Ultrasound Description of the Sciatic Nerve
Stopped: No subjects were enrolled. Sciatic blocks infrequently used for pain control.
0Started 2009-04
Plain-language summary
Sciatic nerve blocks are frequently used for anesthesia or analgesia for surgery of the lower legs. Currently, if ultrasound is used to find the sciatic nerve, the leg must be raised to locate the nerve with the ultrasound probe on the back of the thigh. In pediatric surgery, the patients are anesthetized (asleep) before the block is given. It is difficult for one person to administer the sciatic nerve block using this method. We would like to identify the sciatic nerve using ultrasound on the side of the thigh and its location to the adjacent structures.

Inclusion criteria
. Males or females 11 to 17 years old.
. Patients undergoing lower extremity surgery who are scheduled to have a sciatic nerve block as part of the anesthetic.
. Parental/guardian permission (verbal consent) and child assent. Note: if you record ANY PHI, you will need to obtain written consent since HIPAA requires written authorization for use of PHI.
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.
What they're measuring
1
The primary objective is to describe the appearance of the sciatic nerve and its location in relation to adjacent anatomic structures using ultrasound from the lateral mid-thigh position.
