single-injection QLB(quadratus lumborum block)Procedure or surgery
Inject 0.4ml/kg 0.5% ropivacaine between quadratus lumborum and psoas major muscle
Device: The curved (C1-5) probe of Ultrasound Scanner Philips CX50 is used for scan
Drug: single dose ropivacaine 0.4ml/kg 0.5% ropivacaine is given immediately after the correct position of needle tip is verified.
Placebo ControlProcedure or surgery
Inject 0.4ml/kg saline between quadratus lumborum and psoas major muscle
Device: The curved (C1-5) probe of Ultrasound Scanner Philips CX50 is used for scan
Drug: single dose 0.4ml/kg 0.9% NS is given immediately after the correct position of the needle tip is verified
| Study group | Role | What they receive |
|---|---|---|
| single-injection QLB (quadratus lumborum block) | Experimental | Single-injection of QLB with local anesthetic is given preoperatively Receives: Procedure: single-injection QLB(quadratus lumborum block) |
| Placebo control | Placebo comparator | Single-injection of QLB with NS is given preoperatively Receives: Procedure: Placebo Control |
What is being measured
The primary outcome is the main question the study is designed to answer.
the NRS pain scores on activity 12-hours after surgery
The NRS (a number scale from 0 to 10) is a commonly used pain intensity rating tool
Measured: 12-hours after surgery
Secondary outcomes (7)
the pain scores at rest determined by the numeric rating scale (NRS, 0-10)
The NRS (a number scale from 0 to 10) is a commonly used pain intensity rating tool
Measured: At 2,4, 8, 12, 24 ,48,72 hours after the surgery
incidence of postoperative nausea and vomiting (PONV)
Measured: within 24 postoperative hours
ambulation time
Measured: within 5 days after surgery
time of recovery of bowel movement
defined as the time to first flatus
Measured: within 5 days after surgery
postoperative length of hospital stay
Measured: up to 2 weeks after surgery
patient's satisfaction of anesthesia and analgesia
use the Chinese version of Bauer questionnaire to assess the patient satisfaction of anesthesia
Measured: 48 hours after surgery
the NRS pain scores on activity after surgery
The NRS (a number scale from 0 to 10) is a commonly used pain intensity rating tool
Measured: At 2,4, 8, 24 ,48,72 hours after the surgery

Questions about this trial
What is this clinical trial studying?
A study testing single-injection QLB(quadratus lumborum block) in people with Pain Management and Nerve Block, run by Peking Union Medical College Hospital at 1 site in China.
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 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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?
the NRS pain scores on activity 12-hours after surgery (time frame: 12-hours after surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03942237, which also lists 1 linked publication.
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 2 Jan 2020.
