Resumo

JUSTIFICATIVA E OBJETIVOS: O nosso objetivo foi investigar o efeito da "sedação multifásica" em crianças submetidas à Tomografia Computadorizada (TC) ou Ressonância Magnética (RM), em seus pais e nos anestesiologistas responsáveis. "Sedação multifásica" foi definida como "o nível de sedação pretendido obtido com um ou mais agentes através da mesma via ou vias diferentes com mais de uma administração". MATERIAL E MÉTODOS: Cem crianças e seus respectivos pais foram randomicamente designados para um dos dois grupos de estudo. Na fase 1, os pacientes do Grupo I receberam midazolam (0,5 mg.kg-1) em 5 mL de suco de frutas e os pacientes do Grupo II (grupo controle) receberam apenas suco de frutas. Na fase 2, após a canulação intravenosa (iv), bolus de propofol foi administrado para alcançar a sedação adequada para realização do exame de imagem. Os escores de ansiedade das crianças e de seus pais foram registrados usando a escala de Oucher e o IDATE, respectivamente, e a satisfação dos pais foi avaliada pela escala analógica visual (EAV). O número de tentativas para canulação iv, tempo de preparação e quantidade de hipnóticos foram registrados. RESULTADOS: O estado de ansiedade das crianças foi semelhante entre os grupos antes da pré-medicação, porém mais tarde esse nível foi menor no Grupo I. Antes do procedimento, o escore dos pais no IDATE foi semelhante, mas depois foi menor no Grupo I. A satisfação dos pais no Grupo I foi maior que no Grupo II. O número de tentativas de canulação iv e a dose necessária de propofol foi menor no Grupo I. CONCLUSÃO: O procedimento de "sedação multifásica" diminui a dor e a ansiedade das crianças e a ansiedade dos pais, aumentando a sua satisfação. Ele fornece uma sedação confortável e segura, pois possui um processo de preparação curto e sem problemas também para o anestesiologista responsável.

Abstract

BACKGROUND AND OBJECTIVES: We aimed to investigate the effect on children undergoing Computed Tomography (CT) or Magnetic Resonance Imaging (MRI), their parents and attending anesthesiologist of "multiphase sedation" which we define as "the intended sedation level achieved with one or more agents through the same or different routes with more than one administration". MATERIAL AND METHODS: One hundred children and their parents were randomly allocated to one of two study groups. In phase 1; in Group I the patients were given midazolam (0.5 mg.kg-1) in 5 mL fruit juice, and the ones in control group (Group II) were given only fruit juice. After intravenous (iv) cannulation; in phase II, boluses of propofol were given to achieve the adequate sedation for imaging. Anxiety scores of children and their parents were recorded using Oucher scale and STAI, respectively, and parental satisfaction was evaluated by visual analogue scale (VAS). The number of attempts for iv cannulation, length of time for preparation, and amount of hypnotics were recorded. RESULTS: Anxiety state of children was similar between groups before premedication, but later it was lower in Group I. Before procedure, STAI score of parents was similar and later it was lower in Group I. Parental satisfaction in Group I was higher. The number of attempts for iv cannulation and required propofol dose was less in Group I. CONCLUSION: "Multiphase sedation" procedure provides children to feel less pain and anxiety, and decreases parental anxiety while increasing their satisfaction. It supplies a comfortable and safe sedation, as it provides a short and problem-free preparation process for the attending anesthetist as well.
