Quadro-Iliac Plane Block for Analgesia After Lumbar Microdiscectomy (QIPB RCT)

2026年7月29日 更新者：Engin Ihsan Turan、Kanuni Sultan Suleyman Training and Research Hospital

Effect of Ultrasound-Guided Quadro-Iliac Plane Block Compared With Local Infiltration Analgesia After Single-Level Lumbar Microdiscectomy: A Prospective, Double-Blind, Controlled, Multicenter Randomized Trial

This study will evaluate whether ultrasound-guided quadro-iliac plane block provides better postoperative pain control than local infiltration analgesia in patients undergoing single-level lumbar microdiscectomy.

Adult patients scheduled for elective single-level lumbar microdiscectomy will be randomly assigned to receive either bilateral quadro-iliac plane block plus patient-controlled analgesia or local infiltration analgesia plus patient-controlled analgesia. The main outcome of the study will be total fentanyl consumption during the first 24 hours after surgery. Pain scores, need for rescue analgesia, opioid-related side effects, patient satisfaction, and recovery quality will also be evaluated.

详细说明

This is a prospective, randomized, double-blind, controlled, multicenter clinical trial designed to assess the analgesic efficacy of ultrasound-guided quadro-iliac plane block in patients undergoing elective single-level lumbar microdiscectomy.

Patients aged 18-75 years with American Society of Anesthesiologists physical status I-III who are scheduled for elective single-level lumbar microdiscectomy under general anesthesia will be included. Participants will be randomized into two groups. The intervention group will receive bilateral ultrasound-guided quadro-iliac plane block before emergence from anesthesia, followed by postoperative patient-controlled analgesia. The control group will receive local infiltration analgesia performed by the surgeon, followed by postoperative patient-controlled analgesia.

All patients will receive a standardized general anesthesia protocol. Postoperative analgesia will be provided using a fentanyl-based patient-controlled analgesia device. The primary outcome will be total fentanyl consumption during the first postoperative 24 hours. Secondary outcomes will include numerical rating scale pain scores at predefined postoperative time points, rescue analgesic requirement, opioid-related adverse effects such as nausea, vomiting, pruritus and respiratory depression, dermatomal sensory spread, and patient-reported recovery quality using the QoR-15 questionnaire.

武器和干预

参与者组/臂
干预/治疗
有源比较器：Quadro-Iliac Plane Block Group
Participants in this group will receive bilateral ultrasound-guided quadro-iliac plane block before emergence from general anesthesia, followed by postoperative fentanyl-based patient-controlled analgesia.
程序：Ultrasound-Guided Quadro-Iliac Plane Block
Bilateral ultrasound-guided quadro-iliac plane block will be performed before emergence from general anesthesia in the prone position. After visualization of the quadratus lumborum muscle and iliac crest at the L3 level, 30 mL of 0.167% bupivacaine will be injected into the interfascial plane on each side. All participants will receive postoperative fentanyl-based patient-controlled analgesia.
有源比较器：Local Infiltration Analgesia Group
Participants in this group will receive surgeon-performed local infiltration analgesia, followed by postoperative fentanyl-based patient-controlled analgesia.
程序：Local Infiltration Analgesia (LIA)
Local infiltration analgesia will be performed by the surgeon before the end of surgery. A total dose of 50 mg of 0.25% bupivacaine will be infiltrated into the subcutaneous tissue. All participants will receive postoperative fentanyl-based patient-controlled analgesia.

主要结果指标

结果测量
措施说明
大体时间
Total Fentanyl Consumption During the First 24 Hours After Surgery
大体时间：Postoperative 0-24 hours
Total postoperative fentanyl consumption administered via patient-controlled analgesia will be recorded during the first 24 hours after surgery.
Postoperative 0-24 hours

次要结果测量

结果测量
措施说明
大体时间
Postoperative Pain Scores at Rest and During Movement
大体时间：Postoperative 0, 1, 6, 12, and 24 hours
Pain intensity will be assessed using the Numerical Rating Scale at rest and during movement. The scale ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
Postoperative 0, 1, 6, 12, and 24 hours
Opioid-Related Adverse Effects
大体时间：Postoperative 0-24 hours
Opioid-related adverse effects, including nausea, vomiting, pruritus, and respiratory depression, will be recorded.
Postoperative 0-24 hours
Dermatomal Sensory Spread
大体时间：Postoperative 2 hours
Dermatomal sensory spread of the block will be evaluated using a cold test.
Postoperative 2 hours
Number of Patients Require Rescue Analgesic
大体时间：Postoperative 0-24 hours
The need for rescue analgesia with intravenous tenoxicam will be recorded during the postoperative follow-up period.
Postoperative 0-24 hours
Quality of Recovery Score
大体时间：Postoperative 24 hours
Patient-reported recovery quality will be assessed using the Quality of Recovery-15 questionnaire (0-150). Higher value means better Quality of Recovery.
Postoperative 24 hours
