NCT ID NCT07343570
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of ultrasound-guided nerve blocks to control pain after open inguinal hernia repair. 66 adults will receive either a lateral quadratus lumborum block or a combined ilio-inguinal/ilio-hypogastric/genitofemoral block. The goal is to see which method reduces the need for opioid painkillers in the first 24 hours after surgery.
