Comparison of Analgesia Efficacy of Transversus Abdominis Plane Block and Posterior Approach Quadratus Lumborum Block

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.
