IPC-CALF Versus GEKO in Post-op Total Hip Patients

Study Overview
=================
Brief Summary
-----------------
This study is designed to compare the effect of IPC on post-operative circulation in lower limbs with gekoTM device after total hip replacement procedure.

Conditions
-----------------
Total Hip Replacement

Intervention / Treatment
-----------------
* Device: geko
* Device: IPC-Calf

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Ultra sound measurements of haemodynamics |  | 10mins | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Adverse event rate |  | 3 hrs | 
| patient rated tolerability | A questionnaire has been designed to record the opinion of the patient with regard to both devices, in particular how comfortable the devices were to wear. The patient will be asked to rate how comfortable the devices are to wear on a scale of 1-5, 1 being very comfortable and 5 being extremely uncomfortable | 3 hrs |
