About this study

Official title: Efficacy of Transversus Thoracis Muscle Plane Block in Patients Undergoing Cardiac Surgery. A Randomized Controlled Trial

The goal of this randomized double blind study is to evaluate the analgesic efficacy of Transversus Thoracis Muscle Plane Block in patients undergoing cardiac surgery with median sternotomy.

one group of participants will receive multimodal analgesia plus ultrasound-guided Transversus Thoracis Muscle Plane Block with ropivacaine 0.5 % after induction of general anesthesia, the other group will receive multimodal analgesia without a bloc.

The investigators want to know if participants who receive the Transversus Thoracis Muscle Plane Block with ropivacaine have less pain than participants who do not receive a block.

Read the detailed description

Participants who undergo elective cardiac surgery with median sternotomy are eligible. They will receive general anaesthesia with multimodal analgesia as is standard in our institution. For study purposes participants will be randomized in a double blinded fashion to receive a Transversus Thoracis Muscle Plane Block with 30 mL of ropivacaine 0.5 %, or no block. As the block is carried out after induction of general anesthesia the participants will not know to which group they are assigned.

all blocks will be carried out after induction of general anesthesia, under full sterile precautions, and with ultrasound guidance. multimodal analgesia intra- and postoperatively is standardized and consists of: sufentanil, ketamine, dexmedetomidine, dexamethasone, paracetamol, metamizole, IV morphine in ICU.

The investigators aim for fast track surgery, i.e. extubation either in the operating room or in ICU within the first 6 postoperative hours.

the primary outcome is postoperative opioid consumption over the first 24 h postoperatively, secondary outcomes are pain scores and opioid-related side effects. all outcomes will be assessed by blinded investigators.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing ultrasound-guided Transversus Thoracis Muscle Plane Block in people with Postoperative Pain, run by Hôpital du Valais at 1 site in Switzerland.

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 15 Jun 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 Switzerland. 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?

opioid consumption (time frame: 24 hours postoperatively). 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 15 Jun 2025.
