Thermometers and rectal perforations in the neonate

Abstract

Three neonates with rectal perforations, probably caused by the use of the rectal thermometer, are reported. The dangers of this condition and the difficulty of diagnosis even at laparotomy are emphasised. It is suggested that since the axillary temperature in the neonate is an adequate reflection of the core temperature the routine use of the rectal thermometer, except in exceptional circumstances, should cease.
