We are on a mission to reduce the risk of perioperative hypothermia complications

Unintended hypothermia is easily preventable. Studies show that warming patients by maintaining a core temperature of 36ºC or higher, helps to improve outcomes by reducing the frequency of complications often associated with inadvertent hypothermia. The consequences of hypothermia include higher mortality rates, longer hospital stays and an increased rate of wound infection.1-5 3M is dedicated to providing patient warming solutions that help to enhance patient recovery.

  • The Science of Warming: The Physiology and Physics of Forced-air Warming

    The Science of Warming: The Physiology and Physics of Forced-air Warming

    • Prof. Dr. Anselm Bräuer is a Consultant Anaesthetist and leading normothermia expert who has published more than 70 articles about hypothermia, over 20 book chapters, and is co-author of the German, Austrian and Swiss Guidelines for the prevention of perioperative hypothermia.
    • In two short videos, Prof. Bräuer explains how forced-air warmers change the heat balance of the patient in the operating room and describes how actively warming the patient before induction of anaesthesia, can minimise redistribution temperature drop.
    • You will also learn about the physics between the warming unit and the blanket heat exchange system, and between the warming blanket and patient.


  • Prewarming: Reducing the risk of complications in surgical patient

    Prewarming: Reducing the risk of complications in surgical patients

    • Clinicians around the world have been implementing the optimal warming protocol using the 3M Bair Hugger Normothermia System with highly positive results. In this short online module, normothermia experts share their experiences and knowledge.
    • Prof. Alfonsi, co-author of the 2018 expert recommendations of the French Society of Anaesthesia (SFAR), shares insights from his published study highlighting effect that interruptions in active warming can have on perioperative hypothermia.
    • Prof. Bräuer explains the importance of pre-warming in the prevention of perioperative hypothermia in surgical patients.
    • And finally, Dr. Grote shares his real world practical experience of significantly reducing hypothermia rates by implementing a pre-warming protocol with the Bair Hugger Normothermia System.


Now that you are ready to take action to improve patient outcomes, we are here to support you with tools and resources to make positive changes in practice. Download a recent budget impact analysis on pre-warming below, or visit our main page to explore other resources available.
