Sonographic Determination of Gestational Age
The Ultrasound Review of Obstetrics and Gynecology, 2005Appropriate assessment of gestational age is paramount in obstetric care. Making appropriate management decisions requires accurate appraisal of gestational age. Accurate pregnancy dating may assist obstetricians in appropriately counseling women who are at risk of a preterm delivery about likely neonatal outcomes and is also essential in the ...

The Dubowitz Assessment of Gestational Age
Physical & Occupational Therapy In Pediatrics, 1983An annotated bibliography of research related to the Dubowitz Assessment of Gestational Age is presented. The introduction explains the usefulness of the Dubowitz system as a tool to assess gestational age and the need for such an assessment. Materials reviewed include descriptive literature and a videotape of the evaluation, studies which compare the ...

Ultrasound Estimation of Gestational Age
Clinical Obstetrics and Gynecology, 1984Many ultrasonologists feel that if they are unable to obtain a BPD measurement at the time of an ultrasound examination that they have somehow failed to do an adequate job. However, from the information outlined in this chapter, it can be seen that the biparietal diameter is only one measurement that can be taken of the fetus in order to estimate ...

Twin gestation: Fetal presentation as a function of gestational age
American Journal of Obstetrics and Gynecology, 1993Our objective in this study was to evaluate the rate of spontaneous version in twin gestation throughout the third trimester.Serial ultrasonographic examinations were performed on 119 consecutive patients with twin gestation. The incidence of spontaneous version as a function of gestational age was calculated.The mean birth weight and gestational age ...

Gestational age at delivery and perinatal outcomes of twin gestations
American Journal of Obstetrics and Gynecology, 2012The optimal gestational duration for twin gestations is unknown. Epidemiologic studies show that the lowest perinatal mortality rate for twins is at 37-38 weeks, but these studies lack information on pregnancy complications and neonatal morbidities. This study evaluates pregnancy characteristics and perinatal outcomes of twins in order to assess the ...

Objective. To evaluate the consequences of being small-for-gestational age at extremely low gestational age. Methodology. Comparison of two historical cohorts of small-for-gestational age (SGA) and appropriate-for-gestational age (AGA) infants born between 24 and 26 6/7 weeks of gestation (gestational age estimated by early ultrasound at

Birthweight‐for‐gestational age charts based on early ultrasound estimation of gestational age
BJOG: An International Journal of Obstetrics & Gynaecology, 1986Summary. Birthweight‐for‐gestational age charts were based on the analysis of 3888 consecutive births in which the gestational age was estimated by measuring the fetal biparietal diameter before the 20th week of gestation. The data showed, in contrast to previous studies, a linear relation between gestational age and birthweight without inflection ...

Assessment of gestational age and neuromaturation
Mental Retardation and Developmental Disabilities Research Reviews, 2005AbstractNeuromaturation is the functional development of the central nervous system (CNS). It is by its very nature a dynamic process, a continuous interaction between the genome and first the intrauterine environment, then the extrauterine environment.
