About this study

Total hip arthroplasty is currently the most effective method for treating hip joint lesions and improving quality of life, but postoperative severe pain is not conducive to rapid recovery of patients. In recent years, the widespread application of ultrasound has achieved good clinical results in iliac fascia block for postoperative analgesia in THA. However, the use of high-dose local anesthetics can increase the risk of local anesthetic poisoning, and the single block analgesia time is generally less than 24 hours. Methylene blue, as a long-acting analgesic drug, can block the pain transmission of nerve fibers for a long time, achieving analgesic effects without damaging neurons. This study used ultrasound-guided ropivacaine combined with methylene blue to perform iliac fascia block on patients undergoing total hip replacement, with the aim of prolonging pain relief time, reducing complications, and promoting postoperative recovery on the basis of traditional methods.

What is being measured

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

  1. Visual Analogue Scale(VAS)

    Use a swimming ruler about 10 cm long, marked with 10 ticks on one side, and "0" and "10" at each end. A score of 0 indicates no pain, a score of 10 indicates the most severe pain that is unbearable, and the higher the score, the greater the degree of pain

    Measured: From enrollment to 48 hours after surgery, the VAS scores at both rest and with activity (passive straight leg raise at 45°) were recorded at the following time points: before block and at 2, 6, 12, 24, and 48 h postoperatively

Secondary outcomes (9)
  1. Hypersensitive C-reactive Protein

    Hypersensitive C-reactive protein, like procalcitonin, is an inflammatory marker. Both have the same meaning and are used to reflect the postoperative analgesic effect

    Measured: From enrollment to 48 hours after surgery

  2. Procalcitonin

    Procalcitonin is an inflammatory marker, which is associated with postoperative pain, the higher the degree of pain, the higher the procalcitonin value, the lower the pain level, and the lower the procalcitonin value, and the level of procalcitonin is used to reflect the postoperative analgesic effect

    Measured: From enrollment to 48 hours after surgery

  3. Neutrophil Lymphocyte Ratio

    Measured: From enrollment to 48 hours after surgery

  4. Mean Arterial Pressure

    Measured: From entering the operating room to leaving the resuscitation room

  5. Heart Rate

    Measured: From entering the operating room to leaving the resuscitation room

  6. Duration of Surgery

    Measured: Intraoperative

  7. Number of Postoperative Salvage Analgesia

    Measured: From the end of surgery to 48 hours after surgery

  8. Walking Distance for the First Time Getting Out of Bed

    Measured: From the end of surgery to 48 hours after surgery

  9. The Number of Activities of Getting Out of Bed 48 Hours After Surgery

    Measured: From the end of surgery to 48 hours after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Ropivacaine combined with methylene blue for iliac fascia block in people with Femoral Neck Disease, run by Wang wanxia at 1 site in China.

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 5 inclusion and 9 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 4 Feb 2025. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Feb 2025). 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?

Visual Analogue Scale(VAS) (time frame: From enrollment to 48 hours after surgery, the VAS scores at both rest and with activity (passive straight leg raise at 45°) were recorded at the following time points: before block and at 2, 6, 12, 24, and 48 h 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 NCT06284941, which also lists 1 linked publication.

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 4 Feb 2025.
