PENG nerve block plus dexmedetomidine for hip surgery pain in older adults
Official title: Effect of Perineural Dexmedetomidine as an Adjuvant to Pericapsular Nerve Group Block in Older Adults: A Randomized Controlled Trial
Run by Poznan University of Medical Sciences · NCT07327372 · Data updated 2026-11-12
This will test whether adding a small dose of dexmedetomidine to a PENG nerve block gives longer, better pain relief and reduces opioid need for people 65 and older having hip surgery.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 65 or older scheduled for elective or emergency hip surgery who can provide informed consent and have no contraindication to a PENG block or the study medications.
✕Probably not a fit
Patients with allergies to ropivacaine or dexmedetomidine, pre-existing neurologic deficits in the limb, significant coagulopathy, severe hepatic or renal failure, chronic daily opioid use, severe cognitive impairment, or BMI over 40 would not be eligible and are unlikely to receive benefit from this protocol.

What this trial studies
This is a prospective, randomized, controlled trial in older adults undergoing hip surgery comparing a PENG block with ropivacaine alone versus ropivacaine plus low-dose dexmedetomidine. Participants 65 years and older who are eligible for a PENG block will be randomly assigned to one of the two regimens and followed for postoperative pain scores, opioid consumption, motor function, and complications. The trial is single-center at Poznan University of Medical Sciences and uses ultrasound-guided PENG block as part of multimodal perioperative analgesia. Safety monitoring will include assessment for hemodynamic effects, neurologic status, and adverse events related to regional anesthesia and study drugs.
Why it matters
Potential benefit: If successful, adding dexmedetomidine could prolong analgesia, lower opioid use, and help older patients mobilize sooner after hip surgery.
How similar studies have gone: Other regional hip-block techniques and small trials of dexmedetomidine as an adjuvant have shown prolonged analgesia and reduced opioid use, but data specifically on dexmedetomidine added to the PENG block in older adults are limited.
