Fetal Hemodynamic Parameters in Low Risk Pregnancies: Doppler Velocimetry of Uterine, Umbilical, and Middle Cerebral Artery
Objective. To elaborate curves of longitudinal reference intervals of pulsatility index (PI) and systolic velocity (SV) for uterine (UtA), umbilical (UA), and middle cerebral arteries (MCA), in low risk pregnancies. Methods. Doppler velocimetric measurements of PI and SV from 63 low risk pregnant women between 16 and 41 weeks of gestational age. Means (±SD) for intervals of gestational age and ...
متن کاملComparative Study of Foetal Colour Doppler versus Non-Stress Test as a Predictor of Perinatal Outcome in High Risk Pregnancy
The desire of every women contemplating motherhood is that her pregnancy culminates in a healthy offspring who will achieve the highest possible physical and mental potential. Assessment of the foetal wellbeing is done by various biophysical methods. But the problem of sample collection, accuracy and need for laboratory technology and personnel have made biochemical methods of foetal monitoring...
متن کاملpredictive accuracy of nonstress test in high risk pregnancies
there are now several tests available that can assess fetal status. a series of 164 cases of high risk pregnancies were studied in order to assess predictive value of a nonstress test. the majority (36%) of patients complained about postdate pregnancy. a nonreactive test was identified in 24 of the patients (14.6%). fetal distress, low apgar score in 1 and 10 minutes after birth and mean of apg...
متن کاملA critical appraisal of the use of umbilical artery Doppler ultrasound in high-risk pregnancies: use of meta-analyses in evidence-based obstetrics.
OBJECTIVES To reanalyze randomized controlled trials on the use of umbilical artery Doppler velocimetry in high-risk pregnancies and determine which high-risk pregnancies benefit from the use of Doppler velocimetry. METHODS Searching Medline, the Cochrane Library and Embase we found 13 randomized controlled trials on the use of Doppler velocimetry in high-risk pregnancies. Of these, six inclu...
متن کاملEnd-diastolic Umbilical Artery Doppler Flow Velocity
Doppler velocity measurement has been extensively applied in prenatal diagnosis for more than two decades. Blood flow in numerous vessels has been investigated to predict fetal condition, especially in the umbilical artery [1–7]. Histopathologic studies suggest that abnormal umbilical artery Doppler velocimetry is correlated with a pathologic lesion of the placenta characterized by obliteration...
