Mölnlycke Health Care introduces BARRIER® EasyWarm active self-warming blanket, a new innovative solution for patient warming

Mölnlycke Health Care launches a novel and uncomplicated solution for hospitals to maintain patients’ temperatures at a stable level before, during and after surgery thus helping to avoid hypothermia, a common side effect of anaesthesia induced surgery.1

Currently there is a limited range of warming products available for hospitals. Ordinary blankets are not very effective for operative care while other products for keeping body temperature are complicated and time consuming to use, often requiring extra equipment and regular maintenance. In addition, staff and patients often find them noisy and some of the solutions have a negative effect on air turbulence.2

The BARRIER EasyWarm blanket is easy to set-up and use, both for hospital staff and the patients. Once the package is opened and unfolded, the air activated blanket will self-warm to an average of 40° C within 30 minutes. There is no need for any extra equipment or devices and it will keep its temperature for up to 10 hours. This enables the blanket to follow the patient through the full peri-operative setting, i.e before, during and after surgery.

Overall, BARRIER EasyWarm active self-warming blanket is a simple and efficient solution for hospitals requiring no extra devices, no electricity and no maintenance. Furthermore, the EasyWarm has minimal effect on air turbulence, which means particles or microorganisms which can lead to infections might be spread.3


The importance of maintaining normal core body temperature

After induction of general anaesthesia, it is common that the patient’s core body temperature drops 1.5° C during the first hour of surgery. Peri-operative hypothermia, the status when a patient’s core body temperature drops to below 36° C, is a common complication of surgical procedures.3, 4

Peri-operative hypothermia is connected to poor outcomes for patients and an increase in surgical site infections. Increased risk of cardiac complications and bleeding, patients’ distress and discomfort, as well as elevated treatment costs and prolonged hospitalisation are other consequences of peri-operative hypothermia.4

It is well established that patients benefit from preventative measures such as, preoperative patient warming. Increasing the total heat of the body before surgery, reducing the drop in temperature as well as active warming during surgery, has shown to have a good effect on avoiding hypothermia. 5, 6

A clinical study to assess the safety and efficacy of the BARRIER EasyWarm active self-warming blanket used to prevent hypothermia demonstrates that BARRIER EasyWarm helps to prevent hypothermia. In the study, 112 patients at two US sites were enrolled, of which 68 where valid for efficacy analysis. The results show that the intraoperative temperature was maintained at a stable lever for 2.5 hours. Mean inclusion temperature of the patients was 36.5° C. After pre-warming of 30 minutes or more with the active self-warming blanket, the temperature drop was only 0.6° C. Furthermore, patients expressed a high level of comfort and just the right temperature. 1
