Ultrasound-guided modified serratus anterior plane block for perioperative analgesia in breast oncoplastic surgery: A case series

Ultrasound-guided serratus anterior plane (SAP) block has been described to provide complete anaesthesia and analgesia to the lateral thoracic wall. Its use has been recently reported in breast reconstruction surgeries. We present a series of 11 patients where ultrasound-guided SAP block was used as part of multimodal analgesia in breast reconstruction surgery using latissimus dorsi (LD) myocutaneous flap after mastectomies. This resulted in excellent analgesia in the perioperative period and minimal use of intravenous analgesics. The SAP block technique described here is safe and also provides effective analgesia in breast reconstruction surgery with LD flap.
