THE ROLE OF FLUMAZENIL IN THE MANAGEMENT OF PATIENTS WITH ACUTE ALTERATION OF MENTAL STATUS IN THE EMERGENCY DEPARTMENT

1 There are a few case reports which suggest that flumazenil can be us ed as a diagnostic tool in coma of unknown aetiology but no large scal e studies have proved its efficacy and cost-effectiveness. 2 Fifty fiv e patients with acute alteration of mental status of unknown aetiology were enrolled prospectively during a time period of one year. Flumaze nil was injected intravenously in a regimen of 0.3 mg in the first min ute followed by alternate 0.2 mg, 0.3 mg doses every minute until a to tal dose of 1 mg was given or until the patients responded. 3 Patients were divided into two groups based on their response to flumazenil: G roup 1, responders and Group 2, non-responders, The hospital stay was shortened significantly and interventional procedures, such as CT of b rain and endotracheal intubation, were rendered unnecessary in several patients in Group 1. The Group 1 patients had a more favourable outco me than that of Group 2. 4 We concluded that flumazenil may serve as a useful tool in diagnosis and management of carefully selected patient s with acute alteration of mental status.
