The 3M Bair Hugger, manufactured by 3M subsidiary Arizant Healthcare, is a force hot air warming blanket, used primarily to help maintain a patient’s body temperature during surgery. The 3M Bair Hugger pushes warm air through a flexible hose into a blanket draped over a patient.
However, warming blankets can recirculate contaminated air over a patient’s body, including over an open surgical site. This may result in infections like MRSA or sepsis. In particular, patients undergoing knee or hip replacement surgery are at risk of infections deep in the joint, which is very difficult to treat. Complications from these infections include hospitalization, implant revision surgery, limited mobility, permanent disability, amputation and death.
