Objectives: Butyrophenones have been reported to provide effective migraine relief in the emergency department (ED). We conducted a systematic review of the evidence for their use in the ED. Data source: We searched the Cochrane, Medline, Embase, and CINAHL databases. Study selection: Included studies were randomized trials of a parenteral butyrophenone (droperidol, haloperidol) versus placebo or a comparator in migraine or benign headache with results available in English. Study quality was determined using the Jadad score. Six articles were included. Data extraction: Primary outcomes were subjective or objective headache relief (. 50% improvement in visual analogue scale scores). Secondary outcomes included side effects. We reported pooled odds ratios (ORs) with their 95% confidence intervals (CIs) for subjective or objective headache relief for butyrophenones versus placebo or comparator agents. Data synthesis: Three studies reported subjective headache relief with a butyrophenone versus placebo or meperidine in migraine. Two studies reported objective headache relief with droperidol versus prochlorperazine, whereas one study compared droperidol versus olanzapine in benign headache. The pooled OR for subjective headache relief was 8.08 (95% CI 1.54-42.30) for a butyrophenone versus placebo, whereas it was 1.50 (95% CI 0.33-6.77) for droperidol versus meperidine in migraine. The pooled OR for objective headache relief was 2.96 (95% CI 1.36-6.43) for droperidol versus prochlorperazine in benign headache. Rates of side effects were 10 to 45%; akathesia and sedation were the most common. Conclusions: Butyrophenones are effective for the relief of migraine or benign headache. However, adverse effects make it difficult to recommend butyrophenones above agents with similar effectiveness and fewer problems.
RÉ SUMÉObjectif : Il a é té signalé que les butyrophé nones soulageaient les migraines dans les services d'urgence. Nous avons procé dé à une analyse systé matique sur leur utilisation à l'urgence. Source des donné es : Nous avons interrogé les bases de donné es Cochrane, Medline, Embase et CINAHL. Sé lection des é tudes : Nous avons retenu les essais randomisé s d'un butyrophé none parenté ral (dropé ridol, halopé ridol) contre un placebo ou un comparateur en cas de migraine ou de cé phalé e bé nigne. Les ré sultats devaient ê tre disponibles en anglais. Nous avons é valué la qualité des essais selon le score de Jadad. Six articles ont é té retenus. Extraction des donné es : Les principaux critè res d'é valuation é taient le soulagement subjectif ou objectif de maux de tê te (. 50 % d'amé lioration selon l'é chelle visuelle analogique). Les critè res secondaires d'é valuation é taient entre autres les effets secondaires. Nous avons inclus les rapports de cotes combiné s (RC) avec intervalle de confiance à 95 % (IC) pour le soulagement subjectif ou objectif de maux de tê te pour le groupe butyrophé nones par rapport au groupe placebo ou autres comparateurs. Synthè se des donné es : Trois é tudes ont signal...
