Gastric Myoelectrical Activity of Neonatal Asphyxia / 中华围产医学杂志

ABSTRACT

Objective To investigate the effect of asphyxia on newborn's gastric myoelectrical activity by electrogastrography (EGG). Methods Twenty four asphyxia newborns (mild and severe type) and 15 normal newborns were enrolled. Electrogastric activity were recorded by a Portable EGG. The recording were performed 30 minutes before and after feeding respectively Results Compared with normal control,bradygastria (4 cpm) increased significantly ( P 0.01). Conclusions (1)By the help of EGG, we can get information about gastric myoelectrical activity in neonatal asphyxia.(2)Bradygastria is more prominent before feeding in mild asphyxia group; Slow wave is decreased in severe asphyxia group than that of control and mild asphyxia, but tachygastria increases significantly. This kind of abnormal electrogastric rhythm may contribute to feeding difficulty, abdominal distension and vomiting in asphyxia newborns.
