Study Details

Study Description

Brief Summary

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.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Serratus anterior plane block
  • Device: patient-controlled analgesia
N/A

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.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Serratus anterior plane block

Deep serratus anterior plane block

Procedure: Serratus anterior plane block
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.
Other Names:
  • Deep serratus anterior plane block
  • SPB
  • Device: patient-controlled analgesia
    Each patient controls his analgesia with an IV bolus of 2mg of morphine every 10 minutes if needed, with a maximum of 20mg every 4 hours.
    Other Names:
  • PCA morphine dehydrobenzperidol
  • Active Comparator: patient-controlled analgesia

    patient-controlled analgesia: pump containing morphine (1mg/ml) and dehydrobenzperidol (50 mcg/ml).

    Device: patient-controlled analgesia
    Each patient controls his analgesia with an IV bolus of 2mg of morphine every 10 minutes if needed, with a maximum of 20mg every 4 hours.
    Other Names:
  • PCA morphine dehydrobenzperidol
