A breast biopsy is the surgical removal of breast tissue for histopathological analysis, usually in the setting of suspicious findings discovered on mammography or ultrasonography. This procedure can take many forms, including fine-needle aspiration cytology (FNA), core needle biopsy, open breast biopsy, excisional biopsy, and lumpectomy, and may be associated with sentinel lymph node biopsy.

Labs and studies

• Only as indicated from H&P

Patient preparation and premedication

• Can be a high-anxiety procedure, consider midazolam
• Consider scopolamine patch in young women at high risk for PONV

Intraoperative management

Monitoring and access

• Standard ASA monitors
• 18-20G PIV x 1

Induction and airway management

• Natural airway for procedures that can be done under local +/- sedation including FNA, core needle biospy
• LMA vs. ETT for deeper lesions, resections, and sentinel node biopsies

Positioning

• Supine with ipsilateral arm abducted
• Table may be airplaned to center breast

Maintenance and surgical considerations

• Standard maintenance, muscle relaxants often not required

Emergence

• No special considerations

Postoperative management

Disposition

• PACU > home

Pain management

• Pain score 2-5
• PO analgesics

Potential complications

• Hematoma formation
• Infection
• Seeding of tumor to other sites
