Editorial Commentary: The Evolution of Regional Anesthesia in Arthroscopic Rotator Cuff Repair: From Throbbing Shoulders to Paralyzed Diaphragms

摘要

? 2021 Arthroscopy Association of North AmericaRotator cuff repair may result in significant postoperative pain. Although opioids were once the gold standard, addiction and other side effects are of significant concern. Nonsteroidal anti-inflammatory drugs reduce pain, sleep disturbance, and need for opioids, but they may impair soft tissue healing. The use of gabapentinoids is equivocal. Intralesional analgesia carries a risk of glenohumeral chondrolysis. Cryotherapy is beneficial, but it is often not covered by insurance companies. Suprascapular nerve block addresses innervation of only 70% versus interscalene block, but the latter has a higher incidence of unintended, temporary motor and sensory deficits of the upper extremity and hemidiaphragmatic paresis, despite similar pain scores. Although neurodeficits and diaphragmatic hemiparesis resolve by 3 weeks, temporary complications affect length of hospital stay, initiation of physical therapy, and patient satisfaction. These variables contribute to the challenge of postoperative pain control amid a growing wave of modalities aimed at improving the extent and duration of patient-focused analgesia, especially the application of continuous block infusions.
