Ten-Year Retrospective Analysis of Continuous Renal Replacement Therapy in Burn Patients: Impact on Survival and Timing of Initiation

BACKGROUND Acute kidney injury (AKI) is a common issue in intensive care units and is a potentially lethal consequence of severe burns. In severely burned patients with non-renal indications, renal replacement treatment is frequently used. This study's aim was to compile a 10-year summary of continuous renal replacement therapy (CRRT) experience at a single burn center, including patient outcomes, effectiveness, and potential complications in the context of severe burns. MATERIAL AND METHODS This retrospective analysis included the clinical data from 723 burned patients. The data analysis of 300 patients with CRRT therapy included clinical data, laboratory tests, and CRRT parameters. The study group was split into 2 subgroups regarding onset of CRRT: early (up to 7 days after the trauma) and late. RESULTS Age, burn extent, length of stay, and inhalation injury all had an impact on survival. Early CRRT was linked to a greater probability of death (P<0.005). Upon admission to the burn center, patients with early CRRT exhibited a bigger burn area, higher Baux and SOFA scores, and were younger (P<0.05). Sepsis was diagnosed more frequently in the late CRRT group. CONCLUSIONS Our findings show that patients who require CRRT within the first 7 days following a burn injury have a poorer prognosis; however, this is not due to CRRT's effect, but rather to the trauma's severity. Future studies should explore long-term patient outcomes of CRRT among burn patients.
