Chronic post-thoracotomy pain syndrome (CPTPS) is one of the most often side effects in lung surgery. After thoracotomy, its incidence ranges from 30% to 40%. The CPTPS is defined as pain that develops after surgical intervention and lasts for at least 2 months (International Association for the Study of Pain). The mechanism of the CPTPS is a long-lasting non-curable acute surgical pain associated with surgical trauma and inflammation of chest wall, lung and pleural parenchyma. For this reason,

Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| 1. Intensity of APTPS and CPTPS between groups are measured using the Visual Analogue Scale (0 = no pain and 100 mm = worst possible pain) at 7 days, 1 and 6 months after surgery. 2. Pain is measured using the Visual Analogue Scale (0 = no pain and 100 mm = worst possible pain) at 7 days, 1 and 6 months after surgery | — |

| Measure | Time frame |
|---|---|
| 1. Frequency and intensity of the CPTPS is measured using the Visual Analogue Scale (0 = no pain and 100 mm = worst possible pain) at 6 months after surgery 2. Effectiveness of TEA, PVB, and INB in CPTPS prevention are measured using the Visual Analogue Scale (0 = no pain and 100 mm = worst possible pain) at 6 months after surgery | — |
