Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, quadratus lumborum block (QLB), transversus abdominis plane (TAP) block, and local anesthetic infiltration will be performed preoperatively in patients who will undergo unilateral inguinal herniorrhaphy operation under general anesthesia. Quality of recovery (QoR-15) score, postoperative acute and chronic pain levels will be evaluated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Inguinal hernia repair, one of the most common operations, causes moderate to severe postoperative pain. The postoperative pain delays patients' recovery and return to daily life, increases the rate of readmission to the hospital, and can lead to persistent postoperative pain.Procedure-specific postoperative pain management (PROSPECT) recommendations for optimal pain management have been recently updated. Accordingly, in addition to preoperative or intraoperative paracetamol and nonsteroidal anti-inflammatory analgesics, local anesthetic infiltration and/or regional analgesia techniques (ilio-inguinal nerve blocks or TAP block) with rescue opioids are recommended. Also, it has been reported that further research is needed on new regional techniques (other fascial plane blocks etc).It has been shown that QLB potentially results in extensive sensory blockade (T7-12), and in cadaver studies, the iliohypogastric and ilioinguinal nerves are constantly involved. In addition, there are studies suggesting that it provides much longer analgesia than TAP block. There are few studies on its efficacy in inguinal hernia repair that are in pediatric cases or performed in addition to central blocks. It is hypothesized that QLB may provide better and longer analgesia, may increase the quality of recovery and reduce the development of resistant chronic pain, compared to other regional methods such as local infiltration or TAP block, that proven effectiveness.
