Rectal thermometry

Rectal thermometry is a method of measuring body temperature by inserting a thermometer into the rectum via the anus. This is generally considered the most accurate means of temperature taking, but some may consider it to be an invasive or embarrassing procedure. Therefore, it is not used routinely in practice unless specifically needed.

Procedure

The procedure for rectal thermometry involves the use of a thermometer specifically designed for this purpose. The thermometer is usually digital, and has a flexible tip for comfort. It is inserted into the anus and left in place for a certain amount of time, usually a few minutes, until a reading can be taken.

Accuracy

Rectal thermometry is considered to be one of the most accurate ways to measure body temperature. The rectum is a closed cavity, and therefore not subject to the cooling effects of air and evaporation. This means that it can give a good indication of the body's core temperature.

Considerations

There are some considerations to take into account when using rectal thermometry. It is an invasive procedure, and some people may find it uncomfortable or embarrassing. It is also not recommended for people who have had rectal surgery or have other medical conditions affecting the rectum.

Alternatives

There are several alternatives to rectal thermometry. These include oral thermometry, where the thermometer is placed under the tongue, and axillary thermometry, where it is placed in the armpit. There are also tympanic thermometers, which take a reading from the ear, and temporal artery thermometers, which take a reading from the forehead.
