Resumo

JUSTIFICATIVA E OBJETIVOS: Freqüentemente, crianças com refluxo gastroesofágico têm que ser submetidas a anestesia para estudos diagnósticos e/ou procedimentos cirúrgicos. Considera-se que o esvaziamento gástrico seja retardado na doença do refluxo gastroesofágico pediátrico. Portanto, a anestesia nesses pacientes tem aspectos peculiares, especialmente no que se refere ao risco de aspiração pulmonar. O objetivo deste estudo é comparar o volume gástrico residual de crianças com ou sem refluxo gastroesofágico e determinar se as crianças com refluxo têm, de fato, risco aumentado para a aspiração pulmonar do conteúdo gástrico durante a anestesia. MÉTODO: Participaram do estudo 38 crianças, estado físico ASA I ou II, submetidas à endoscopia digestiva alta diagnóstica. As crianças foram divididas em dois grupos: grupo R, portadoras de refluxo gastroesofágico e grupo N, sem refluxo gastroesofágico com endoscopia digestiva alta normal. Durante o procedimento, todo o conteúdo gástrico foi aspirado e seu volume medido. RESULTADOS: Das 38 crianças estudadas, 18 (47%) foram incluídas no grupo R e 20 (53%) no grupo N. Não foram constatadas diferenças significativas entre os dois grupos no que se refere à idade, ao peso e tempo de jejum. Em todos os pacientes, o volume gástrico residual observado foi inferior a 0,4 ml.kg-1; e não houve diferenças significativas entre os grupos. CONCLUSÕES: Nas condições deste estudo, o volume gástrico residual não diferiu entre as crianças portadoras, ou não, de refluxo gastroesofágico. Portanto, as crianças com refluxo gastroesofágico não apresentaram risco aumentado de aspiração pulmonar, quando comparadas a crianças sem refluxo gastroesofágico, podendo-se dispensar sua profilaxia.

Abstract

BACKGROUND AND OBJECTIVES: Children with gastroesophageal reflux are often submitted to anesthesia for both diagnostic and therapeutic procedures. They are considered as having delayed gastric emptying and so anesthesia in this group is surrounded by special consideration, mostly with regard to pulmonary aspiration. This study aimed at comparing residual gastric volume of children with and without gastroesophageal reflux and at determining if children with gastroesophageal reflux are at risk for pulmonary aspiration during anesthesia.
METHODS: Participated in this study 38 children, physical status ASA I and II undergoing upper digestive diagnostic endoscopy. Children were distributed in two groups, according to the presence (group R) or absence (group N) of gastroesophageal reflux. All gastric content was collected and measured during the procedure.
RESULTS: There were 18 (47%) group R children and 20 (53%) group N children. Age, weight and fasting time were not significantly different between groups. In all patients, residual gastric volume was less then 0,4 ml.kg-1 and there were no significant differences between groups.
CONCLUSIONS: Children with gastroesophageal reflux were not at increased risk for pulmonary aspiration, as compared to children without reflux. Therefore, its prophylaxis would not be necessary.
