What this trial studies

This study evaluates the effectiveness of Naldebain®, a long-acting analgesic, in combination with thoracic paravertebral block for managing postoperative pain in patients undergoing video-assisted thoracoscopic surgery (VATS). The approach aims to enhance pain control, as inadequate management of postoperative pain can lead to chronic pain and increased morbidity. Participants will receive either Naldebain or a placebo to assess the analgesic effects. The study focuses on a multimodal analgesic strategy to improve patient outcomes following surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20 to 65 who require postoperative pain relief after thoracoscopic surgery.

Not a fit: Patients with communication disorders, coagulopathy, or significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve postoperative pain management for patients undergoing thoracoscopic surgery.

How similar studies have performed: Previous studies have shown positive outcomes with multimodal analgesic strategies, suggesting potential success for this approach.
