Yes. Even though the heart or lung disease is better now, your child may have significant exposure to low oxygen levels prior to ECMO. This places your child at higher risk for developmental problems. These potential problems can be determined only as your child grows. We suggest that your child be brought to a follow-up clinic here or near your home. Your ECMO coordinator will talk to you about your follow-up care before you leave our hospital. They will also be able to answer your questions about this process.
