Summary

This randomized, double-blinded, placebo-controlled trial seeks to evaluate the analgesic efficacy of the pericapsular nerve group block in the setting of outpatient hip arthroscopy.

Detailed description

The pericapsular nerve group, or PENG block, has been recently described and shows promise in providing analgesia to the hip joint. The analgesic value of this block in the setting of hip arthroscopy is unknown. This study aims to compare a preoperative PENG block to placebo block prior to outpatient hip arthroscopy under general anesthesia. The primary outcome measure is immediate postoperative pain as measured by numerical rating score in the post-anesthesia care unit (PACU). Secondary outcomes include opioid consumption, opioid-related adverse events, patient satisfaction, chronic opioid usage, and pain scores at other time points.

Conditions

• Postoperative Pain
• Hip Arthroscopy

Interventions

Type	Name	Description
PROCEDURE	Preop PENG block	Ultrasound-guided injection of 20 mL 0.5% ropivacaine according to the method described by Giron-Arango L in 2018. A needle is inserted at the inguinal level under ultrasound guidance to pass beneath the psoas tendon on top of the iliopubic eminence where the local anesthetic is injected.
PROCEDURE	Placebo block	Ultrasound-guided placebo injection of 5 mL 0.9% normal saline. Using the same landmarks as for the PENG group, a needle is inserted in the inguinal region under ultrasound guidance, whereby a subcutaneous injection of 5 mL of 0.9% saline is made.
DRUG	Ropivacaine 0.5% Injectable Solution	20 mL 0.5% ropivacaine will be injected for the preop PENG block
DRUG	Normal Saline	5 mL 0.9% Normal saline will be injected for the Placebo block
