The goal of this study is the evaluation of erector spinae plane (ESP) blocks as an alternative to interscalene brachial plexus nerve blocks for rotator cuff repair and total shoulder arthroplasty procedures. Currently, single shot interscalene nerve blocks are performed for rotator cuff repair surgeries, and interscalene nerve catheters are placed for total shoulder arthroplasty surgeries. Erector spinae plane blocks are commonly used as part of the anesthetic plan for other surgeries, but less so for shoulder surgeries. The investigators would like to study whether an ESP block can provide similar pain control compared to an interscalene nerve block, with less risk of upper extremity motor block and phrenic nerve block.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Interscalene nerve block | Active Comparator | Patients undergoing rotator cuff repair surgery or total shoulder arthroplasty will undergo a single shot interscalene brachial plexus nerve block or an interscalene brachial plexus nerve catheter. In the preoperative area, all participants will be asked baseline indicators of pain level via a Numeric Rating Scale (NRS, 0-10, where 0 is no pain and 10 is the worst imaginable pain) and diaphragmatic excursion will be measured bilaterally using ultrasonography before nerve block placement. Motor and sensory exams will also be performed. The same parameters will be measured 30 minutes after the block is performed. In the recovery room, those with nerve catheters will receive a dose of local anesthetic. All patients will have the same parameters measured 30 minutes postoperatively. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Interscalene brachial plexus nerve block | Procedure | An interscalene brachial plexus nerve block (single shot or catheter, depending on surgical procedure) will be placed under ultrasound guidance and all patients will receive 10cc 0.5% ropivacaine during block placement. Patients with a nerve catheter will receive a bolus of 5cc 0.5% ropivicaine postoperatively, on arrival to the recovery unit. |
| Measure | Description | Time Frame |
|---|---|---|
| Incidence of diaphragmatic paresis or paralysis | Change in diaphragmatic excursion (measured bilaterally using ultrasonography) from before block placement to 30 minutes after catheter is bolused in recovery | Before block placement, and 30 minutes after catheter is bolused in recovery |
| Pain score | Pain scores for all patients will be recorded through the first 48 hours postoperatively using the Numeric Rating scale (ranging from 0 to 10, 0 is no pain and 10 is the worst imaginable pain). | 48 hours |
| Measure | Description | Time Frame |
|---|---|---|
| Brachial plexus sensory exam change | Brachial plexus sensory exam change: dichotomous measurement (yes or no) for change in sensation over C5-C8 dermatomes | Before block placement, and 30 minutes after catheter is bolused in recovery |
| Brachial plexus motor exam change |
