自1906年 McDonald 首次描述妊娠期测量耻骨联合-宫底高度(SF)以来,虽对用其筛选小于孕龄儿(SGA)的价值有争议,但已常规地运用于产科,并为了提高其可信度,在评价的方法上有所发展,目前提出连续测量 SF,采用多次宫高值进行分析以预测 SGA,本文就此作一回顾性研究以评价其灵敏性与特异性以及对其应用确立准则。Columbia 医院于1980～1982年分娩新生儿1,800例,其中192例具有下述标准:(1)单胎妊娠;(2)初诊始于孕13周以前或孕13周(依据日期大小或孕14周以前超声图像);(3)38～41孕周分娩;(4)Apgar 评分在出生后5分钟时大于或等于7分;(5)胎儿、胎盘、脐带以及子宫无明显异常;(6)产妇无妊娠并发症及合并症。对此192例新生儿出生体重分布状态进行预测,结果
Since 1906, McDonald first described the measurement of pubic symphysis during the pregnancy - the fundus height (SF), although it is controversial on the value of screening smaller than gestational age (SGA), but has been routinely used in obstetrics and in order to improve its Reliability, the method of evaluation has been developed, the current proposed continuous measurement of SF, the use of multiple uterine heights to predict the analysis of SGA, this paper for a retrospective study to evaluate its sensitivity and specificity and its application established Guidelines. Columbia Hospital produced 1,800 newborns between 1980 and 1982, of which 192 had the following criteria: (1) singleton pregnancies; (2) first visit at 13 weeks of gestation or at 13 weeks of gestation (based on date size or 14 weeks gestation Previous ultrasound images); (3) 38 to 41 gestational weeks of childbirth; (4) Apgar score greater than or equal to 7 points at 5 minutes after birth; (5) no abnormalities in the fetus, placenta, umbilical cord and uterus; No pregnancy complications and complications. This 192 cases of newborns birth weight distribution status prediction, the results
