Effect of Warmed Irrigation in Hip Arthroscopy Undergoing Hip Arthroscopy

Not Applicable

Conditions
Femoro Acetabular Impingement
Pain, Postoperative
Interventions
Procedure: Warmed Arthroscopic Fluids
Procedure: Room Temperature Arthroscopic Fluids
Registration Number
NCT03453866
Lead Sponsor
University of Colorado, Denver
Brief Summary

The purpose of this study is to determine if pre-warming of arthroscopic fluid reduces immediate post-surgical pain in hip arthroscopy patients. The investigators hypothesize there will be a significant decrease in the Visual Analog Score (VAS) measured 30 minutes post-operatively in the warmed fluid group compared to the control group. Secondary outcome measures to be collected will include VAS scores 60 minutes after surgery and on post-operative day (POD) one. Additionally, the investigators will collect post-operative temperature measured 30 and 60 minutes post-operatively as well as morphine equivalent dosing in PACU and at the two-week follow up visit.

Detailed Description

In the last two decades, hip arthroscopy for the treatment of femoral acetabular impingement has increased rapidly. Currently, over 30k hip scopes are performed annually in the United States (incidence 1.06 per 10K). Due to anatomical differences, hip arthroscopy procedures have the potential for significant fluid extravasation when compared to knee arthroscopy. A 2011 study on hip arthroscopy showed on average 9.68 liters of fluid were used for a standard hip procedure; of that 1.13 liters absorbed into the surrounding soft tissues. A recent systematic review and meta-analysis showed warming of arthroscopic fluids significantly decreased the risk of hypothermia during hip arthroscopy. Additionally, active warming has been shown to decrease the rate of surgical site infection during numerous procedures. In total knee arthroplasty patients, a forced air warming gown significantly reduced narcotic pain consumption compared to standard care. However, the benefits of active warming for decreasing post-operative pain has not been studied in hip arthroscopy patients. Specifically, the investigators were interested in the roll the pre-warming arthroscopic fluid plays in post-operative pain after hip arthroscopy. The purpose of this study is to see if pre-warming of arthroscopic fluid reduces immediate post-surgical pain and narcotic consumption in hip arthroscopy patients.

Primary Outcome Measures
NameTimeMethod
Changes in Visual Analog ScorePre-operatively, 30 and 60 minutes after completion of surgery, Post Op Days 1 and 14.

A Visual Analog Score (VAS) will be measured pre-operatively, 30 and 60 minutes after patient arrival in the post-anesthesia care unit (PACU). Additionally, VAS will be collected in the clinic on post-operative day (POD) 1 and POD 14. The visual analog scale measures subject reported pain on a scale of 0-100 with a score of 0 indicating no pain and 100 indicating the worst pain possible.

Secondary Outcome Measures
NameTimeMethod
Changes in Temperature30-60 minutes after after completion of surgery

Subject core temperature will be collected 30 and 60 minutes after arrival in PACU. The method for collection will be done via current standard of care.

Morphine Equivalent Dosage (MED)After completion of surgery and at the 2-week Post Operative Visit

Morphine equivalent dose (MED) will be calculated in PACU and at the subject's routine two-week post-operative appointment via medication reconciliation.
