About this study

Official title: Double-blinded Randomised Controlled Trial (RCT) Comparing a High Ankle Block to Placebo in Patients Treated for Ankle Pathologies

The aim of the herein presented double-blinded is to compare the effectiveness of the high foot block against placebo infiltration in simple, uni- and bimalleolar ankle fractures.

Included will be all adult patients (>18a) treated surgically at our department. The standard peri-operative procedure at our clinic will no be altered but the additional high ankle block. The intraoperative opioid requirement, the Visual Analogue Scale for Pain (VAS) and the postoperative opioid requirement will be assessed and compared between the two groups

Read the detailed description

Ankle fractures were among the most common injuries of the lower extremity. Peri-operative, multimodal pain therapy is of great importance in the surgical treatment of those injuries. Whereas simple (uni- and bimalleolar) ankle fractures are covered peri-operatively by oral pain medication and Piritramid-PCA (PCA=Patient-controlled analgesia), complex, trimalleolar fractures usually receive additional regional pain catheters (femoralis blockade and ischiadicus blockade).

Regional pain catheters have the major downside of motor paresis and are therefore critically discussed. Various studies have explored new techniques for perioperative pain therapy. An established procedure in midfoot and forefoot surgery is the foot block. It can be inserted at different heights around the ankle joint. However, the effectiveness of the high foot block has not yet been investigated for ankle fractures. The aim of the herein presented double-blinded is to compare the effectiveness of the high foot block against placebo infiltration in simple, uni- and bimalleolar ankle fractures.

All patients who are operated on in our department due to a uni- or bimalleolar ankle fracture, who are over 18 years of age and have no serious pre-existing conditions or contraindications to local anaesthesia (LA) are eligible for inclusion.

The perioperative procedure does not change to the current treatment standard at the University Hospital Munich - Ludwig Maximilians University (LMU) except for randomization for high foot block or placebo. Both the anesthesia and the postoperative pain therapy correspond to the current treatment standard and are the same for both groups. The intraoperative opioid requirement, the VAS and the postoperative opioid requirement will be assessed.

The data is collected using the RedCap database (#19-177), which has already been reviewed by the ethics committee. The evaluation will be performed using SPSS 25.0 (IBM).

Study groups in NCT04292691
Study groupRoleWhat they receive
RopivacaineExperimentalA cumulative amount of approx. 40ml ropivacaine 0.5% (≙400mg (2x200mg) ropivacaine) is applied immediately before surgery. They are applied in a ring wall 10 cm cranially of the tip of the medial and lateral malleolus (N. peroneus superficialis (N. cutaneus dorsalis medius et intermedius, N. saphenus, N. suralis), as well as sonographically controlled (N. peroneus profundus and N. suralis)
Receives: Drug: 40ml of Ropivacaine 0.5% Injectable Solution
Ringer's LactatePlacebo comparatorAnalog to the Experimental Arm, but the same amount of Ringer (40ml) will be plicated instead Ropivacaine
Receives: Drug: 40ml of Ringer's Lactate

What is being measured

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

  1. Cumulative morphine milligram equivalent dose during the surgery (skin incision - recovery room)

    The morphine equivalent doses will be calculated based on the morphines given throughout the surgery: Begin anaesthesia to begin recovery room

    Cumulative morphine milligram equivalent dose during the surgery (skin incision - recovery room)

    Measured: Begin anaesthesia to begin recovery room; the time will vary between 1 and 4 hours

Secondary outcomes (3)
  1. Visual Analogue pain Scale (VAS)

    Postoperative pain measured on a 0-100 Visual Analogue pain Scale (VAS) with 0 meaning no pain and 100 most sever pain imaginable

    Measured: Will be collected at arrival at the recovery room and then 2 hours, 4 hours, 6 hours thereafter. For the further in-house duration,the VAS will be collected at 08:00 and 21:00 o'clock every day for further two days

  2. Postoperative cumulative morphine milligram equivalent dose

    The cumulative morphine milligram equivalent dose will be calculated from the Piritramid PCA. The PCA saves each application date and amount. This data will be gathered at the time, when the patient does not rely on the PCA any more. The Piritramid PCA will be only used in-house.

    Measured: The Piritramid PCA will be started in the recovery room and stay with the patient until she or he does not rely on it any more. Usually, the patients keep the PCA for the first two postoperative days.

  3. Rescue medication

    Time to first rescue medication. Rescue medication is defined as the first Piritramid application through the PCA system by the patient.

    Measured: The Piritramid-PCA is provided as long as requested by the patient during his in-house stay. We expect the patient to request rescue medication within the first 24 hours after surgery

Questions about this trial

What is this clinical trial studying?

A study testing 40ml of Ropivacaine 0.5% Injectable Solution and 40ml of Ringer's Lactate in people with Ankle Fractures and Anesthesia, Local, run by Ludwig-Maximilians - University of Munich.

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: status not confirmed, as of the sponsor's last update on 3 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

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.

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 Sebastian F Baumbach, MD (0049894400519474, sebastian.baumbach@med.uni-muenchen.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cumulative morphine milligram equivalent dose during the surgery (skin incision - recovery room) (time frame: Begin anaesthesia to begin recovery room; the time will vary between 1 and 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 3 Mar 2020.
