Overview

Brief Summary

The purpose of this study is to determine whether the use of a lumbar plexus block for arthroscopic hip surgery is superior to oral and intravenous opioid pain medications alone in treating pain. In addition, the study will examine whether lumbar plexus blocks reduce the total amount of pain medication needed, and therefore reduce the side effects of these medicines and increase patient satisfaction. It is hypothesized that addition of the lumbar plexus block will significantly reduce patients' postoperative pain.

Outcomes

Primary Outcomes

Numeric Rating Scale (NRS) Pain at Rest (0-10) on Day of Surgery Prior to Discharge

Time Frame: Day of surgery prior to discharge

The Numeric Rating Scale was used to ask patients to rate their pain at rest on a scale of 0 to 10, 0 = no pain and 10 = worst pain imaginable.

Secondary Outcomes

Readiness to Discharge From Post-Anesthesia Care Unit (PACU)(Day of surgery prior to discharge)
Narcotic Pain Medication Needed(Day of surgery prior to discharge)
Incidence of Nausea(Day of surgery prior to discharge)
Incidence of Vomiting(Day of surgery prior to discharge)
Requirement of Antiemetic Rescue(Day of surgery prior to discharge)
Patient Satisfaction(First 24 hours after surgery)
Quality of Recovery (QoR-40) Physical Comfort Dimension(First 24 hours after surgery)
