Baby blood test may predict surgical recovery
NCT ID NCT06731855
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study measures two natural amino acids, arginine and ADMA, in newborns who had abdominal surgery within their first 5 days of life. Researchers want to see if the balance of these substances can help predict how quickly a baby recovers and whether complications arise. No extra blood draws are needed—only leftover samples from routine tests are used. The goal is to gather information that could lead to future treatments to improve recovery.

Who is studied
The study population with be of 30 infants born \>35 weeks gestation and has a condition requiring major gastrointestinal surgery within 5 days (120 hours) of birth. This is expected to include predominantly congenital gut malformations: gastroschisis, gut atresias, volvulus and congenital diaphragmatic hernia (who are stable enough for surgery in this time frame). Patient will be recruited over a 1 year period. These infants will be born at Liverpool Women's Hospital or at their local hospital in the north west of England region, and transferred to Alder Hey Children's Hospital for their operation, either directly or via Liverpool Women's Hospital Neonatal Intensive Care Unit. They will recover in Alder Hey Children's Hospital's Paediatric Intensive Care Unit or Neonatal Surgical Unit and may later be transferred back to Liverpool Women's Hospital.
