Transesophageal Echocardiographic Assessment in Patients with Severe Respiratory Distress due to COVID-19 in the Prone Position: A Feasibility Study

Background and aim: Our aim was to assess the feasibility, safety, and utility of implementing transesophageal echocardiographic screening in patients with coronavirus disease-2019 (COVID-19)-related acute respiratory distress syndrome (ARDS), receiving mechanical ventilation (MV) and in prone position (PP).Methods: Prospective observational study performed in an intensive care unit; patients 18 years, with ARDS, invasive MV, in PP were included. A total of 87 patients were included.Results:There was no need to change ventilator settings, hemodynamic support, or any difficulties with the insertion of the ultrasonographic probe. Mean duration of transesophageal echocardiography (TEE) was 20 minutes. No displacement of the orotracheal tube, vomiting, or gastrointestinal bleeding was observed. Frequent complication was displacement of the nasogastric tube in 41 (47%) patients. Severe right ventricular (RV) dysfunction was detected in 21 (24%) patients and acute cor pulmonale was diagnosed in 36 (41%) patients.Conclusion: Our results show the importance of assessing RV function during the course of severe respiratory distress and the value of TEE for hemodynamic assessment in PP.
