ReviewRegional Analgesia for Cardiac Surgery. Part 2: Peripheral Regional Analgesia for Cardiac Surgery.
The introduction of regional analgesia in the past decades have revolutionized postoperative pain management for various types of surgery, particularly orthopedic surgery. Nowadays, they are being constantly introduced into other types of surgeries including cardiac surgeries. Neuraxial and paravertebral plexus blocks for cardiac surgery are considered as deep blocks and have the risk of hematoma formation in the setting of anticoagulation associated with cardiac surgeries. ⋯ They are useful as important adjuncts for providing analgesia and are likely to be included in "Enhanced Recovery after Cardiac Surgery (ERACS)" protocols. There are several small studies and case reports that have shown efficacy of the regional blocks in reducing opioid requirements and improving patient satisfaction. This review article discusses the anatomy of various fascial plane blocks, mechanism of their efficacy, and available evidence on outcomes after cardiac surgery.
