About this study

Stimulating catheters have been introduced to reduce the incidence of secondary failure after continuous peripheral nerve blocks, but they effectiveness over traditional nonstimulating catheters is still controversial. The aim of this prospective, randomized, blinded study is to detect if stimulating catheters improve postoperative compared with conventional non-stimulating catheters.

Being tested
Continuous lumbar plexus: stimulating catheter, Spinal Anesthesia, Local anesthetic infusion, Intravenous analgesia, Opioids rescue analgesia

What participants receive

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

  • Continuous lumbar plexus: stimulating catheterProcedure or surgery

    Perinervous stimulating catheter ("Stimulong", "Pajunk", Germany) will be insert in lumbar plexus through tuohy needle (18G, 100mm length). 15ml mepivacaine 1% are injected before the complete resolution of the spinal anesthesia.

  • Spinal AnesthesiaProcedure or surgery

    Spinal anesthesia will be perform at L3-L4 or L4-L5 level. Levobupivacaine 0,5% 15mg will be injected.

  • Local anesthetic infusionProcedure or surgery

    Continuous infusion (Mini Rythmic Evolution, Micrel) of ropivacaine 0,2% at 3ml/h, bolus 3 ml, lockout time 15 min, 12 ml/h maximum dose through perinervous catheter until 3rd postoperative day

  • Intravenous analgesiaProcedure or surgery

    Ketorolac 30mg 3 times a day

  • Opioids rescue analgesiaProcedure or surgery

    Buprenorphine 0,2mg twice a day if VAS>4

  • Mepivacaine 1%Drug

Stimulating catheterExperimentalAfter Spinal Anesthesia (Levobupivacaine 0,5% 15mg) all patients in the arm will receive continuous lumbar plexus block with stimulating catheter ("Stimolong", "Pajunk", Germany). Mepivacaine 1% 15 ml will be administrated. As post-operative analgesia Ropivacaine 0,2% will be continuous administrated.

What is being measured

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

  1. Local anesthetic consumption

    Evaluation of local anesthesic consumption every 6h in first 72 postoperative hours.

    Measured: 72h

Secondary outcomes (7)
  1. Visual Analog scale (VAS) score

    Evaluation of VAS static and VAS dynamic during first 72 postoperative hours

    Measured: 72h postoperatively

  2. Up and Go test

    "up and go" test: time need to get up from a chair, walk for 3 meters, and come back to seat down on the chair

    Measured: 4th postoperative day

  3. Opioids request

    Opioids consumption will be recorded throughout 72 postoperative hours

    Measured: 72h postoperatively

  4. Quadriceps strength

    evaluate bilateral muscle strength with an isometric force dynamometer to measure the force produced during a maximum voluntary isometric contraction in a lying position by the knee flex to 90°.

    Measured: preoperative and 24h, 48h, 72h postoperatively

  5. postoperative nausea and vomiting (PONV)

    Evaluation of nausea and vomit incidence in postoperative period with scale 0 from 4

    Measured: 72h postoperatively

  6. Needle redirections

    During catheter positioning number of needle redirections necessary to found lumbar plexus are recorder.

    Measured: During catheter position

  7. Catheter insertion time

    Time (minutes) needed for catheter placement

    Measured: During catheter positioning

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Continuous lumbar plexus: stimulating catheter, Spinal Anesthesia and Local anesthetic infusion in people with Hip Replacement Arthroplasty, run by ASST Gaetano Pini-CTO at 1 site in Italy.

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 1 inclusion and 1 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 14 Aug 2017. 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 Italy. 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?

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?

Local anesthetic consumption (time frame: 72h). 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 14 Aug 2017.
