What should the rectal temperature be maintained at during hypothermia therapy?

During hypothermia therapy, the patient's rectal temperature should generally be maintained between 37.3°C and 37.6°C. However, due to individual differences in patients' physical conditions and environmental factors, rectal temperature may vary slightly, so clinical judgment should be based on each patient's specific circumstances.

Hypothermia therapy typically uses ultra-low temperature devices applied to affected areas to protect brain cells, reduce cerebral metabolic demand, and improve brain metabolism. The patient's body temperature can reflect the effectiveness of the therapy; under normal conditions, the target temperature is around 37.3°C. Since the rectal site is close to major blood vessels, rectal temperature is usually slightly higher than axillary temperature. Individual body temperatures vary, and factors such as a warm environment or heavy bedding may elevate rectal temperature to around 37.6°C. As long as the temperature does not exceed 38°C and the patient shows no abnormal symptoms, this is generally considered within the normal range.

During hypothermia therapy, the patient's body temperature should be closely monitored, along with other vital signs. Subsequent treatment strategies should be determined according to the patient's overall clinical condition.
