We performed a retrospective chart analysis of 33 patients with an Emergency Department discharge diagnosis of phencyclidine (PCP) intoxication. All 33 cases presented to the Emergency Department between November 1986 and April 1987. Thirty of the 33 patients (91%) were classified as mildly intoxicated (per clinical syndrome as described by Aronow and Done) while the remaining 3 patients (9%) were moderately intoxicated. Two of the patients (6%) required benzodiazepine therapy for agitation while an additional 3 patients (9%) required haloperidol for psychotic symptoms. Twenty-three patients (70%) did not require any medication. Of particular interest was our finding that 11 of the 27 males (41%) required leather restraints for agitation or violent behavior while none of the 6 female patients required leather restraints (Fisher's exact test, p = 0.00078). While nursing perception of physical strength may be a confounder, level of agitation and violent behavior is our primary indication for use of restraints. We believe that there is a sexual disparity in level of agitation and violent behavior induced by PCP. We hypothesize that this may be due to pharmacokinetic factors (such as difference in body fat distribution between the sexes) or biological differences in the central nervous system.

As phencyclidine hydrochloride (PCP) has become one of the more frequently abused drugs in the United States, there has been increasing interest in its effect on the fetus and neonate of the pregnant abuser. Two groups of women enrolled in a comprehensive perinatal addiction program were studied: 7 women abused PCP prior to and during pregnancy, and these women were compared to a group of 27 drug-free women. No differences between the two groups were seen in maternal age, gravidity, gestational age or Apgar scores. At birth, there was no difference in birth weight, length, or head circumference between the two groups of neonates. The most characteristic features of the PCP-exposed infants were the sudden outbursts of agitation and rapid changes in level of consciousness, similar to responses described in adults intoxicated with PCP. Scores on the Brazelton Neonatal Behavioral Assessment Scale revealed a significant increase in lability of states and poor consolability in PCP-exposed infants. 3-month scores on the Bayley Scales of Infant Development revealed no significant difference between the two groups of infants.

Phencyclidine (PCP), a widely abused drug currently, has multiple pharmacological actions, including psychotomimetic [1], anesthetic [2], sympathomimetic [2], anticholinergic [3-7], and dopaminergic [8-10]. Similarly, PCP intoxication in man can present with diverse symptoms: schizophrenia-like delusions and hallucinations; mania; violence, dyskinetic, catatonic, or stereotyped movements; hypertension; and coma [11, 12]. There is general agreement that the treatment of PCP intoxication includes support of vital functions and acidification of the urine [13]. However, there is no known specific antidote for PCP toxicity. Although diazepam [13], haloperidol [14, 15], and chlorpromazine [16] have been reported to improve the agitation and psychotic symptoms caused by PCP, the therapeutic efficacy of these agents has rarely been documented with objective clinical measures. Recently we found that intramuscular physostigmine and haloperidol [17, 18] improved several symptoms of acute PCP intoxication as measured by the Brief Psychiatric Rating Scale (BPRS) [19].

In 1,000 cases of phencyclidine (PCP) intoxication evaluated at the time of first examination in an emergency department, the incidence of "typical" findings was found to be lower than has been reported previously. Nystagmus and hypertension occurred in only 57% of our cases; some patients had only one of these findings and many had neither. The incidence of violence was 35%; bizarre behavior, 29%; and agitation, 34%. Changes in sensorium consisted of coma, lethargy/stupor, and acute brain syndrome; however, 46% of patients were alert and oriented. Motor signs included grand mal seizures, generalized rigidity, localized dystonias, catalepsy, and athetosis. Profuse diaphoresis, hypersalivation, bronchospasm, and urinary retention occurred in less than 5%. A small percentage had severe disturbances in vital signs, including three cases (0.3%) of cardiac arrest and 28 cases (2.8%) of apnea. Hypoglycemia and elevated serum CPK, uric acid, and SGOT/SPGT were common. Urine PCP levels did not correlate with the severity of the clinical findings.

Phencyclidine (PCP) is a popular illicit drug often misrepresented as some other hallucinogenic substance and distributed in widely varying dosage forms and strengths. Users of hallucinogenic drugs may present with unintentional PCP overdoses. Toxicological laboratory analyses are essential to establish the diagnosis. In nine admitted overdose patients, the consciousness level ranged from alert to comatose on presentation, and all showed a prolonged recovery phase with agitation and toxic psychosis. Severe behavior disorder, paranoid ideation, and amnesia for the entire period of in-hospital stay are characteristic. In very high dose patients, shallow respiratory excursions and periods of apnoea and cyanosis coincided with generalized extensor spasm and spasm of neck muscles. Excessive bronchial secretions, gross ataxia, opisthotonic posturing, and grimacing occur. PCP toxic psychosis should be considered in drug-abusing patients presenting with schizophrenic-like symptoms, psychosis, or other bizarre behavior, whether or not they admit to taking PCP.

Phencyclidine hydrochloride (PCP) is a psychoactive drug that in small doses produces agitation, excitement, and disorientation, but in larger doses results in stupor, convulsions, coma, and death. Two accident victims under the effects of phencyclidine were in coma. A history of phencyclidine abuse was not initially available in either instance. Head injury was suspected in both patients, although their neurological symptoms suggested a state of sensory blockade. Phencyclidine abuse should be considered in all patients with atypical coma despite a clear history of trauma.

In our country, abuse of methamphetamine has increased. Furthermore, dealings of other drugs by using internet have increased. But, the poison cases of 3,4-methylenedioxymethamphetamine (MDMA) and phencyclidine (PCP) have never been reported in our country. We report an MDMA poison case and a PCP poison case. We could detect MDMA, MDA or PCP by GC-MS from urine and serum of patients admitted to the critical care medical center of Nippon Medical School. Case 1: A 23-year-old foreign female was admitted to our hospital because of disturbance of consciousness. Her friend said that she had been found lying on the floor of the bathroom after taking a tablet. The screening test by Triage showed AMP positive. Not methamphetamine but MDMA and MDA were detected from urine and serum of the patient by GC-MS. Case 2: A 27-year-old foreign female was admitted to our hospital because of restlessness and excitement. Her friend said that she had become restless and excited after taking 15-30 tablets of Tylenol. The screening by Triage showed BZO and PCP positive. Not acetaminophen but PCP was detected in the patient's sample by GC-MS. Drug abuse has expanded to Japan over the border. New responses to abuse drugs with respect to medical treatment and drug analyses should be established.

The history, symptoms, diagnosis and treatment of phencyclidine hydrochloride (PCP) intoxication, the pharmacology of PCP and the detection, identification and analysis of PCP are reviewed. The history of PCP from its synthesis in the early 1950s to the present is discussed. Intoxication with low to moderate doses of PCP resembles an acute, confusing state. High doses may cause serious neurological and cardiovascular complications and the patient is often comatose for several days. Treatment involves supportive psychological and medical measures, and acidification of the urine may further increase PCP clearance. The metabolism of PCP involves primarily hydroxylation followed by conjugation and elimination in the urine. Analysis can be accomplished by a number of instrumental methods, and several commercial test kits based on antigen-antibody interactions are available. PCP's effect on human performance and behaviour is due to its ability to alter the perception of reality in the user. PCP causes a range of effects that include hallucinations, delirium, disorientation, agitation, muscle rigidity, ataxia, nystagmus, seizures, and stupor. PCP has stimulant, depressant, hallucinogenic and analgesic effects. Which of these will be most pronounced is unpredictable and depends on the user's personality, psychological state and the environment of use. The impairment can manifest itself as over-aggressive or reckless driving behavior, or may mimic depressant effects due to PCP's anesthetic and depressant effect.
