In a neonate with trisomy 21 and an AV canal defect, if vital signs are stable, what is the initial management?

• A. Immediate Surgical Intervention
• B. Observation and Follow-Up
• C. Initiate Diuretics and Supplemental Oxygen
• D. Start Antibiotics

Answer: (B)

When a neonate with a congenital heart defect is hemodynamically stable, the initial approach is watchful waiting with close follow-up rather than rushing to surgery. In an AV canal defect associated with Down syndrome, the defect often creates increased pulmonary blood flow, but if the infant shows no signs of heart failure or poor growth, there’s time to monitor and plan definitive repair for a safer window in early infancy rather than performing urgent intervention right away. Vigilance means watching for feverish signs, feeding difficulties, rapid breathing, or failure to thrive, which would prompt medical management for heart failure and earlier surgical consideration.

Medical therapy like diuretics and supplemental oxygen is reserved for children showing congestive heart failure symptoms, not for a stable neonate. Antibiotics aren’t part of routine management for this defect unless an infection is present.
