Outcomes after extracorporeal cardiopulmonary resuscitation (ECPR) following refractory pediatric cardiac arrest in the intensive care unit

AimTo describe our experience using extracorporeal cardiopulmonary resuscitation (ECPR) in resuscitating children with refractory cardiac arrest in the intensive care unit (ICU) and to describe hospital survival and neurologic outcomes after ECPR.MethodsA retrospective chart review of a consecutive case series of patients requiring ECPR from 2001 to 2006 at Arkansas Children's Hospital. Data from medical records was abstracted and reviewed. Primary study outcomes were survival to hospital discharge and neurological outcome at hospital discharge.ResultsDuring the 6-year study period, ECPR was deployed 34 times in 32 patients. 24 deployments (73%) resulted in survival to hospital discharge. Twenty-eight deployments (82%) were for underlying cardiac disease, 3 for neonatal non-cardiac (NICU) patients and 3 for paediatric non-cardiac (PICU) patients. On multivariate logistic regression analysis, only serum ALT (p-value = 0.043; OR, 1.6; 95% confidence interval, 1.014–2.527) was significantly associated with risk of death prior to hospital discharge. Blood lactate at 24 h post-ECPR showed a trend towards significance (p-value = 0.059; OR, 1.27; 95% confidence interval, 0.991–1.627). The Hosmer–Lemeshow tests (p-value = 0.178) suggested a good fit for the model. Neurological evaluation of the survivors revealed that there was no change in PCPC scores from a baseline of 1–2 in 18/24 (75%) survivors.ConclusionsECPR can be used successfully to resuscitate children following refractory cardiac arrest in the ICU, and grossly intact neurologic outcomes can be achieved in a majority of cases.
