With flu fears flying around and cold season upon us, everyone is watching for symptoms like fever, especially in children. These days, there are dozens of different kinds of thermometers on store shelves, so how do you know which one is the best fit for your family? For Canton mom Therese Delashmutt, it was more a process of elimination. Her toddler Gabe doesn’t care much for the traditional thermometers. Delashmutt explains, “There was no way he’d keep a thermometer under his tongue, or his arm for that matter.” So each time Gabe got sick, Therese tried a different kind of thermometer. And she had many, many options to try, with so many on the market.
The National Institutes of Health is currently conducting a study comparing the accuracy of oral, ear and forehead, or temporal, thermometers. The American Academy of Pediatrics no longer recommends the old-fashioned mercury models for environmental reasons. But, according to Atlanta pediatrician and AAP Spokesperson Dr. Jennifer Shu, “When it comes to digital devices, choosing one has more to do with the age of the child than the type of thermometers.”
So what works? Dr. Shu explains, “For babies under six months, the most accurate way to do it is through a rectal thermometer. A lot of parents don’t want to do that on a regular basis if the baby might not be that sick, so it’s perfectly fine to do an underarm thermometer.” However, Dr. Shu suggests you double-check an underarm reading over 99 with a rectal reading before heading off to the doctor.
If the child is older than six months you can try an ear thermometer or the temporal type. How does that work? Dr. Shu says it’s simple. “Swipe it across the child’s forehead and behind the ear and that tends to be very reliable. It’s very easy because the child doesn’t have to sit still for very long and it’s incredibly fast and painless.” That’s what worked for Therese. When he got sick recently with a stomach bug, Gabe not only sat still for the temporal reading, but according to Therese, “he even helped hold his hair up for us”.
There are other options, too. Some are strips that sit on the forehead or pacifier type models. There are even some that light up red, yellow or green for easy readings in the dark. The AAP says don’t worry if one type is a degree or two off from another method. The important part is to tell the pediatrician how the measurement was taken, with what device. Dr. Shu suggests, “Try not to do any adding or subtracting at home and we’ll just take the whole picture into account.”
But do be careful of things that will impact the information you get. For example, if your child just ate something cold or hot, the number will reflect that. Also allow for outdoor interference, especially if you use an ear thermometer right away. “Wait for about 15 minutes and let the child’s temperature warm up to the regular body temperature and the room temperature, as well,” Dr. Shu recommends.
Also keep in mind that fever doesn’t say everything when your child is sick. Take into account their changes in mood, alertness and sleeping and eating habits when you decide if your child needs a doctor.
Therese is thrilled to have an easier time of taking her son’s temperature after being sick of the added frustration of the fight to find out if he had a fever in the past. “When your kid is sick, you’re running around cleaning up after them. One less thing to worry about is awesome.”
