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 by microorganisms and bacteria that make their way into the body via surgical incisions, SSIs result in patients being in pain and hospital for longer. Meanwhile, the costs of postoperative patient care rack up for an already strained national healthcare service.

The good news is that SSIs are preventable. In their November 2016 guidelines, WHO recommended that maintaining a core body temperature of 36 degrees and above played a crucial factor in the prevention of SSIs.

And, this is where Orvecare comes in.

Our ORVEWRAP+® blanket has been clinically proven to be a highly effective way of preventing heat loss in patients undergoing hip replacement surgery – just one of the operations that can be prone to SSIs.

Today, we’re taking a closer look at the evaluation of the ORVEWRAP+® warming blanket for temperature management during hip arthroplasty.

We conducted this research in partnership with the Robert Jones and Agnes Hunt Orthopaedic Hospital in Shropshire.

What is ORVEWRAP+?

ORVEWRAP+ is a cost-effective patient warming blanket that ensures patient normothermia from consent, right through to recovery.

It works by capturing body heat before an anaesthetic is administered to a patient, then distributing and maintaining the body’s temperature during and after surgery.

The simple blanket design of ORVEWRAP+® means that it passively warms patients without requiring a secondary heat source, preventing redistribution temperature drop and heat loss from uncovered extremities.

About the study.

The standard way of patient warming for hip surgery at RJAH is using a resistive heating mattress combined with warm cloth blankets placed on the top half of the body.

While effective, the issue with resistive heating mattresses is that they only work by heating the parts of the body that are in direct contact with them.

Additionally, hip surgery patients are placed lateral (on their side), so the area of the body that is in contact with the heated mattress is limited, and this may have an impact on the ability to adequately warm the patient.

Furthermore, the warm cloth blankets do not possess the same thermal properties as an ORVEWRAP+® blanket.

During the study, 24 patients undergoing hip arthroplasty between January and November 2017 were compared to 25 patients from January to November 2018.

All patients were covered with a warm cloth blanket on arrival, but once the patient was anaesthetised, an ORVEWRAP+® was used to cover the upper torso.

The results of the study showed that the use of ORVEWRAP+® alongside a heated mattress and warm cloth blankets was an effective way to comply with WHO standards.

Furthermore, RJAH found that the current technique of only using a heated mattress was inferior without ORVEWRAP+®.

In fact, 96% of patients undergoing hip replacement surgery during this evaluation maintained a core temperature of 36 degrees.

This has led RJAH to recommend the use of ORVEWRAP+® as a supplement to the heating mattress for this type of operation.
