Brief Summary:
Video-assisted thoracoscopic surgeries (VATS) include severe postoperative acute pain which is also a predictor of chronic pain. In this study, the investigators aim to compare the postoperative effects of thoracic paravertebral block (TPVB) and intravenous patient controlled analgesia (PCA) on the prevention of chronic pain of patients undergoing VATS.

Condition or disease Intervention/treatment Phase
Pain, Postoperative Drug: Thoracic paravertebral block (TPVB) Drug: Patient Controlled Analgesia (IV PCA) Phase 4

Detailed Description:

Video-assisted thoracoscopic surgeries (VATS) include significant postoperative acute and chronic pain because of trocar site tissue damages, intercostal nerve injuries and related inflammatory responses. Poorly controlled pain in the early postoperative period usually causes chronic pain, and also affects patients' physiotherapy, mobilization and daily function.

Our hypothesis in this study is 'thoracic paravertebral block (TPVB) is associated with an improvement in control of acute and chronic pain after VATS compared to systemic analgesia.

Drug Information available for: Bupivacaine

Arm Intervention/treatment
Active Comparator: Patient Controlled Analgesia (IV PCA)
Postoperative intravenous (IV) morphine PCA is being used for acute pain control: Basal infusion: 0.3 mg/kg/h Bolus: 1 mg, Lock-out time: 20 min, 4-h limit: 10-12,5 mg
Drug: Patient Controlled Analgesia (IV PCA)
IV morphine patient controlled analgesia (PCA) is being used in the postoperative period for 48 hours. Basal infusion: 0.3 mg/kg/h, Bolus: 1 mg, Lock-out time: 20 min, 4-h limit: 10-12,5 mg
Other Name: Morphine

Active Comparator: Thoracic Paravertebral Block (TPVB)
Preoperative thoracic paravertebral block (TPVB) at 4 levels from T4 to T8 is being performed and total of 20 mL Bupivacaine 0.5% is deposited (5 mL per level by using landmark technique)
Drug: Thoracic paravertebral block (TPVB)
Thoracic paravertebral block (TPVB) is being performed by injecting 5 mL of Bupivacaine 0.5% to 4 consecutive level of paravertebral spaces between T4 and T8 by using landmark technique
Other Name: Bupivacaine
