Anesthesia for cardiac surgery has traditionally utilized high-dose opioids to blunt the sympathetic response to surgery. However, recent data suggest that opioids prolong postoperative intubation, leading to increased morbidity. Given the increased risk of opioid dependency after in-hospital exposure to opioids, coupled with an increase in morbidity, regional techniques offer an adjunct for perioperative analgesia. The aim of this review is to describe conventional and emerging regional techniques for cardiac surgery. ⋯ New regional techniques for cardiac surgery may be potent perioperative analgesic adjuncts, but well-designed studies are needed to quantify the effectiveness and safety of these blocks.
