Brief summary

In coronavirus disease-2019 (COVID-19)-related ARDS (C-ARDS), especially in the severe form, increased shunt rate, impaired ventilation/perfusion ratio (V/Q), hypoxic pulmonary vasoconstriction inhibition, and increased immune microthrombosis may have similar effects on the right ventricle .The cardiopulmonary pathophysiology and outcomes of C-ARDS vary, and this variability requires monitoring to follow the diagnosis and treatment process. This study aimed to increase the treatment success of the prone position in C-ARDS and to provide a prognostic factor for survival by analyzing and monitoring heart-lung interactions. Therefore, we used transesophageal echocardiography (TEE) to evaluate the cardiopulmonary effects of prone position.

Detailed description

This prospective study included 30 moderate-to-severe C-ARDS patients who were treated with prone position in the first 48 hours of invasive mechanical ventilation support. It was evaluated with transesophageal echocardiography three times: before prone position (PP) (T0), the first hour of PP (T1), and the first hour of returning to the supine position (T0 + 24 hours) (T2) after 23 hours prone position treatment. Right ventricular end-diastolic area/left ventricular end-diastolic area (RVEDA/LVEDA) was preferred right ventricular evaluations as primer outcome. Static compliance (C-stat) was examined in the evaluation of the pulmonary effect of prone position as secondary outcome.
