Preliminary study on the safety and efficacy of a new polymyxin B-immoblized resin column in treatment of LPS-induced sepsis beagles.

ABSTRACT:

Background

This study aims to assess the safety and efficacy of direct hemoperfusion using a new polymyxin B-immobilized resin column (disposable endotoxin adsorber, KCEA) in an endotoxin/ lipopolysaccharide (LPS)-induced sepsis model.

Methods

Eighteen beagles were randomized into 1 intervention group (KCEA group, n = 6) and 2 control groups (sham group and model group, n = 6 each). Sepsis was induced by continuous intravenous application of 0.5 mg/kg body weight of endotoxin for 60 min. An extracorporeal hemoperfusion device made with KCEA for endotoxin adsorption was used. Model group beagles received standard treatment with fluids and vasoactive drugs, KCEA group beagles received standard treatment and direct hemoperfusion of KCEA for 2 h, and sham group beagles were trea
