HKJGOM 2009; 9 (1) 28 Introduction Fetuses born with significant growth restriction have an increased risk of adverse perinatal outcomes1. Moreover, increased perinatal morbidity and mortality was often associated with the presence of abnormal Doppler waveforms in the umbilical arteries (UAs), either in the form of absent or reversed end-diastolic flow2,3. In fetuses with abnormal umbilical art...
Renal artery thrombosis and ischaemia presenting as severe neonatal hypertension A baby boy (1460 g) was delivered at 30 weeks' gestation by caesarean section for preterm labour and fetal distress. Umbilical arterial and venous catheters were inserted between T8 and T9 briefly during the immediate postnatal period. On day 23, the baby was hypertensive (highest blood pressure 113/77 mm Hg; mean ...
This cross sectional study was carried out on 60 pregnant Bangladeshi women in the department of Radiology and Imaging, BIRDEM for measurement of Pulsatility Index (PI) of umbilical artery of their fetuses by duplex colour Doppler sonography during 2nd and 3rd trimester of pregnancies. Considering total 2nd and 3rd trimesters the mean PI value of umbilical artery was 1.24 (SD +/- 0.27). While c...
Background: Studies on physical activity during pregnancy and its impact mother fetus are still limited. International protocols consider only aerobic exercise fail to provide information about other modalities such as isometric exercise. Isometric promotes cardiorespiratory resistance muscle strengthening, but it is rarely tested pregnant women because increases maternal blood pressure can sub...
OBJECTIVE Alteration to blood flow in the maternal-foetal compartment has been proposed as a mechanism underlying maternal psychological effects on pregnancy outcomes. This study characterised the progression of umbilical and uterine blood flow resistance in healthy pregnancies and evaluated concurrent and longitudinal associations with maternal anxiety and other psychological factors. METHOD...
BACKGROUND To determine whether the phosphodiesterase type 5 inhibitor, Sildenafil citrate, affects uteroplacental perfusion. MATERIALS AND METHODS Based on a randomized double-blinded and placebo-controlled trial, forty one pregnant women with documented intrauterine growth retardation at 24-37 weeks of gestation were evaluated for the effect of a single dose of Sildenafil citrate on uteropl...
Thirty-eight healthy women undergoing elective Caesarean section under spinal anaesthesia at term were allocated randomly to receive boluses of either phenylephrine 100 micrograms or ephedrine 5 mg for maintenance of maternal arterial pressure. The indication for administration of vasopressor was a reduction in systolic pressure to < or = 90% of baseline values. Maternal arterial pressure (BP) ...
OBJECTIVE to evaluate neonatal morbidity and mortality in monochorionic-diamniotic (MCDA) twin pregnancies complicated by selective intrauterine growth restriction (sIUGR) and non-selective intrauterine growth resctriction (nsIUGR). METHODS neonatal morbidity parameters and mortality were analyzed in 34 twins with IUGR (< 10th percentile on twins' growth charts): 18 with sIUGR and 16 with nsI...
BACKGROUND: Multi-vessel Doppler ultrasonography is the principal surveillance tools in pregnancies complicated by fetal growth restriction. OBJECTIVE:To determine diagnostic accuracy of umbilical artery, middle cerebral artery pulsatility indices and their ratio intrauterine restricted fetuses. PATIENTS METHODS: Forty patients were studied that had been diagnosed clinically ultrasonographicall...
