title: Analysis of sexual disparity of violent behavior in PCP intoxication.
abstract: 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.
