Question:
My child had an Atrial Septal Defect (ASD) procedure about a week ago and was discharged. They have been doing well, but today at kindergarten, they developed a fever of 37.5°C. If it's just a cold, can I simply take them to a general clinic and mention that they are taking Aspirin? What if it's the flu? I am very worried about how to handle this.
Answer:
It is completely understandable that you are extra concerned while your child is recovering from a heart procedure.
Current Situation Summary:
• About a week has passed since the Atrial Septal Defect (ASD) procedure.
• Your child is currently taking Aspirin.
• A mild fever of 37.5°C started shortly after arriving at kindergarten today.
What to Do at Home:
• Offer water or electrolyte drinks frequently in small amounts to prevent dehydration.
• Dress your child in light clothing and keep the indoor temperature comfortable.
• Continue administering Aspirin exactly as prescribed by the pediatric cardiologist. Do not stop it without consulting them.
• If your child is uncomfortable due to the fever, you can give a fever reducer (Acetaminophen is recommended).
Managing a Cold vs. the Flu:
• If it's a cold: You can visit a general pediatrician. You must explicitly inform them, "My child had a heart procedure a week ago and is currently taking Aspirin."
• If the flu is suspected (high fever, muscle aches, rapid worsening of symptoms): Antiviral medications may be considered, but you must check with the pediatric cardiologist to confirm whether the specific antiviral is safe to take alongside Aspirin.
When to Seek Immediate Medical Evaluation:
• The fever reaches 38.5°C or higher and does not respond to fever reducers.
• Your child experiences difficulty breathing, chest pain, or severe lethargy.
• There is no urine output for more than 8 hours.
• You notice swelling, pain, or bleeding at the procedure site (usually the groin or arm).
Communicating with the Pediatric Cardiologist:
Since the fever occurred within a week of the procedure, it is highly recommended to notify your pediatric cardiology team first. They need to evaluate the possibility of a post-procedure infection, determine if antibiotics are necessary, and decide if any adjustments to the Aspirin dosage are required.
Start by ensuring adequate hydration and closely monitoring your child's condition. If the fever continues to rise or your child's overall condition worsens, please take them for an in-person medical evaluation immediately.
