What to Know About Your Child's Stay in the Pediatric Intensive Care Unit

Medically Reviewed by Dany Paul Baby, MD on April 21, 2022

What is the PICU? The PICU (pediatric intensive care unit) is the unit of a hospital that provides the highest amount of care to children. It is similar to the ICU (intensive care unit), where adults receive special care, but the staff in the PICU specializes in working with children. 

The equipment available in the PICU is best suited for children, and the environment may be more child-friendly in general. This unit provides a level of care that is generally not available in other areas of the hospital.

Who Receives Care in the Pediatric Intensive Care Unit?

PICU patients include newborn babies, toddlers, children, pre-teens, and teenagers. Most PICU patients are 18 years old or younger. However, people with certain conditions may require the services of the PICU even if they are over 18 years old.

Some hospitals have an ICU specifically for newborn babies that is separate from the PICU, called a NICU (neonatal intensive care unit). In hospitals without a NICU, though, sick newborns and infants are cared for in the PICU.

Children who are critically ill come to the PICU to receive care and attention. Common reasons for children to go to the PICU include:

  • Surgery aftercare
  • Lung & breathing issues
  • Accidental injury
  • Severe infection
  • Diabetes complications
  • Organ failure
  • Cancer
  • Epilepsy

How Long Do Children Usually Stay in the PICU?

The answer to this question depends on your child's condition. Some kids stay in the PICU for a day or two. Others stay for weeks or months. 

However, longer stays are pretty rare. One study showed that only between 1% and 4.7% of children in the PICU stayed for longer than 12 days.

Who Works in the PICU?

All of the staff members who work in the PICU specialize in children's intensive care. They include:

PICU nurses. A pediatric intensive care unit nurse works closely with you and your child. PICU nurses usually have fewer patients to care for at one time than nurses in other departments, so they spend more time with each child. They are the ones delivering general care to your child.

PICU attending. The attending physician is a doctor who oversees the department and is responsible for overseeing your child's care. In the PICU, the attending is often a pediatric intensivist. These types of doctors have had specialized training in both pediatrics and intensive care.

PICU residents and fellows. Residents are doctors-in-training. They are MDs and have graduated from medical school but are now practicing a specialty. Residents in the PICU are usually training to become pediatricians. Fellows are already pediatricians, and they are participating in further training to become pediatric intensivists.

Other doctors. Many other specialists may be involved in your child's care depending on their needs and condition. Other types of doctors you might meet in the PICU include cardiologists, neurologists, pulmonologists, and more.

Physical therapists. Pediatric physical therapists work with children who need help with their mobility. They use playful, child-friendly methods to help kids improve their range of motion, strength, and flexibility.

Occupational therapists. Even though kids don't have jobs, they can still benefit from occupational therapy! Pediatric occupational therapists help children learn the skills they need to engage in age-appropriate activities independently. They strive to make their sessions feel like playtime to keep kids engaged and learning.

Social workers. In the PICU, a social worker may help your family find a place to stay while your child is in the hospital. They can also help with insurance problems and planning for when your child is ready to go home to make sure they will have all the care they need.

Child life specialists. Some PICUS have child life specialists. These professionals help kids to understand, at an age-appropriate level, what is happening or what is going to happen in the hospital.

What Is a Day in the PICU Like?

In the PICU, the medical care team meets daily to discuss each child's condition and care. This process is called the team's "rounds." During rounds, the team goes around the PICU to each patient to talk about any changes to their condition or care plan.

In some PICUs, family members must leave during rounds to protect other patients' privacy. Other hospitals offer "family-centered care." In these PICUs, family members are encouraged to stay during rounds and to actively participate in their children's care.

If you're not able to participate in rounds for any reason, the attending physician will call you or talk to you in person to discuss any important updates.

When your child is in the PICU, you may want to spend every moment there. However, experts recommend taking breaks to avoid getting too drained. Some hospitals allow parents to stay overnight with their children in the PICU, while others don't. Either way, some experts recommend going home to get a good night's rest so you can be fully refreshed to support your child.

At many hospitals, other visitors, including other relatives and siblings, can only visit during specified visiting hours. Additionally, some hospitals prevent other children from visiting during cold and flu season to avoid spreading germs that may be dangerous to people with a weakened immune system.

You may be asked to wear a mask or gloves while in the PICU to prevent the spread of germs.

What Equipment Do Doctors Use in the PICU?

Some children in the PICU need extra medical support. Doctors use machines and devices to help keep them stable. Some of the equipment you might see includes:

  • Intravenous catheters (IVs) and central lines. IVs deliver medication and fluid straight into your child's body. A central line is similar to an IV, but it supplies more volume. You may also see IV bags and tubing delivering metered doses of medication to children under observation.
  • Monitoring devices. Monitoring devices help doctors and nurses keep a close eye on heart rate, breathing, and blood pressure. Your child may have chest leads connected to a monitor that shows their rate of respiration and their heart rate. These leads are kept on with painless stickers and look like wires attached to the monitoring device. A pulse oximeter is a clip-on device put onto the finger or toe that measures the level of oxygen in the blood. Your child may also have a blood pressure cuff.
  • Breathing devices. When kids need extra help breathing, doctors may give them an oxygen mask or a nasal cannula to deliver extra oxygen. Some kids need mechanical breathing assistance. If your child needs a ventilator, your doctor will sedate them and then insert a tube into their windpipe and connect it to the ventilator to help them breathe.
  • Testing equipment. During your child's stay, they may need to undergo different medical tests. Imaging tests may include X-rays, MRIs, or ultrasounds. Lab tests may include urinalysis or blood testing. 

What Happens When Your Child Leaves the PICU?

Some kids go straight home from the PICU. Others go to another department of the hospital to receive less intensive care. Either way, getting discharged from the PICU means your child is starting to get better and is stable enough to leave. 

Ask the PICU staff any questions you have and see if you can work with a social worker to make sure you have everything ready for when your child comes home after staying in the PICU.
