Prevent perioperative hypothermia with BARRIER® EasyWarm®

The following information is intended for Healthcare professionals.

Pre-operative warming is a crucial aspect of patient care that significantly impacts surgical outcomes.

Here are five key reasons why pre-operative warming with BARRIER® EasyWarm® active warming blankets is so critical.

  • 1. Prevention of hypothermia

    Hypothermia can occur during surgery due to the effects of anaesthesia, as well as the cold operating room environment2. Pre-operative warming helps maintain normothermia, reducing the risk of hypothermia and its associated complications3.

    2. Reduced risk of surgical site infections

    Maintaining a normal body temperature may reduce the incidence of surgical site infections. Hypothermia can impair the immune response and decrease blood flow to the surgical site, increasing the risk of infection2.

    3. Improved anaesthetic outcomes

    Anaesthesia can cause vasodilation and heat loss, leading to hypothermia2. Pre-operative warming helps counteract these effects, ensuring that the patient remains warm and comfortable throughout the procedure. This can lead to a smoother recovery3.

    4. Enhanced patient comfort

    Patients who are warm before surgery experience less anxiety and discomfort4. Pre-operative warming can improve overall patient satisfaction and contribute to a more positive surgical experience.

    5. Reduction in post-operative complications

    Hypothermia is associated with various post-operative complications, including increased blood loss and need for transfusions, prolonged hospital stays, and higher rates of morbidity and mortality2. By preventing hypothermia, pre-operative warming can reduce these risks and improve overall surgical outcomes3.

    Using BARRIER® EasyWarm® active warming blankets for pre-operative warming is a simple yet effective intervention that plays a vital role in enhancing patient safety and improving surgical outcomes.
