Pain Control in Hip Arthroscopy: Comparing Lumbar Plexus Versus Peri-capsular Injection

Not Applicable

Completed

• Conditions: Hip Arthroscopy; Nerve Block
• Interventions: Procedure: Lumbar Plexus BLock; Procedure: Pericapsular injection

• Registration Number: NCT03244631
• Lead Sponsor: Washington Orthopaedics and Sports Medicine

Brief Summary

Comparison of lumbar plexus nerve block versus pericapsular injection for pain control during hip arthroscopy

Detailed Description

The purpose of this study is to compare two different methods of pain control during and after hip arthroscopy surgery. It is not clear which of many different pain control methods are ideal to reduce pain for patients; consequently, the investigators are performing this study to compare the two main choices for pain control commonly used in order to identify if either is superior to the other.

Arm && Interventions

Group	Intervention	Description
Lumbar Plexus Block	Lumbar Plexus BLock	A lumbar plexus 'nerve block' is a procedure in which local anesthetic ("numbing medicine") is injected around a specific group of nerves to provide pain relief directly to the nerves supplying the area of the body undergoing surgery.
Pericapsular Injection	Pericapsular injection	The pericapsular injection is a procedure in which local anesthetic ("numbing medicine") is injected around the hip joint to provide direct pain relief to the area undergoing surgery.

Primary Outcome Measures

Name	Time	Method
Pain score	At the one hour point in the PACU	Compare post-operative pain scores in the immediate post-operative period as defined by visual-analog pain scale at the time point of one hour spent in the post-anesthesia care unit (PACU).

Secondary Outcome Measures

Name	Time	Method
Time spent in PACU	Immediately after surgery	Compare the overall time spent in the PACU as defined by time to arrival to time to discharge vitals.
Morphine equivalents	At the two hour point in the PACU	Compare the total morphine equivalents of opioids provided in the PACU within the first two hours of time spent in the PACU
