Toward acid- and heparin-free dialysis: the regional anticoagulation approach.

Background: In chronic intermittent hemodialysis, heparin is the standard anticoagulant as is the use of acid-containing dialysate. Regional anticoagulation (RA) with a calcium-free, citrate-containing dialysate has been developed. We compared RA using a calcium-free, citrate-free dialysate, routinely used in our center, versus systemic heparinization.

Impact of Dexamethasone and Inhaled Nitric Oxide on Severe Acute Kidney Injury in Critically Ill Patients with COVID-19.

Background: Acute kidney injury (AKI) is the second most frequent condition after acute respiratory distress syndrome (ARDS) in critically ill patients with severe COVID-19 and is strongly associated with mortality. The aim of this multicentric study was to assess the impact of the specific treatments of COVID-19 and ARDS on the risk of severe AKI in critically ill COVID-19 patients. Methods: In this cohort study, data from consecutive patients older than 18 years admitted to 6 ICUs for COVID-19-related ARDS requiring invasive mechanical ventilation were included.
