Original research date April 2010 Unreferenced date April 2010 Rectal thermometry is an umbrella term covering the practice, widely used in modern medicine and science, of taking a mammal s temperature by inserting a thermometer into the aforementioned mammal s rectum via the anus . This is generally regarded as the most accurate means of temperature taking, but some may consider it to be an invasive or demeaning procedure. Thus, it is often used sparingly and primarily on young 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 . History The precise history of rectal thermometry is largely unknown, but medical thermometer s have long been made in a tube shape that fits into the anus. Medical literature shows the practice dating back to at least the 18th century, and it is probable that rectal thermometry was thought to be a safer alternative to oral temperature taking, due to the use of mercury element mercury and other toxic chemicals in early thermometers. As thermometry related technology improves in the 21st century, rectal thermometry is becoming less and less pervasive, but it is still the preferred method for taking the temperature of infants and pets. Use and procedure 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 do not mind the discomfort associated with the procedure.
