Could a common heart drug fix a rare surgery complication in kids?
NCT ID NCT06833320
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether propranolol, a drug often used for high blood pressure, can safely treat chylothorax—a buildup of lymphatic fluid—in children after open heart surgery. About 50 children aged 7 days to 18 years with congenital heart disease will receive either propranolol or a placebo. The goal is to see if the drug helps resolve the fluid leak faster and to identify which patients benefit most.
