Plain English summary of protocol
Background and study aims
A thoracotomy is a surgery to open the chest. Post-thoracotomy pain can lead to a high incidence of postoperative complications, such as pneumonia and atelectasis, if not adequately controlled. Video-assisted thoracic surgery (VATS) is considered to be less painful and safer and requires a shorter hospital stay than thoracotomy. However, pain remains an issue associated with VATS, especially for the first three days after surgery.
There are numerous pain management options for VATS, including non-steroidal anti-inflammatory drugs (NSAIDs), epidural analgesia, systemic opioids, paravertebral block (PVB), patient-controlled analgesia (PCA), and surgical wound infiltration. The researchers have demonstrated that PVB, which results in lower cumulative dezocine doses and produces fewer side effects than PCA, can provide effective pain relief for patients undergoing VATS. However, TEA has been regarded as the gold standard for managing acute pain after thoracic surgery. The aim of this study is to test whether PVB has similar pain control when compared with TEA.
Who can participate?
Patients aged 18-80, without chronic pain (with no pain medications routinely used), could provide consent to participate and precisely complete a pain assessment, and have resectable solitary pulmonary nodules.
What does the study involve?
Participants are randomly allocated into one of two groups. Participants in the first group undergo single intercostal VATS and afterwards receive patient-controlled PVB for pain relief. Participants in the second group receive thoracic epidural analgesia for pain relief and then undergo single intercostal VATS. All participants’ pain levels are assessed, and the number of patients who require extra medication on the three days after the operation is recorded.
What are the possible benefits and risks of participating?
Effective analgesia and fewer side effects are possible benefits. Postoperative analgesic failure is a possible risk.

| Scientific title | A randomized clinical trial to assess the efficacy of patient-controlled paravertebral block versus thoracic epidural analgesia for patients undergoing single intercostal video-assisted thoracic surgery |
| Study objectives | It has been demonstrated that paravertebral block, which resulted in lower cumulative dezocine doses and produced fewer side effects than intravenous patient-controlled analgesia, can provide effective pain relief for patients undergoing video-assisted thoracic surgery. However, epidural analgesia has been regarded as the gold standard for managing acute pain after thoracic surgery. This randomized study was designed to test whether paravertebral block has similar pain control when compared with epidural analgesia. |

| Health condition(s) or problem(s) studied | Pain in the postoperative period |
| Intervention | Patients were randomly allocated by a computer-generated random number list to receive patient-controlled PVB (PVB group) or thoracic epidural analgesia (TEA group) for postoperative analgesia before being transferred to the operating room. 1. In the PVB group, patients receive single intercostal video-assisted thoracic surgery and patient-controlled paravertebral block for postoperative analgesia. 2. In the TEA group, patients receive thoracic epidural analgesia for postoperative analgesia and single intercostal video-assisted thoracic surgery In the case of analgesic failure, intramuscular dezocine 10 mg (Jiangsu, China) was used as rescue medication. The chest tube was removed when there was no air leakage and the volume of drainage was less than 100 mL/24 hours. The criteria for hospital discharge included chest tube removal, adequate oral intake, pain controlled by oral analgesics and assessment of patients’ well-being by their attending doctors. |
