In a study involving 25 preterm infants, obstetric clinical age (standard gestational age) was determined by history, physical examination, and ultrasonographic evaluation. Postnatally, these infants were then evaluated using the Dubowitz Scoring System (DSS) for gestational age assessment. The DSS, as administered by us, significantly overestimated gestational age compared with the standard gestational age (mean +/- 1 SD: 34.2 +/- 2.9 vs 32.5 +/- 3.9 weeks, respectively) in preterm infants. To illustrate, the gestational ages of 13 newborns (52%) in the total study group were each overestimated by more than two weeks. This percentage increased to 75% among the 16 infants whose gestational ages were less than 34 weeks (by standard gestational age). When the standard gestational age was underestimated by the DSS, this difference never exceeded two weeks. These findings suggest that the present system of postnatal assessment of gestational age in preterm infants needs further investigation.
在一项涉及25名早产儿的研究中,通过病史、体格检查和超声评估来确定产科临床年龄(标准胎龄)。出生后,然后使用杜波维茨评分系统(DSS)对这些婴儿进行胎龄评估。由我们实施的DSS在早产儿中与标准胎龄相比显著高估了胎龄(平均值±1标准差:分别为34.2±2.9周和32.5±3.9周)。举例来说,在整个研究组中,13名新生儿(52%)的胎龄被高估了两周以上。在胎龄小于34周(按标准胎龄)的16名婴儿中,这一比例增至75%。当DSS低估标准胎龄时,这种差异从未超过两周。这些发现表明,目前早产儿出生后胎龄评估系统需要进一步研究。
