title: Emergency treatment of acute psychosis.
abstract: The author reviews the evolution of emergency psychiatric practice over the past 20 years--from the concept of high-dose antipsychotic medication to the more rational treatment approach for acute psychosis made possible by modern pharmacodynamic insight and the availability of new pharmacotherapeutic agents. A decision tree for current practice in the rapid tranquilization of agitated, apparently psychotic patients is described.
