Monitoring temperature in children under general anesthesia; nasopharynx versus carotid artery surface

Background: continuous body temperature monitoring during anesthesia in children is very important.  Hypothermia in children results in increased morbidity and mortality. Measurement point of the core body temperature are not easily accessible. the purpose of this study was to measure skin temper...
