"Pecs II block was performed at the level of the fourth rib in the fascial plane between the minor pectoral and serratus anterior muscles, and 20 ml of 0.5% levobupivacaine solution were injected.~An ultrasound-guided ipsilateral parasternal block was performed via two separate injections of 4 ml of 0.375% levobupivacaine at the level of the 2nd and 4th intercostal space underneath the external intercostal membrane between the major pectoral and intercostal muscles close to the surface of the 2nd and 4th rib."
