  • Title: [Use of bladder thermistor catheters in an intensive care unit. Comparative study of core temperature measurements with bladder thermometers and rectal thermometers in an intensive care unit].

    Journal: Ugeskr Laeger; 1993 Jul 26; 155(30):2347-9. PubMed ID: 8346579.
    Abstract:
    Bladder temperature measured by a thermistor tipped urinary catheter was compared to rectal temperature in 14 ICU patients. During a period of five days 2 x 232 measurements were recorded, and good correlation was found between rectal and bladder temperatures (R = 0.97). There did not seem to be any drift in the bladder thermistor. Measurement was accurate during periods of oliguria. We find that bladder temperature measurement is reliable, safe, convenient and accurate for routine use in the ICU.
