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

Prospective, Single Blind Randomzied Controlled Trial Comparing Lumbar Plexus Peripheral Nerve Block Versus Peri-capsular Injection for Hip Arthroscopy

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

Study Overview

• Status: Completed
• Conditions: Nerve Block; Hip Arthroscopy
• Intervention / Treatment: Procedure: Lumbar Plexus BLock; Procedure: Pericapsular injection

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: 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.	Procedure: Lumbar Plexus BLock; Peripheral nerve block
Active Comparator: 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.	Procedure: Pericapsular injection; Injection around the area undergoing surgery

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain score	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).	At the one hour point in the PACU

Secondary Outcome Measures

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