Effect of a Sacral Lift on Femoral Vein Size and Exposure
United States35 participantsStarted 2025-07-23
Plain-language summary
The goal of this clinical trial is to learn if a sacral lift can improve femoral vein size and exposure, which may be clinically helpful during femoral vein cannulation among emergency department patients. The main questions it aims to answer are:
Does a sacral lift increase femoral vein size compared to no sacral lift in both straight and frog-leg positions? Does a sacral lift improve femoral vein exposure (reduce overlap by the femoral artery) compared to no sacral lift in both straight and frog-leg positions? Researchers will compare femoral vein size and exposure measurements with and without a sacral lift in both straight and frog-leg leg positions to see if the sacral lift improves vein size and reduces artery overlap.
Participants will:
Undergo femoral vein ultrasound scans. Maintain a straight leg position with and without a sacral lift. Maintain a frog-leg position with and without a sacral lift.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult emergency department patients.
Exclusion Criteria:
* \<18 or \>85 years-old
* Anyone with a history of: deep venous thrombosis (DVT), May-Thurner syndrome, lower extremity vein harvesting, arterial or venous surgery of the lower leg (e.g., peripheral arterial stent placement or sclerotherapy of lower extremity varicose veins), or peripheral vascular disease.
* Anyone with a medical condition that could impact their physical ability to lay supine or abduct and externally rotate their hips safely (e.g., hip fracture).
* Anyone whose femoral vessels cannot be clearly identified using a linear transducer
* Anyone whose femoral vein is not compressible on the study ultrasound (indicating a DVT).
* Vulnerable populations such as pregnant women and those who cannot consent.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
