About this study
This randomized comparative study evaluated supraclavicular brachial plexus block using three techniques in patients undergoing elbow and below-elbow surgeries. A total of 75 patients were included and allocated into three groups: Group A received a peripheral nerve stimulator (PNS)-guided block, Group B received an ultrasound-guided (USG) block, and Group C received a combined USG and PNS-guided block. The three techniques were compared with respect to ease of administration, success rate and quality of block, including duration of analgesia.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This randomized comparative study evaluated supraclavicular brachial plexus block using three techniques in patients undergoing elbow and below-elbow surgeries. A total of 75 patients were included and allocated into three groups: Group A received a peripheral nerve stimulator (PNS)-guided block, Group B received an ultrasound-guided (USG) block, and Group C received a combined USG and PNS-guided block. The three techniques were compared with respect to ease of administration, success rate and quality of block, including duration of analgesia.

Questions about this trial
What is this clinical trial studying?
A study testing Peripheral Nerve Stimulator-Guided Supraclavicular Brachial Plexus Block, Ultrasound-Guided Supraclavicular Brachial Plexus Block and Combined Ultrasound and Peripheral Nerve Stimulator-Guided Supraclavicular Brachial Plexus Block in people with Supraclavicular Brachial Plexus Block, run by Pravara Institute of Medical Sciences University at 1 site in India.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 0 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in India. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Success of supraclavicular brachial plexus block (time frame: Within 30 minutes after completion of the supraclavicular brachial plexus block). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026.
