Nursing Journal: Forced-Air Warmers May Allow Pathogens to Contact Surgical Wounds

AORN Journal, noting concerns about infection risk from forced-air warmers, called for multi-center, randomized, controlled trials. Evidence of bacteria in the air-flow paths of forced-air warmers; authors ask manufacturers to consider redesign. In a continuing-education review article in the October issue of AORN Journal,published by the Association of Operating Room Nurses, the authors examined 192 sources.  Their [...]

Recent A & A study: “These findings warrant future research into the effects of forced air warming…during contamination-sensitive surgery.”

August 2013  Research in the August edition of Anesthesia & Analgesia, a publication of the International Anesthesia Research Society, and appearing under the name of the Anesthesia Patient Safety Foundation stated: “[F]orced air warming was found to establish convection currents that mobilized resident air from nonsterile areas (under the anesthesia drape) upward and into the surgical site.” The [...]

“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 [...]

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 [...]

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 [...]

Study Links Forced-air Warming to Infections: 3.8x Increase In Orthopedic Implant Cases

Previously, research studying the effects of forced-air warming on laminar flow operating theaters was limited to contamination…until now. The use of forced-air warming during orthopedic implant surgery was associated with a 3.8 times increase in deep joint infections as compared to warming patients without forced-air, according to a newly published study. The study, published in the [...]
