What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on patients who need a type of shoulder surgery called arthroscopic shoulder surgery. The study is investigating the effects of a medication called tranexamic acid, which is given through an injection into a vein during the surgery. Tranexamic acid is being studied to see if it can help reduce pain after the surgery.

The purpose of the study is to evaluate whether using tranexamic acid can decrease the need for pain relief medications, like morphine, in the first 24 hours after surgery. During the study, some patients will receive tranexamic acid, while others will receive a different solution called sodium chloride, which is often used in medical settings as a standard fluid. This will help researchers compare the effects of tranexamic acid with those of sodium chloride.

Participants in the study will have their shoulder pain assessed at different times after the surgery, including 24 hours and 7 days later. They will also be asked about their satisfaction with the anesthesia experience and the functionality of their shoulder 30 days after the surgery. The study will also monitor any side effects that occur during the trial. The goal is to gather information that could improve pain management for patients undergoing shoulder surgery in the future.

The research process

The trial runs in 7 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Joining the study

    Upon joining the study, ensure that the informed consent form is signed. This confirms understanding of the study and agreement to participate.

    Eligibility criteria include being 18 years or older, requiring shoulder arthroscopy, and being affiliated with a social security scheme.

  2. Step 2

    Pre-surgery preparation

    Before the surgery, receive information about the procedure and the medications involved.

    The study involves the use of tranexamic acid and sodium chloride, both administered intravenously during the surgery.

  3. Step 3

    Surgery and medication administration

    During the arthroscopic shoulder surgery, tranexamic acid is injected intravenously. This is a solution for injection.

    Additionally, sodium chloride is administered as a solution for infusion.

  4. Step 4

    Post-surgery monitoring

    In the 24 hours following surgery, the use of morphine treatments is evaluated. This involves a simple yes or no assessment.

    Shoulder pain is assessed using a Visual Analog Scale, ranging from 0 to 100, 24 hours after surgery and again 7 days later through an online assessment.

  5. Step 5

    Experience and satisfaction evaluation

    Satisfaction with the general anesthesia experience is evaluated through a questionnaire.

    This helps understand the overall experience and any areas for improvement.

  6. Step 6

    Shoulder functionality assessment

    Thirty days after surgery, the functionality of the shoulder is evaluated using the Subjective Shoulder Value scale and the Constant Score.

    These assessments help determine the recovery progress and shoulder function.

  7. Step 7

    Adverse events monitoring

    Throughout the study, any adverse events are collected and monitored.

    This ensures the safety and well-being of participants during the trial.

Who can join the trial?

4 criteria

  • Must be a male or female aged 18 years old or more.
  • Must be a patient requiring shoulder arthroscopy (a type of surgery on the shoulder).

Who cannot join the trial?

3 criteria

  • Patients who do not require shoulder arthroscopy cannot participate.
  • Patients who are not within the specified age range cannot participate.
  • Patients who are part of a vulnerable population cannot participate.

Investigated drugs

  • Morphine

    is a medication used to relieve severe pain. In this clinical trial, it is being evaluated for its effectiveness in managing pain after shoulder surgery. Morphine works by changing the way the brain and nervous system respond to pain, providing relief to patients who have undergone surgery.

  • Tranexamic Acid

    is a medication used to reduce bleeding. In this trial, it is administered intravenously during shoulder surgery to help control bleeding and potentially improve recovery. Tranexamic Acid works by preventing the breakdown of blood clots, which can help reduce blood loss during and after surgery.

What is already known about the treatment

Tranexamic Acid – This medication is administered intravenously during surgery, specifically in the context of arthroscopic shoulder surgery. It is currently being studied in clinical trials to assess its effectiveness in reducing post-operative pain. Tranexamic Acid is primarily used to prevent excessive bleeding by helping blood to clot more effectively. It works by inhibiting enzymes that break down blood clots, thus stabilizing the clot and reducing bleeding. It is classified as an antifibrinolytic agent.

Investigated diseases

Shoulder Pain – Shoulder pain is a condition characterized by discomfort or pain in the shoulder area, which can result from various causes such as injury, overuse, or underlying health conditions. The pain may be acute or chronic and can affect the shoulder's range of motion and functionality. It often begins with mild discomfort and can progress to more severe pain, impacting daily activities. The condition may involve inflammation of the shoulder joint or surrounding tissues, leading to stiffness and reduced mobility. Over time, if not addressed, shoulder pain can lead to muscle weakness and decreased shoulder function.
