Delirium is a sudden change in the way a patient thinks, feels, or behaves that is caused by a medical condition or treatment. Delirium can cause your child to be confused, agitated, or sleepy. They may have trouble understanding what is happening around them or might see or hear things that are not actually there.
Delirium that is not treated can cause you and your child more distress and confusion. It can increase your child’s risk of injury or death. Delirium can interfere with treatment or cause your child to stay in the hospital longer.
Treatment for delirium includes addressing the causes of the delirium, giving medicines, or controlling the patient’s surroundings.
Let a care team member know if you notice an unusual change in your child’s thoughts, emotions, personality, or behavior. If your child has delirium, they might:
Possible causes of delirium for children who are sick or in the hospital include:
Your care team will watch your child’s behavior closely. This includes checking if your child is confused, restless, or has other signs of delirium.
Delirium can come and go quickly. Sometimes, it can last several days or weeks. Treating delirium often involves finding the main causes and treating them. The care team can do things to help your child, including giving medicines and changing their surroundings if needed. Your child’s doctor may ask the mental health care or psychiatry team to help treat your child’s delirium.
Mental health care providers are trained to find the causes of delirium and help stop it or keep it from getting worse. For example, a psychiatrist can prescribe medicine to treat delirium symptoms. They can also check your child’s regular medicines to learn if any of them could cause delirium.
Delirium does not mean your child is mentally ill. It means their physical illness is affecting their thinking, behavior, or emotions.
Up to 7 out of 10 patients in the pediatric intensive care unit (PICU) have a sudden change in their thinking and alertness. Delirium in the hospital can be caused by many things, such as being very sick, lack of sleep, and certain medicines.
Patients are at higher risk of delirium if they:
The PICU nurses will regularly check your child for delirium. Please let your care team know if your child seems confused or agitated.
Try these strategies to help your child. You can remember them with the words “CARES FOR.”
Speak clearly and slowly. Use simple words or phrases. Repeat things as needed.
Try to keep usual activities, and encourage your child to do things for themselves if possible. Avoid using physical restraints, such as using a “seat belt” to keep them in bed.
Remind your child where they are, who you are, and what day and time it is. “Re-orient” means to remind them, even if you think they should know. For older children, have a clock or calendar where they can see it.
To help your child stay focused, avoid having lots of things happening around them at the same time. Make sure your child’s room is light during the day and dark at night. Try to keep the room quiet when your child is calm or resting. Avoid having the TV on when your child is not watching. If your child wears glasses or hearing aids, make sure they have them.
Try to keep a regular day-night routine. Help your child stay awake most of the day if possible. Your child might not always stay awake during the day because of medicines or procedures. But sleeping less during the day helps your child sleep more at night.
Give your child familiar things, such as a favorite comfort item or toy. Play soothing music they know. Bring pictures or objects from home to your child’s room. Avoid having visitors your child does not know well. Ask your care team if the same staff members can care for your child as much as possible.
Encourage movement and mobility. Help your child sit up in bed, get out of bed, and walk around as much as possible. Be aware that delirium can increase your child’s risk of falls. Read more about early mobility in the ICU.
Reassure and comfort your child. Speak to your child in a calm and soothing manner. Tell them they will be OK and that they are safe. Let them know you or another loved one will stay with them.
If you believe your child may have delirium or your child has an unusual change in behavior, tell your doctor or nurse as soon as possible.
If you have questions about delirium, please speak with your care team.
