COVID‐19 may lead to a sharp decline in blood oxygen, can cause sudden changes in the fetal intrauterine environment, and could possibly result in neonatal death.
The novel coronavirus (COVID-19) has become a global pandemic outbreak. Patients with COVID-19 are prone to progress to acute respiratory distress syndrome (ARDS), and even severe ARDS with ineffective mechanical ventilation, and an extremely high mortality. Extracorporeal membrane oxygenation (ECMO) provides effective respiratory support and saves time for the treatment of severe COVID-19. The present study reports that a 31-year-old pregnant female infected by COVID-19, who suffered from fever, dyspnea, and rapid ARDS. The patient's pulmonary function gradually recovered by combining early mechanical ventilation and ECMO, and finally, this patient was successfully weaned from ECMO and the ventilator. No fibrosis lesions were found in the chest CT, and the patient recovered very well after leaving from the hospital for one month.
The recirculation of venovenous extracorporeal membrane oxygenation (VV-ECMO) will decrease the efficiency of respiratory support. We report a patient with refractory severe acute respiratory distress syndrome (ARDS). Even with the support of ECMO and mechanical ventilation (MV), it is still difficult to correct hypoxemia. In this case, we placed a balloon catheter above the ECMO drainage cannula in inferior vena cava (IVC), and then occlusion the IVC with the water-filled balloon. After the occlusion, the patient’s hypoxemia was quickly improved, and angiography proved that the recirculation has been significantly reduced. In this case, IVC occlusion technology greatly reduces recirculation. Its advantages lie in simple operation, low cost, short term safety, which probably act as an innovative method to reduce recirculation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
