Study type Participant information sheet
Scientific titleA double blind randomised prospective study on the effect of premedication on pain perception: functional magnetic resonance imaging (fMRI) study of healthy volunteers
Study acronymPPPMRI
Study objectivesPremedication reduces pain-related cerebral activation.
Ethics approval(s)Local medical ethics committee (Comité de protection des personnes Ouest II) approved on the 13th March 2009 (ref: 2008-36)
Health condition(s) or problem(s) studiedPain perception
InterventionPlacebo, hydoxyzine or midazolam ingestion one hour before sequential electrical right forearm pain stimulation and fMRI examination.

The interventions consist of a unique dose ingestion of placebo, hydroxyzine (0.9 mg/kg), and midazolam (0.1 mg/kg) in orange juice, in a randomised design with one week between each session. The follow-up is 6 hours in each arm.
Intervention typeDrug
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Hydoxyzine, midazolam
Primary outcome measure(s)

Volume of central pain matrix activation on fMRI, obtained by contrasting painful stimulation period with resting state period during fMRI recording.

Key secondary outcome measure(s)

Visual analogic pain score, measured at the end of each 6 seconds painful stimulation period.
