How They Work • A probe containing a thermocouple or thermistor is placed in the on the skin. • The probe is connected to a small amplifier box which displays the temperature. • In sedation patients it is usually taped to the abdomen.
WHAT DOES IT TELL US? Patients temperature is important as hypothermia can be a cause of delayed recovery from anesthesia/sedation. Body temperature can be maintained in sedated patients with blankets. Water recirculating blankets and warm air re-circulators ( bair hugger) are used in operating theatres. Because there is a decreased risk of burns with warm air re-circulators ( bair hugger), these are the most common means of maintaining normothermia in the OR. These however is very costly and not necessary for a sedation practice.
The Bair Hugger Blanket is placed under a normal blanket or Surgical drapes
Normal Temperature Values • Normothermia is defined as core temperature of 36° Celsius or 96.8°F. • In the general anesthetic world core temperature can fall as much as 1.6° Celsius within the first hour following induction. • In the sedated patient the core temperature can also fall but not the same degree as with general anesthesia. • As stated earlier in sedation we monitor skin temperature as opposed core temperature and therefore we look at changes from baseline readingsto assess normothermia.
