NCT03816982

Brief Summary

This investigation will be a prospective, randomized trial. The study population will consist of adult patients scheduled to undergo major shoulder arthroscopy procedures with anesthesiology at the Ambulatory Services Center (Outpatient Surgery Center). Forty-six subjects will be enrolled in this study and will be randomized into one of two arms: 1) Single-injection bupivacaine HCl plus a subsequent bupivacaine CISB, 2) Single-injection bupivacaine HCl plus liposomal bupivacaine included in the same injection. These procedures will take place, using an ultrasound-guided method, approximately one hour prior to surgical procedure. Subjects will be followed for seven days to assess pain control by the Modified Brief Pain Inventory (MBPI) survey and outcome factors related to study and procedure using the American Shoulder and Elbow Surgeon Shoulder Score (ASES Shoulder Score).

Outcome Measures

Primary Outcomes (1)

  • Median pain score on POD1

    Median pain score on POD1 as measured by the MBPI Short Form

    24 hours

Secondary Outcomes (1)

  • Cumulative Area under Curve median pain score on POD1-3

    72 hours

Study Arms (2)

Bupivacaine HCl/Bupivacaine CISB

ACTIVE COMPARATOR

23 patients will be enrolled to receive a single-injection bupivacaine HCL interscalene block with bupivacaine CISB added.

Procedure: Single-injection bupivacaine HCl plus a subsequent bupivacaine CISB

Liposomal Bupivacaine Added to Interscalene Block

EXPERIMENTAL

23 patients will be enrolled to receive a single-injection bupivacaine HCl interscalene block with liposomal bupivacaine added to same injection.

Procedure: Single-injection bupivacaine HCl plus liposomal bupivacaine

Interventions

Patients in the liposomal bupivacaine with added bupivacaine HCl ISB group will be given a single injection LB ISB in the preoperative area only by faculty who are part of the regional anesthesia division. The injectate will include liposomal bupivacaine 10ml (133mg) mixed with bupivacaine HCl 0.5% 10 ml.

Liposomal Bupivacaine Added to Interscalene Block

Patients in the bupivacaine CISB group will undergo catheter placement with ultrasound guidance only by faculty who are part of the regional anesthesia division. A 20 mL single bolus ISB with 0.25% bupivacaine will be administered followed by catheter infusion of 0.125% bupivacaine at a rate of 5mL/hour postoperatively by the ON-Q pump
