Clinical study assessing the safety and efficacy of BARRIER® EasyWarm®
A clinical study to assess the safety and efficacy of BARRIER® EasyWarm®, an active self-warming blanket, shows that the use of this blanket helps to prevent hypothermia. 1
With the active self-warming blanket, intraoperative temperature was maintained at a stable level for 2.5 hours
The typical temperature drop of 1–1.5°C on induction of anaesthesia did not occur in patients. A temperature drop of only 0.6°C was recorded
No serious adverse events were reported
The active self-warming blanket was well received in terms of comfort and warmth by the patients
The study was performed in 2011 at the University General Hospital, in Houston, Texas and at the Physicians’ Surgical Care Center in Winter Park, Orlando, Florida, both in USA.
112 patients were enrolled and evaluated for safety and 68 were valid for protocol efficacy analysis.
The patients were scheduled to undergo general anaesthesia during a surgical procedure scheduled for a minimum of 60 minutes and maximum of 180 minutes. The schedule had to allow the subjects to be warmed with a fully activated blanket for at least 30 minutes prior to anaesthesia.
The typical temperature drop of 1-1.5°C on induction of anaesthesia did not happen. Only a drop of 0.6°C was recorded in this trial. It was concluded that temperature was maintained at a stable level for 2.5 hours during the period of surgery.1
