Study & Design
- Study Type
- Observational
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Diameter of femoral vein in each position.<br>Measurements will be made in real time. That is, the size and overlap over the vessels will be measured as soon as the leg has been placed in the selected position. The process of obtaining the ultrasound image takes 1-2 minutes but once the image is obtained, the measurements are made immediately on the frozen image.[Immediately upon obtaining a clear image of the femoral vein and artery]
- Secondary Outcome Measures
Name Time Method Proportion of overlap by femoral artery in each leg position. Both a) the total diameter of the vein and b) the diameter of the vein lying medial to the artery (ie not overlapped by the femoral artery) are measured in millimetres. The proportion of overlap is 1- (b/a).[Immediate - as above, the measurement is taken as soon as a clear image is obtained.]
