The Plasma Diafiltration Therapy of Hepatic Failure

Not Applicable
Conditions
Hepatic Failure
Plasma Exchange
Interventions
Procedure: conventional PDF treatment group
Procedure: simple plasma exchange
Procedure: less plasma PDF treatment group
Registration Number
NCT03560414
Lead Sponsor
Fuzhou General Hospital
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.

The replacement fluid flow rate is 500 ml/h, the dialysate flow rate is 3000 ml/h, the blood flow rate is 100-140 ml/min, and the ultrafiltration volume is 0 ml/h.
simple plasma exchange groupsimple plasma exchangeThe mode is CVVH in CRRT machine, the treatment duration is 2h-3h, the application plasma volume is 40ml/Kg, the replacement fluid flow rate is 1000ml/h, the blood flow rate is 100-140 ml/min, and the ultrafiltration volume is 0ml/h.
less plasma PDF treatment groupless plasma PDF treatment groupThe mode of conventional PDF treatment group is also CVVHDF in CRRT machine, and the duration of treatment is 3h. All patients are required to apply plasma 1000ml. Use plasma substitutes: 300ml NS+200ml 5% albumin. The replacement fluid flow rate is 500 ml/h, the dialysate flow rate is 3000 ml/h, the blood flow rate is 100-140 ml/min, and the ultrafiltration volume is 0 ml/h.
