New nerve block may ease kids' pain after hip surgery
NCT ID NCT05832671
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether an ultrasound-guided erector spinae nerve block can reduce pain after hip reconstruction surgery in children aged 2-7. Seventy children were split into two groups: one received the new nerve block, the other a standard caudal block. Researchers measured pain scores, how soon kids needed extra pain medicine, and how calm they were waking up from anesthesia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Erector spinae muscle block (nerve block procedure)
- What this could lead to
- If it works well, this nerve block could become a standard way to manage pain after hip surgery in children, reducing the need for strong painkillers.
- What could go wrong
- This is a small, single-center study with only 70 children, so results may not apply to all kids or hospitals. Nerve blocks carry small risks like infection or bleeding.
