Reporting Groups
N-acetycylcysteine Each eligible Acute Liver Failure patient will be given N-acetylcysteine (NAC), beginning at a dose of 150 mg/kg bodyweight in 250 ml 5% dextrose over one hour, followed by 50 mg/kg in 500 ml 5% dextrose over four hours, and 125 mg/kg in 1000 ml 5% dextrose over 19 hours, then 150 mg/kg in 1000 ml 5% dextrose per 24 hours for an additional 48 hours. The patient will be on continuous NAC infusion for a total of 72 hours.
