“Wave” of Bair Hugger Litigation?

A news article published in Clinical Quality & Infection Control, a publication of Becker’s ASC Review, stated: “Recent studies published in medical journals questioning the safety of forced-air patient warming in orthopedic implant and other ultra-clean surgeries could mean a wave of new litigation.” The studies, said the writer, show that forced-air blowers contain internally generated airborne [...]

Infection Guidance: Air Turbulence in Operating Room Increases Risk of Orthopedic Infection

In its Guide to the Elimination of Orthopedic Surgical Site Infections, the Association of Professionals in Infection Control and Epidemiology (APIC) states, “If airflow is interrupted, rapid air turbulence can stir settled particles, enabling them to become airborne thus increasing the risk for wound contamination.” By applying recent research to APIC’s Guidance, StopSurgicalInfections.org found that [...]

New ECRI Guidance Expresses “Concern” About Forced-Air Warming in Implant Surgery

In the latest issue of Health Devices, ECRI Institute analyzed the safety of forced-air patient warming, concluding that thermal currents are “particularly worrisome” in implant surgery. Dr. Scott Augustine, inventor of both Bair Hugger and (air-free) HotDog patient warming and CEO of Augustine Temperature Management, comments. Minneapolis, MN (PRWeb), April 17, 2013 -  After reviewing multiple [...]

Video Evidence of the Vortex Caused by the Radiant Waste Heat from FAW Blankets

The video clip below is an excerpt from a nurse education course.  It shows the vortex-effect caused by the radiant waste heat from forced-air patient warming (FAW) blankets, similar to what was recently studied and published by orthopedic surgeons A.J. Legg and A.J.Hamer. The Legg and Hamer study, published in the Bone & Joint Journal in March 2013, [...]

Study: Contamination Increased 2000x With Bair Hugger Warming

Minneapolis, MN: March 14, 2013— The use of Bair Hugger forced-air warmers during surgery creates convection currents that capture particles below the surgical table, lifting them into the sterile surgical field, according to research recently published by orthopedic surgeons. The waste heat radiating through the surgical drape induced the formation of tornado-like vortexes of rapidly spinning [...]

The Paradox of Forced-Air Patient Warming

Studies show that forced-air warming (FAW) reduces soft-tissue surgical infections. How can FAW be linked to increased deep-joint infections? The paradox is easy to explain: BIOFILM.  A bacterium that lands on a prosthetic implant can secrete a coating of biofilm that protects it from both antibodies and antibiotics. Bacteria in soft-tissue cannot form effective biofilm coatings. [...]

Evidence of the risks of forced-air warming just keeps growing.

A study published online ahead of print in Anesthesia & Analgesia concludes that forced-air patient warming produces waste heat that disrupts operating room ventilation airflows over the surgical site, transporting non-sterile air to the area and hindering the ventilation system’s ability to clear potential airborne contaminants. “There are some in our industry that would like [...]

3M accuses Augustine of “instilling fear through misleading claims.” Really? Let’s look at the facts…

Four independent peer reviewed studies have been published showing that forced-air patient warming devices generate convection currents that disrupt the sterile field.  One such study (McGovern, JBJS-br, 2011) even showed a 74% decrease in deep-joint infection rates after discontinuing the use of forced-air patient warming. They switched to air-free HotDog patient warming (1250 patients, 2.5 [...]

Evidence Growing Against Safety of Forced-air Patient Warming

Yet another peer-reviewed study—the third in the past five months—has been published showing that forced-air patient warming generates convection current activity in the vicinity of the surgical site, which could lead to contamination of the sterile field. The study, published by Dr. Kiran Dasari in the March issue of Anaesthesia, is more evidence that a significant [...]

Another Study Shows the Risks of Using Forced-air Patient Warming

Researchers in the UK published a study in the February, 2012, issue of the Journal of Bone and Joint Surgery-Brexamining the effects of forced-air warming on operating room airflow and surgical site sterility. Summary: “Forced-air warming resulted in a significant mean increase in the temperature (1.1°C vs 0.4°C, p<0.0001) and number of particles (1038.2 vs 224.8, [...]
