A Case Report of Sedation Strategy for a Patient With Coronavirus Disease 2019 Supported by Extracorporeal Membrane Oxygenation After Cesarean Section

Pneumonia caused by coronavirus disease 2019 (COVID-19) is a highly contagious disease. Unfortunately, research on extracorporeal membrane oxygenation (ECMO) assisted treatments for patients with COVID-19 infection is limited. In this case study, a patient who was in late pregnancy (35+2 weeks of pregnancy) and suffering from severe COVID-19 was extremely irritable during ECMO-assisted treatment after she underwent a cesarean section. Her Richmond Agitation Sedation Scale (RASS) score reached +3. Nevertheless, the patient successfully was treated with a continuous single/combined application of propofol, midazolam, dexmedetomidine, hibernation mixture, and other drugs for several days (maintaining RASS -2 to -4) and provided with anti-infection, mechanical ventilation, nutritional support, fluid balance under hemodynamic monitoring, liver support, and other organ function support treatments. ECMO-assisted sedation strategy for patients was introduced and discussed in this case to provide a certain reference for the clinical diagnosis and treatment of such patients.
