Evaluating the Efficacy of Erector Spinae Block in Routine Hip Arthroscopy

Not Applicable

• Conditions: Hip Disease; Postoperative Pain
• Interventions: Procedure: Erector spinae block; Procedure: Local block

• Registration Number: NCT04917510
• Lead Sponsor: Carilion Clinic

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Study	Erector spinae block	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.
Study	Local block	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.
Control	Local block	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.

Primary Outcome Measures

Name	Time	Method
Post Anesthesia Care Unit Pain	6 hours post-operatively	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
Post Anesthesia Care Unit Opioids	6 hours post-operatively	Total morphine milligram equivalents of administered in the post-operative care unit

Secondary Outcome Measures

Name	Time	Method
Hip disability and Osteoarthritis Outcome Score	1 year post-operatively	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	1 year post-operatively	Patient Reported Outcomes measurement Information System score at post-op visits in which 0 equals no pain and 10 equals extreme pain
Range Of Motion	1 year post-operatively	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.
Outpatient Opioids	4 weeks post discharge	Opioids consumed after discharge from hospital
Outpatient Visual Analog Scale scores	4 weeks post discharge	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
