The impact of different antiepileptic drugs on the sedation of children during magnetic resonance imaging
Background and objectives: The induction and inhibition of cytochrome P450 isoenzymes by antiepileptic drugs lead to changes in the clearance of anesthetic drugs eliminated via hepatic metabolism. We investigated the duration of the sedation and additional anesthetic needs during magnetic resonance...

Background and objectives: The induction and inhibition of cytochrome P450 isoenzymes by antiepileptic drugs lead to changes in the clearance of anesthetic drugs eliminated via hepatic metabolism. We investigated the duration of the sedation and additional anesthetic needs during magnetic resonance imaging in epileptic children receiving antiepileptic drugs that cause either enzyme induction or inhibition. Methods: In American Society of Anesthesiology I–II, 120 children aged 3–10 years were included. Group 1: children using antiepileptic drugs that cause cytochrome P450 enzyme induction; Group 2: those using antiepileptic drugs that cause inhibition; and Group 3: those that did not use antiepileptic drugs. Sedation was induced with the use of 0.05 mg kg−1 midazolam and 1 mg kg−1 propofol. An additional 0.05 mg kg−1 of midazolam and rescue propofol (0.5 mg kg−1) were administered and repeated to maintain sedation. The duration of sedation and the additional sedation needed were compared. Results: The duration of the initial dose was significantly shorter in Group I compared with groups II and III (p = 0.001, p = 0.003, respectively). It was significantly longer in Group II compared with groups I and III (p = 0.001, p = 0.029, respectively). The additional midazolam needed for adequate sedation was increased in Group I when compared with groups II and III (p = 0.010, p = 0.001, respectively). In addition, the rescue propofol dose was significantly higher only in Group I when compared with Group III (p = 0.002). Conclusion: In epileptic children, the response variability to the initial sedative agents during the magnetic resonance imaging procedure resulting from the inhibition or induction of the cytochrome P450 isoenzymes by the antiepileptic drugs mandated the titration of anesthetic agents. Resumo: Justificativa e objetivos: A indução e a inibição das isoenzimas do citocromo P450 pelos medicamentos antiepilépticos levam a alterações na depuração de medicamentos anestésicos eliminados pelo metabolismo hepático. Investigamos a duração da sedação e a necessidade adicional de anestésicos durante a ressonância magnética em crianças epilépticas que receberam antiepilépticos que causam a indução ou a inibição de enzimas. Métodos: Foram incluídas no estudo 120 crianças, estado físico ASA I-II, entre 3-10 anos. Grupo 1: em uso de antiepilépticos que causam a indução de enzimas do citocromo P450; Grupo 2: em uso de antiepilépticos que causam a inibição de enzimas do citocromo P450; e Grupo 3: que não usavam antiepilépticos. A sedação foi induzida com midazolam (0,05 mg kg−1) e propofol (1 mg kg−1). Um adicional de 0,05 mg kg−1 de midazolam e resgate com 0,5 mg kg−1 de propofol foram administrados e repetidos para manter a sedação. A duração da sedação e a sedação adicional necessária foram comparadas. Resultados: A duração da dose inicial foi significativamente menor no Grupo I em comparação com os grupos II e III (p = 0,001, p = 0,003, respectivamente) e significativamente maior no Grupo II em comparação com os grupos I e III (p = 0,001, p = 0,029, respectivamente). A necessidade de midazolam adicional para sedação adequada foi maior no Grupo I em comparação com os grupos II e III (p = 0,010, p = 0,001, respectivamente). Além disso, a dose de resgate de propofol foi significativamente maior apenas no Grupo I em comparação com o Grupo III (p = 0,002). Conclusão: Em crianças epilépticas, a variabilidade da resposta aos agentes sedativos iniciais durante a ressonância magnética, resultante da inibição ou indução das isoenzimas do citocromo P450 pelos medicamentos antiepiléticos, exigiu a titulação dos agentes anestésicos.
