|
| E.1.1.1 | Medical condition in easily understood language |
| pain after surgery of the shoulder |
|
| E.1.1.2 | Therapeutic area | Analytical, Diagnostic and Therapeutic Techniques and Equipment [E] - Anesthesia and Analgesia [E03] |
| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
This study is designed to compare the level and duration of pain control of 10 mL of Exparel® (133 mg) injected after 5 mL 0.25% bupivacaine and 15 mL of 0.25% bupivacaine alone for interscalne brachial plexus block. We hypothesize that level and duration of pain control of 5 mL 0.25% bupivacaine and 10 mL of Exparel® (133 mg) will exceed that of 15 mL of bupivacaine 0.25% alone for ISBPB. Primary outcome measures are: Total opioid consumption up to 72 h post surgery Time to first pain medicine request made by the patient
|
|
| E.2.2 | Secondary objectives of the trial |
Secondary outcome measures are: Numeric rating scores for pain on 0-10 scale (NRS) Overall Benefit of Analgesia Score (OBAS) Modified Brief Pain Inventory Scale (MBPI) Onset and duration of sensory block Onset and duration of motor block Duration of postoperative care unit stay Time to discharge home Incidence of postoperative nausea or vomiting through the first postoperative week (Postoperative Nausea and Vomiting (PONV) Intensity scale) Sleep quality and duration through the first postoperative week Patient satisfaction with pain control Functionality of operated arm
