Sequential plasmafilter-dialysis with slow continuous hemofiltration: additional treatment for sepsis-induced AOSF patients

Five patients with sepsis-induced acute organ system failure were treated by sequential plasmafilterdialysis with slow continuous hemofiltration in addition to conventional therapy. In this way, we were able to associate the possible clearance of mediators and toxic substances achieved by plasmapheresis with an improved clearance of nitrogen waste products, since we added diffusion to the convective effect of hemofiltration. The hypercatabolism was well controlled, and there was a significant improvement in cardiorespiratory parameters at the same time. These patients were retrospectively compared with four conventionally treated patients (100% mortality) and with six others treated by association of conventional therapy and continuous arteriovenous hemodialysis (50% mortality). Despite the small numbers of patients treated and the need of additional studies, our good results (all the patients survived) encourage us to use this approach as an adjunct of conventional therapeutic measures in oliguric and hypercatabolic AOSF patients.
