Comparison of single-injection ultrasound-guided approach versus multilevel landmark-based approach for thoracic paravertebral blockade for breast tumor resection: a retrospective analysis at a tertiary care teaching institution

Abstract

This study compared the ALG approach with the USG approach for patients undergoing mastectomy for breast cancer. Based on our observations, an attending physician is more likely to take over an ALG injection, and more local anesthetic is administered during USG single injection.
