Introduction: Ultrasound-guided interscalene nerve block (ISB) is an effective method for providing analgesia in shoulder surgeries. This procedure involves the use of local anesthetics on the brachial plexus, visualized via ultrasound to enhance safety. Objective: To evaluate the complications and outcomes of ISB. Methodology: A systematic review was conducted using the Cochrane database to select relevant studies published between 2020 and 2024 following the PRISMA model. Results: The application of ISB showed a male predominance. The main complications observed include diaphragmatic paresis, Horner's syndrome, dyspnea, and persistent paresthesia. Although less frequent, nausea, vomiting, and hoarseness were also reported. Dyspnea and vocal complications, although minor, affect postoperative recovery. Conclusions: Despite its efficacy, ISB carries significant risks that require attention and adaptation, particularly proper staff training to minimize these complications.
