Continuous Veno-Venous Hemofiltration with oXiris Hemofilters for the Treatment of Fournier's Gangrene: A Case Report Series

Background Fournier's gangrene (FG) is a severe form of necrotizing fasciitis primarily caused by gram-negative bacteria. FG can rapidly progress to septic shock, resulting in high mortality rates. In the past, the management of the inflammatory response caused by gram-negative bacteria has been limited. Continuous Veno-Venous Hemofiltration with oXiris hemofilters (oXiris-CVVH) has shown promise in adsorbing inflammatory factors and endotoxins, making it an attractive approach for treating FG. This study aims to provide insights into the characteristics of patients with FG and septic shock who have been successfully treated using oXiris-CVVH, based on a series of patient cases. Results This study presents the management of 4 cases in the intensive care units of a tertiary hospital in southern China. The use of oXiris-CVVH in patients with septic shock and FG yielded valuable practical insights. Conclusion Based on the experience gained from these 4 cases, the utilization of oXiris-CVVH demonstrated potential in reducing the Sequential Organ Failure Assessment (SOFA) score, improving prognosis, and effectively lowering the levels of lactic acid and procalcitonin (PCT) in the blood. Additionally, it facilitated a reduction in the dosage of noradrenaline. Therefore, oXiris-CVVH should be considered as an adjunctive therapy in the treatment of patients with FG and septic shock.
