A catheter inserted in the umbilical artery with its tip in the aorta provides a convenient means for obtaining arterial blood samples, measuring pressure, and infusing fluids and drugs. Although these catheters often seem necessary to guide the treatment of newborn infants who have cardiopulmonary disease, they are dangerous. They are associated with thrombi, emboli, and infection. Their presence provokes vascular constriction and invites the infusion of vasoactive substances. Some catheter complications can be catastrophic. Recent reports include cases of hypertension,1 paraplegia,2 and septic osteoarthritis.3 In the past two years we have seen gangrene of a foot, a leg, and the lower half of the body.

The article presents the predictors of placental dysfunction on the early stage of pregnancy. The objective: the search for prognostic markers and criteria for the occurrence of placental insufficiency in the early stages of the gestational process to optimize the pregnancy and labor with improved perinatal outcomes. Patients and methods. To solve this goal in the period from 2013 to 2015 were conducted a comprehensive survey of 334 pregnant women, which depending on the peculiarities of pregnancy and childbirth were divided into groups. The control group consisted of 236 pregnant women with uncomplicated gestational period, no morphological signs of placental dysfunction. The study group included 98 patients with a complicated pregnancy who had revealed violations of the fetal-placental relations, which was confirmed by morphological examination of the placenta in the postpartum period. Results. It was found that pregnant women with placental insufficiency in the first trimester of pregnancy have higher levels of interleukin-1B (IL-1v) and interleukin-3 (IL-3) in comparison with physiological pregnancy, as well as there is a direct significant correlation between IL-1v and pulsative index (PI) in the spiral (r=0.84) and uterine artery (r=0.77), and the inverse correlation between the level of IL-3 and PI in the terminal branches of the umbilical artery (r=-0.69). Verified an inverse relationship between the concentration of endothelin-1, the level of vascular endothelial growth factor (r=-0.87) and placental growth factor (r=-0.73), and also a direct link between the content of endothelin-1 and PI in spiral arteries (r=0.89), uterine artery (r=0.83) and the terminal branches of the umbilical artery (r=0.79). Conclusion. Thus, it is proven that early predictors of placental dysfunction can be considered the concentration of endothelin-1, vascular endothelial growth factor, placental growth factor, interleukin-1, interleukin-3, and the indices of pulsative index. Key words: placental dysfunction, predictors, endothelin-1, vascular endothelial growth factor, placental growth factor, interleukin, pulsative index.

Background: Assessment of fetal health plays the most important role in prenatal care because of influence of the prediction of gestational outcome. One of the main aims of routine antenatal care is to identify the ‘ at risk ‘ fetus in order to apply clinical interventions which could results in reduced perinatal morbidity and mortality. Doppler ultrasound is a non invasive technique whereby the movement of blood is studied by detecting the change in frequence of reflected sound, Doppler blood flow velocity waves form of fetal side (umbilical artery, middle cerebral artery ...) and maternal side ( uterine arteries) are discussed and monograms for routine practice are presented. Recently this method is important tool for qualifying high risk pregnancies and help early forecasts the health of the babies and mothers disorder. Doppler sonography in obstetrics is a widely accepted functional method of examining the prediction of gestational outcome. Key words: Doppler, umbilical artery, middle cerebral artery, uterine arteries

Background: This study was aimed to evaluate the effect of sildenafil citrate on Doppler velocity indices in patients with fetal growth restriction (FGR) associated with impaired placental circulation.Methods: A double-blinded, parallel group randomized clinical trial (clinicaltrials.gov NCT02590536) was conducted in Ain Shams Maternity Hospital, in the period between October 2015 and June 2017. Ninety pregnant women with documented intrauterine growth retardation at 24-37 weeks of gestation were randomized to either sildenafil citrate 25 mg orally every 8 hours or placebo visually-identical placebo tablets with the same regimen. The primary outcome of the study was the change in umbilical artery and fetal middle cerebral artery indices.Results: There was a significant improvement in umbilical and middle cerebral artery indices after sildenafil administration p<0.001. Present study observed that, sildenafil group, in comparison to placebo, has a significantly higher mean neonatal birth weight. 1783±241g vs 1570±455g (p<0.001). There was a significantly higher mean gestational age at delivery in women in sildenafil group 35.3±1.67 weeks, whereas it was lower in the placebo group 33.5±1.7 weeks. The side effects as headache, palpitation and facial flushing were significantly higher in sildenafil group compared to placebo group.Conclusions: The use sildenafil citrate in pregnancies with fetal growth restriction (FGR) improved the feto-placental Doppler indices (pulsatility index of umbilical artery and middle cerebral artery) and improved neonatal outcomes.

Doppler examination of the umbilical artery and the fetal middle cerebral artery is evaluated predominantly in pregnancies with fetuses in cephalic presentation and never has been elucidated in breech presentation. Evidence on the accuracy of fetal weight estimation in dependence of the fetal presentation is controversial. Nevertheless, clinical decisions including recommendations for a cesarean section or labor induction based on these examinations are applied to pregnancies with fetuses in breech presentation. The objective of this study was to investigate the influence of the fetal presentation on fetal weight estimation accuracy, umbilical artery and middle cerebral artery resistance indices (RI) in a prospective case control study. Ultrasound examinations in 305 uncomplicated term pregnancies (153 vertex presentations, 152 breech) were investigated. Non-parametric variables were compared using Pearson’s chi2 test and Wilcoxon chi2 test, depending on variable scaling. Fetal weight estimation accuracy was not significantly different between vertex presentation group (VP) (6.97%) and breech presentation group (BP) (7.96%, p = 0.099). Fetal head circumference measurements were significantly larger in BP (350 mm vs. 341 mm in VB, p > 0.0001) while abdominal circumferences were significantly smaller (VP: 338 mm, BP: 331 mm, p = 0.0039) and weight estimation was not significantly different. Umbilical artery RIs were not significantly different between VP (54.5) and BP (55.3, p = 0.354). Fetal middle cerebral artery RIs also showed no significant differences (VP: 71.2, BP: 70.7, p = 0.335). Our study shows that fetal Doppler (RI) and weight estimation ultrasound originally calibrated in cephalic pregnancies are applicable to pregnancies with fetuses in breech presentation.
