BACKGROUND Acute psychotic illness , especially when associated with agitated or violent behaviour , can require urgent pharmacological tranquillisation or sedation .
In several countries , clinicians often use benzodiazepines ( either alone or in combination with antipsychotics ) for this outcome .
OBJECTIVES To estimate the effects of benzodiazepines , alone or in combination with antipsychotics , when compared with placebo or antipsychotics , alone or in combination with antihistamines , to control disturbed behaviour and reduce psychotic symptoms .
TREC-Rio trial: a randomised controlled trial for rapid tranquillisation for agitated patients in emergency psychiatric rooms [ISRCTN44153243]
Background Agitated or violent patients constitute 10 % of all emergency psychiatric treatment . Management guidelines , the preferred treatment of clinicians and clinical practice all differ . Systematic review s show that all relevant studies are small and none are likely to have adequate power to show true differences between treatments . Worldwide , current treatment is not based on evidence from r and omised trials . In Brazil , the combination haloperidol-promethazine is frequently used , but no studies involving this mix exist . Methods TREC-Rio ( Tranquilização Rápida-Ensaio Clínico [ Translation : Rapid Tranquillisation- Clinical Trial ] ) will compare midazolam with haloperidol-promethazine mix for treatment of agitated patients in emergency psychiatric rooms of Rio de Janeiro , Brazil . TREC-Rio is a r and omised , controlled , pragmatic and open study . Primary measure of outcome is tranquillisation at 20 minutes but effects on other measures of morbidity will also be assessed . TREC-Rio will involve the collaboration of as many health care professionals based in four psychiatric emergency rooms of Rio as possible . Because the design of this trial does not substantially complicate clinical management , and in several aspects simplifies it , the study can be large , and treatments used in everyday practice can be evaluated
