Summary of major outcomes of pesticides of atropine in

Data are number (%)

£Diazinon, Phethoate, Acephate, Profenopos, Fenthion


Conclusions
Conclusions of atropine in

  • Titrated atropine dosing was associated with significantly less atropine toxicity

  • There is no difference in patient mortality

  • Atropine doses should be titrated against response and toxicity

  • The use of a structured monitoring sheet may assist in more appropriate atropine use
