Why it mattersPostoperative pain after sternotomy and chest drains is often poorly controlled by anatomically limited blocks. SPSIPB's broader C3-T10 spread may provide more complete analgesia, reducing opioid use and enhancing recovery, which is relevant for cardiac anesthesiologists and pain specialists managing perioperative care.
