Onset Time of Nerve Block: A Comparison of Two Injection Locations in Patients Having Lower Leg/ Foot Surgery

United States76 participantsStarted 2014-05

Plain-language summary

The purpose of this study is to compare injecting local anesthetic (numbing medication) in different patterns around a major nerve in the leg. Patients who undergo surgery to the lower leg and/or foot are usually offered the option of a nerve block to help with pain control after surgery. A nerve block involves injecting local anesthetic (numbing medicine) by a nerve or nerves that provide sensation to the area where surgery will be performed. The local anesthetic (numbing medication) numbs up the area where the surgery is performed and helps decrease the amount of pain felt after surgery. The local anesthetic (numbing medication) can be injected in various patterns by a nerve, such as in one spot by a nerve or completely surrounding a nerve. The local anesthetic will be either injected around the sciatic nerve or will injected in a way that will split the sciatic nerve into the two component nerves that make it up, the tibial and sciatic, and surrounds each nerve. The hypothesis is that subjects in the group that local anesthetic is injected in a pattern that separates the sciatic nerve into the two component nerves may have a faster onset time of regional anesthesia and block success than subjects in the group that have the local anesthetic injected at around the nerve.

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.
