摘要
目的 利用胃电图探讨窒息对新生儿胃电活动的影响。 方法 采用瑞典 CTd-synec-tics公司生产的便携式胃电图 ( EGG)记录仪对 50例窒息后新生儿和 2 0例正常新生儿进行了喂奶前、后各 3 0 min的胃电活动的检测 ,利用计算机 EGG Version6.4 0软件分析系统分析数据。 结果 70例新生儿有 3 9例 ( 56% )成功记录到 EGG。轻度窒息组与对照组比较 ,喂奶前胃动过缓 ( <2cpm)百分比增多 ( 7.0± 6.8与 4 .7± 5.4 ) ,差异有非常显著意义 ( P<0 .0 1 )。重度窒息组与对照组及轻度窒息组比较 :喂奶前、后正常慢波百分比明显降低 ( P<0 .0 1 ) ,胃动过速 ( >4 cpm)百分比明显增多 ( P<0 .0 1 )。主功频率不稳定系数 ( DFIC)增高 ( P<0 .0 1 )。 结论 EGG可以用来研究窒息后新生儿的胃电活动 ,进而研究新生儿消化道动力 ;围产期轻度窒息新生儿喂奶前胃动过缓增多 ,重度窒息新生儿喂奶前、后正常慢波百分比明显降低 ,胃动过速百分比明显增多 ,提示围产期窒息的新生儿出现拒乳、腹胀、呕吐等症状 ,可能与其胃电节律异常有关。
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 (<2 cpm) in mild asphyxia was significantly increased(7.0 vs 4.7, P <0.01),but the slow wave in severe group decreased ( P <0.01). The tachygastria (>4 cpm) increased significantly ( P <0.01),the Dominant frequency instability coefficient (DFIC) was higher than that of control ( P <0.01) Comparcd with mild asphyxia, the slow waves was significantly less in severe one ( P <0.01), tachygastria was obviously more often recorded ( 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.
