In critically ill COVID-19 patients, proper management of sedation is an important issue. Therefore, for this purpose, several strategies and protocols have been proposed. In this paper, we illustrate an approach focused on lung damage, and both the pharmacokinetic and pharmacodynamic profiles of drugs used. In line with this, during high flow nasal (HFN), continuous positive airway pressure, or non-invasive ventilation, dexmedetomidine-based light sedation can be helpful for maintaining the respiratory driving and improving the patient comfort. A worsening in the respiratory clinical picture with mechanical ventilation may require deep sedation with the use of clonidine. The latter may reduce the hypnotic doses, allowing improved hemodynamic stability. When respiratory performance improves, dexmedetomidine can replace clonidine to reduce the time to extubation.
