Bair Hugger Patient Warming  Pediatric Donation

Excitement builds ahead of ANESTHESIOLOGY® 2016. Get a “sneak peek” at what we’ll be sharing. 

ANESTHESIOLOGY® 2016 is just days away, and we have some exciting announcements to share.

Since 1987, one of health care’s most iconic brands, the 3M™ Bair Hugger™ system, has provided innovative patient warming products with a singular purpose—the maintenance of perioperative normothermia in surgical patients.

Today 3M, a world leader in infection prevention, announced the launch of a revamped Bair Hugger brand. The 3M™ Bair Hugger™ Normothermia System incorporates a new visual identity with a more comprehensive product portfolio designed to better reflect its singular mission. The brand will be unveiled at the ANESTHESIOLOGY® 2016 conference in Chicago beginning Saturday, Oct. 22.

The Bair Hugger system, acquired by 3M in 2010 along with the Bair Paws™ patient adjustable warming system and the SpotOn™ temperature monitoring system, represents a legacy of industry first warming solutions and has safely, effectively warmed more than 200 million patients across the globe. The new Bair Hugger Normothermia System brand will incorporate all three product lines into one, cohesive normothermia solution to help clinicians measure and maintain body temperature throughout a patient’s surgical journey.

Our refreshed brand goes much deeper than just a new logo and brand name. It combines our customer-centric mindset with our deep industry expertise and a commitment to innovation, science and patient outcomes. The products in the 3M Bair Hugger Normothermia System are the same reliable solutions our customers use more than 50,000 times each day, now presented under a single brand name focused on maintaining normothermia, safeguarding outcomes and nurturing the patient experience.

Bair Hugger Multi-Position Blanket Supine Shoulder

New product launch 3M™ Bair Hugger™ Multi-position upper body warming blanket

The 3M™ Bair Hugger™ Multi-position upper body warming blanket, which will be unveiled at this weekend’s ANESTHESIOLOGY® 2016 conference in Chicago, is engineered to address these warming dilemmas with its ability to bend and conform to the patient’s body while providing uniform temperatures to the patient. The blanket is designed to maximize patient coverage with one easy-to-use warming solution. Its unique bendability enables clinicians to adapt the blanket to multiple surgical positions and procedures, to help maintain normothermia.

The multi-position upper body blanket highlights a new air channel design and lower profile, but still includes all the features that customer expect from a Bair Hugger upper body blanket, including integrated tie strips, adhesive strip, attached clear head drape and two resealable hose ports.

Charitable Contribution

And what better way to celebrate these two important launches than by giving back through a charitable contribution?

3M is pleased to announce that we’ll be making a $25,000 donation to the Ronald McDonald House Charities of the Upper Midwest. In addition, 3M is encouraging ANESTHESIOLOGY® 2016 attendees to visit the 3M exhibit (booth #2423) during the show to help us give even more.

Each visitor to the booth will be provided with a small vinyl cling and encouraged to apply it onto a large tracking thermometer. If the thermometer fills with clings by the end of the show, we’ll also be including 250 plush, purple bears along with our cash donation.

We look forward to seeing you at ANESTHESIOLOGY® 2016!

The Science Behind Patient Warming and the Benefits of Normothermia

Perioperative Patient Warming

Read the study summary – Target Normothermia: A Global Focus on Inadvertent Hypothermia


Under normal circumstances, the body controls its temperature within a very tight tolerance, with the core being 2-4˚C warmer than the periphery. This temperature gradient between the core and the periphery is caused by normal thermoregulatory vasoconstriction. Anesthesia induction results in vasodilation, which allows the warmer blood to flow freely from the core and mix with the blood from the cooler periphery, lowering the core body temperature. Research has shown that in the first 60 minutes under anesthesia unwarmed surgical patients can lose up to 1.6˚C1,a phenomenon known as redistribution temperature drop (RTD).

Unintended perioperative hypothermia

Unintended hypothermia remains a common—but easily preventable—complication of surgery.2 It is estimated that unintended hypothermia, defined as a core body temperature of less than 36.0°C (96.8°F), occurs in more than 50% of all US surgical patients, even those undergoing short procedures (one to one-and-a-half hours).3

Numerous studies have demonstrated that even mild perioperative hypothermia can result in significant complications. Unfortunately, temperature management of the surgical patient remains a secondary consideration in many perioperative settings rather than an essential standard of care.

Benefits of normothermia

The benefits of maintaining normothermia have been thoroughly researched and documented in independent peer-reviewed articles. A number of these studies are randomized controlled studies that document the importance of preventing hypothermia.

In a landmark meta-analysis performed by Chris Brown Mahoney, she captured the essence of earlier research which identified dramatic decreases in the complication rates and the related patient care costs that can be avoided by keeping patients normothermic. Normothermia is a process improvement that touches the entire patient care algorithm. This meta-analysis of 20 studies covering 1,575 patients identified reductions in patient costs in several different areas when normothermia is maintained such as:5

  • Reduction in the use of blood products
  • Shortened length of hospital stay
  • Decreased ICU time
  • Reduced rate of wound infection
  • Decreased likelihood of myocardial infarction
  • Lower mortality rates

There is also a significant financial benefit of reducing hypothermia rates in surgical patients. Maintaining normothermia can result in savings of $2,500 to $7,000 per patient by eliminating the costs of hypothermia-related complications, including surgical site infections.5
