This edition of this manual contains facts and advice for clinicians on the effective management of psychiatric emergencies. Presenting complete differential diagnoses and principles of management for the full range of psychiatric crises, the manual is organized into five concise parts: fundamental topics in emergency psychiatry; special problems and patient populations; emergency evaluation and treatment of major psychiatric disorders; medical-psychiatric emergencies; and drug abuse emergencies. Revised and expanded, the third edition features new chapters on emergency evaluation of children and adolescents, homeless patients, psychiatric symptoms of HIV infection and AIDS, mentally retarded patients and emergency department repeaters, as well as a new appendix on interpreting drug screens.
