About this study
The purpose of this study is to determine which medication(s) should be included in the interscalene nerve block (an injection of local anesthetic [numbing medicine] near nerves in the shoulder) for patients undergoing total shoulder arthroplasty (shoulder replacement). The ideal nerve block would reduce pain after shoulder surgery without causing a great deal of muscle weakness.
Read the detailed description
All patients will receive an intravenous pain pump (patient-controlled analgesia) and a nerve block with long-lasting local anesthetic. The three study groups will receive additives (clonidine, dexamethasone, buprenorphine plus local anesthetic) in the nerve block that may reduce postoperative pain. One of the study groups uses the usual concentration of local anesthetic, while the other two study groups use reduced concentrations of local anesthetic. Follow-up with study patients begins on the day of surgery and continues through postoperative day 2. Seen twice daily, patients will be asked about their pain and assessed for sensory function and strength of their shoulder muscle and hand grip.

What is being measured
The primary outcome is the main question the study is designed to answer.
Numeric Rating Scale (NRS) Pain Score With Movement
Pain with movement at 24 hours from the nerve block (scale of 0-10; 0 = no pain, 10 = worst possible pain)
Measured: 24 hours after the interscalene block is given
Secondary outcomes (3)
Duration of Analgesia From Interscalene Nerve Block
Median time until a patient needed to take opioid pain medication
Measured: Postoperative day 1 at 8AM & 5PM, postoperative day 2 at 8AM & 5PM
Numeric Rating Scale (NRS) Pain Scores at Rest
Assessment of NRS pain scores (scale of 0-10; 0 = no pain, 10 = worst possible pain) at rest
Measured: Preop
Middle Deltoid
A physical assessment will be done to determine the strength of the middle deltoid muscle in the operative arm using a dynamometer
Measured: 24 hours after surgery

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Interscalene Block (ISB) - 0.375% Ropivacaine + additives, Interscalene Block (ISB) - 0.2% Ropivacaine + additives and Interscalene Block (ISB) - 0.1% Ropivacaine + additives in people with Total Shoulder Arthroplasty, run by Hospital for Special Surgery, New York at 1 site in United States.
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 6 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 18 May 2016. 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 United States. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 May 2016). 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?
Numeric Rating Scale (NRS) Pain Score With Movement (time frame: 24 hours after the interscalene block is given). 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 18 May 2016.
