The aim of this project is to evaluate the efficacy of preoperative erector spinae blocks in arthroscopic hip surgery. This will be a prospective randomized controlled trial.
The aim of this project is to evaluate the efficacy of preoperative erector spinae blocks in arthroscopic hip surgery. This will be a prospective randomized controlled trial. The control group will not receive a preoperative block prior to surgery, but will receive local anesthetic at the surgical site at the conclusion of the surgery. The study group will receive a preoperative block and local anesthetic. The primary outcomes will be pain levels and opioid consumption in the post-operative care unit. The secondary outcomes will be pain levels and opioid consumption post-operatively, and functional outcome measures.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control | Active Comparator | Will not receive erector spinae block. Will be administered 30 mL of 0.5% Marcaine w/ epinephrine as a local block at the surgical site at the conclusion of the procedure. |
|
| Study | Experimental | Will receive an erector spinae block prior to surgery using 30-45 mL of 0.25 bupivacaine w/ epinephrine and 5 mL of dexmedetomidine. Will be administered 30 mL of 0.5% marcaine w/ epinephrine as a local block at the surgical site at the conclusion of the procedure. |
