how to use a rectal thermometer

time2011/10/14

  • Look for a rectal thermometer that has a flexible tip and a wide handle that doesn't let you insert it more than an inch. (If you were to accidentally insert the thermometer too far — if your baby gets very squirmy, for example — you could perforate your baby's rectum.)
  • To prepare the thermometer, clean the end with rubbing alcohol or a little soap and warm water. Rinse with cool water. Then coat the end with a little petroleum jelly for easier insertion or use a disposable sleeve made for that purpose.
  • Hold your baby on your lap, tummy down and bottom up, letting his legs dangle over the side of your thigh. Or place him on his back, either on the bed or on a changing table. Your baby may be more comfortable in the tummy-up position, since he's used to lying that way for diaper changes. Besides, you'll be better able to distract him if he can see your face.
  • Press the thermometer button to turn it on. With your other hand, spread your baby's buttocks apart. Gently insert the bulb about half an inch to an inch (1.3 to 2.5 centimeters) into his rectum, or until the tip of the thermometer disappears.
  • Keep a firm grip on his buttocks by cupping them with the palm and fingers of the hand that's holding the thermometer. Don't let go of the thermometer, or it may not stay in place if your baby starts wriggling.
  • When the thermometer beeps, remove it and read your baby's temperature. Be aware that inserting anything into your baby's rectum can stimulate his bowels, so don't be surprised if he poops when you take the thermometer out. Clean the thermometer with soapy water or rubbing alcohol, then rinse and dry before storing.
