New pain block may cut opioid use after common buttock surgery
NCT ID NCT07534488
First seen Jun 27, 2026 · Last updated Jul 28, 2026 · Updated 2 times
Summary
This study tests whether an ultrasound-guided nerve block (sacral erector spinae plane block) can reduce pain and the need for strong painkillers after pilonidal sinus surgery. Sixty adults having elective surgery will be randomly assigned to receive either the block plus standard care or standard care alone. The main goal is to see if the block lowers the amount of rescue opioid medication needed after surgery.
