Currently in our hospital in every day's practice, we made an association of the serratus block and the PIF block, which allows for a complete block of both the laterals branches of intercostal nerves (with the serratus block) and of anterior branches of intercostal nerves (with the PIF block). Therefore, this association of blocks may lead to a complete analgesia of the breast, while the serratus block alone only allows for an analgesia of the lateral part of the breast.
