What is Normothermia?

In the surgical environment, degrees matter. The maintenance of a normal core body temperature, normothermia, is a crucial component of patient safety. Core temperatures outside the normal range pose a risk in all patients undergoing surgery and have been associated with an increased risk of surgical complications, including surgical site infections.

  • Patient prewarming can help maintain normothermia


  • Prevent unintended hypothermia in surgery

    The difference between a positive patient outcome and a complicated recovery can be a matter of degrees. Unintended perioperative hypothermia is a frequent, yet preventable, complication of surgery. It can:

    • Increase the rate of wound infection (SSI)1
    • Extend recovery time2
    • Extend length of stay1
    • Increase mortality rates3

    However, hypothermia can be easily prevented when temperature is monitored and an active warming measure is instituted throughout the perioperative process - starting before the induction of anesthesia.

    The 3M™ Bair Hugger™ normothermia system provides a comprehensive solution that works seamlessly throughout the perioperative process to effectively and efficiently measure and manage patient temperature.
