Evaluating the Efficacy of Erector Spinae Block in Routine Hip Arthroscopy

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.

Erector spinae block will be performed after general anesthesia has been induced. Patients will be unaware which arm of the study they are in.

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.

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.

Visual analogue pain score at the time of discharge from the Post Anesthesia Care Unit in which 0 equals no pain and 10 equals extreme pain

Hip disability and Osteoarthritis Outcome score at post-op visits in which 0 equals no pain and 100 equals unbearable pain

Patient Reported Outcomes measurement Information System score at post-op visits in which 0 equals no pain and 10 equals extreme pain

Hip range of motion in degrees of motion, will be examined by the operative surgeon in the office measured by flexion 0-110 degrees with 0 being no range of motion and 110 being full range of motion, internal rotation -5-25 degrees with -5 being no range of motion and -25 being full range of motion, and external rotation 0-60 degrees with 0 being no range of motion and 60 being full range of motion.

Pain scores each day for the first 4 weeks after surgery on the Visual Analog Scale in which 0 equals no pain and 10 equals unbearable pain
