Spots Global Cancer Trial Database for Comparison of Analgesia Efficacy of Transversus Abdominis Plane Block and Posterior Approach Quadratus Lumborum Block

Study Description

Brief Summary: Prostate cancer is the second most common cancer and the fifth in cancer-related deaths. Open radical retropubic prostatectomy is the most common surgical treatment for localized prostate cancer. Open radical retropubic prostatectomy is associated with moderate pain. Severe pain in the postoperative period affects the length of hospital stay and morbidity. Multimodal analgesia applications for the management of postoperative pain are the main component of post-surgical recovery. Different analgesia modalities, including systemic opioid use and neuraxial analgesia, have been used for pain control after retropubic radical prostatectomy. Side effects of systemic and intrathecal opioids limit the potential benefits of these agents. Transversus abdominis plane block and quadratus lumborum block are blocks that can be used for postoperative analgesia in the abdominal and pelvic regions. There is no study in the literature comparing the efficacy of these two blocks for postoperative analgesia in open radical retropubic prostatectomy and their effects on narcotic consumption.

Detailed Description: Scope: Open radical retropubic prostatectomy operation is associated with moderate postoperative pain and affects hospital stay and morbidity. Nerve blocks used for postoperative analgesia are one of the components of multimodal analgesia. Transversus abdominis plane block (TAP) is a regional block (T7-L1) that blocks the sensory afferents of the anterior abdominal wall. It was first introduced as an anatomical landmark-based technique through Petit's lumbar triangle. Since then, the ultrasound-guided block technique has been defined and the effectiveness of this block in postoperative pain control in abdominal and gynecological surgeries has been demonstrated. The sensory distribution of TAP block includes the incisional pain of open prostatectomy. TAP block technique has been shown to be a safe and effective method of postoperative analgesia in various general surgery, urological surgery, plastic surgery and pediatric surgery operations. In addition, postoperative pain management after lower abdominal surgeries has been recommended as part of ERAS protocols. Quadratus lumborum block (QL) is used as one of the postoperative pain methods after abdominal surgery in all age groups. It has been reported that QL block with a posterior approach extends more easily into the thoracic paravertebral space or the thoracolumbar plane and can create analgesia from T 7 to L 1. The use of posterior QL (QL-2) blocks for postoperative analgesia after open retropubic prostatectomy operations has not been studied before and it is not known which one is superior. The primary aim of this study was to compare the analgesic efficacy of transversus abdominis plane block and posterior approach quadratus lumborum block and opioid consumption within 24 hours postoperatively. The secondary aim is to determine whether there is a difference in terms of time to first analgesic consumption, duration of sensory block, opioid-related side effects (postoperative nausea and vomiting, itching, sedation), patient satisfaction, and complications related to the block.
