ABSTRACT
Objective To evaluate the value of ultrasonographic measurement of the antral crosssectional area (CSA) in assessing the preoperative gastric content volume in preschool pediatric patients.Methods Fifty American Society of Anesthesiologists physical status Ⅰ or Ⅱ pediatric patients of both sexes,aged <7 yr,undergoing elective non-gastrointestinal surgery,were fasted according to the preoperative fasting guidelines recommended by American Society of Anesthesiologists.Sedation was performed with intravenously injected midazolam or with intravenously injected midazolam and propofol after admission to the operating room.The antral CSA in the supine and right lateral decubitus positions was measured using bedside ultrasonography and free tracing method.A gastric tube was inserted after gastric sonography to collect the gastric fluid,and the total volume of the gastric fluid was considered to be the gastric content volume.Results Six pediatric patients were excluded due to the unsatisfactory ultrasound image,and 44 pediatric patients were included.Gastric content volume and gastric content volume per kilogram of body weight were positively correlated with the antral CSA in the right lateral decubitus position,and the Spearman correlation coefficients were 0.48 (P<0.01) and 0.37 (P<0.05),respectively.There was no correlation between gastric content volume and gastric content volume per kilogram of body weight and the antral CSA in the supine position (P>0.05).Conclusion Ultrasonographic measurement of the antral CSA in the right lateral decubitus position can be used to assess the preoperative gastric content volume in preschool pediatric patients.
