About this study

Official title: Acute and Chronic Pain After One-stage Hybrid Arrhythmia Ablation Surgery: A Study on the Presence of Chronic Pain After Hybrid Ablation and Factors That May be Associated

After one-stage hybrid arrhythmia ablation surgery there are possible side effects like acute and chronic pain. There is a lot of research surrounding these pains but not specifically after one-stage hybrid arrhythmia ablation surgery. The investigators want to research factors that may be associated with the absence of chronic pain after hybrid ablation include ketamine, peroperative opioids, loco-regional blocks, neuraxial blocks, wound infiltration, postoperative patient-controlled analgesia. The presence of corticosteroids or NSAIDS, will also be evaluated. Furthermore, non-adaptable factors such as genetics complicate the onset of chronic post-operative pain. Taking existing knowledge in this field into account, incidence risk as well as acute pain duration and intensity and their effects on chronic pain will become the primary focus of this study.

The investigators will contact all patients who had a one-stage hybrid arrhythmia ablation surgery at UZ Brussels. Participants will be sent a questionnaire with a consent form in and a survey asking about their pain 3 months postop and their current pain management therapy.

What is being measured

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

  1. Number of patients with acute pain after one stage hybrid ablation.

    How many patients have acute pain after surgery

    Measured: 3 months postop

  2. Number of patients with chronic pain after one stage hybrid ablation.

    How many patients have acute pain after surgery

    Measured: 3 months postop

Secondary outcomes (6)
  1. Intensity of immediate pain following one stage hybrid ablation

    How painful on a numeric pain scale rating of 0 to 10 is the immediate pain post operation? 10 being the worst pain ever felt and 0 being totally painfree.

    Measured: 3 days

  2. Duration of immediate pain following one stage hybrid ablation

    How long does the immediate pain post operation last?

    Measured: 3 days

  3. Intensity of acute and chronic pain after receiving an advance anesthesiologic pain block.

    How painful on a numeric pain scale rating of 0 to 10 is the acute or chronic pain post operation? 10 being the worst pain ever felt and 0 being totally pain free.

    Measured: 3 months

  4. Intensity of acute and chronic pain after administration of ketamine.

    How painful on a numeric pain scale rating of 0 to 10 is the acute or chronic pain post operation? 10 being the worst pain ever felt and 0 being totally pain free.

    Measured: 3 months

  5. Intensity of acute and chronic pain after treatment with opioids.

    How painful on a numeric pain scale rating of 0 to 10 is the acute or chronic pain post operation? 10 being the worst pain ever felt and 0 being totally pain free.

    Measured: 3 months

  6. Intensity of acute and chronic pain after placing of a thorax drain post operatively.

    How painful on a numeric pain scale rating of 0 to 10 is the acute or chronic pain post operation? 10 being the worst pain ever felt and 0 being totally pain free.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Questionnaire in people with Arrythmia and Chronic Pain, run by Universitair Ziekenhuis Brussel at 1 site in Belgium.

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 6 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: stopped early, as of the sponsor's last update on 18 Dec 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 Belgium. 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.

Are results available for this study?

The study was stopped early (reason given: not enough patients were recruited). Results are not available in the source record.

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?

Number of patients with acute pain after one stage hybrid ablation. (time frame: 3 months postop). The study lists 2 primary outcomes in all. 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 18 Dec 2025.
