ORVEWRAP+ Highly Effective in Maintaining Core Temperature of Hip Surgery Patients
Around 47,000 surgical site infections (SSIs) occur each year in England, according to the National Institute of Healthcare Excellence. Caused… Read news post
ORVEWRAP+ is a unique versatile six-layer laminated fabric passive warming blanket. It was developed with the expertise of clinicians and operational field medics to improve operational efficiencies whilst improving a patients recovery perioperatively.
ORVEWRAP+ is ideal where Forced Air Warming or other active warming is either not applicable or cost-effective or where a patient's temperature management is compromised.
By working with our clinical customers we are protecting and preventing patients against inadvertent hypothermia and its adverse effects. This offers better comfort and improves patient outcomes.
Clinical evidence is available that shows the efficacy for ORVEWRAP+ in maintaining a patient's normothermia.
ORVEWRAP+ provides a solution with simplicity in maintaining patients normothermia and comfort from consent to recovery.

Maintaining patient temperature above 36 degrees is crucial to reduce infection in surgical patients . A forced-air warming device (FAW) is routinely used to maintain temperature for spine surgery. Several studies have raised concerns about the potential for FAW devices to be a source of infection due to its effect on laminar flow and direct bacterial contamination of the machine’s hose . Resistive heating mattresses are an alternative that is difficult to use in prone spine surgery as the patient lies on two cushioned supports. We conducted a prospective trial of a new warming blanket (ORVEWRAP+) and compared it to a similar cohort of patients who had a standard approach using FAW.
50 consecutive patients undergoing various spine surgeries were studied. Precautions were taken to minimise exposure and heat loss during induction. Once turned prone on to cushions the patient's exposed body areas outside the surgical field were covered with warm cloth blankets over which an ORVEWRAP+ warming blanket cut in two was placed, over the thorax and lower limbs. ORVEWRAP+ is a unique six-layer laminate passive stand-alone warming blanket manufactured by Orvecare that is used to keep and maintain a patient in a normothermic state. Tympanic temperature was checked hourly and on arrival in recovery. The data obtained was compared to a similar consecutive cohort of patients using a FAW device. The primary outcome measure was the percentage of patients with a temperature above 36 degrees on arrival in recovery.
The control group had 40 lumbar and ten anterior cervical surgeries with an average procedure time of 163 minutes (67-270 min). 90% of the procedures took longer than two hours. The treatment group was similar with 43 lumbar surgeries, six anterior cervical surgeries and one anterior lumbar surgery. The average procedure time was 191 minutes (85-410min). In the control group, 3/50 patients had temperatures below 36 degrees, however, five patients were recorded as being hyperpyrexial (above 37.5 degrees) in recovery. In the treatment group, temperature was measured as below 36 degrees on arrival in recovery in 4/50 patients. No patients had temperatures above
This service evaluation demonstrated that in spine surgery, the use of a warming blanket (ORVEWRAP+) can achieve a high degree of compliance with the WHO standard for temperature management. The warming blankets are £13 cheaper than FAW and can save £8,000 in our institution.
