Clinical features and acute management of COVID-19 in adults

COVID-19 is a multisystem disease that requires holistic management. Most patients will experience mild symptoms including cough, fever and mild dyspnoea. A small proportion of patients will have severe manifestations including respiratory failure, ARDS and multiorgan failure. Extrapulmonary features are common and include gastrointestinal, thromboembolic, neurological, cardiac, renal, endocrine and dermatological manifestations. The care of COVID-19 patients requires close attention to these features. This includes respiratory support (such as supplemental oxygen, NIV and awake proning);fluid, electrolyte and nutrition management;prevention, detection and treatment of thrombotic events;management of diabetic complications;review of medications;appropriate use of antibiotics;and evidence-based use of therapeutic agents such as corticosteroids, antivirals such as remdesivir and other emerging therapies such as immunomodulating agents. Early planning for treatment escalation and decision making around the appropriateness of cardiopulmonary resuscitation are crucial as deterioration can be rapid. Prolonged symptoms occur in a minority of patients and longitudinal follow-up is required.Copyright © ERS 2021.
