Frequently asked questions

About one of every 100 patients develops an infection after surgery.* Rates will vary depending on the type of surgery and the patient’s risk factors.

Many factors can cause a surgical site infection. Everyone has bacteria in their bodies. The majority of surgical site infections come from the patient’s own bacteria.

When the skin is opened, bacteria in the body can migrate to the surgical wound. A number of factors are known to increase the risk of surgical site infections, including having other medical problems or diseases such as diabetes, high blood pressure or heart disease; or being elderly; overweight or a smoker.

The 3M™ Bair Hugger™ Patient Warming System is used to keep patients warm before, during, and after surgery.

The system draws in the filtered air of the operating room, passes it through an internal filter and warms that air to the selected temperature.

The warmed air flows to a single-use 3M™ Bair Hugger™ Warming Blanket through an enclosed hose, and is then gently dispersed across the surface of the skin.

The 3M™ Bair Hugger™ Patient Warming System does not disrupt the air flow in the operating room.

A widely accepted practice for reducing the risk of infection is to maintain a surgical patient’s core body temperature greater than 36° C (96.8° F) throughout the surgical procedure. Keeping people warm during surgery can, in fact, reduce the risk of infections, reduce the length of hospital stays and improve overall outcomes from surgery.

Numerous healthcare professional organizations have recommended the use of forced-air warming to safely and effectively maintain a patient’s normal body temperature during surgery.*

No. There is no evidence that the 3M™ Bair Hugger™ Patient Warming System forced-air warming causes infections.

In fact, scientific literature suggests that maintaining normal body temperature during surgery can have numerous benefits that include a reduction in the rate of postoperative infections, reduced blood loss, a reduction in the possibility of heart attacks, shorter recovery times and lower mortality rates.*

The 3M™ Bair Hugger™ Patient Warming System is a safe and effective method of maintaining normal body temperature during surgery. Visit fawfacts.com to learn the truth about forced-air warming (US, English only).
