About this trial
This study compares two regional anesthesia techniques used for pain control after lumbar spine surgery: the classic thoracolumbar interfascial plane (TLIP) block and the quadratus lumborum-iliac plane (QIP) block. Patients between 18 and 65 years of age who undergo elective lumbar discectomy (up to two spinal levels) will be observed based on which block their treating anesthesiologist chooses to use as part of routine clinical practice. No randomization or additional intervention beyond standard care will be performed. Researchers will record the total amount of opioid pain medication used in the first 24 hours after surgery, the time until the first request for pain medication, pain scores at several time points after surgery (0, 1, 2, 4, 8, 12, and 24 hours), and any side effects (such as nausea, vomiting, or sedation) or complications related to the block. The aim is to compare the effectiveness and safety of these two techniques in reducing pain and opioid use after lumbar spine surgery.

Treatments tested in this trial
Thoracolumbar Interfascial Plane (TLIP) Block of bupivacaine
Procedure/SurgeryUltrasound-guided injection of 20 mL bilaterally (40 mL total) of 0.25% bupivacaine into the fascial plane between the multifidus and longissimus muscles at the relevant lumbar level, performed at the end of surgery before emergence from anesthesia, as part of routine postoperative analgesia.
Quadratus Lumborum-Iliac Plane (QIP) Block
Procedure/SurgeryUltrasound-guided injection of 20 mL bilaterally (40 mL total) of 0.25% bupivacaine into the interfascial plane between the erector spinae and quadratus lumborum muscles at the iliac crest level, performed at the end of surgery before emergence from anesthesia, as part of routine postoperative analgesia.
Treatment groups
60 Participants
are divided into 2 treatment groupsGroup A: TLIP Block1 intervention

Trial outcomes
Primary outcomes

Time frame
0, 1, 2, 4, 8, 12, and 24 hours after surgery3
Incidence of Postoperative Side Effects
Number of patients experiencing nausea, vomiting, pruritus, sedation, or hypotension after surgery.
Time frame
Up to 24 hours after surgery4
Incidence of Block-Related Complications
Number of patients experiencing hematoma, local anesthetic systemic toxicity, or infection related to the block procedure.
Time frame
