Predictive Value Of Muscle Tone And Perfusion Index In Supraclavicular Block Success.

Mexico33 participantsStarted 2023-03-01

Plain-language summary

The goal of this observational study is to define the usefulness of a new device to predict the supraclavicular block successfulness in the patients scheduled to orthopedic surgery. The main question it aims to answer is: ¿The combination between a flexometer and perfusion index is capable to predict the successfulness of a supraclavicular block in the first 15 min? Participants will be anesthetized by residents or anesthesiologist with regional anesthesia training and then connected to a flexometer to measure the motor blockade and a pulse oximeter to measure the perfusion index related to sympathetic blockage at 0, 5, 10 and 15 min .

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * patients with 18 years and older. * ASA 1, 2, and 3. * patients who required surgical intervention in the distal two-thirds of an upper limb and warranted the application of an ultrasound-guided supraclavicular brachial plexus block. Exclusion Criteria: * infection at the puncture site * allergy to local anesthetics * diagnosis of coagulopathy * restrictive pulmonary pathology * diaphragmatic pathology * dependence on supplemental oxygen * brachial plexus radiculopathy * uncontrolled type 2 diabetes mellitus

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.
