The 3M Bair Hugger forced-air warming system

The U.S. Food and Drug Administration recently issued a letter reminding healthcare providers that it continues to recommend patients be warmed during surgery when clinically warranted.

The FDA specifically mentioned that its recommendation includes the continued use of forced-air warming devices. The 3M™ Bair Hugger™ warming system is the world’s leading forced-air warming product.

The FDA said it recently became aware that some providers and patients are foregoing the use of forced-air warming because of concerns about a possible increased risk of surgical site infections. Those concerns have been driven by a 3M competitor and a group of plaintiffs’ attorneys, who are promoting a theory that forced-air warming devices such as the Bair Hugger system lead to an increased risk of surgical site infections.

The FDA, which regulates medical devices, said it has thoroughly reviewed available data and “has been unable to identify a consistently reported association between the use of forced air thermal regulating systems and surgical site infection.”

Researchers add to wealth of evidence supporting 3M™ Bair Hugger™ patient safety

Posted by:

The 3M™ Bair Hugger™ patient warming system has warmed more than 200 million patients since its launch in 1987, and that number grows by nearly 50,000 patients each day. One reason for the Bair Hugger system’s success is an impressive history of safety and effectiveness.

So when a competitor makes outlandish claims that fly in the face of 28 years of clinical use and a wealth of scientific research (over 170 studies and more than 60 randomized controlled clinical trials document the clinical benefits, efficacy and safety of forced-air warming), we will rely on science to set the record straight.

Researchers John P. Abraham, Ph.D., Professor of Thermal Sciences at the University of St. Thomas, and Jennifer A. Wagner, Ph.D., Prism Environmental Health and Safety Solutions, recently released the results of a study, which found that the Bair Hugger system did not disrupt clean operating room airflow and did not move air from the the floor to the surgical site.  The Bair Hugger Warming System is a safe, effective method to warm your surgical patients. Take a few minutes to review the study overview below. The videos also do an excellent job of depicting the results, and can be viewed here.

Operation Room Air Flow Study with 3M™ Bair Hugger™ Warming System in Simulated Hip Replacement Surgery

John P. Abraham, Ph. D., University of St. Thomas and Jennifer A. Wagner, Ph. D., Prism Environmental Health and Safety Solutions

The Bair Hugger Warming System provides a safe and effective way to maintain normal body temperature during surgery.  When used properly the Bair Hugger Warming System lowers the risk of hypothermia and improves patient recovery and surgery outcomes (i.e. reduces risk of surgical site infection, blood loss and transfusion requirement, prolonged recovery, and fatal heart attack).  A scientific research project was undertaken to assess whether the Bair Hugger System disturbed the clean-air flow in an operating room in the vicinity of a sterile surgical site.  The investigation showed that the Bair Hugger Warming System did not disrupt the normal airflow patterns of an operating room, and did not move air from the floor to the surgical site in a simulated hip replacement procedure.

The investigation had three separate components. One part of the investigation incorporated advanced mathematical calculations based upon the fundamental laws of physics to track the paths of airflow in the operating room. The calculations demonstrated that the air from the Bair Hugger System avoided the surgical site. The air flow that emerged from the Bair Hugger System traveled away from the surgical table and migrated toward the room exhaust vents along with the air beneath the operating table – not toward the surgical site.

A second part of the investigation involved experiments performed in an operating room with flow visualization studies that purposely injected visible fog into multiple locations in the room: 1) behind the anesthesia screen where the Bair Hugger air would exit near the patient’s head; 2) underneath the surgical table; and 3) next to the surgical table, near the surgical team, and near the surgical site. This investigation found that downward clean moving air from ceiling supply ducts in an operating room inhibited air from other sources from intruding into the surgical region. The downward flow of clean air worked irrespective of whether the Bair Hugger Warming System was used or not.

The third part of the investigation included a review of the scientific literature. The best scientific work did not show any causal link between the use of a Bair Hugger Warming System and surgical site infections. Even contrary research, which was largely funded by a competitive company, failed to show any causal link. More than 170 clinical studies have utilized the Bair Hugger system, and studies have demonstrated forced-air warming’s clinical effectiveness. Studies have demonstrated perioperative temperature management with forced-air warming actually reduces the risk of surgical site infections, surgical bleeding3-5 and risk of heart attack6.

The findings of the three components of this investigation mutually reinforce one another. All of these studies showed that the Bair Hugger Warming System is safe when used according to manufacturer directions, providing an effective way to maintain patient temperature.

Ask for evidence when determining forced-air patient warming fact from fiction

Posted by:

Since 1987, the 3M™ Bair Hugger™ patient warming system has maintained a commitment to excellence by focusing on three guiding principles:

  1. Educating clinicians on the benefits of maintaining normothermia and emerging trends/science in the field of temperature management.
  2. Improving our products to continuously reflect customer needs and remain an industry leader in technology advancement.
  3. Supporting key research to advance the science of normothermia maintenance.

These principles are as relevant—if not more so—in today’s healthcare environment, where patient outcomes and clinical value lead the decision-making process. Medical devices are no longer products you sell to doctors or nurses based on “features” alone; they are tools that must contribute to better outcomes while providing an economic benefit worthy of investment.

The patient warming industry is a microcosm of the larger healthcare environment. Competition is growing and new technologies are attempting to gain a foothold in a crowded market. It’s virtually impossible for clinicians to distinguish between fact and fiction as they are bombarded with clever sales tactics and products claiming equal performance at lower cost.

Clinical Evidence is Key

To truly separate clinically supported warming technologies from “me too” imitators, clinicians should demand the clinical evidence supporting a manufacturer’s claims of performance, safety and overall value.

3M’s commitment to the science of temperature management has never been more evident. Recently, the company announced the publication of a robust research compendium highlighting the safety and effectiveness of the Bair Hugger patient warming system. The compilation of over 200 study summaries includes more than 60 randomized controlled trials and covers a wide range of surgeries – including hip, knee, cardiac and abdominal procedures – and reinforces the sheer volume of extensive research supporting the clinical use of the Bair Hugger system.

The compendium features summaries of publications in which the Bair Hugger system was either the subject of (or used during) a clinical research study or investigation. Also included are review articles, case studies and letters to the editor, which introduce relevant information or real-world user experience with the Bair Hugger system.

The compendium was assembled utilizing multiple search engines and five databases, including Medline, Embase, Biosis, Elsevier Biobase and Chemical Abstracts. Many of the included studies measure the performance of the Bair Hugger system against competing technologies, ranging from convection warming to resistive polymer technologies.
