About this study
Official title: Comparison of Thoracolumbar Interfascial Plane Block (TLIP-block) and Local Anesthetic Infiltration in Minimally Invasive Spine Surgery: A Randomized Controlled Trial
The goal of this clinical trial is to compare the effectiveness of the thoracolumbar interfascial plane block (TLIP block) versus local anesthetic (LA) infiltration in managing postoperative pain in minimally invasive surgery (MIS) for spine surgery.
The primary outcome was total morphine consumption. Secondary outcomes included pain scores using the the numerical verbal scale (NRS), opioid-related side effects, time of the first request for rescue analgesia, time to ambulation and hospital length of stay.
Read the detailed description
A single-center, prospective, double-blind, randomized controlled trial at Queen Savang Vadhana Memorial Hospital.
All 40 enrolled patients were randomized to receive the assigned intervention, Thoracolumbar interfascial plane group (TLIP group) and local anesthetic (LA) infiltration group (LA group).
- For TLIP group, patients will receive ultrasound-guild bilateral TLIP block with a total of 40 ml of 0.25% Bupivacaine.
- For LA group, patients will receive local anesthetic infiltration with a same drug by orthopedic surgeon.
At the end of surgery, patients were extubated and transferred to the PACU before being shifted to the orthopedic ward.
Postoperative assessments began upon admission to the PACU, designated as time zero, and continued at regular intervals in the orthopedic ward (6-, 8-, 12- and 24-hours post-surgery).

What is being measured
The primary outcome is the main question the study is designed to answer.

- Model description
- Patients will be randomized into two groups using a computer-generated block-of-four randomization sequence. The randomization sequence was generated by independent support staff and concealed using sequentially numbered opaque envelopes. The investigator allocated patients by opening the corresponding envelope to determine group assignment, either to receive the Thoracolumbar interfascial plane block (TLIP group) or the local anesthetic infiltration (LA group). Anesthesiologists, nurses in the Post Anesthesia Care Unit (PACU) and the orthopedic ward staff were blinded to the group allocations.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Total morphine consumption (time frame: 24 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2025; AzTrials last refreshed its copy on 8 Nov 2026.
