简要总结
Chronic venous leg ulcers (VLU) are painful, debilitating wounds that place a significant burden on the patient, their family, and healthcare resources. Treating VLU can present a significant challenge to clinicians, who currently have a limited range of treatments at their disposal. The mainstay of treatment is compression bandaging, ambulation and elevation at rest. In addition to the aforementioned, intermittent pneumatic compression has also been utilised1. When applied to the leg or foot intermittent pneumatic compression (IPC) devices intermittently inflate and deflate to increase venous return. These devices can be uncomfortable to wear, and compliance can be inhibited because of size, weight and external power source that limit the patient's mobility. In patients who cannot walk, or in those who are unable to tolerate compression bandaging, ulcers may deteriorate and never heal. Accordingly, there is a need for novel, alternative devices or strategies that can be used to complement or replace compression bandage therapy.
详细描述
This is a single-centre randomised intra-patient comparison of gekoTM plus R-2 R-2 and IPC.
Blood flow will be measured after each device has been activated for 10 minutes with a 10 minute rest between devices to allow blood flow to return to baseline. The order the devices will be fitted is determined randomly. Activation of the device for 10 minutes before measurement is deemed appropriate as previous studies have demonstrated significant increases in blood flow following as little as five minutes use of the devices.
In this short study the standard of care (typically compression bandaging), will be suspended temporarily to allow the fitting of the gekoTM plus R-2 and IPC devices in order to measure blood flow. This is not seen as a risk to the patient as the device is only in operation for 30 minutes plus 10 minutes rest within the care pathway.

结局指标
主要结局
The lower limb blood flow between gekoTM plus R-2 and IPC devices in VLU patients will be assessed.
时间窗: 3 months
Duplex ultrasound of the femoral vein and artery will be performed with bilateral recording of blood flow velocity. After 10 minutes activation of either geko™ or IPC and after the 10 minutes the devices will swapped over and measurements performed. All measurements to be carried out in triplicate.
