About this study

Official title: Effect of Bupivacaine Liposomes or Bupivacaine for Femoral Triangle or Adductor Block on Analgesia After Total Knee Replacement: a Prospective, Single-center, Simple Randomized, Active-controlled, Single-blind, 2x2 Factorial Design Clinical Study

The purpose of this study was to investigate the effect of bupivacaine liposomes on postoperative pain in TKA ( total knee replacement ) patients.The main questions answered are:

  1. Is bupivacaine liposomes superior to bupivacaine in femoral triangle block or adductor block in terms of 72 hours opioid consumption after knee replacement
  2. Which block method(Femoral triangle block or adductor block) combined with bupivacaine liposome was more effective in alleviating pain score and 72 hours opioid consumption after total knee surgery. investigators will investigate the effect of bupivacaine liposomes combined with bupivacaine and pure bupivacaine on pain after total knee arthroplasty using femoral triangle block or adductor block.

Participants will:

  1. Receive liposomal bupivacaine or bupivacaine as a regional anesthetic for femoral triangle block or adductor block under ultrasound guidance.
  2. Undergo total knee replacement surgery under spinal anesthesia.
  3. Follow-up within 72 hours after surgery , opioid consumption, NRS score, PCA(Patient controlled analgesia,PCA) data, first postoperative remedial analgesia time, quadriceps muscle strength and complications were recorded

What is being measured

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

  1. Opioid consumption 72 hours after surgery

    This primary outcome entails tracking and assessing the total opioid consumption by participants following total knee replacement surgery. The evaluation includes quantifying the amount of opioids prescribed and consumed by participants for pain management post-surgery. Opioid medications administered will be converted to morphine equivalents based on established conversion ratios. By analyzing overall opioid consumption, the study aims to evaluate the efficacy of the interventions in managing postoperative pain.

    Measured: this outcome will be monitored and recorded within 72 hours postoperatively

Secondary outcomes (4)
  1. Pain intensity

    Pain intensity will be assessed using the Numerical Rating Scale (NRS), a 0-10 scale where 0 represents no pain and 10 represents the worst imaginable pain

    Measured: Pain intensity will be measured at 8 time points: 6 hours, 12 hours, 18 hours and 24 hours 36 hours, 48 hours, 60 hours, 72 hours post-surgery

  2. Time to First Rescue Analgesic

    Time to first rescue analgesic will be recorded as the interval from the end of the surgery to the administration of the first dose of rescue analgesic medication postoperatively.

    Measured: 72 hours after surgery

  3. Total opioid dosage and PCA times

    The evaluation includes quantifying the amount of opioids prescribed and consumed PCA times by participants for pain management post-surgery.

    Measured: Total opioid dosage and PCA times were recorded at 8 time points: 6 hours, 12 hours, 18 hours and 24 hours 36 hours, 48 hours, 60 hours, 72 hours post-surgery

  4. Quadriceps muscle strength

    The quadriceps muscle strength is measured with a hand-held dynamometer

    Measured: 24.48,72 hours after surgery

Model description
This study utilizes a factorial interventional design, where participants undergoing total knee arthroplasty surgery will be allocated into four separate groups. Group one will receive liposomal bupivacaine plus bupivacaine as a regional anesthetic for adductor block, the group two will receive bupivacaine for adductor block; the group three will receive liposomal bupivacaine plus bupivacaine as a regional anesthetic for femoral nerve block ; Group four will receive bupivacaine as a regional anesthetic for femoral nerve block .Two types of interventions are involved, namely, choice of anesthesia mode (2 levels: adductor block, femoral triangle block) and anesthetic administration (2 levels: bupivacaine liposomes and bupivacaine mixture, bupivacaine).The study aims to compare the analgesic efficacy, duration of pain relief, opioid consumption, between the four groups .

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: status not confirmed, as of the sponsor's last update on 24 Oct 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 China. 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. 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?

Results are not available in the source record.

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

Contact Llingli deng, postgraduate (+86 18707159290, 296890303@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Opioid consumption 72 hours after surgery (time frame: this outcome will be monitored and recorded within 72 hours postoperatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06653621, which also lists 2 linked publications.

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.
