Trial summary

Acute and chronic postoperative pain remains a major concern following thoracoscopic surgery. Firstly because pain constitutes a serious concern for patients after surgery, and secondarily because an ineffective control of pain may lead to postoperative morbidity, especially in lung cancer surgery.

About this study

Acute and chronic postoperative pain remains a major concern following thoracoscopic surgery. Firstly because pain constitutes a serious concern for patients after surgery, and secondarily because an ineffective control of pain may lead to postoperative morbidity, especially in lung cancer surgery.

To date, several procedures have been described but the best modality of locoregional analgesia for thoracoscopic surgery has not been assessed yet. The main objective of this study is to evaluate efficiency of several validated approaches for preoperative locoregional analgesia, comparing serratus plain block versus paravertebral block versus serratus plain block and paravertebral block for postoperative pain following thoracoscopic surgery.

To this end, the investigators will conduct an interventional prospective monocentric, double blind, compared and randomized study. Previously to thoracoscopic surgery, patients will be randomized in one of the three following arms: serratus plain block, paravertebral block or serratus plain block and paravertebral block combined.

What is being measured

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

  1. Pain Visual analog scale (VAS) score at coughing

    Visual analogue scales (VAS) are 10-cm lines anchored at the ends by words that define the bounds of various pain dimensions. The patient is asked to place a vertical mark on the scale to indicate the level of intensity of his or her pain.

    Numerical rating scales are similar to analogue scales except that numbers (e.g., 0 to 5) are entered along the scale.

    With category scales, the patient is asked to circle the word that best describes his or her condition (e.g., for pain intensity: None, Moderate, Severe, Unbearable).

    Measured: Immediately after following thoracoscopic surgery

A Phase 3 study testing Loco-regional anesthesia : serratus plane bloc (Ropivacaine 1,3 mg/mL, 40 mL) and paravertebral bloc (Ropivacaine 1,3 mg/mL, 20 mL) in people with Anesthesia, Local and Pain, Postoperative, run by Centre Hospitalier Universitaire, Amiens at 1 site in France.

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 7 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 19 Sep 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 France. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Pain Visual analog scale (VAS) score at coughing (time frame: Immediately after following thoracoscopic surgery). 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 NCT04222010, which also lists 1 linked publication.

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 19 Sep 2025.
