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

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03244631

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

Condition or disease Intervention/treatment Phase
Nerve Block Hip Arthroscopy Procedure: Lumbar Plexus BLock Procedure: Pericapsular injection Not Applicable

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 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

Primary Outcome Measures :
  1. Pain score [ Time Frame: 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 :
  1. Morphine equivalents [ Time Frame: 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

  2. Time spent in PACU [ Time Frame: Immediately after surgery ]
    Compare the overall time spent in the PACU as defined by time to arrival to time to discharge vitals.
