Summary
The serratus plane block (SPB) described by Blanco et al, 2013 is a progression from the work
with the Pecs I and II blocks. The serratus muscle is a superficial and easily identified
muscle and considered a true landmark to perform thoracic wall blocks because lateral
cutaneous branches of the intercostal nerves pierce it in the mid-axillary line. A local
anesthetic (LA) is injected under ultrasound (US) guidance either superficial or deep to
serratus anterior muscle providing predictable and relatively long-lasting regional
anesthesia, which would be suitable for surgical procedures performed on the chest wall.
The linear US probe of frequency (6-13 MHz) is placed over the mid-clavicular region in a
sagittal plane.The ribs are counted inferiorly and laterally until the fifth rib in the
midaxillary line is identified.The latissimus dorsi, teres major, and serratus muscles are
identified.
