Fascial Plane Blocks: Imaging and Block Selection

Anesthesiology

Fascial plane blocks are increasingly used in regional anaesthesia to provide targeted postoperative analgesia and reduce opioid requirements. Successful application depends on understanding sonoanatomy, identifying the correct fascial layers and selecting an appropriate block according to the surgical site and expected pain distribution. Ultrasound guidance helps visualise anatomical structures, needle position and local anaesthetic spread. Techniques such as transversus abdominis plane (TAP), erector spinae plane (ESP), serratus anterior plane (SAP) and pericapsular nerve group (PENG) blocks have specific clinical applications. Understanding their indications, limitations and potential complications supports appropriate block selection and effective multimodal pain management.
