Extracorporeal blood purification (EBP) therapies have shown promise as potential rescue treatments for patientswith septic shock. However, precise evidence regarding their effectiveness is lacking. This case-control study aimed to evaluate the 28-day survival benefit of a resin cartridge-based EBP therapy compared to conventional therapies in patients with septic shock.Materials and methods: The study sample was collected retrospectively from the medical records of patients admitted to the intensivecare unit (ICU) between 2015 and 2020. The study included patients with septic shock aged ≥18 years who had ICU stays >96 h andexcluded those lost to follow-up by 28 days or readmitted. First, 28-day survival was compared between EBP patients and 1:1 matchedconventionally treated controls. Second, the EBP patients were evaluated for clinical and laboratory improvements within 72 h of EBPtherapy.Results: Of 3742 patients, 391 were included in this study, of whom 129 received EBP therapy and had a 28-day survival rate of 44%,compared to 262 matched controls who received conventional therapy alone and had a survival rate of 33% (p = 0.001, log-rank =0.05, number needed to treat = 8, and odds ratio = 1.7). After receiving EBP therapy for 72 h, improvements were observed in theSequential Organ Failure Assessment scores (p < 0.05), shock indices (p < 0.05), partial pressure of oxygen in the arterial blood to the fractionof inspiratory oxygen concentration ratios (p < 0.001), vasopressor requirements (p < 0.001), pH (p < 0.05), lactate levels (p < 0.001), andC-reactive protein levels (p < 0.05).Conclusion: The findings suggest that administering resin cartridge-based EBP therapy to patients with septic shock may improve theirsurvival compared to conventional therapies.
