High-volume Versus Standard Volume Plasma Exchange in Patients With Acute Liver Failure With Cerebral Edema

Experimental- High Volume Therapeutic Plasma Exchange at (8 - 9 litres of plasma would be exchanged in each patient over 6 - 8 hours)

Active Comparator - The standard volume strategy would be performed centrifugation technique with Plasma volume varying from 1.5 - 2.5 times the plasma - volume along with Standard Medical Treatment.
