What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Femoral nerve block with ropivacaine or bupivacaineProcedure or surgery
| Study group | Role | What they receive |
|---|---|---|
| Femoral Nerve Blocks | Patients who receive ropivacaine or bupivacaine during femoral nerve block. Receives: Procedure: Femoral nerve block with ropivacaine or bupivacaine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Concentration of Local Anesthetic Injected for Femoral Nerve Block
Measured: length of surgery
Total mg of Local Anesthetic Injected for Femoral Nerve Block
Measured: length of surgery
Intraoperative Tylenol Administered
Amount of Tylenol administered based on if got ropivacaine or bupivacaine femeral nerve block.
Measured: length of surgery
Post-operative Opioids Administered
Amount of opioid consumption in the post operative anesthesia care unit depending on if the patient received femoral nerve block with ropivacaine or bupivacaine
Measured: in PACU (1 hr post-op)
Secondary outcomes (3)
Time to Discharge From PACU
Measured: Conclusion of surgery until admission to assigned unit or to phase, an expected average of 1 hour
Post-operative Pain Scale Using FLACC
The Face, Legs, Activity, Cry, Consolability scale or FLACC scale is a measurement used to assess pain for children between the ages of 2 months and 7 years or individuals that are unable to communicate their pain. The scale is scored in a range of 0-10 with 0 representing no pain.
Measured: 1 hour post-op
Post-operative Pain Scale Using VAS
The visual analogue scale (VAS) for pain is a validated, subjective measure where scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain."
Measured: 1 hour post-op

Questions about this trial
What is this clinical trial studying?
An observational study of Postoperative Pain, run by Giorgio Veneziano.
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 3 inclusion and 3 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 6 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.
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?
Yes. Results are posted in the registry (first posted 6 Mar 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Concentration of Local Anesthetic Injected for Femoral Nerve Block (time frame: length of surgery). The study lists 4 primary outcomes in all. 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 6 Mar 2019; AzTrials last refreshed its copy on 8 Nov 2026.
