Hepatic Portoenterostomy in Infants

  • Medicines can prevent or treat a bacterial infection or help decrease your child's pain.
  • Give your child's medicine as directed. Contact your child's healthcare provider if you think the medicine is not working as expected. Tell him or her if your child is allergic to any medicine. Keep a current list of the medicines, vitamins, and herbs your child takes. Include the amounts, and when, how, and why they are taken. Bring the list or the medicines in their containers to follow-up visits. Carry your child's medicine list with you in case of an emergency.
  • Do not give aspirin to children under 18 years of age. Your child could develop Reye syndrome if he takes aspirin. Reye syndrome can cause life-threatening brain and liver damage. Check your child's medicine labels for aspirin, salicylates, or oil of wintergreen.

Follow up with your child's healthcare provider as directed:

Your child may need to return to have his stitches or staples removed. Write down your questions so you remember to ask them during your child's visits.

Feeding your child:

You may need to meet with a dietitian to make sure your child is getting enough calories and nutrition. Your child may need vitamin supplements or high-calorie formula. Ask about breastfeeding. If your child is able to eat foods, ask about giving him mashed fruits, vegetables, or other baby foods.

Care for your child's wound as directed:

When you are allowed to bathe your child, carefully wash his wound with soap and water. Dry the area and put on new, clean bandages as directed. Change your child's bandages when they get wet or dirty.

  • Your child has a fever.
  • Your child's wound is red, swollen, or draining pus.
  • Your child is irritable and crying more than usual.
  • Your child is weak or sleeps more than usual.
  • You have questions or concerns about your child's condition or care.

Seek care immediately or call 911 if:

  • Your child has trouble breathing.
  • Your child has a seizure.
  • Your child's skin or eyes are more yellow than before surgery.
  • Your child is urinating less or not at all.
