Study Overview
Brief Summary
Abdominal wall hernias are common, with a prevalence of 1.7% for all ages and 4% for those aged over 45 years. Inguinal hernias account for 75% of abdominal wall hernias, with a lifetime risk of 27% in men and 3% in women. Repair of inguinal hernia is one of the most common operations in general surgery
Detailed Description
The peripheral nerve block usage is increasing in popularity because it decreases pain as estimated by visual analogue scores/numerical rating pain scores postoperatively and decreases the need for postoperative analgesic usage thereby reducing opioid induced side effects like postoperative respiratory depression, nausea, vomiting, NSAID induced gastritis etc. Nerve blocks also shorten Post-Anesthesia Care Unit stay time, and also increases patient satisfaction .
Ultrasound-guided peripheral nerve blocks including ilioinguinal/ iliohypogastric nerve block and transversus abdominis plane block have been widely used and considered as effective traditional techniques for postoperative analgesia in inguinal hernia repair .
In recent years, the quadratus lumborum (QL) block is proposed to be an alternative regional block for both upper abdominal surgery and lower abdominal surgery.
The blockade of ilioinguinal/iliohypogastric nerves in the anterior abdominal wall has improved postoperative analgesia after open inguinal hernia repair and many other procedures.
The Quadratus Lumborum (QL) Block is a regional anesthetic technique which described by anesthesiologist "DR Rafael Blanco" in 2007. Quadratus Lumborum block allows the local anesthetic agent to spread between the posterior aspect of the Quadratus Lumborum muscle and the middle layer of the Thoracolumbar fascia, which is nearer to the thoracic paravertebral space. It has four approaches based on the point of drug deposition in relation to quadratus lumborum muscle. Drug is deposited on the anterolateral, posterior, anterior to the Quadratus Lumborum muscle in the three approaches. In fourth approach drug is deposited intramuscularly. It provides postoperative analgesia for longer duration .

Outcomes
Primary Outcomes
Post Operative Pain
Time Frame: 0 hour after the operation up to 24-hour analgesic after surgery
All patients will be familiar with the use of the visual analogue scale score identifying 0 as no pain and 10 as worst imaginable pain.
Secondary Outcomes
No secondary outcomes reported
