Comparative Study Between Ultrasound Guided Quadratus Lumborum Versus Ilioingunial/ Iliohypogastric Nerves Block as Post-operative Analgesia for Patients Undergoing Inguinal Hernia Repair Surgeries
Sponsor: Ain Shams University
Summary
Postoperative pain management is becoming an integral part of anesthesia care. Various techniques of pain relief have been designed. We have designed the study for comparison between ultrasound guided quadratus lumborum (QL) block versus Ultrasound-guided ilioinguinal and iliohypogastric nerves (ILI+IHG) block as regard postoperative pain block and opioid consumption in patients undergoing inguinal hernia repair under general anesthesia.

Interventions
Sonar guided Quadratus Lumborum block
The probe will be tilted down the lateral abdomen to identify a bright hyperechoic line that represents the middle layer of the thoracolumbar fascia. The needle will be inserted in plane from anterolateral to posteromedial. The needle tip will be placed between the thoracolumbar fascia and the QL muscle, and after negative aspiration, the correct position of the needle will be proved by injection of 5 mL of normal saline to confirm the space with a hypoechoic image and hydrodissection. An injection of (0.2 mL/kg of 0.25% bupivacaine per side) will be applied without exceeding the toxic dose 3 mg/kg
Sonar guided Ilioinguinal/Iliohypogastric block
The ultrasound linear probe will be placed over the anterior superior iliac spine with the superior margin of the transducer pointed directly in an oblique plane toward the umbilicus. The iliohypogastric nerve will be seen medial to the ilioinguinal nerve. The overlying skin will be prepared with antiseptic solution and 21 gauge 120mm Locoplex Sono Tap cannula will be advanced using an in-plane approach from a point just below the inferior border of the transducer toward the ilioinguinal nerve as it lies within the facial plane between the internal abdominal oblique and transverse abdominis muscles. After negative aspiration, (0.2 mL/kg of 0.25% bupivacaine per side) will be injected without exceeding the toxic dose of 3 mg/kg
