A total mastectomy (simple mastectomy) refers to the complete removal of breast tissue. A modified radical mastectomy refers to the removal of the breast and the corresponding axillary lymph nodes.
Preoperative management
Patient evaluation
| System | Considerations |
|---|---|
| Neurologic | |
| Cardiovascular | Chemotherapy (ex. anthracyclines) can cause cardiomyopathy that is often irreversible.
Use of trastuzamab can cause reversible decrease in LV function. |
| Pulmonary | Patients receiving radiation therapy to the chest/thorax can have respiratory compromise |
| Gastrointestinal | |
| Hematologic | Chemotherapy can cause anemia and thrombocytopenia. |
| Renal | |
| Endocrine | |
| Other |
Labs and studies
- CBC with diff and platelet count
- May have anemia or thrombocytopenia due to chemo
- EKG
- Consider echo
- May have cardiomyopathy due to chemotherapy
Operating room setup
Patient preparation and premedication
- Consider acetaminophen, gabapentin and/or celecoxib
- Anxiolysis, as needed
- ERAS protocol
Regional and neuraxial techniques
- Consider paravertebral blocks, transversus abdomens plane (TAP) block, or thoracic epidural
- Studies have shown a trend towards increasing utilization of peripheral nerve blocks (PNB) for mastectomy. As of 2018, ~13% of cases involved a PNB according to the National Anesthesia Clinical Outcomes Registry[1].
Intraoperative management
Monitoring and access
- PIV x 1-2 (non-operative extremity)
- Place BP cuff on non-operative extremity
Induction and airway management
- Standard induction
Positioning
- Supine
- Ipsilateral arm may be prepped into field
- Repositioning may be required
- Avoid brachial plexus stretch
- Repositioning may be required if reconstruction is also being done (i.e. latissimus doors flap)
Maintenance and surgical considerations
- Standard maintenance
- Surgeon may prefer no paralytic for the axillary direction
- Maintain normovolemia -goal-directed fluid management
- Maintain normothermia - warming blanket
- Avoid anemia and blood transfusions
- Watch out for potential pneumothorax with deep surgical exploration
Emergence
- PONV prophylaxis (females are more susceptible to PONV)
Postoperative management
Disposition
- PACU
Pain management
- Emphasize multimodal pain management
Potential complications
- PONV
- Lymphedema
- Seroma
- Pneumothorax
