Serratus Anterior Plane Block: Post-operative Analgesia in Video-assisted Thoracic Surgery (Serrathos)

September 6, 2017 updated by: Paul Gruson, Université Libre de Bruxelles

Serratus Anterior Plane Block: Post-operative Analgesia Technique in Video-assisted Thoracic Surgery. Efficacy Pilot Study and Population Pharmacokinetic Analysis

The objective of the study is to compare the efficacy of the Serratus Anterior Plane block (SPB) realised in its deep plane, with a multi-holed catheter in place for twenty four hours, to a standard intravenous analgesia for small videoassisted thoracic surgery interventions. The objective is also to evaluate the resorption rate of local anesthetic at this level, and make a population pharmacokinetic analysis.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this study, 20 patients will be randomly assigned to one of two groups: ten patients will have a Serratus anterior plane block (SPB), with a first ropivacaine 0,375% bolus (0,4ml/kg), followed by an infusion of ropivacaine 0,2% at a 10ml/hr rate, through a multi-holed catheter located under the serratus anterior muscle, for a duration of 24 hours. The other group will have a standard intravenous analgesia with a PCA morphine-dehydrobenzperidol pump. Anesthesia protocol will be standardized. Except the infusion of ropivacaine for the SPB, per operative anesthesia and post operative analgesia will be the same for every usual patients.

The investigators will evaluate post operative pain based on the visual analog scale, 24 hours morphine consumption, sensitivity of concerned territory. The investigators will also evaluate post operative chronic pain by assessing pain two months post operatively, completing two questionnaires of neuropathic pain: DN4 and QDSA short form.

Finally, ropivacaine blood concentrations will be dosed by multiple blood samples taken over 24 hours after realizing the SPB, in order to make a population pharmacokinetic analysis, and evaluate the degree of ropivacaine resorption at this level.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

SPB realized under ultrasound guidance. Infiltration of local anesthetic (bolus then infusion through a multi-holed catheter) is realized under the serratus anterior muscle at a level situated around the 5th to 6th intercostal space on the anterior axillary lign, in order to anesthetize the cutaneous lateral branches of the intercostal nerves, with a first ropivacaine 0,375% bolus (0,4ml/kg), followed by an infusion of ropivacaine 0,2% at a 10ml/hr rate, through a multi-holed catheter, for a duration of 24 hours.
