What is brue?

What are the symptoms of a brief resolved unexplained event (BRUE) in infants?

The symptoms of a BRUE start and end suddenly.

During a BRUE, your baby may:

  • Turn blue or pale around the face, belly, or back.
  • Have trouble breathing, like breathing too slowly or too quickly.
  • Become stiff or floppy in their body.
  • Seem too sleepy or pass out (lose consciousness).

How is a brief resolved unexplained event (BRUE) in infants treated?

Your baby probably won't need any treatment. Most babies who have a BRUE won't need a stay in the hospital or any further testing.

How is a brief resolved unexplained event (BRUE) in infants diagnosed?

A BRUE usually isn't diagnosed with testing. Instead, to find out if your baby had a BRUE, the doctor will:

  • Ask about the changes you saw in your baby.
  • Do a physical exam.
  • Ask about your baby's health and the health of family members.

If the doctor can't find a cause for your baby's symptoms, then your baby is diagnosed with a BRUE.

How can you care for your infant after a brief resolved unexplained event (BRUE)?

Work with your doctor to make a plan that keeps your baby healthy, happy, and safe.

Here are some steps you can take:

  • Be sure to go to all follow-up appointments.
  • Learn how to do CPR and rescue breathing. It's important to know this in case your baby stops breathing. To find a CPR course near you, call your local hospital or the local branch of the Red Cross or American Heart Association.
  • Always put your baby to sleep on their back, not on their side or tummy. Put your baby in a crib or bassinet in your bedroom for the first 6 months. Keep soft items like stuffed animals, pillows, and blankets out of the crib. Use a firm mattress with a fitted sheet. Don't use sleep positioners, head-shaping pillows, or bumper pads.
  • Make sure that your baby gets regular checkups and recommended vaccines to protect against serious illness.

What is a brief resolved unexplained event (BRUE) in infants?

A brief resolved unexplained event (BRUE) is a sudden change in how your baby breathes, looks, or responds. For example, your baby may start to have trouble breathing, or your baby's skin may turn blue or pale. It can be scary to see this happen. But the change is brief—usually less than a minute—and your baby quickly gets better.

Why a BRUE (say "broo") happens isn't known. It can't be explained by another problem, such as an illness, infection, or injury.

In most cases after a BRUE, your baby doesn't need tests or a stay in the hospital.
