Official title
Comparing Ultrasound-guided Lateral Quadratus Lumborum Block Versus Combined Ilio-inguinal/Ilio-hypogastric /Genitofemoral Block for Postoperative Analgesia After Open Inguinal Hernia Repair: A Double-blind Randomized Controlled Trial
Overview
This double-blind randomized controlled trial aimes to compares two ultrasound-guided regional techniques-lateral quadratus lumborum block versus combined ilio-inguinal/ilio-hypogastric/genitofemoral (II-IH-GFN) block-for postoperative analgesia after elective unilateral open inguinal hernia repair under spinal anesthesia in adults.
Interventions
- Procedure Ultrasound-guided lateral quadratus lumborum block
Ultrasound-guided lateral quadratus lumborum block. Local anesthetic: 30 ml of (Ropivacaine 0.2%) is injected at the appropriate fascial level. - Procedure Combined ilio-inguinal/ilio-hypogastric/genitofemoral (II-IH-GFN) block
Ultrasound-guided ilio-inguinal and ilio-hypogastric block. Local anesthesia: 20 ml of 0.2% ropivacaine for ilio-inguinal and ilio-hypogastric block + 10 ml of 0.2% ropivacaine for genitofemoral anaesthesia, total injection volume = 30 ml.
Primary outcome measures
- Cumulative opioid consumption in the first 24 hours postoperatively [Time frame: 24 hours after surgery.]
Secondary outcome measures (8)
- Pain intensity (VAS pain scores at rest ) [Time frame: 24 hours postoperatively.]
- Pain intensity (VAS pain scores at movement) [Time frame: 24 hours postoperatively.]
- Time to first analgesic request [Time frame: 24 hours.]
- Proportion of patients requiring rescue opioid analgesia [Time frame: 24 hours.]
- Incidence of postoperative block-related complications [Time frame: 24 hours.]
- Patient satisfaction score [Time frame: Assessed at 24 hours postoperatively.]
- Post-anesthesia care unit (PACU) stay duration [Time frame: 24 hours]
- Total hospital stay duration [Time frame: 24 hours]
