RESUMEN
Hantaviruses, members of the Bunyaviridae family, can cause two patterns of disease in humans, hantavirus hemorrhagic fever with renal syndrome (HFRS) and cardiopulmonary syndrome (HCPS), being the latter hegemonic on the American continent. Andesvirus is one of the strains that can cause HCPS and is endemic in Chile. Its transmission occurs through direct or indirect contact with infected rodents' urine, saliva, or feces and inhalation of aerosol particles containing the virus. HCPS rapidly evolves into acute but reversible multiorgan dysfunction. The hemodynamic pattern of HCPS is not identical to that of cardiogenic or septic shock, being characterized by hypovolemia, systolic dysfunction, and pulmonary edema secondary to increased permeability. Given the lack of specific effective therapies to treat this viral infection, the focus of treatment lies in the timely provision of intensive care, specifically hemodynamic and respiratory support, which often requires veno-arterial extracorporeal membrane oxygenation (VA-ECMO). This narrative review aims to provide insights into specific ICU management of HCPS based on the available evidence and gathered experience in Chile and South America including perspectives of pathophysiology, organ dysfunction kinetics, timely life support provision, safe patient transportation, and key challenges for the future.
