摘　　要：目的分析不同胎龄新生儿体表胃电图的临床特点。方法收集不同胎龄新生儿的体表胃电图资料。将收入我科不同胎龄的新生儿分为4组:Ⅰ组为胎龄≥37周;Ⅱ组为胎龄34～36+6周;Ⅲ组为胎龄32～33+6周;Ⅳ组为胎龄<32周,在生后1周内进行体表胃电图检测,记录并分析胃电图参数。应用ANOVA方法对各组间的差异进行统计学分析。对其中部分早产儿在生后1周内、2、4周分别进行胃电图检测,应用配对t检验检测同一病例的胃电图参数的前后差异。结果对141例新生儿进行了胃电图检测,Ⅰ组25例;Ⅱ44例;Ⅲ组33例;Ⅳ组39例。与成人和儿童相比所有新生儿的正常胃电慢波百分比均较低,平均为30.6%,而胃电节律紊乱百分比较高。各组间正常胃电慢波百分比、胃电节律过缓百分比及胃电节律过速百分比差异无统计学意义。24例早产儿生后4周及生后2周的胃电图参数与生后1周内相比差异无统计学意义。结论与成人和儿童相比,新生儿的胃肌电活动不成熟,生后1周内不同胎龄的早产儿与足月儿的胃电形式比较,差异无统计学意义,新生儿的胃肌电活动在生后4周时仍处于发育成熟阶段。Objective To collect the electrogastrographic data of neonates in different gestational ages, and analyze the characteristics of electrogastrography of neonates in different gestational ages. Methods Neonates of different gestational ages were assigned into four study groups： Group I ： full term neonates of ≥37 weeks; Group Ⅱ ： premature neonates of 34 -36^＋6 weeks; Group m： premature neonates of 32 - 33^ ＋6 weeks; Group Ⅳ ： premature neonates of 〈 32 weeks. Electrogastrography was recorded in neonates in the first week to record and analyze the electrogastrographic data. ANOVA method was used to assess the differences in EGG data among patients from the four gestational age groups. Etectrogastrography was recorded in some premature neonates in the first week, 2nd week and the 4th week. The t-test was applied to study the differences between different periods. Results Electrogastrography was recorded in 141 neonates, Group Ⅰ ： 25 full term neonates; Group II： 44 premature neonates; Group Ⅲ ： 33 premature neonates; Group Ⅳ ： 39 premature neonates. The mean percentages of normogastria were 30. 6% in all neonates, showing much lower than the children and adults, but the percentages of gastric dysrythmia were greater. There were no significant differences in the percentages of nornlogastria, bradygastria, tachygastria and dominant frequency between different groups. Electrogastrography was recorded in the first, 2nd and the 4th week in 24 premature neonates, there were no significant differences in the electrogastrographic data between different periods. Conclusion The Electrogastrographic patterns should be similar between premature and full term neonates in the first week, and the gastric myoelectrical activity in premature and full term neonates is immature, as compared to the children and adults. Gastric myoelectrical activity of neonates in the first four weeks should be still in the developmental process.
