Trial summary

Total hip arthroplasty (THA) is one of the most common surgical procedures performed in elderly patients, with its main indication being end-stage osteoarthritis of the hip1. It is estimated that over 572,000 patients per year will undergo THA in the USA alone by 20301 and postsurgical pain associated with THA remains… Read more about this study

About this study

Official title: Prospective Randomized Study Comparing Suprainguinal Fascia Iliaca Block vs. Pericapsular Nerve Group Block vs. Local Anesthetic Infiltration vs. Spinal Anesthetic Without Adjuncts for Pain Control Following Total Hip Arthroplasty

Total hip arthroplasty (THA) is one of the most common surgical procedures performed in elderly patients, with its main indication being end-stage osteoarthritis of the hip1. It is estimated that over 572,000 patients per year will undergo THA in the USA alone by 20301 and postsurgical pain associated with THA remains a significant issue. Postoperative pain is associated with delayed joint mobilization, ambulation, patient satisfaction and can often delay the patient's discharge home1.

Multimodal analgesia for the management of postoperative pain following THA is now standard of care2,3. It involves a combination of local anesthetic infiltration (LAI), peripheral nerve blocks (PNBs), analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen and/or other medications, including gabapentinoids and opioids. Using multiple analgesic modalities allows for an easier and faster recovery for THA patients and ultimately allows for reduction in postoperative narcotic use and it's associated negative side effects. Total hip arthroplasty can be performed under either general anesthesia, epidural anesthesia or most commonly under spinal anesthesia, with or without epidural morphine. The adjunctive use of LAI, pericapsular nerve group (PENG) block or suprainguinal fascia iliaca compartment block (FICB) for postoperative pain management is becoming more widespread, although evidence on their efficacy has been inconsistent4-8. As such, comparative evaluation of these adjuctive analgesic modalities is imperative to optimize postoperative pain management following THA.

Read the detailed description

Suprainguinal fascia iliaca compartment block (FICB) is a technique that involves injection of local anesthetics underneath the fascia of the iliacus muscle to block the femoral nerve, the lateral femoral cutaneous nerve and, possibly, the obturator nerve9. The pericapsular nerve group block (PENG) is a technique that involves injection of local anesthetic in the musculofascial plane between the psoas muscle and the superior pubic ramus. Evidence to date shows that FICB and PENG may be effective modalities to provide postoperative pain control following THA and could reduce opioid consumption10. The above procedures have been documented as safe and effective when performed by a qualified anesthetist but come with various risks (potential motor / sensory blocade especially) and associated cost. Alternatively, or in conjunction to the above procedures, the orthopedic surgeon can perform local anaesthetic infiltration (LAI) into the anterior pericapsular tissues. To date, no study has compared the efficacy of FICB, PENG block and LAI in a randomized study, therefore a preferred postoperative analgesic regimen has yet to be determined.

In this randomized trial, the investigators aim to evaluate postoperative pain and side effects related to pain control in patients who receive FICB versus LAI versus PENG block following THA. The investigators aim to compare these procedures between each other and assertain whether these techniques compare favourably to spinal anesthetic as a control group.

What is being measured

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

  1. Visual analog pain scale (VAS)

    The primary outcome was chosen as VAS at 4 hours post-op. The investigators debated between VAS score and narcotic consumption, as both have their limitations. VAS score, which is used as primary outcome in most similar studies1, 4-9 can be affected by narcotic consumption and vice-versa. Narcotic consumption is also variable given the need for patients to ask for the medication (with the subjective nature of pain tolerance) and requirement that nursing be available to administer it while in hospital. Some studies have attempted to circumvent these limitations by utilizing patient controlled analgesia (PCA) pumps. The researchers wanted to avoid this because it does not reflect current clinical practice. Therefore, VAS was chosen at 4 hours, a time frame where the spinal effect is likely diminished, the blocks are most effective, the need for breakthrough narcotics is low, being in line with the current literature

    Measured: At 4 hours

Secondary outcomes (1)
  1. Patient satisfaction with pain control

    Secondary outcome measures include patient satisfaction with pain control at the above mentioned time points using a four point Likert scale, the need for breakthough opioids in the first 4 hours, the number of morphine equivalents consumed for the first 48 hours post-op and length of hospital stay. Complications related to anesthesia such as motor nerve block (femoral or sciatic), any perceived peripheral sensory changes, urinary retention, post-operative nausea/vomiting or signs/symptoms of local anaesthetic toxicity will be documented.

    Measured: at 4 hours

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 3 inclusion and 11 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 16 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Visual analog pain scale (VAS) (time frame: At 4 hours). 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 16 Aug 2024.
