Heart Defect Repair: Before Your Child's Surgery

The heart

What is heart defect repair?

Heart defect repair is surgery to fix a heart problem that prevents blood from flowing normally through the heart. The doctor will make a large cut (incision) in your child's chest. The incision usually is made through the breastbone (sternum). But some types of heart defects are repaired through an incision in the side of the chest between the ribs. The doctor will connect your child to a machine that does the jobs of the heart and lungs (heart-lung bypass machine). This machine will allow the doctor to stop your child's heartbeat while the doctor works on the heart.

After the heart is repaired, the doctor will restart your child's heartbeat and disconnect the heart-lung machine. Then the doctor will use stitches to close the incision in your child's chest.

Some heart defects can be repaired with one surgery. But it is possible that your child may need more than one surgery to fix the defect.

Your child will probably spend about 5 days in the hospital.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

What happens before surgery?

Preparing for surgery

  • Bring a list of questions to ask your child's doctors. It is important that you understand what surgery is planned, the risks, benefits, and other options.
  • A simple explanation should be given to your child before the surgery. Depending on your child, this should be done a day or two before surgery for children age 5 years and younger, and up to a week before surgery for older children.
  • Tell your doctor ALL the medicines, vitamins, and natural health products your child is taking. Keep a list of these with you, and bring this with you to your child's appointments. You will be told which medicines to give your child before surgery.
  • Tell your doctor or nurse about any allergies your child has to medicines or latex.
  • Some medicines, such as aspirin or ibuprofen (Advil, Motrin), and certain vitamins or natural health products can increase the risk of bleeding or interact with anesthesia. Your child may be asked to stop these medicines before surgery.
  • Before the operation, you will speak with a member of the anesthesia team to discuss anesthetic options, including the risks, benefits, and alternatives to each. This may be on the phone, or in person.
  • Ask if a special tour of the operating area and hospital is available.

Taking care of your child before surgery

  • Build healthy habits into your child's life.
    • Help your child to stay as active as possible.
    • Teach about and support a healthy diet.

Having surgery can be stressful both for your child and for you. This information will help you understand what you can expect and how to safely prepare for surgery.

What happens on the day of surgery?

  • Follow the instructions exactly about when your child should stop eating and drinking, or the surgery may be cancelled. If the doctor has instructed you to have your child take his or her medicines on the day of surgery, please have your child take the medicine using only a sip of water.
  • See that your child has bathed. Do not apply lotions or deodorant.
  • Your child may brush his or her teeth. Remind your child not to swallow any toothpaste or water.
  • Be sure your child has something that reminds him or her of home. A special stuffed animal, toy, or blanket may be comforting. For an older child, it might be a book or music. Leave any valuable items at home.

At the hospital or surgery centre

  • A parent or legal guardian must accompany your child.
  • Your child will be kept comfortable and safe by an anesthesia provider. Your child will be asleep during the surgery.
  • Before your child's surgery, the doctors or nurses will ask you to repeat your child's full name and what surgery he or she is having. This makes sure that the correct part and side of the body will be operated on. The area for surgery may be marked.
  • A small intravenous (IV) tube is usually placed in a vein, to give fluids and medicines. This tube may be placed in the pre-op area or in the operating room after your child is asleep. Because of the medicines given, your child may not remember much about the operating room.
  • After the surgery, your child will be taken to the recovery room.
  • Before your child wakes up, the doctor will probably talk to you about the surgery. When your child wakes up in the recovery room, the nurse will check his or her vital signs (temperature, blood pressure, pulse rate, and breathing) and make sure that your child is comfortable. You will be allowed to see your child as soon as he or she wakes up.
  • Your child may have a breathing tube down his or her throat. This is usually removed within 12 hours after surgery.
  • Your child will have chest tubes to drain fluid and blood after surgery. The fluid and extra blood are normal and usually last only a few days. The chest tubes are usually removed in 1 to 2 days.
  • Your child will have several thin wires coming out of his or her chest near the incision. These wires can help keep your child's heartbeat steady after surgery. They will be removed before your child goes home.

Going home

  • Follow your doctor's instructions about when your child can do intense exercise, such as sports, running, or physical education.
  • When you leave the hospital, you will get more information about how to take care of your child at home.

When should you call your doctor or nurse call line?

  • You have questions or concerns.
  • You don't understand how to prepare your child for the surgery.
  • Your child becomes ill before the surgery (such as fever, flu, or a cold).
  • You need to reschedule or have changed your mind about your child having the surgery.
