Background:
The breast is innervated by the intercostal nerves and the brachial plexus. We propose a technique to perform breast surgery without general anesthesia using the erector spinae plane (ESP) block and selective block of four nerves that arise from the brachial plexus innervate the breast and the axilla (SBP block).
Case:
A 77-year-old man with breast cancer was scheduled for radical mastectomy and axillary clearance. He had a previous history of myocardial infarction with dilated cardiomyopathy and severely impaired ejection fraction. The surgery was performed under regional anesthesia with combined ESP and SBP block. The patient did not require opioids or other supplemental analgesics intra- or postoperatively and was discharged uneventfully.
Conclusions:
SBP is a novel block that selectively blocks branches of the brachial plexus that innervate the breast.
