The human brainstem is fashioned around the 6th–7th week of gestation and matures in a caudal to rostral arc, thereby forming the medulla, pons, and midbrain. The medulla mediates arousal, brea- thing, heart rate, and gross movements of the body and head, and medullary functions appear ...
BETAMETHASONE AND FETAL HEART RATE 549 There is presently no evidence that corticosteroids may deteri- orate the fetal condition. In an extensive Doppler study of fetal and uteroplacental blood flow velocity waveforms, Cohlen et al. (27) found no changes in resistance to blood flow nor signs ...
Some have argued that since Doppler appears to be applicable primarily in a population already defined as high risk, the clinical decisions as to when a fetus is distressed and requires emergent delivery will be made based on the BPP and heart rate monitoring, making the Doppler superfluous. A ...

Case 95 involved high-density umbilical cord coiling, type III esophageal atresia, irregular heart rate, reflexes, muscle tone, and respiration, and death occurred 11 days after birth. Furthermore, the accuracy of the detection of fetal DSMs using prenatal ultrasonography in 83 preserved pregnancies...
Heart rate was obtained using the pulsed Doppler mode. The variables were correlated with gestational age using Spearman's test, and the adjustment of these variables to simple and multiple regression models was done to determine the mathematical formulas for calculating the gestational age. The ...

For those fetuses diagnosed with FGR, regular assessment of fetal biometry, evaluation of amniotic fluid volume, use of the biophysical profile (BPP), Doppler US, fetal heart rate monitoring, especially the nonstress test (NST), and fetal movement counting [10] can all contribute to the determi...
(UtA PI) estimated by Doppler sonography were extracted from the database of patients who were tested at admission to the high-risk clinic with the suspected complications. The reactive hyperemia index (RHI), and the Augmentation Index (AIX%) were extracted from the patient database using ...
