Objective: To report our institutional experience of veno-arterial extracorporeal membrane oxygenation (VA ECMO) in children with refractory septic shock.
Materials and Methods: We retrospectively reviewed our ECMO database to identify patients who received VA ECMO for septic shock from January 2004 to June 2013 at our Pediatric Intensive Care Unit in Armand-Trousseau Hospital. We included all neonates and children up to the age of 18 years who received VA ECMO for septic shock. For each patient, we collected the pre-ECMO inotrope score, clinical circulatory and ventilatory parameters, infecting organism, ECMO duration and complications, and length of hospital stay.
Main Results: The study included 14 neonates and 8 older children (the pediatric population, with a mean age of 30 months, range: 1-113 months). Survival was 64% among newborns and 50% among pediatric patients. Multiorgan failure or severity scores did not show any correlation with mortality (Pediatric Logistic Organ Dysfunction score, P = 0.94; the score for neonatal acute physiology-perinatal extension II, P = 0.34). In the pediatric population, the inotrope score was higher in the survivor group (127.5 vs. 332.5, P = 0.07). Blood samples taken shortly before cannulation showed that pH (P = 0.27), lactate level (P = 0.33), PaO2/FiO2 ratio (P = 0.49), or oxygenation index (P = 0.35) showed no correlation to success or failure of ECMO.
Conclusion: ECMO can be safely used to resuscitate and support children with refractory septic shock. We recommend that patients with oliguria whose lactate level has not decreased within 6 h of starting maximum drug therapy be transferred to an ECMO referral center.
