Kawasaki Disease


Kawasaki disease (KD) is an illness in children that causes fever and inflammation of blood vessels. KD can damage blood vessels in your child's heart and lead to life-threatening heart problems, such as a heart attack. The exact cause of KD is unknown. Healthcare providers believe it may be caused by a bacterial or viral infection.


Informed consent

is a legal document that explains the tests, treatments, or procedures that your child may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your child's medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done to your child. Make sure all of your questions are answered.


  • Aspirin helps prevent blood clots. Aspirin may cause your child to bleed or bruise more easily.
  • Anticoagulants help prevent blood clots. Blood thinners may cause your child to bleed or bruise more easily.
  • Immune globulin may be given to help your child's immune system fight his infection.
  • Immune therapy may be given to decrease damage to your child's blood vessels.
  • Antibiotics help treat or prevent a bacterial infection.


  • Blood and urine tests give information about your child's overall health, such as his liver and kidney function. These tests will also show if your child has an infection.
  • Telemetry is continuous monitoring of your child's heart rhythm.
  • An x-ray, echocardiogram, CT scan, or MRI may be used to help healthcare providers see your child's heart and blood vessels. Your child may be given contrast dye before these tests. Tell the healthcare provider if your child has ever had an allergic reaction to contrast dye. Do not let your child enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if your child has any metal in or on his body.


Surgery may be needed to increase blood flow or replace blocked blood vessels.


  • Your child may bleed too much during surgery. He may also get an infection after surgery. Even with treatment, your child may have heart problems from KD later in life.
  • Left untreated, KD may cause damage to the blood vessels in your child's heart. This damage can lead to life-threatening heart problems, such as a ruptured blood vessel or a heart attack.


You have the right to help plan your child's care. Learn about your child's health condition and how it may be treated. Discuss treatment options with your child's caregivers to decide what care you want for your child.
