Kids and Emergency Care


When it comes to children, a level of unique and specialized care is necessary. “There are a number of considerations in children you have to focus on, whether dealing with an infant, a neonate (less than 28 days old), a child or an adolescent,” says Dr. Pierog. “There are many different features that are obvious, as well as those from a physiological standpoint that determine how their systems function,” says Dr. Pierog.


“Kids are much more prone to have facial and intracranial (brain) injuries than adults because of their larger head-to-body size. Because of their propensity to fall, we see a higher number of upper extremity injuries such as wrist and elbow fractures,” says Dr. Pierog. In addition, because they have a higher hydration requirements, children need two to three times as much fluid than do adults.


“Children require special treatment, not just for their size, but also when it comes to the equipment needed to treat their conditions,” says Dr. Pierog. CHOC’s emergency department has all the bases covered, including master’s prepared child-life specialists who are trained to understand and treat the emotional and physiological needs of little ones. “There are a number of features that pediatric emergency physicians are aware of and prepared to treat, including respiratory, gastrointestinal, and environmental conditions, such as pesticide exposure from children putting items in their mouths.”


For adults, medication dispensing is generalized, but not for children. To ensure parents are giving the right amount, pay attention to the levels. “The dosages of common medications are going to be on a weight-based formula,” says Dr. Pierog.

Kids and Concussions
“The word concussion comes from the Latin word to shake violently. It’s a force that causes a temporary injury to the brain or spinal cord,” says Dr. Taraman. “A lot of times, people may hit their head and don’t realize it was a concussion.”

Kids and Stomachaches
So what causes tummy trouble? It can be as specific as an ulcer, a dietary issue, pneumonia or a sinus infection. Stomachaches are extraordinarily common. Although always a concern, the majority of kids with abdominal pain do not require urgent intervention.

Overscheduled Kids
“There are a number of studies that suggest kids actually do need some unstructured time,” says Dr. Heather Huszti, a CHOC pediatric psychologist. Kids need moments when they can use their imagination, daydream and even goof off a little bit.
