The study plans to recruit 192 participants from intensive care units, who will be randomly assigned to either the intervention group (oXiris set) or the control group (ST 150 set). The primary endpoint is the reduction in norepinephrine equivalence following the initiation of CRRT. Key secondary endpoints include changes in cardiac index and systemic vascular resistance index, as measured by pulse indicator continuous cardiac output, following CRRT initiation, as well as overall survival and kidney recovery rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>The study will be conducted in accordance with the Declaration of Helsinki and Good Clinical Practice.
