Frequently Asked Questions (FAQs)

1. Are rectal thermometers still used?

Yes, rectal thermometers are still used, especially for taking the temperature of babies and toddlers up to 3 years of age. The American Academy of Pediatrics recommends using a rectal thermometer for accurate results in this age group.

2. What age is best for rectal thermometer?

Rectal thermometers are best for babies younger than 3 months old and kids 6 months to 3 years old. For babies 3 to 6 months old, you can also use a temporal artery or axillary method, but rectal temperature is still preferred.

3. Where do you put a rectal thermometer?

To take a rectal temperature, lay your baby or child on their back, lift their thighs, and insert a lubricated thermometer 1/2 to 1 inch into the rectum. Alternatively, you can place your child on their belly on a firm surface.

4. How accurate are rectal thermometers?

Rectal thermometers provide the most accurate temperature readings. Forehead thermometers are the next most accurate, followed by oral and ear thermometers. Armpit temperatures are the least accurate.

5. What are the disadvantages of rectal thermometer?

Some disadvantages of using a rectal thermometer include the risk of contamination with bacteria and feces, discomfort and embarrassment for the person being measured, and a slight lag in measuring the core temperature compared to other methods.

6. Do rectal temps hurt?

Rectal temperatures do not usually hurt if you use a thermometer designed for rectal use. Most thermometers have an alarm to indicate when the measurement is done, and they provide a digital readout of the temperature.

7. Can you use aquaphor as lube for rectal temp?

Yes, you can use a lubricating jelly such as Aquaphor or Vaseline to lubricate the silver bulb of the rectal thermometer.

8. How accurate is a rectal thermometer for a baby?

Rectal thermometers are accurate for taking a baby's temperature, as are forehead thermometers. After 6 months old, an ear thermometer can also be used. Armpit temperature is suitable for screening purposes if taken correctly.

9. How long do you leave a rectal thermometer in?

When taking a rectal temperature, insert the bulb end of the thermometer into the anal canal no more than 1 inch. Keep the thermometer in place until it beeps or for at least one minute.

10. Do you add 1 degree to rectal thermometer?

Rectal temperatures tend to be about ½ a degree higher than oral temperatures and 1 degree higher than underarm temperatures. A rectal temperature of 100.4-102 degrees Fahrenheit is considered mild fever, 102-103 degrees is moderate fever, and above 103 degrees is high fever.
