Update: Bair Hugger MDL Court Orders 2 New Bellwether Trials

November 2, 2017 – The federal court overseeing MDL No. 2666 in Minnesota has ordered 2 knee replacement infection lawsuits to be prepared for bellwether trials, which are scheduled to begin in Sept. 2018. Case discovery for the complaints started on Sept. 26, and is expected to be completed by Dec. 8, according to an Order issued by the court on Thursday. Initial expert reports and disclosures are expected to be exchanged before the Thanksgiving break, with all rebuttals completed by December 15.

What is the Bair Hugger?

The Bair Hugger system uses forced, warm air to prevent and treat hypothermia in surgical patients. The device, which was created by Dr. Scott Augustine and approved by the U.S. Food & Drug Administration (FDA) in 1998, consists of a warming unit and disposable blanket that distributes warm air across the patient before, during and/or after surgery. Studies have shown that keeping a patient warm during surgery helps regulate their body temperature and prevents hypothermia, which results in less bleeding and faster recovery time.

What’s the Problem?

Even though he invented the device, Dr. Augustine now wants hospitals to stop using the Bair Hugger because it poses a danger to patients, according to The New York Times.

Specifically, Augustine asserts that his invention is a danger to patients receiving implant devices like artificial heart valves and joints because the forced air can spread bacteria associated with hospital-acquired infections. Heat generated by the Bair Hugger can redirect circulation in rooms where joint implant surgeries are performed, which can change air flow and bring airborne contaminants into contact with patients, according to Augustine.

“I am very proud of the old technology,” he said. “But I am also proud to spread the word that there is a problem.”

Manufacturer Accused of Hiding Problems with Bair Hugger

Augustine has also accused the company that sells the Bair Hugger, Arizant Healthcare Inc., of covering up problems with the device.

“The question for you to answer is the following; is Bair Hugger going to be replaced quickly and catastrophically by a mandatory recall, or do you survive a voluntary recall and live to fight another day?” Augustine wrote.

Arizant has filed a lawsuit against the inventor’s new company, Augustine Biomedical and Design, alleging that it distributed information that falsely disparages the Bair Hugger. Arizant was acquired by 3M for $810 million in Fall 2010.

Forced-Air Warming Studies

  • October 2009 – Study titled “Forced-Air Warming: A Source of Contamination in the Operating Room?” finds that forced-air-warming (FAW) devices like the Bair Hugger have the potential to generate and mobilize airborne contamination in the operating room. The authors recommended that manufacturers should redesign their products to ensure compliance with mandates for internal decontamination, and warned clinicians that FAW blowers emit more than just hot air.
  • November 2010 – Study published in the American Journal of Infection Control concludes that forced-air warming filters are inadequate to prevent airborne contamination emissions or protect the internal air path from microbial contamination buildup.
  • May 2011Journal Bone and Joint Surgery study compares the effects of forced-air and conductive fabric on operating theatre ventilation during simulated hip replacement and lumbar spinal procedures. The authors found a significant increase in deep joint infections with FAW devices and recommended air-free warming for orthopedic procedures.
  • March 2012 – Study in Anesthesia finds that forced-air warming generates convection current activity around the surgical site. The authors believe these currents may disrupt ventilation airflows intended to clear airborne contaminants from the surgical site.
  • August 2013 –  Article published in Anesthesia and Analgesia determined that warming devices like the Bair Hugger could present a potential risk for infection in prolonged vascular and hip surgery. The authors stated that forced-air warming “was found to establish convection currents that mobilized resident air from non-sterile areas (under the anesthesia drape) upward and into the surgical site.”

Bair Hugger Infections

Treatment to control and repair Bair Hugger infections may include:

  • Hospitalization
  • Surgery
  • Insertion of antibiotic spacers into affected joint(s)
  • IV antibiotic / physical therapy
  • Revision / removal of implant
  • Amputation 
  • Permanent Disability

3M Sued Over Bair Hugger Injuries

In 2013, a civil lawsuit was filed in the U.S. District Court, Southern District of Texas, on behalf of a 70-year-old man who allegedly developed a serious deep-joint infection following a surgery in which a Bair Hugger forced air warming blanket was used. Following the March 2011 procedure, the plaintiff required 15 additional surgeries, including one to remove his artificial hip due to the infection, according to the lawsuit.

The complaint alleges that the Bair Hugger pulled in contaminated air from under the surgical table, which then re-circulated into the hip replacement device that was being implanted. Defendants named in the complaint included 3M, Arizant, and a sales representative who works for 3M and Arizant. The lawsuit is: Case No. 4:13-cv-01164.

Another lawsuit currently pending in the U.S. District Court, District of Kansas, alleges that the Bair Hugger system caused a patient’s MRSA infection following knee replacement surgery. According to the complaint, the warming blanket allowed hot air to accumulate under the surgical drape and escape below the surgical table. The air allegedly created warm, rising airflow currents that transported bacteria from the floor into the surgical site. As a result of his MRSA infection, the plaintiff had to have his leg amputated. The lawsuit is: Case No. Case 2:14-cv-02044.

Heater-Cooler Infections

The Bair Hugger is not the only patient warming device to be linked to severe injuries. In October 2015, the FDA issued a warning about life-threatening Nontuberculous Mycobacteria (NTM) infections associated with heater-cooler systems used during open-heart surgery and other medical procedures. At least 6 patient deaths and dozens of microbial infections have been associated with the devices, according to CNN.
