Perioperative and anesthetic considerations for post-acute sequelae of COVID (PASC)/long COVID.

Abstract

Post-acute sequelae of COVID (PASC), commonly known as long COVID, presents with a broad spectrum of medical conditions and symptoms persisting beyond 3 months post-SARS-CoV-2 infection, affecting over 18 million Americans and 65 million people worldwide. Despite its prevalence, to date, there are no specific clinical guidelines for the perioperative management of PASC patients. PASC is a complex, multisystemic condition leading to neurological, respiratory, and endocrine sequelae, potentially resulting from persistent viral presence, immune dysregulation, and/or end-organ damage. This manuscript discusses the implications of these sequelae on anesthesia practice, emphasizing the need for vigilance in pre-operative assessments to identify PASC and associated conditions through detailed patient history, understanding of off-label medication use, and familiarity with medical terminologies like POTS, MCAS, and brain fog. Key perioperative considerations include cautious use of anesthetics, especially in patients with neurological and cardiovascular complications. Pulmonary management strategies for PASC patients, such as lung-protective ventilation and non-invasive post-operative support, could mitigate any perioperative respiratory complications. Finally, we underscore the importance of a multidisciplinary approach to manage PASC patients effectively during surgery, advocating for personalized anesthetic plans and calling for more evidence-driven guidelines for this emerging patient group as research progresses.
