摘　　要：目的探讨床旁超声在早期新生儿脊髓和椎管发育中的临床价值。方法收集2022年1月—8月兰州大学第二医院125例新生儿的临床资料,包括母亲的分娩次数、分娩方式、新生儿的胎龄、性别、出生天数、身高、体重、头围、胸围,并用床旁超声测量颈、胸、腰椎脊髓和椎管前后径。按其胎龄分为早产儿组(32~36^(+6)周,30例)、早期足月儿组(37~38^(+6)周,39例)和完全足月儿组(39~40^(+6)周,56例)。比较脊髓和椎管前后径的组间差异及与临床资料的相关性,进一步观察脊髓和椎管前后径随胎龄变化的规律。结果完全足月儿组、早期足月儿组的脊髓和椎管前后径均大于早产儿组(P<0.05)。早期新生儿的脊髓和椎管前后径与胎龄、身高、体重、头围、胸围呈正相关,尤其早产儿组与胎龄明显相关(P<0.05)。脊髓和椎管发育无性别差异。结论床旁超声可以显示早期新生儿的脊髓和椎管前后径随胎龄而变化,其参考值将有助于评估新生儿的脊髓损伤。Objective To investigate the application of bedside ultrasound in evaluating the development of early neonatal spinal cord and spinal canal.Methods Clinical data of 125 newborns in the Second Hospital of Lanzhou University from January 2022 to August 2022 were collected,including maternal delivery times,delivery methods,gestational age,sex,days of birth,height,weight,head circumference and chest circumference.The cervical,thoracic,lumbar spinal cord and anterior and posterior diameter of spinal canal were measured by bedside ultrasound.According to their gestational age,they were divided into preterm infants group(32~36^(+6) weeks,30 cases),early term infants group(37~38^(+6) weeks,39 cases)and full term infants group(39~40^(+6) weeks,56 cases).The difference of spinal cord and spinal canal diameter between groups and its correlation with clinical data were compared,and the regularity of spinal cord and spinal canal diameter with gestational age was further observed.Results The anteroposterior diameters of the spinal cord and spinal canal in full term infants group and early term infants group were higher than that in the preterm infants group(P<0.05).The anteroposterior diameters of early neonatal spinal cord and spinal canal were positively associated with gestational age,height,weight,head circumference and chest circumference,especially were significantly associated with gestational age in the preterm infants group(P<0.05).No gender differences were found in the development of the spinal cord and spinal canal.Conclusion Bedside ultrasound can show the anteroposterior diameters of spinal cord and spinal canal varies with gestational age,the utility of reference values for spinal cord anteroposterior diameter in newborns is in the assessment of spinal cord injury.
