Brief Summary
This prospective randomized clinical trial evaluates the duration of sensory blockade in patients undergoing shoulder surgery receiving interscalene brachial plexus blocks with either liposomal bupivacaine alone or liposomal bupivacaine combined with dexamethasone.

Outcome Measures
Primary Outcomes (1)
time until resolution of sensory block
Patients will be called daily until resolution of their sensory block
0-10 days
Secondary Outcomes (4)
duration of motor blockade
2, 12, 24, 36, 48, 72, and 96 hours postoperatively
pain scores (scale of 0-10)
2, 12, 24, 36, 48, 72, and 96 hours postoperatively
opioid consumption (in oral morphine equivalents)
2, 12, 24, 36, 48, 72, and 96 hours postoperatively

Study Arms (2)
Liposomal Bupivacaine Alone
ACTIVE COMPARATORParticipants receive an interscalene brachial plexus nerve block consisting of 10 mL liposomal bupivacaine (133 mg) combined with 20 mL of 0.5% bupivacaine. This regimen represents standard of care for prolonged regional analgesia in shoulder surgery.
Liposomal Bupivacaine + Dexamethasone
EXPERIMENTALParticipants receive an interscalene brachial plexus nerve block consisting of 10 mL liposomal bupivacaine (133 mg) combined with 20 mL of 0.5% bupivacaine and 6 mg preservative-free dexamethasone. This arm evaluates whether the addition of dexamethasone prolongs sensory blockade duration compared to liposomal bupivacaine alone.
Interventions
Administration of an interscalene brachial plexus nerve block using 10 mL liposomal bupivacaine (133 mg) and 20 mL of 0.5% bupivacaine for postoperative analgesia following shoulder surgery.
Eligibility Criteria
You may qualify if:
- Adults aged 18 to 80 years
- ASA physical status 1-3
- Undergoing primary shoulder surgery with interscalene nerve block
You may not qualify if:
- ASA 4 or 5
- Revision shoulder surgery
- Daily chronic opioid use (over 3 months of continuous opioid use)
- Inability to communicate pain scores or need for analgesia
- Infection at the site of block placement
- Age under 18 years old or greater than 80 years old
- Pregnant women (as determined by point-of-care serum bHCG)
- Intolerance/allergy to local anesthetics
- Weight \<50 kg
- BMI \> 40
- severe pulmonary disease including chronic obstructive pulmonary disease and restrictive lung disease
- Suspected, or known addiction to or abuse of illicit drug(s), prescription medicine(s), or alcohol within the past 2 years.
- Uncontrolled anxiety, schizophrenia, or other psychiatric disorder that, in the opinion of the investigator, may interfere with study assessments or compliance.
- Current or historical evidence of any clinically significant disease or condition that, in the opinion of the investigator, may increase the risk of surgery or complicate the subject's postoperative course.
