[Diagnosis and treatment of COVID-19 in intensive care units]. / Diagnostik und Therapie von COVID-19 auf der Intensivstation.

Treatment of coronavirus disease 2019 (COVID-19) is particularly challenging due to the rapid scientific advances and the often significant hypoxemia. Use of high-flow oxygen, noninvasive mask ventilation, and the technique of awake proning can sometimes avoid the need for intubation. Mechanical ventilation follows the principles of ventilation for acute respiratory distress syndrome (ARDS; lung protective ventilation) and is generally supplemented by consequent positioning therapy (with at least 16 h in prone position in multiple cycles). Antiviral therapy options such as remdesivir usually come too late for patients with COVID-19 in the ICU, the only exception being the administration of monoclonal antibodies for patients without seroconversion. The value of immunomodulatory therapy such as dexamethasone is undisputed. Interleukin­6 antagonists, on the other hand, are rather problematic for ICU patients, and for Janus kinase inhibitors, data and experience are still insufficient in this context.
