Discharge Instructions: Taking a Rectal Temperature (Pediatric)

You take a rectal temperature by placing a thermometer in your baby’s bottom. This method provides the most accurate reading. But do this only when instructed by your baby’s doctor. Use the steps on this sheet as a guide.

Get the Thermometer Ready

• Be sure to use a thermometer that is specifically designed for rectal use.

• Remove the cover from the thermometer.

• Wash the thermometer with warm soapy water; then rinse with clear water.

• Wipe the thermometer dry or let it air dry.

• Smear a bit of petroleum jelly or water-based lubricant on the tip.

Find a Comfortable Position for Holding Your Baby

• Put your baby on his or her back on a firm surface.

• Hold the baby’s ankles and lift both legs, as if changing a diaper.

Or

• Place your baby face down across your lap.

• Use one hand to part the baby’s buttocks.

Take the Temperature

• Follow the specific directions for using your digital thermometer.

• Gently slip the tip of the thermometer into the rectum (the opening where bowel movements leave baby’s body), no farther than ¼ to ½ inch. Never insert the tip more than ½ inch.

• Hold the thermometer in place until it beeps.

• Slide the thermometer out. Read the temperature on the digital display. Normal rectal temperature is about 97.6°F (36.4 °C) to 100.2°F (37.9°C).

• Before putting the thermometer away, clean it with soap and warm water.
