[Challenges in the management of analgesia and sedation in critically ill patients with COVID-19 in Chile].

Approximately 5% of COVID-19 patients will have a severe disease requiring invasive or non-invasive mechanical ventilation. In this conditions, sedatives and analgesics are fundamental to promote tolerance, comfort and synchrony with the mechanical ventilator. High and unusual requirements for sedation, analgesics and neuromuscular blockers have been reported in these patients, contributing to prolonged exposure, a high rate of delirium and prolongation of mechanical ventilation.
