Warming solutions for Clinicians

What clinicians need to know

Studies show that 50-90% of patients undergoing anesthesia will become hypothermic at some point during their surgery due to a phenomenon called “redistribution temperature drop.” Patients who become hypothermic at any point during their surgery are at greater risk for negative outcomes such as surgical site infections, adverse cardiac events and excessive blood loss. 

Guidelines¹,² from various associations around the world recommend actively warming and taking temperatures of patients who are undergoing surgeries lasting longer than 30 minutes. These same guidelines also recommend pre-warming patients to reduce the effects of redistribution temperature drop. 

The 3M™ Bair Hugger™ Normothermia System offers a wide range of patient warming solutions to help reduce patient hypothermia. Our 3M™ Bair Hugger™ Warming Gowns and Blankets will actively warm your patients before, during and after surgery. 

The 3M™ Ranger™ Blood and Fluid Warmer System will help maintain your patients’ normothermia while they are being actively warmed. 

And our non-invasive 3M™ Bair Hugger™ Temperature Monitoring System will help you monitor your patient’s temperature throughout their surgical journey.

Products for maintaining normothermia

  • We believe degrees matter and everybody deserves a hug. The 3M™ Bair Hugger™ Normothermia System provides a wide range of patient warming products that play a critical role in maintaining normothermia, helping safeguard patients and improving outcomes. From blankets to gowns to temperature monitoring, we’ve got you covered.

  • Warming fluids will not maintain normothermia on their own, but are considered an important adjunct therapy to forced-air warming. It is important to have a mechanism that reduces the risk of delivering air to the patient. The 3M™ Ranger™ Fluid Warming System offers a variety of sets that meet your fluid warming needs.

  • We understand that the success of a patient’s surgery can depend on the equipment that is used during the surgical journey. Knowing how to clean and maintain your patient warming equipment is important, so we have developed a page dedicated to answering questions pertaining to equipment servicing.
