We compared the new self-warming Barrier<sup>®sup> EasyWarm<sup>®sup> blanket with passive thermal insulation with regard to perioperative patient body temperature in a multinational randomized clinical trial (n=246).
Secondary endpoints were incidence of perioperative hypothermia (<36°C) and patients' comfort level.
The Barrier<sup>®sup> EasyWarm<sup>®sup> blanket improved perioperative patient body temperature compared with standard hospital blankets (p<0.001). Intra- and postoperative incidence of hypothermia was reduced using the new actively warming blanket (p=0.001).
Patients' thermal comfort was improved with the Barrier<sup>®sup> EasyWarm<sup>®sup> blanket without serious adverse effects.
The new actively warming blanket seems feasible for prewarming of surgical patients and could be easily integrated in their perioperative clinical pathway.
