Peripheral Nerve Stimulator-Guided Regional Anaesthesia for Modified Radical Mastectomy in High-Risk Patients – A Case Series

Thoracic paravertebral block (TPVB) is an effective and time-tested regional anesthesia (RA) technique of anesthesia/analgesia for breast surgeries. It can be performed by landmark guided, peripheral nerve stimulator (PNS) guided or ultrasound-guided techniques. We used PNS guided TPVB for carcinoma breast surgery in fifteen high-risk patients where general anesthesia was not feasible. All patients had undergone surgeries under standalone RA techniques and without any block-related complications. We describe 15 cases in which PNS guided TPVB and supraclavicular brachial plexus block were performed to conduct modified radical mastectomy under RA and monitored anesthesia care.
