Artificial liver support gained considerable interest in recent years due to the development of various albumin dialysis systems, which prolong survival of some patients with acute liver failure (ALF). Τhis study aims to examine the role of peritoneal albumin dialysis in a postoperative ALF model. ALF was induced in 14 female Landrace pigs by a combination of major liver resection (70-75% of total parenchyma) and ischemic-reperfusion injury on the liver remnant. Animals were randomly divided in two groups (n = 7 each). Both were monitored for 12 h of reperfusion and received peritoneal dialysis for 6 h, beginning 6 h after reperfusion. The albumin group received an albumin-rich solution and the control group received albumin-free solution. The control group gradually developed intracranial hypertension, whereas, in the albumin group, rise in the intracranial pressure was substantially attenuated (P < 0.01, t = 12 h). Albumin-treated animals had significantly lower levels of ammonia (P < 0.01), total bile acids (P < 0.01), free fatty acids (P < 0.05), lactate (P < 0.01), and total bilirubin (P < 0.05). Liver malondialdehyde and protein carbonyl were significantly reduced (P = 0.007 and P = 0.001 at t = 12 h) after albumin dialysis. Results suggest that this method may become a useful adjunct in the management of ALF, thus, justifying further study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
