems.
