Rectal thermometry

Rectal Thermometry

Rectal thermometry (pronounced: rek-tuhl ther-mom-i-tree) is a method of measuring body temperature by inserting a medical thermometer into the rectum via the anus. This is generally considered the most accurate means of temperature-taking, but not the most comfortable or convenient.

Etymology

The term "rectal thermometry" is derived from the Latin word "rectum", which means straight, and the Greek word "thermometry", which is a combination of "thermo" (heat) and "metry" (measure).

Procedure

The procedure for rectal thermometry involves the use of a digital thermometer or a mercury thermometer. The thermometer is gently inserted into the rectum, which allows it to measure the body's core temperature. This method is often used for infants, young children, or adults who are unable to hold a thermometer in their mouth.

Related Terms

Fever: An elevated body temperature, often a sign of illness.
Hypothermia: A dangerously low body temperature.
Hyperthermia: A dangerously high body temperature.
Oral thermometry: A method of measuring body temperature by placing a thermometer under the tongue.
Axillary thermometry: A method of measuring body temperature by placing a thermometer in the armpit.
Tympanic thermometry: A method of measuring body temperature by placing a thermometer in the ear canal.

Risks

While rectal thermometry is generally safe, there are some risks associated with the procedure. These include the potential for rectal injury if the thermometer is inserted too forcefully or too far. There is also a small risk of spreading bacteria from the rectum to other parts of the body.
