ABSTRACT
The decision trees that follow are based, with permission, on those of Dargan et al. (2001) and assume the availability of N-acetylcysteine for i.v. use. Although aimed primarily at the treatment of adults, the trees are valid for use in pregnant women and children. It should be emphasized that when patients are discharged they should receive written instructions to return if they develop vomiting or abdominal pain. Particular caution is advised in dealing with children who may have ingested multiple doses of paracetamol, and thus in whom an accurate assessment of the dose has not been possible.
