Do you know when your child is running a fever? What is the best way to take a child’s temperature to check for fever? Not sure how high the fever has to be before calling the pediatrician? As cold and flu season gets underway, now is a good time to review some thermometer basics.
A fever occurs when our bodies raise our temperature above the normal level (around 98.6 F or 37 C) to fight infection. The Mayo Clinic reminds us that not all fevers are bad and that they work to help fight infection. If your child is older than a year, sleeping through the night, playing as usual, and drinking fluids, you may decide to let the fever run its course.
If you do decide to treat a child who is uncomfortable with a fever, Mayo Clinic advises that you use acetaminophen if the child is younger than six months. Ibuprofen or acetaminophen is okay to give to children six months and up.
Remember to read packaging for proper dosing and never give aspirin to anyone, 18 years and younger, to treat for a fever.
The Mayo Clinic offers several guidelines about when to call the doctor. If your child is older than three months, call the doctor if: the temperature is 102 F/38 C and acts irritable or lethargic, or if the fever is 102 F or higher and won't respond to over-the-counter fever reducers, or lasts longer than a day. If your child is younger than three months, call the doctor if the rectal temperature registers 100.4 F/38 C or higher.
The Family Doctor website shares advice on taking a child’s temperature accurately. If you take the temperature rectally, you will get the most accurate reading. However, if a child is older than three months, a digital oral thermometer can be used.
While many of us now own digital thermometers, it is good to remember that older thermometers containing poisonous mercury are not recommended.
Before you use the thermometer, clean it using soap and lukewarm water, and rinse with cool water. After use, wash in cool, soapy water or wipe clean with rubbing alcohol.
If you take the temperature orally, remember to wait 20 minutes if your child has just had something warm or cold to eat or drink.
