早产儿及胎儿胼胝体超声测量比较

目的:比较不同方式测量胎儿及早产儿胼胝体前后径的差异。方法:282例孕28～36周胎儿及222例出生孕周为28～36周的早产儿,分为胎儿组及早产儿组,胎儿组使用超声经母体腹部测量胼胝体前后径,早产儿组在出生当天使用超声经新生儿颅脑测量胼胝体前后径。比较两种方式测量胼胝体前后径的差异。结果:孕28～36周胎儿胼胝体前后径分别为:(34.56±1.27)mm、(35.53±1.30)mm、(37.66±1.41)mm、(37.11±1.53)mm、(38.54±1.99)mm、(38.20±1.07)mm、(39.53±2.13)mm、(42.59±1.57)mm、(43.56±2.31)mm;出生孕周为28～36周的早产儿胼胝体前后径分别为(33.50±1.67)mm、(34.14±2.01)mm、(36.50±1.21)mm、(36.69±1.45)mm、(37.68±2.04)mm、(38.36±1.97)mm、(38.62±1.34)mm、(40.54±1.57)mm、(42.94±2.11)mm。胎儿组经母体腹部测量胼胝体前后径与相同孕周出生早产儿出生当天经颅脑超声测量胼胝体前后径差异无统计学意义(P>0.05)。结论:经母体腹部与经新生儿颅脑两种方式测量胼胝体前后径差异无统计学意义(P>0.05)。胎儿胼胝体生长发育数据可以作为早产儿宫外胼胝体生长发育的对照参考。

Comparison of corpus callosum measured by ultrasound between premature infants and fetuses

Objective:To compare the differences of anteroposterior diameter of corpus callosum measured by different methods between premature infants and fetuses.Methods:282 fetuses of 28~36 gestational weeks and 222 premature infants of 28~36 gestational weeks were selected as fetal group and premature infants group,respectively;the anteroposterior diameters of corpus callosum in fetal group were measured by maternal transabdominal ultrasound,and the anteroposterior diameters of corpus callosum in premature infants group were measured by neonatal transcranial ultrasound on the day of birth;the differences of anteroposterior diameter of corpus callosum measured by the two methods were compared.Results:The anteroposterior diameters of corpus callosum in fetal group of 28~36 gestational weeks were(34.56±1.27)mm,(35.53±1.30)mm,(37.66±1.41)mm,(37.11±1.53)mm,(38.54±1.99)mm,(38.20±1.07)mm,(39.53±2.13)mm,(42.59±1.57)mm and(43.56±2.31)mm,respectively;the anteroposterior diameters of corpus callosum in premature infants group of 28~36 gestational weeks were(33.50±1.67)mm,(34.14±2.01)mm,(36.50±1.21)mm,(36.69±1.45)mm,(37.68±2.04)mm,(38.36±1.97)mm,(38.62±1.34)mm,(40.54±1.57)mm and(42.94±2.11)mm,respectively;there was no significant difference in anteroposterior diameter of corpus callosum between fetal group and premature infants group(P>0.05).Conclusion:There is no significant difference in anteroposterior diameter of corpus callosum measured by maternal transabdominal ultrasound and neonatal transcranial ultrasound;the data of growth and development of corpus callosum can be used as reference of growth and development of corpus callosum in premature infants after birth.
