What this trial studies

This clinical trial investigates the effectiveness of intrathecal morphine for pain management in patients undergoing video-assisted thoracoscopic surgery (VATS). It is a randomized, placebo-controlled, double-blinded study where participants are assigned to receive either 5 mcg/kg of preservative-free intrathecal morphine or a placebo. The study aims to determine if morphine can reduce postoperative analgesic consumption and alleviate pain. Patients will be assessed for pain levels and medication use before discharge and through follow-up surveys at 1 and 3 months post-surgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-80 undergoing elective video-assisted thoracoscopic surgery for lung resection.

Not a fit: Patients with severe comorbidities, chronic pain, or those who are allergic to morphine may not benefit from this study.

Why it matters

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

How similar studies have performed: Previous studies have shown promising results with intrathecal morphine for pain management, indicating potential for success in this approach.
