About this study

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lumbar Plexus BlockadeProcedure or surgery

    Also called Marcaine

    The lumbar plexus block will be dosed with 30 milliliters of 0.25% bupivacaine with 1:200,000 epinephrine

  • ControlProcedure or surgery

    The control group will receive only a combined spinal-epidural.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Numeric Rating Scale (NRS) Pain at Rest (0-10) on 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.

    Measured: Day of surgery prior to discharge

Secondary outcomes (7)
  1. Readiness to Discharge From Post-Anesthesia Care Unit (PACU)

    Time to readiness for discharge from the PACU. Patients were considered ready for PACU discharge when they met the following criteria: a) Awake, alert, oriented and responsive b) Minimal pain, Numeric Rating Scale < 5/10 (0 = no pain, 10 = worst imaginable pain) (parenteral [injected] medications not required) c) Vital signs stable d) No active bleeding e) Minimal or no nausea f) Not vomiting, tolerating oral intake g) Oxygen saturation > 94% (or baseline) on room air h) Patient has urinated.

    Measured: Day of surgery prior to discharge

  2. Narcotic Pain Medication Needed

    Measured: Day of surgery prior to discharge

  3. Incidence of Nausea

    The number of participants with nausea.

    Measured: Day of surgery prior to discharge

  4. Incidence of Vomiting

    The number of participants who vomited.

    Measured: Day of surgery prior to discharge

  5. Requirement of Antiemetic Rescue

    The number of participants who needed medication to treat their nausea and vomiting.

    Measured: Day of surgery prior to discharge

  6. Patient Satisfaction

    Patient Satisfaction (0-10; 0 = very dissatisfied, 10 = very satisfied)

    Measured: First 24 hours after surgery

  7. Quality of Recovery (QoR-40) Physical Comfort Dimension

    Assessment of Physical Comfort (minimum score = 12, maximum score = 60). Higher values represent a better outcome

    Measured: First 24 hours after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Lumbar Plexus Blockade in people with Postoperative Pain, run by Hospital for Special Surgery, New York at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Jun 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Numeric Rating Scale (NRS) Pain at Rest (0-10) on Day of Surgery Prior to Discharge (time frame: Day of surgery prior to discharge). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jun 2013; AzTrials last refreshed its copy on 31 Oct 2026.
