Hemodiafiltration is initiated in hemodynamically unstable patients in intensive care units. In some patients, additional devices called cytokine filters or sepsis filters are added to remove inflammatory cytokines. Data obtained from hemograms, such as platelet lymphocytosis ratio, are used in the diagnosis or prognosis of many diseases. This study focuses on the change in hemogram rates in patients who received hemofiltration and sepsis filters.

Inclusion Criteria:

• Data of patients who were monitored in the Intensive Care between January 2020 and December 2022 and who were applied sepsis filters

Exclusion Criteria:

• -Patients who underwent hemodiafiltration with sepsis filter but could not be followed for 72 hours (death, etc.)

Hemodiafiltration is started on patients in intensive care units. This study focuses on the change in hemogram rates in patients who underwent hemofiltration and had sepsis filters placed.
