[Patients in a state of agitation at the admission service of a Rouen hospital emergency department].

Objective: To determine the incidence and causes of agitation states in patients presenting at the Rouen University Hospital emergency room and to analyze the management scheme.

Patients And Method: A prospective study was conducted over a 9 month period in 100 consecutive patients presenting a state of agitation assessed using the Overt Aggression Scale. A pre-planned management protocol was applied.

Results: The incidence of states of agitation was 0.56%. There were 43 women and 57 men, mean age 33 years. Most of the agitated patients were admitted between 6 p.m. and 4 a.m. (69%). Over the 9 month period, 2 patients were admitted twice for agitation and 2 absconded. Low glucose level was the cause of agitation in 4 cases. Alcohol and/or drug use concerned 73% of the agitated patients and was the most frequently observed triggering factor (17%). Only 6% of the patients had a regular employment. Physical restraining measures and sedation were required in 86% and 84% of the cases respectively. Among 67 patients given loxapine for sedation, 2 developed acute dyskinesia and 9 low blood pressure. One out of 4 patients were referred to a psychiatric unit.

Conclusion: Patients in a state of agitation are young, often female, and in a difficult socio-economic situation. Hypoglycemia is the main differential diagnosis. A triggering factor can often be identified. A state of agitation is not a repetitive condition but occurs as a short-lived episode in the patientís history. Such patients need rapid care to avoid further aggravation and disruption of the emergency room activity, and to prevent the patient from fleeing. Loxapine provides effective sedation but requires regular monitoring of blood pressure and can provoke acute dyskinesia in young subjects.
