Summary

Thoracic surgery is widely recognized as one of the most painful surgical procedures. Compared to open thoracotomy, video-assisted thoracoscopic surgery (VATS) offers similar therapeutic outcomes with less invasiveness, significantly reducing postoperative pain and promoting recovery. Despite the use of video-assisted thoracoscopic surgery (VATS), a significant proportion of patients still experience considerable discomfort. Specifically, 78% of patients report moderate to severe pain, with 27% experiencing moderate pain, 34% severe pain, and 17% very severe pain. Multiple studies have shown that the use of regional anesthesia, such as thoracic paravertebral nerve block (TPVB), in these surgeries can block the transmission of nociceptive signals via the intercostal nerves, producing good analgesic effects. This can reduce the consumption of postoperative opioids, decrease inflammatory responses, and improve patient survival rates after surgery. By comparing the differences in hemodynamic parameters, inflammatory stress indicators, and intraoperative and postoperative analgesic effects of thoracic paravertebral nerve block in different preoperative positions for patients undergoing thoracoscopic surgery, we aim to identify the optimal nerve block position, thereby promoting patient recovery.

• Lung Nodules
• Lung Cancer

Interventions

Type	Name	Description
BEHAVIORAL	Supine position	For patients scheduled for thoracoscopic surgery, thoracic paravertebral nerve block was performed under ultrasound guidance. After the injection of the drug, patients were positioned in either the supine position.
BEHAVIORAL	lateral decubitus position	For patients scheduled for thoracoscopic surgery, thoracic paravertebral nerve block was performed under ultrasound guidance. After the injection of the drug, patients were positioned in the lateral decubitus position with the puncture side up.
