Summary

Lumbar instrumentation surgery is associated with significant postoperative pain. This study evaluates the analgesic effectiveness of the ultrasound-guided Quadro-Iliac Plane Block in patients undergoing lumbar instrumentation surgery, aiming to assess the efficacy of this newly developed technique for postoperative pain management.

Detailed description

Lumbar instrumentation surgery is associated with significant postoperative pain, which may reduce patient comfort, delay early mobilization, and increase analgesic requirements. Effective postoperative pain management is essential for enhancing recovery and reducing postoperative morbidity. In this context, regional anesthesia techniques have become an important component of multimodal analgesia strategies. The Quadro-Iliac Plane Block is a newly described ultrasound-guided regional analgesia technique. This block aims to provide effective analgesia by targeting the relevant branches of the lumbar nerves supplying the surgical area. However, clinical evidence regarding its effectiveness in postoperative analgesia following lumbar instrumentation surgery remains limited. This study aims to evaluate the postoperative analgesic effectiveness of the ultrasound-guided Quadro-Iliac Plane Block in patients undergoing lumbar instrumentation surgery. The findings of this study are expected to contribute to the assessment of this newly developed technique as a safe and effective option for postoperative pain management in lumbar spine surgery.
