In this study, patients receiving shoulder arthroscopy will receive an interscalene block for pain management containing either liposomal bupivacaine and standard bupivacaine or standard bupivacaine and dexamethasone. Patients will be followed up with to determine postoperative pain and block duration.

Numerical Rating Scale (NRS) Pain at Rest Over 72 Hours
NRS pain at rest averaged over the first 72 hours. NRS pain is on a scale from 0 (no pain at all) to 10 (worst pain imaginable). Patient reported pain at 24, 48, and 72 hours are averaged to produce this number. Lower score is a better outcome.
Time frame: First 72 hours pain
Numerical Rating Scale (NRS) Pain at Rest
NRS pain is on a scale from 0 (no pain at all) to 10 (worst pain imaginable) and is patient reported for pain at rest. Lower score is a better outcome.
Time frame: Postanesthesia care unit (up to 6 hours postoperative), postoperative day 1, postoperative day 2, postoperative day 3, postoperative day 4, postoperative day 7
Numerical Rating Scale (NRS) Pain With Movement
NRS pain is on a scale from 0 (no pain at all) to 10 (worst pain imaginable) and is patient reported for pain with movement. Lower score means better outcome.
Time frame: Postanesthesia care unit (up to 6 hours postoperative), postoperative day 1, postoperative day 2, postoperative day 3, postoperative day 4, postoperative day 7
Opioid Consumption
Opioid consumption, measured in oral morphine equivalents
Time frame: Postanesthesia care unit (up to 6 hours postoperative), postoperative day 1, postoperative day 2, postoperative day 3, postoperative day 4, postoperative day 7
Patient Satisfaction With Pain Management: Scale
Patient reported satisfaction on a scale of 0 (not satisfied) to 10 (complete satisfaction). This is patient opinionated and is reflective with patient contentedness with their pain management. Higher scores indicate greater satisfaction
Time frame: Postanesthesia care unit (up to 6 hours postoperative), postoperative day 1, postoperative day 2, postoperative day 3, postoperative day 4, postoperative day 7

Brief Pain Inventory Short-form
The Brief Pain Inventory (BPI) rapidly assesses the severity of pain and its impact on functioning. Higher scores indicate more pain. The minimum value is 0, the maximum value is 10. A lower score is a better outcome. This score is an average of the following measures on a 0-10 scale: General activity, Mood, Walking ability, Normal work, Relations to People, Sleep Quality, and Enjoyment of life.
Time frame: Postanesthesia care unit (up to 6 hours postoperative), postoperative day 1, postoperative day 2, postoperative day 3, postoperative day 4, postoperative day 7
Duration of Analgesic Block
Patients are contacted and asked questions regarding their motor strength and sensation in their shoulder. Patients are asked "When did your pain relief from the block completely wear off?" This indicates the block duration.
Time frame: 24, 48, 72, 96 (if needed) hours postoperatively
Sensory Resolution
Patients are contacted and asked questions regarding their motor strength and sensation in their shoulder.
Time frame: 24, 48, 72, 96 (if needed) hours postoperatively
Motor Block Resolution
Patients are contacted and asked questions regarding their motor strength and sensation in their shoulder.
Time frame: 24, 48, 72, 96 (if needed) hours postoperatively
Time to Readiness for Discharge
Time to readiness for PACU discharge was evaluated every 15min using the Post Anesthetic Discharge Scoring System.
Time frame: Postanesthesia care unit (0-6 hours postoperative)
Postanesthesia Care Unit Length of Stay
Total length of PACU stay as defined by time of PACU admission to PACU discharge.
Time frame: Postanesthesia care unit (0-6 hours postoperative)
