Serratus Plain Block Versus Paravertebral Block Versus Serratus Plain Block and Paravertebral Block for Postoperative Pain Following Thoracoscopic Surgery (thoracoscopic)

September 16, 2025 updated by: Centre Hospitalier Universitaire, Amiens

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pain Visual analog scale (VAS) score at coughing
Time Frame: Immediately after following thoracoscopic surgery

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).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
