Using liposomal bupivacaine for pain management in myomectomy surgery

Effect of Transversus Abdominal Plane Block Using Liposomal Bupivacaine Versus Standard Bupivacaine for Open Myomectomy: a Prospective Randomized Control Trial

PHASE4 · Icahn School of Medicine at Mount Sinai · NCT04272086

This study is testing whether a new form of pain relief called liposomal bupivacaine can help women having myomectomy surgery feel less pain and use fewer opioids afterward compared to the standard version.

What this trial studies

This study investigates the effectiveness of liposomal bupivacaine compared to standard bupivacaine in providing pain relief for patients undergoing open myomectomy. Patients will be randomly assigned to receive either type of local anesthetic through a transversus abdominal plane block before surgery. The primary focus is to analyze the impact on opioid consumption post-operatively, alongside secondary outcomes such as pain scores and recovery metrics. The study aims to enhance recovery protocols by optimizing pain management strategies.

Who should consider this trial

Good fit: Ideal candidates are women over 50kg who are not pregnant and are scheduled for open myomectomy.

Not a fit: Patients with a history of drug or alcohol abuse, chronic pain syndromes unrelated to myomas, or certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce opioid consumption and improve pain management for patients undergoing myomectomy.

How similar studies have performed: Other studies have shown promising results with liposomal bupivacaine in various surgical settings, suggesting potential for success in this application.
