Fever 101 - A guide to kid's fevers

Fever in children can be a scary thing for parents, often causing them to wonder if a trip to the emergency room is necessary. Le Bonheur Pediatrician Ruth Patton MD, of Pediatric Consultants, shares the advice she often gives parents when their child feels feverish.

"Don’t panic,” says Dr. Patton. “Know that fever is the body’s natural reaction to infection.

Dr. Patton offers three important questions to ask yourself when your child has a high temperature:

1. Is your child's breathing labored?
2. Is your child drinking less or experiencing decreased urine output?
3. Is your child crying inconsolably?

If you answer yes to any of these questions, it's best to call your pediatrician's office, no matter your child's degree of fever.

Dr. Patton stresses that if you have an infant younger than 2 months with a rectal temperature of 100.4 degrees Fahrenheit or higher, you need to call your pediatrician immediately. Fever in newborns does require an exam, as newborns have immature immunity and are more susceptible to serious illness.

Even if your child does not show signs of serious illness, a fever can make him or her uncomfortable. To make your child as comfortable as possible, you can provide temporary relief by administering a dosage of acetaminophen or ibuprofen if he or she is 6 months or older. Most children with a temperature lower than 101 degrees Fahrenheit may not need medication, but if you notice that your child is uncomfortable, it won't hurt to give them an over-the-counter medicine. You should also keep your child dressed in light clothing, keep the house at a comfortable temperature, offer plenty of fluids and make sure they rest.

Knowing your child's normal behavior and the symptoms that are accompanying the fever is the most important information for you to consider. As long as you don't notice any of the three red flags, a trip to the doctor's office probably isn't necessary. Just remember to monitor your child closely. If the fever has not reduced after 24 hours on medication, call your child's pediatrician.
