A novel experience of ultrasound-guided erector spinae plane block with sedation in breast cancer surgery: A case report

Abstract

We report the anaesthetic management of a breast cancer patient, at a high risk for undergoing general anaesthesia, using a single-shot ultrasound-guided Erector Spinae Plane Block (ESPB) with monitored sedation. Targetted at T4, 20 mL of 0.375% bupivacaine provided complete surgical anaesthesia in 15 minutes. Concurrent sedation was administered with targetcontrolled infusion of propofol with entropy monitoring throughout the procedure. The surgery lasted 90 minutes and the patient remained pain free and haemodynamically stable throughout. At the end of the surgery, the patient received 1 g of paracetamol intravenously, and did not require any further analgesics other than routinely administered paracetamol until her discharge from the hospital. On top of the successful execution of our plan, this case was especially interesting as her postoperative analgesia remained completely opioid-free.
