Ultrasound guided surgery under Dilutional Local Anaesthesia and no sedation in breast cancer patients

摘要

Background: Breast cancer surgery under local anaesthesia (LA) can be challenging due to limitation of dose and quantity of anaesthetic agent that can be used safely. Elderly patients with breast cancer and with multiple co-morbidities are often prevented from having a standard treatment as they are considered unfit for general anaesthesia. We describe a technique of surgery under local anaesthesia without sedation that employs dilution to generate large volumes of LA and infiltration under ultrasound guidance.
