Early Use of Polymyxin B Hemoperfusion in Abdominal Sepsis

This clinical study designed as a prospective, open labelled, multi-centre, RCT will be carried out to evaluate if direct hemoperfusion with polymyxin B immobilized fiber column (PMX) is superior to conventional medical therapy for sepsis, for patients with sepsis arising from abdominal cavity infection, accompanied by the failure of one or more organs. 120 patients (60 treatment/60 control) will be considered in this study. Those patients fulfilling inclusion criteria and not having exclusion criteria will be randomly allocated to one of two study groups. One group will be treated with PMX (PMX group) and the other will receive a "standard therapy" for sepsis (control group). All patients will receive full intensive care management, including fluid resuscitation, vasopressors, antimicrobial chemotherapy, ventilatory support, and renal replacement therapy, if required. Each patient will be followed up for 28 days after study entry.
