This study is to examine the analgesic effectiveness of continuous loco-regional analgesic application (ropivacaine) through surgically placed Intercostal Catheter (ICC) and to establish correctly this method as a possible standard of care in the postoperative analgesia after Video-assisted thoracoscopic surgery (VATS) anatomical lung resection.
Good control of the pain without excessive use of opiates supports the benefits of minimally invasive surgical procedure.
This study is to examine the efficacy of continuously via surgically placed intercostal catheter administered ropivacaine at a flow rate of 6-8 ml/h of 2 mg/ml on post-operative pain (NRS) and pulmonary function (FEV1, PEF) during a maximum of 72 ± 2 hours after skin closure. Patients undergoing video-assisted thoracoscopic anatomical resection of the lung under general anaesthesia with confirmed or anticipated Stage I Lung cancer will be included. The study will be conducted as superiority, double-blind, placebo-controlled, randomized. The efficacy of loco-regional administered ropivacaine will be compared to placebo (NaCl, 0.9%) administration. The whole study period per participant is expected to be 6 months. In the follow-up, 6 months after surgery, the impact of ropivacaine on long-term pain (NRS, McGill) and pulmonary function (FEV1, PEF) shall be evaluated.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Experimental Intervention Ropivacain | Experimental | Ropivacain Fresenius 0.2% is a solution for infusion/ injection and will be continuously administered with an elastomer pump through the surgically placed intercostal catheter (ICC) between parietal pleura and fascia endo-thoracica at the level of surgical incision for a maximum of 72 hours at an initial standard flow rate setting of 6 ml/h using 2 mg/ml ropivacaine. In case pain exceeds 7 on NRS later than 2 hours after skin closure the flow rate will be adjusted on 8 ml/h. Furthermore, Ropivacain Fresenius 0.2% will be provided in a 20 ml glass vial for flushing the infusion line and subpleural administration. |
|
| Control Intervention Placebo | Placebo Comparator | Placebo (NaCl 0.9% B. Braun) is an isotonic solution for infusion and will be continuously administered with an elastomer pump through the surgically placed intercostal catheter (ICC) between parietal pleura and fascia endo-thoracica at the level of surgical incision for a maximum of 72 hours at an initial standard flow rate setting of 6 ml/h using NaCl 0.9%. In case pain exceeds 7 on NRS later than 2 hours after skin closure the flow rate will be adjusted on 8 ml/h. Furthermore, NaCl 0.9% will be provided in a 20 ml glass vial for flushing the infusion line and for subpleural administration, which will be prepared by the hospital pharmacy. |

| Ropivacain | Drug | Intercostal continuous loco-regional ropivacaine (2 mg/ml) administration over an elastomeric pump through a surgically placed intercostal catheter (ICC) for a maximum of 72h. As concomitant treatments a standardized anesthesia protocol including intravenous continuous application of propofol and remifentanil is used. Additionally, i.v. metamizol at a dose of 1 g will be administered at the end of surgery as a standard, if not contraindicated. In a standardized postoperative pain protocol the use of basic oral medication is documented as part of the postoperative follow-up and consists of: ibuprofen 3 x 400 mg p. o. for 3 days, metamizol 4 x 1 g p. o. for 3 days; if ibuprofen and/or metamizol contraindicated then paracetamol p. o. 3 x 1g for 3 days will be administered; morphine 10 mg p. o. 6 times daily will be given on a patient demand basis. |

| change in Silverman integrating approach (SIA) score, combined rank-based analysis of pain score and opioid consumption. | Silverman integrating approach (SIA) score is a combined score from the pain numerical rating scale (NRS) and analgesics (opiate) usage. It is a sum of rank- based percentage differences from the mean rank in pain scores and opioid use, ranging from -200 to 200%. SIA-scores integrate pain scores and opioid use for the individual patient. | within 72 ± 2 hours postoperative |

Three pain scores are derived from the sum of the intensity rank values of the words chosen for sensory, affective and total descriptors. The SF-MPQ also includes the Present Pain Intensity (PPI) index of the standard MPQ and a 10 cm visual analogue scale (VAS), 0 = no pain to 10 = worst pain imaginable. The higher the integrated score, the higher the pain level. | before surgery, 48 hours after skin closure and 6 months ± 28 days after surgery |
