About this study
Official title: Liposomal Bupivacaine vs. Interscalene Nerve Block for Pain Control After Total Shoulder Arthroplasty: A Randomized Clinical Trial
This study will compare interscalene nerve block versus liposomal bupivacaine (Exparel) for pain control after total shoulder replacements. Each method will be assessed in terms of post operative pain scores, pain medication consumption, length of stay, complications (nerve injuries, hematomas, cardiac/respiratory events) and rate of readmission due to pain. The aims of this study will be achieved through a randomized controlled trial and cost-effectiveness analysis.
Read the detailed description
After the decision to proceed with shoulder replacement surgery, patients will be asked to participate in this randomized trial. Consent will be completed after explanation of each treatment group and the data to be collected. Patients will be randomized into one of the two treatment groups by simple randomization into one of two groups: Group 1 will receive interscalene nerve block and group 2 will receive liposomal bupivacaine for postoperative analgesia. Randomization will be stratified by site.
The surgeon at each site will be trained prior to enrollment on the correct way to perform Exparel injections intraoperatively. Patients in the interscalene nerve block group will be given a single shot block in the preoperative area by a fellowship-trained anesthesiologist.
The primary outcome is pain score on a visual analog scale (VAS) at 24 hours postoperatively. VAS pain scores range from 0 (no pain) to 10 (unbearable pain). Secondary outcomes are postoperative VAS pain scores at 6, 12, 18, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, and 96 hours; VAS pain score at the first postoperative visit ; intraoperative opioid consumption; postoperative opioid consumption at days 1, 2, 3, and 4; total opioid consumption at day 1 (intraoperative + postoperative day 1); duration of stay in the post-anesthesia care unit (PACU); duration of hospital stay; and VAS score for satisfaction with pain control in the hospital and at home, assessed at participants' first postoperative visit. VAS satisfaction scores range from 0 (not satisfied) to 10 (completely satisfied).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Liposomal bupivacaineDrug
Also called Exparel
Patients in this group will receive a periarticular injection containing liposomal bupivacaine during surgery. The injection will be administered by the surgeon.
Interscalene Nerve BlockDrug
Patients in this group will receive an interscalene nerve block containing the local anesthetic ropivacaine prior to surgery. The nerve block will be administered by a fellowship-trained anesthesiologist.

What is being measured
The primary outcome is the main question the study is designed to answer.
Visual Analog Scale Pain Score at 24 Hours Postoperatively
The primary outcome was pain score on a visual analog scale (VAS) at 24 hours postoperatively. VAS pain scores range from 0 (no pain) to 10 (unbearable pain).
Measured: At 24 hours after surgery
Secondary outcomes (5)
Opioid Medication Consumption in Morphine Milligram Equivalents
We analyzed intraoperative opioid consumption; postoperative opioid consumption at days 1, 2, 3, and 4; total opioid consumption at day 1 (intraoperative + postoperative day 1). This was measured in morphine milligram equivalents.
Measured: Up to 4 days postoperatively
Length of Hospital Stay
Duration of stay in hospital (hours) after shoulder replacement surgery.
Measured: At the time of discharge from hospital, Up to 4 days
Postoperative Visual Analog Scale (VAS) Pain Scores
We analyzed postoperative VAS pain scores at 6, 12, 18, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96 hours and at the first postoperative visit. VAS pain scores range from 0 (no pain) to 10 (unbearable pain).
Measured: Up to first postoperative visit, maximum 30 days
Patient Satisfaction With Pain Management
Visual Analog Scale (VAS) score for satisfaction with pain control in the hospital and at home. This was assessed at subjects' first postoperative visit.VAS satisfaction scores range from 0 (not satisfied) to 10 (completely satisfied).
Measured: At first postoperative visit, up to 30 days
Length of Stay in the Post-anesthesia Care Unit (PACU)
Duration of stay in the post-anesthesia care unit (minutes) after shoulder replacement surgery.
Measured: At the time of discharge from PACU, Up to 1 day

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 30 Mar 2020). 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?
Visual Analog Scale Pain Score at 24 Hours Postoperatively (time frame: At 24 hours after surgery). 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 30 Mar 2020; AzTrials last refreshed its copy on 8 Nov 2026.
