Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention group (Lipopolysaccharide adsorption group) will receive Alteco Lipopolysaccharide adsorber in addition to standard medical therapy. Patient will have hemodialysis catheter insertion over femoral vein or internal jugular vein for blood access. Hemoperfusion (a technique involves passing large volumes of blood over an adsorbent substance) using Alteco Lipopolysaccharide adsorber at blood flow rate of 120-150ml/h will be conducted as soon as possible after randomization. Each patient will have two 2-hourly sessions of Lipopolysaccharide adsorption 24hrs apart. In between, renal replacement therapy will be provided if clinically indicated based on usual practice

Treatment: Devices
Comparator / control treatment
Control group will have standard medical therapy for septic shock namely: control of septic sources, antibiotic, fluid challenge, vasopressor and stress dose steroid. Renal replacement therapy will be provided as indicated.
