This experimental porcine study was done to evaluate the effects of Fas-directed extracorporeal immune therapy with a leukocyte inhibition module LIM on hemodynamics neutrophil tissue infiltration and tissue damage after hemorrhagic shock resuscitation. Methods In a prospective controlled double-armed animal trial 24 Munich Mini Pigs kg were rapidly haemorrhaged to reach a mean arterial pressure MAP of 35 5 mmHg maintained hypotensive for 45 minutes and then were resuscitated with Ringer solution to baseline MAP With beginning of resuscitation 12 pigs underwent extracorporeal immune therapy for 3 hours LIM group and 12 pigs were resuscitated according to standard medical care SMC . Haemodynamics haematologic metabolic and organ specific damage parameters were monitored. Neutrophil infiltration was analyzed histologically after 48 and 72 hours. Lipid peroxidation and apoptosis were specifically determined in lung bowel and liver. Results In the LIM group neutrophil counts were reduced versus SMC during extracorporeal immune therapy. After 72 hours the haemodynamic parameters MAP and cardiac output CO were significantly better in the LIM group. Histological analyses showed reduction of shock-related neutrophil tissue infiltration in the LIM group especially in .
