Question:

My baby had a high fever and projectile vomited while coughing, so we went to the hospital. The doctor suspected a urinary tract infection (UTI) and performed a urine test, but it came back negative. We were told it is a feverish cold and were prescribed medication. However, when I give the baby medicine after a formula feeding, they cough and projectile vomit again. Could this actually be enteritis (stomach flu)? Should we go back to the clinic for another evaluation?

Answer:

I understand it can be very distressing to see your baby experience a high fever and projectile vomiting.

Current Assessment:

• Projectile vomiting triggered by a coughing fit is actually a very common reaction in infants.

• The physical stimulation of a severe cough can easily trigger the gag and vomiting reflex.

• Because of this, it is highly likely that the vomiting is a symptom related to the cold rather than enteritis (a stomach flu).

Things to Monitor at Home:

Please observe the following to ensure your baby is recovering safely:

1. Vomiting frequency: Note whether the vomiting only happens when taking medication or if it occurs randomly throughout the day.

2. Diarrhea: Check for loose, watery stools occurring more than three times a day.

3. Signs of dehydration: Look out for a lack of tears when crying or significantly fewer wet diapers than usual.

Tips for Administering Medication:

To help prevent vomiting when giving medicine, try the following steps:

• Wait about 30 minutes after a formula feeding before giving the medicine to let the stomach settle.

• Divide the medication into 2 to 3 smaller portions and administer it very slowly.

• Wait until a coughing spell has completely calmed down before attempting to give the dose.

When to Seek Immediate Medical Attention:

Please visit a doctor for a re-evaluation if you notice any of the following warning signs:

• The baby vomits 5 or more times in a day.

• There is no urination (dry diapers) for over 8 hours.

• Persistent vomiting is accompanied by diarrhea.

• The baby appears extremely lethargic, weak, or unresponsive.

For now, it is appropriate to observe your baby at home while following these feeding and medication tips. However, if the vomiting continues to repeat frequently despite these changes, or if any new symptoms develop, please visit your pediatrician for a follow-up examination tomorrow.
