Electronic rectal thermometry is performed routinely in most medical centers. While electronic thermometry has been validated at the oral site, rectal measurement has not. We performed a controlled study on 84 children comparing mercury-in-glass and electronic thermometry at the rectal site. No significant difference occurred in temperatures between the two methods. We conclude that the electronic thermometer is a valid instrument to measure rectal temperature.
