Abstract
Routine blood samples of 145 consecutive patients seen in the Los Angeles County, California, USA, Psychiatric Hospital Emergency Room during a 48 h weekday period in June 1979 were examined for phencyclidine (PCP) using a sensitive and specific gas capillary gas chromatographic nitrogen detector (GC2-N) method. Of these 145 samples, 63 (43.4%) were positive and PCP levels ranged 0.34-142.9 ng/ml (.times. 14.6 ng/ml .+-. 3.4 SEM, standard error of the mean). An analysis of the records of these 63 patients revealed a wide variety of psychotic clinical pictures resembling mania, depression or schizophrenia with relatively few of the supposedly characteristic manifestations of PCP intoxication. Each of the 63 patients had at least 1 manifestation of toxic psychosis and/or acute delirium, in addition to the florid symptoms characteristic of functional states. PCP measurement, pharmacokinetics and the possible relationships of this intoxication to the psychiatric manifestations are discussed.
