Abstract:
Objective To evaluate the novel hybrid liver and renal support system the safety and efficacy of the treatment of Tibet mini pig model of renal failure .Methods Five Tibet miniature pig bilateral renal artery ligation approached to construct the models of renal failure ,treatment group was treated with therapy (CRRT mode) of the novel hybrid liver and renal support system after modeling ,while the control group received no treatment .Drawning venous blood endotoxin ,biochemical tests and aerobic anae‐robic culture when in the treatment of 0 ,4 ,8 h;then we observed the changes of biochemical indicators in Tibet mini pigs before and after treatment ;we recorded machine pressure monitoring indicators every 2 hour during treatment .Results The model of renal failure of two experimental animals were successfully constructed .The general condition of treatment group was improved after treated by the novel hybrid liver and renal support system ,while the control groups continued to deteriorate .The experimental ani‐mals did not appear abnormal ECG during the experiment .Two groups of animals showed no statistics significant difference (P>0 .05) in the period of 0 h .In the remaining period ,heart rate and respiratory rate in treatment group was significantly reduced(P<0 .05) ,while oxygen saturation and mean arterial pressure were significantly increased compared to control group(P<0 .05) .There was no differences of biochemical indicators between two groups before modeling (P>0 .05);after modeling both groups biochemi‐cal indicators was significantly increased compared with baseline (P<0 .05);after treatment of the hybrid liver and renal support systems in the treatment group ,the biochemical parameters were significantly decreased compared with baseline ,the difference was statistically significant different(P<0 .05) ,while the control group did not change significantly .Blood endotoxin measured results were less than 0 .5 EU/mL ,arteriovenous end aerobic anaerobic culture showed no bacterial growth .Pathological examination showed significant swelling of the renal tubular epithelium and tubular necrosis .Conclusion The novel hybrid liver and renal sup‐port system for the treatment of Tibet mini‐pig model of renal failure is safe and effective ,and it can be further attempts for clinical trials .
