What is being measured
The primary outcome is the main question the study is designed to answer.
total consumption of opioid (mcg/kg)
total opioid consumption at 24 hours after the end of surgery
Measured: from the end of surgery up to 24 hours later
Secondary outcomes (6)
Postoperative Pain score
Pain scores is assessed by Numerical Rating Scale, which requires the patient to rate their pain on a defined scale. For example, 0-10 where 0 is no pain and 10 is the worst pain imaginable
Measured: at 30 minutes, 1 hour, 3 hours, 6 hours, 24 hours after the end of surgery
Total consumption of non-opioid (mg/kg)
Non-opioid analgesics usage per body weight within 24 hours after surgery
Measured: within 24 hours after the end of surgery
Cold sensation
Evaluation of the distribution of lost cold sensation in the skin in the recovery room (Dermatomal distribution of the loss of cold sensation using an alcohol swab at post-anesthesia care unit, assessed by a blinded assessor in the Post Anesthesia Care Unit).
Measured: at 30 minutes after the end of surgery
The incidence of side effects of analgesic medications (percent)
Analgesic-related side effects (nausea, vomiting, constipation, pruritis, dizziness, dry mouth, somnolence, etc.) within 24 hours after surgery.
Measured: within 24 hours after the end of surgery
Satisfaction score
Patient satisfaction score (0-10 points, with 10 being very satisfied and 0 being very dissatisfied).
Measured: at 24 hours after the end of surgery
Sleep quality score
Quality of sleep on the day of operation (satisfaction score, 0-10 points, with 10 being very satisfied and 0 being very dissatisfied).
Measured: at 24 hours after the end of surgery

Questions about this trial
What is this clinical trial studying?
A study testing transversalis fascial plane block and transversus abdominis plane block in people with Postoperative Pain, Acute, run by Seoul National University Hospital at 1 site in South Korea.
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 1 inclusion and 9 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 14 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. 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 consumption of opioid (mcg/kg) (time frame: from the end of surgery up to 24 hours later). 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 14 Apr 2026; AzTrials last refreshed its copy on 8 Nov 2026.
