Abstract
This prospective, randomized, singleblind study of 121 healthy children aged 2 to 12 yr investigated the effect of clear fluids on gastric contents. Gastric fluid volume and pH were measured immediately following the induction of general anaesthesia and were not significantly affected by the ingestion of unlimited clear fluids up to three hours preoperatively. After a prolonged fast (mean fast 14 hr), gastric fluid volume was 0.39 ± 0.37ml · kg−1 and gastric pH was 1.7 ± 0.4; after unlimited clear fluids (203 ± 109 ml) up to three hours before surgery gastric fluid volume was 0.34 ± 0.28 ml · kg−1 and gastric pH was 1.8 ± 0.7 (mean ± SD). Gastric fluid volume (ml-kg−1) increased in both the control and study groups as age increased, P < 0.005. It is concluded that drinking clear fluid up to three hours before scheduled surgery does not have a measurable effect on gastric volume and pH of healthy children of âgés 2 to 12 yr. Cette étude prospective randomisée à simple insu chez 121 enfants en bonne santé âgés de 2 á 12 ans a étudié les effets de l’administration de liquide clair sur le contenu gastrique. Le volume gastrique et son pH ont ete mesures immediatement après l’induction de ianesthesie generale et n’etaient pas significativement affectés par Iingestion d’une quantité illimitée de liquide clair jusqu’ à trois heures avant la chirurgie. Après un jeûne prolongé (jeûne moyen = 14 heures), le volume du liquide gastrique était de 0,39 ± 0,37 ml · kg−1 et le pH gastrique était de 1,7 ± 0,4; après une quantité illimitee de liquide clair (203 ± 109 ml) jusqu’ à trois heures avant la chirurgie, le volume du liquide gastrique était de 0,34 ± 0,28 ml · kg−1 et le pH gastrique était de 1,8 ± 0,7 (moyenne ± SD). Le volume du liquide gastrique (ml · kg−1) augmenta tant chez le groupe contrôle que le groupe étudié en fonction de l’âge, P < 0,05. On conclut que I’ingestion de liquide clair jusqu’a trois heures avant la chirurgie n’affecte pas d’unefaccon mesurable le volume du liquide gastrique et son pH chez les enfants en bonne santé et âgés de 2 a 12 ans.This publication has 14 references indexed in Scilit:
