Nerve block could cut opioid need after hip fracture surgery
NCT ID NCT07716540
First seen Jul 21, 2026 · Last updated Jul 31, 2026 · Updated 3 times
Summary
This study tests whether a specific nerve block, called the deep iliacus plane block, can reduce the amount of opioid pain medication needed after hip fracture surgery. Half of the participants receive the real block with bupivacaine, while the other half receive a sham (fake) block. The goal is to see if this approach leads to less pain and fewer opioid-related side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- an ultrasound-guided deep iliacus plane block using bupivacaine
- What this could lead to
- If effective, this nerve block could reduce the need for opioid painkillers after hip fracture surgery, leading to faster recovery and fewer side effects.
- What could go wrong
- This is a small, early-stage trial with only 52 participants, so results may not apply to all patients. The block may not provide significant pain relief over standard care.
