Dexmedetomidine versus dexamethasone added to ropivacaine for supraclavicular nerve block in upper‑limb surgery

Official title: Comparative Analysis Of Dexmedetomidine And Dexamethasone As An Adjuvant To 0.5%Ropivacaine On Onset Of Ultrasound Guided Supraclavicular Brachial Plexus Block In Patients Undergoing Upper Limb Surgeries

Run by Sahiwal medical college sahiwal · NCT07290595 · Data updated 2026-11-12

This test compares two medicines added to ropivacaine to see which gives faster onset and longer pain relief for adults having upper‑limb surgery with an ultrasound‑guided supraclavicular nerve block.

Is this trial a fit for you?

Likely a good fit

Adults 18–70 years old, ASA class I–III, non‑pregnant, scheduled for upper‑limb surgery below the mid‑humerus and willing to receive an ultrasound‑guided supraclavicular brachial plexus block.

Probably not a fit

People with ischemic heart disease, bleeding disorders, infection at the block site, pre‑existing upper‑limb neuropathy, allergy to the study drugs, pregnant patients, or those unable to travel to the study site are unlikely to be eligible or benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults scheduled for upper‑limb surgery below the mid‑humerus are randomized to receive 28 ml of 0.5% ropivacaine with either 1 mcg/kg dexmedetomidine or 8 mg dexamethasone using an ultrasound‑guided supraclavicular brachial plexus block. Drugs are prepared and coded by one anesthetist so the clinician performing and observing the block is blinded to the assignment. The trial records onset time of sensory and motor block, duration of postoperative analgesia, and hemodynamic effects including bradycardia and hypotension. Standard monitoring and exclusion criteria (pre‑existing neuropathy, infection at the site, ischemic heart disease, coagulopathy, pregnancy, or allergy) are applied to maintain safety.

Why it matters

Potential benefit: If one adjuvant proves superior, patients could get faster‑acting, longer‑lasting regional anesthesia with less need for opioids and improved postoperative comfort.

How similar studies have gone: Numerous prior trials have shown that both perineural dexmedetomidine and dexamethasone can prolong peripheral nerve block duration, but head‑to‑head comparisons have produced mixed results.
