【摘要】 目的　探讨新生儿胃食管反流与胃排空的关系。方法　通过99mTc DTPA胃食管显像方法测定从 1 997年 1 1月到 1 999年 2月共 77例相对正常新生儿的 6 0min胃排空率和胃食管反流指数 ,其中足月儿 46例 ,早产儿 31例 ,以此了解相对正常新生儿无症状反流的发生率 ,胃食管反流与胃排空的关系。结果　足月儿无症状胃食管反流率为 6 0 .9% (2 8/4 6 ) ,早产儿达 83.9% (2 6 /31 ) ,差异有显著性。无症状反流指数平均为 6 .7%。足月儿或早产儿组中 ,有反流或无反流者 ,其胃排空率没有差异。结论　新生儿中存在一定比例的无症状胃食管反流 ,尤其是早产儿 ;未发现胃食管反流指数与胃排空率之间的相关关系。更多还原

【Abstract】 Purpose To study the relationship between neonatal gastroesophageal reflux and gastric emptying rate. Methods 99m Tc DTPA gastroesophageal scintigraphy was used to measure the neonatal gastrointestinal motility.The parameters used here were gastric emptying rate at 60 min after feeding (GE 60 %),and reflux index (RI).77 relatively normal neonates were enrolled in this study during Nov.1997 to Feb.1999. Results There was a considerably incidence of asymptom gastroesophageal reflux in 77 neonates,60.9% in 46 full term neonates and 83.9% in 31 preterm infants, P <0.05.RI was 6.7% on the average.No difference of GE 60 % was found between neonates with and without gastroesophageal reflux. Conclusions Asymptom gastroesophageal reflux existed in relatively normal neonates,especially in preterm infants.No relationship was found between gastroesophageal reflux and gastric emptying rate.更多还原
