mTLIP vs QIPB for Postoperative Analgesia After Lumbar Instrumentation Surgery
Starting soon · Not applicable
Conditions studied: Pain, Postoperative
In brief
Lumbar instrumentation surgery is associated with severe postoperative pain due to extensive tissue dissection and prolonged muscle retraction during the procedure. Inadequate postoperative pain control may result in delayed mobilization, increased cardiopulmonary complications, and prolonged hospital stay. Ultrasound-guided regional analgesia techniques are increasingly used to improve postoperative pain management after lumbar spine surgery. The thoracolumbar interfascial plane (TLIP) block has been shown to provide effective analgesia for lumbar instrumentation surgery, and its modified technique (mTLIP) has been reported to enhance postoperative pain control. The quadro-iliac plane (QIP) block is a newly described fascial plane block with promising results in lumbar spine surgery. This randomized controlled trial aims to compare the postoperative analgesic effectiveness of the modified thoracolumbar interfascial plane block and the quadro-iliac plane block in patients undergoing lumbar instrumentation surgery.
