Thus, it is frequently used sparingly and primarily on babies, children or adults for whom taking an oral temperature would risk injury (e.g. an unconscious patient, a post-oral surgery patient, or a person suffering a seizure) or be inaccurate (due to newly ingested liquids or breathing through the mouth).
The precise history of rectal thermometry is largely unknown, but medical thermometers have long been made in a tube shape that fits into the anus. Medical literature shows the practice dating back to the 18th century, and it is probable that thermometry was believed to be a safer alternative to oral temperature-taking, because of the use of mercury and other toxic chemicals in early thermometers. As technology improves in the 21st-century thermometry is becoming less and less pervasive, but it’s still the preferred way of taking the temperature of infants and pets.

Rectal thermometry is widely used in veterinary medicine and pediatrics as well as by adults at home who want the most accurate possible temperature reading and overlook the invasive nature linked to the painless procedure. It is accomplished by inserting the tip of a thermometer, usually lubricated with either petroleum jelly (Vaseline) or more recently water-based lubricants such as K-Y Jelly to eliminate friction and aid in insertion passed the tightly retentive sphincter of the anus, about 1–2 inches into the anus.

The thermometer tip should then be left in position until a reading can be derived approximately 3 minutes to get mercury thermometers and one minute for newer types that were electronic. It’s important to bear in mind that the typical human core temperature range that is measured with a rectal thermometer spans from 98.6 to 100.4 degrees Fahrenheit (37.0 to 38.0 degrees Celsius).
