Insights
Extracorporeal membrane oxygenation (ECMO) in children with heart disease and genetic syndromes shows similar survival and length of stay compared to those without syndromes. Renal issues impacted mortality in the genetic group, but ECMO remains a viable option.
Area of Science:
- Pediatric Cardiology
- Medical Genetics
- Critical Care Medicine
Background:
- Extracorporeal membrane oxygenation (ECMO) is a life-support measure for critically ill patients.
- Genetic syndromes can complicate cardiac conditions in children.
- Outcomes of ECMO in pediatric patients with both heart disease and genetic syndromes require further evaluation.
Purpose of the Study:
- To assess the morbidity and mortality associated with ECMO in children with congenital heart disease and genetic syndromes.
- To compare ECMO outcomes between children with and without genetic abnormalities.
Main Methods:
- Retrospective review of pediatric patients undergoing ECMO from January 2000 to March 2012.
- Data collection included demographics, medical history, organ dysfunction, and outcomes (length of stay, survival).
- Comparison of outcomes between children with and without genetic syndromes.
Main Results:
- 43 ECMO runs in children with genetic syndromes versus 334 without.
- Children with genetic syndromes were older at cannulation.
- Hospital length of stay and mortality rates were similar between groups.
- Renal insufficiency and dialysis need were associated with mortality in the genetic group.
- 56% of children with genetic syndromes survived to hospital discharge, with 10 patients alive at follow-up.
Conclusions:
- ECMO is a feasible treatment for children with heart disease and genetic syndromes.
- Survival rates are comparable, and complication rates are low.
- Careful monitoring for renal complications is crucial in this patient population.
Abstract:
Our objective was to evaluate morbidity and mortality associated with extracorporeal membrane oxygenation (ECMO) in children with genetic syndromes and heart disease. We conducted a retrospective review of all children with heart disease and genetic syndromes receiving ECMO during the period January 2000 and March 2012 at Arkansas Children's Hospital, Little Rock. The medical charts were reviewed to obtain the following variables: demographic information, medical and surgical history, laboratory and microbiological, information on organ dysfunction, and outcome characteristics. The outcome variables evaluated in this report included: hospital length of stay (LOS), survival to hospital discharge, and current survival. Outcome data were compared among critically ill children with and without syndromes. During the study period, there were 377 ECMO runs in 336 children with heart disease. Of these, 43 ECMO runs occurred in children with genetic syndromes whereas 334 ECMO runs occurred in children with no genetic abnormality. Children in the group with underlying genetic syndrome were older at the time of ECMO cannulation than the group with no syndrome. During the ECMO run, hospital LOS and mortality were similar in children with and without underlying genetic abnormality. Among genetically abnormal patients, renal insufficiency and need for dialysis were associated with mortality. In this group, 24 patients (56%) were discharged alive. However, only 10 patients are living to date in this cohort. ECMO can be used in children with heart disease and genetic syndromes with good results. The survival rate is high and the complication rate is low.
