Comparing two doses of local anesthetics for breast cancer surgery anesthesia

Ultrasound-guided Subpectoral Plexus Block With Multi-level Thoracic Paravertebral Block for Surgical Anaesthesia During Primary Breast Cancer Surgery: A Prospective Randomized Double-blind Trial

NA · Chinese University of Hong Kong · NCT04933266

This study is testing whether using a higher dose of local anesthetic can help women having breast cancer surgery feel less pain and recover better.

What this trial studies

This study aims to compare the effectiveness of two different doses of local anesthetics (10ml vs 20ml of 0.25% levobupivacaine) for subpectoral plexus block in conjunction with ultrasound-guided multi-level thoracic paravertebral block for surgical anesthesia during major primary breast cancer surgeries. The research focuses on improving postoperative pain management and reducing the need for rescue analgesia by targeting a broader range of pain signals. By evaluating the effectiveness of these two doses, the study seeks to optimize anesthesia protocols for breast cancer surgeries, which are often performed under general anesthesia. The goal is to enhance patient recovery and minimize complications associated with postoperative pain.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for mastectomy, modified radical mastectomy, or breast-conserving surgery with lymph node biopsy.

Not a fit: Patients with local skin site infections, coagulopathy, or allergies to local anesthetics may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve pain management and recovery outcomes for patients undergoing breast cancer surgery.

How similar studies have performed: While regional anesthesia techniques have been explored in breast cancer surgeries, this specific combination of subpectoral plexus block and multi-level thoracic paravertebral block with varying doses is relatively novel and has not been extensively tested.
