The emergency department treats everything from broken bones to small abrasions to headaches. No matter is too small, and no patient is turned away. At Mission Hospital ED, in partnership with CHOC at Mission Hospital, patients and families have access to:

  • Pediatric-trained nurses and emergency physicians
  • Pediatric specialists
  • In-house pediatrician & neonatologist available 24/7
  • Waiting room just for kids
  • Pediatric emergency response team
  • Child life specialists to provide comfort and distraction at the bedside


We know trips to the ER aren’t planned in advance, but if you are able, make sure you have everything necessary for an ED visit. Learn about what to bring to the ED.

When should I take my child to the emergency department?

Knowing when a child’s condition reaches a level in which it needs emergency care can be difficult. After all, children are not small adults. They might display different symptoms than adults, and some symptoms that aren’t serious for an adult can be very serious – even dangerous – for children.
Please call 911 immediately if your child needs immediate medical attention and you cannot safely transport your child to the hospital.
Staff members at CHOC advise parents to follow their parental instincts. Your child should be taken to the ED when:
• They are experiencing rapid and fast breathing, head trauma, trauma with loss of consciousness or vomiting, motor vehicle accidents, severe abdominal pain or dehydration.
• An infant less than 28 days old has a fever of 100.4 degrees or higher.

Pediatric Trauma Center

CHOC and Mission Hospital together provide the only Level II pediatric tauma center in South Orange County. Our dedicated team knows that children are not small adults, and staff members have special training in treating kids.

To be designated as a trauma center by the American College of Surgeons, CHOC and Mission Hospital fulfilled strict criteria to provide the highest quality of care to meet all pediatric patients’ needs. The trauma center provides 24-hour coverage by board-certified trauma surgeons. In addition, there is quick access to specialties including orthopedic surgery, neurosurgery, anesthesiology, radiology and critical care.

Child Life

When children arrive at the hospital, they are often crying, nervous or anxious. Often times, children fear what will happen once they are being treated.

What is child life?

The child life specialists help make the hospital experience less stressful and frightening by making kids feel comfortable using special play techniques. Child life is a very important part of what makes CHOC one of the most unique hospital experiences.

How can they help my child?

Child life specialists also help patients understand how the medical team administers a care plan or treatment with special teaching tools. To help patients understand and prepare for their care, child life specialists use books, practice dolls, pictures and play medical equipment. During procedures, children can watch a movie on a tablet, play a game or engage in other fun activities.
