Ultrasound-guided Quadro-Iliac Plane Block for pain after lumbar instrumentation
Evaluation of the Effectiveness of Ultrasound-Guided Quadro-Iliac Plane Block in Postoperative Analgesia Management Following Lumbar Instrumentation Surgery

What this trial studies
Lumbar instrumentation commonly causes significant postoperative pain that can delay recovery and increase analgesic needs. In this interventional study, adults undergoing elective lumbar instrumentation under general anesthesia will receive an ultrasound-guided Quadro-Iliac Plane Block as part of their postoperative pain management. Investigators will record postoperative pain scores, opioid consumption, and any block-related complications to characterize analgesic effectiveness and safety. The results aim to clarify whether this newly described regional technique provides meaningful pain relief after lumbar spine surgery.
Who should consider this trial
Good fit: Adults classified ASA I–III scheduled for elective lumbar instrumentation under general anesthesia who can give informed consent and have no contraindications such as anticoagulant use, local infection, allergy to local anesthetics, diabetes, or significant renal/hepatic impairment are ideal candidates.
Not a fit: Patients on anticoagulants or with bleeding disorders, infection at the block site, pregnancy or lactation, prior lumbar surgery, diabetes, renal or hepatic impairment, or cognitive impairment limiting reliable pain reporting are unlikely to be eligible or to benefit from participation.
Why it matters
Potential benefit: If successful, this block could reduce postoperative pain and opioid requirements and support earlier mobilization after lumbar spine surgery.
How similar studies have performed: The Quadro-Iliac Plane Block is newly described and direct clinical data are limited, although other ultrasound-guided plane blocks for lumbar surgery have shown promising but variable reductions in pain and opioid use.
