ULTRA Trial Summary

This trial is studying two different types of ultrafiltration to see which is better at improving post-operative outcomes for infants and children who have had heart surgery.

Who is the study for?
This trial is for children with congenital heart disease weighing between 2.5 to 15kg, who are scheduled for cardiac surgery requiring cardiopulmonary bypass. Parents or guardians must consent to participate. It excludes those over 15kg (with some exceptions), without planned CPB use, isolated ASD repair, severe blood disorders, certain genetic syndromes with immune dysfunction, immunodeficiency syndromes, and severe liver or kidney disease.Check my eligibility
What is being tested?
The study tests two ultrafiltration protocols during heart surgery in kids: high-exchange (60ml/kg/hr) versus low-exchange (6ml/kg/hr). The goal is to see which better reduces inflammation from the heart-lung machine used in surgery and improves recovery outcomes.See study design
What are the potential side effects?
Ultrafiltration side effects may include shifts in fluid balance that could affect organ function temporarily. However, this procedure aims to reduce complications related to inflammation after using a heart-lung machine.
