Internal Jugular Vein Cannulation in Prone Position.

Since 1970, prone decubitus (PD) has been used as adjuvant therapy to treat severe hypoxia in patients with acute respiratory distress syndrome (ARDS), and now with the COVID-19 pandemic, its use has become widespread in ICUs. ARDS is characterized by diffuse bilateral radiographic infiltrates, decreased respiratory compliance, small lung volumes, and severe hypoxemia. The placement of vascular access in PD seems to be feasible and safe, since, as has been described, the number of complications such as pneumothorax, bleeding, and arterial punctures are almost nil, especially when performed under ultrasound guidance. The patients who could benefit most from this procedure seem to be those with obesity, mainly with a body mass index greater than 30 kg/m2, in whom the return to the supine position may represent a risk of respiratory or hemodynamic deterioration.
