Paravertebral block for breast cancer surgery

Area of Science:

• Anesthesiology
• Surgical Oncology
• Regional Anesthesia

Background:

• Major breast cancer surgery frequently leads to significant postoperative nausea, vomiting, and pain.
• General anesthesia presents a common approach, but regional anesthesia offers a potential alternative.
• Paravertebral blocks (PVB) are explored as a method for providing anesthesia during major breast surgery.

Purpose of the Study:

• To evaluate the initial experience and efficacy of using paravertebral blocks (PVB) for anesthesia in major breast cancer surgery.
• To assess PVB as an alternative to general anesthesia for breast cancer procedures.
• To report on patient outcomes and satisfaction with PVB for breast surgery.

Main Methods:

• A prospective study involving 25 patients undergoing various breast cancer surgeries under PVB.
• PVB were administered using bupivacaine 0.5% with epinephrine across thoracic segments (C7-T6) under monitored sedation.
• Patients were monitored for 72 hours, documenting sensory return, nausea/vomiting incidence, pain levels, and medication use.

Main Results:

• Successful PVB without supplementation was achieved in 20 out of 25 patients.
• No complications related to the paravertebral blocks were reported.
• Patients with successful blocks experienced minimal postoperative nausea, vomiting, and pain, with high satisfaction rates.

Conclusions:

• Paravertebral blocks (PVB) can be successfully implemented for a majority of breast cancer surgeries with a low incidence of side effects.
• Successful PVB anesthesia enabled direct transfer to the ambulatory care unit, bypassing the recovery room.
• Ambulatory breast cancer surgery under regional anesthesia via PVB demonstrates potential for significant cost savings in healthcare.
