Fig. 2From: The effects of direct hemoperfusion using a polymyxin B-immobilized column in a pig model of severe Pseudomonas aeruginosa pneumoniaEndotoxin activity in the control and treatment group during study time. Data are reported as mean and standard error. Polymyxin B-immobilized fiber hemoperfusion was carried out for 3 h, after 30 and 50 h. a Endotoxin activity in all subjects. Group effect, p = 0.224; study time effect, p = 0.882; group * study time effect, p = 0.572. b Post hoc analysis in only animals with a decrease in mean arterial pressure ≥10 %, within 24 h from bacterial challenge. Group effect, p = 0.018; study time effect, p = 0.473; group * study time effect, p = 0.830Back to article page
