Abstract:

BACKGROUND: Continuous blood purification can remove cytokines and inflammatory mediators, maintain homeostasis and prevent the occurrence of multiple organ dysfunction syndrome in patients with severe pancreatitis, which has become the main therapy for severe pancreatitis. Since the hemodialysis technology began to be applied clinically, the biological and physicochemical properties of hemodialysis membrane materials have been studied. A variety of hemodialysis membranes have been developed in order to improve the biocompatibility and anticoagulant effect in vitro.
OBJECTIVE: To investigate the application effect of hemodialysis membranes on severe pancreatitis.
METHODS: Ten Wistar rats were selected to make rat models of severe pancreatitis and then were randomized into two groups (n=5 per group): homophone membrane group and polysulfone membrane group. Hemodialysis- related biochemical parameters were detected in the two groups.
RESULTS AND CONCLUSION: Compared with the homophone membrane, ultrafiltration coefficient, creatinine clearance, blood urea nitrogen clearance, phosphorus clearance, number of circulating endothelial cells, and levels of plasma nitric oxide and asymmetric dimethylarginine were significantly lower in the polysulfone membrane group (P < 0.05). Vitamin B12 clearance and amount of pre-congestion increased significantly in the polysulfone membrane group as compared with the homophone membrane (P < 0.05). These findings indicate that the polysulfone membrane for hemodialysis has good biocompatibility, and keeps a stable environment in vivo for severe pancreatitis patients.
