Thoracic Paravertebral Block for Postoperative Analgesia After Video-assisted Thoracic Surgery.

Thoracic Paravertebral Block: a Comparative Study of Ropivacaine With Ropivacaine and Sufentanil for Treating Pain After Video-assisted Thoracic Surgery.

The use of paravertebral catheters is a recommended technique to achieve postoperative analgesia after thoracic surgery. To date there is no consensus on which drug regime (local anesthetics with or without opioid) is best. The aim of this prospective clinical trial is to determine wether the use of ropivacaine and sufentanil injected through a thoracic paravertebral catheter results in decreased acute postoperative pain compared with plain ropivacaine in patients after thoracoscopic lung surgery.

Inclusion Criteria:

• Patient scheduled for planned video-assisted thoracic surgery
• Patient that consent to participate
• Planned placement of paravertebral catheter
• Patient having a medical insurance

Exclusion Criteria:

• Patient less than 18 years
• Refusal to participate
• Known pregnancy
• Known allergies to local anesthetics, sufentanil and /or to iodinated contrast material
• Intolerance to sufentanil and/or morphine
• Chronic consumption of opiates
• Preoperative chronic pain syndrome
• Patient having a contraindication to placement of paravertebrtal catheter
