About this study

Official title: Impact of Adductor Canal Block, Compared to Patient Controlled Analgesia, in the Surgical Stress Response of Patients Programmed for Traumatic Anterior Cruciate Ligament Repair

To evaluate the surgical stress response in anterior cruciate ligament repair with an adductor canal block versus patient controlled endovenous analgesia.

Read the detailed description

Preoperative, 2 hours and 24 hours stress biomarkers will be evaluated in two groups of patients, continous adductor canal block and morphine patient controlled endovenous analgesia.

Being tested
Adductor Canal Block, Morphine Patient Controlled Analgesia

What participants receive

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

  • Adductor Canal BlockProcedure or surgery

    Continous peripheral nerve block

  • Morphine Patient Controlled AnalgesiaDevice

    Also called Patient Controlled Analgesia

    Morphine Patient Controlled Analgesia Delivery System

Study groups in NCT04797546
Study groupRoleWhat they receive
Adductor Canal BlockExperimentalWith mild sedation, a continous bupivacaine 0.1% infusion catheter is placed in the adductor canal. Afterwards, patients are placed under General Anesthesia, and surgery starts. Preoperative, 2 hours and 24 hours stress biomarkers and analgesic quality will be measured.
Receives: Procedure: Adductor Canal Block
Patient Controlled Morphine AnalgesiaActive comparatorPatients are placed under General Anesthesia, and after surgery, a Morphine patient controlled analgesia delivery system is installed. Preoperative, 2 hours and 24 hours stress biomarkers and analgesic quality will be measured.
Receives: Device: Morphine Patient Controlled Analgesia

What is being measured

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

  1. Change of Blood Cortisol from baseline to 24 hours

    Blood Cortisol will be evaluated preoperatively, 2 hours and 24 hours postoperatively.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Adductor Canal Block in people with Anesthesia and Stress, Physiological, run by Pontificia Universidad Catolica de Chile at 1 site in Chile.

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 4 inclusion and 8 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: withdrawn, as of the sponsor's last update on 15 Mar 2021. 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 Chile. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 was withdrawn before enrolling participants, so there are no results.

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?

Change of Blood Cortisol from baseline to 24 hours (time frame: 24 hours). 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 NCT04797546, which also lists 11 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.

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 15 Mar 2021.
