Comparison of two-bag and three-bag acetylcysteine regimens in the treatment of paracetamol poisoning: a systematic review and meta-analysis.

Introduction: Worldwide, paracetamol poisoning is a common cause of acute liver failure and referral to transplant centers. Acetylcysteine has long been the mainstay of treatment, but recent literature suggests that a simplification of the "three-bag" method may decrease adverse effects. Our primary hypothesis is that a simplified dosing regimen (two-bag regimen) is non-inferior to the three-bag method in preventing liver injury.
