The COVID-19 pandemic has left lasting health consequences that extend beyond the acute infection phase, with long COVID emerging as a complex multisystem condition that poses significant challenges in the perioperative setting. Patients with post-infectious respiratory or cardiovascular sequelae present an increased anesthetic risk due to persistent inflammation, pulmonary fibrosis, reduced lung compliance, and myocardial dysfunction. These alterations predispose to hypoxemia, arrhythmias, and hemodynamic instability during surgery, making preoperative assessment and individualized anesthetic planning essential. Comprehensive evaluation, including functional tests, cardiac and pulmonary imaging, and laboratory analysis, allows early identification of residual organ dysfunction that can compromise perioperative safety. Anesthetic management must be adapted to the patient's physiological condition, emphasizing lung-protective ventilation, cautious fluid therapy, and close hemodynamic monitoring. Regional anesthesia is preferred when feasible to minimize airway manipulation and reduce respiratory complications, while total intravenous anesthesia represents a safer option when general anesthesia is required. Postoperative care focuses on extended respiratory monitoring, multimodal analgesia to limit opioid use, and the implementation of pulmonary physiotherapy and antithrombotic prophylaxis to prevent complications. Psychological support is also recommended to address post-COVID anxiety and fatigue, contributing to holistic recovery. Although clinical guidelines provide useful recommendations, current evidence remains limited and heterogeneous. Further research is required to clarify the pathophysiological mechanisms of long COVID, evaluate anesthetic drug interactions, and develop validated risk stratification tools. Establishing standardized, evidence-based perioperative protocols is essential to improve outcomes and ensure patient safety in individuals with long COVID undergoing emergency surgery.
