Hepatic Failure, Plasma Exchange
Conditions
Brief summary
At present, there is no comparative study between the simple plasma exchange and plasma diafiltration (PDF), and no further exploration of optimal plasma dose in PDF treatment. Therefore, this prospective randomized cohort study aims to compare the safety and effectiveness of the tree groups(simple plasma exchange group, conventional PDF treatment group, less plasma PDF treatment group)by collecting SOFA score, 3-month survival rate, MELD score, and the times of artificial liver treatment , blood cell variables, cytokines(e.g. TNFα ), pre- and post-treatment plasma ammonia levels. Thus, it is to provide a safer and more effective artificial liver treatment with less plasma dose.
Interventions
simple plasma exchange treatment
conventional PDF treatment group
less plasma Plasma diafiltration treatment
