RECTAL THERMOMETER-INDUCED PNEUMOPERITONEUM IN THE NEWBORN

Abstract

Two cases of pneumoperitoneum of the newborn caused by perforation of the rectum by a rectal thermometer are presented. The infants presented with symptoms of respiratory distress and cyanosis associated with vomiting and abdominal distention. The literature on the subject is reviewed. Only seven such cases have been reported to date, and the mortality approximates 70%. The single most important factor affecting prognosis appears to be the state of maturity at the time of reparative surgery. Of five mature infants operated on within 24 hours of symptoms, four have survived and have done well. We strongly advocate caution in the use of rectal thermometers, and we would suggest that axillary temperatures or flexible rectal probes be used whenever possible.
