The left ventricle in well newborns versus those with perinatal asphyxia, haemodynamically significant ductus arteriosus or fetal growth restriction

چکیده

: Hemodynamic changes accompanying the initial breaths at time of birth are especially important for a smooth transition fetal to neonatal circulation. Understanding normal transitional physiology and clinical impact adverse adaptation is delineating pathology so as guide physiologically relevant therapies. Disorders such severe perinatal asphyxia, hemodynamically significant patent ductus arteriosus (and its surgical ligation) utero-placental insufficiency underlying growth restriction, can adversely affect left ventricular (LV) function. The ventricle predominant chamber involved in systemic perfusion during postnatal life. Cardiac output closely linked afterload; latter determined by arterial properties stiffness compliance. This article outlines term preterm infants. It also highlights three not uncommon disorders on LV Perinatal asphyxia leads reduced output, superior vena cava coronary artery blood flow an increase troponin level. Multiple haemodynamic observed premature infant with large arteriosus. They need careful analysis determine when ligation should proceed. Ligation itself generally results dramatic afterload which may lead reduction contractility ionotropic support. Fetal restricted infants have higher systolic pressure, somewhat hypertrophied heart arising from increased wall thickness/stiffness peripheral resistance. Point care ultrasound (POCUS) helps differentiate that resulting disorders. be increasingly utilized guiding management.

B-type natriuretic peptide for assessment of haemodynamically significant patent ductus arteriosus in premature infants

AIM Haemodynamically significant patent ductus arteriosus (hsPDA) is frequently observed in premature infants. This study was conducted to explore whether the blood BNP can be a valuable biomarker to assess the necessity of treatment for hsPDA in premature infants. METHODS Serial measurements of the blood BNP were performed during the first 5 days of life in premature infants with hsPDA (Grou...

Plasma brain natriuretic peptide as a predictor of haemodynamically significant patent ductus arteriosus in preterm infants.

Patent ductus arteriosus (PDA) is an important cause of morbidity in extremely preterm infants. As increased plasma brain natriuretic peptide (BNP) is a common feature of adult cardiac disease, we investigated the value of plasma BNP concentration as a predictor of haemodynamically significant PDA in very preterm infants. We studied 18 preterm infants (12 male) of median gestational age 30 week...

Left-Sided Patent Ductus Arteriosus

W HEN there is a right-sided aortic arch, persistence of a left-sided ductus arteriosus can readily be demonstrated by angiocardiography. This is important because in some types of eyanotic congenital heart disease, such as in the tetralogy of Fallot, anl artificial aortico-pulmonary (Blalock-Taussig' or Pott S2 shunt) is often created in order to alleviate the distress produced by anoxia. Two ...

Seizure-associated brain injury in term newborns with perinatal asphyxia.

BACKGROUND There is controversy over whether seizures, the most common manifestation of neonatal brain injury, may themselves damage the developing brain. OBJECTIVE To determine if neonatal seizures are independently associated with brain injury in newborns with perinatal asphyxia. METHODS Ninety term neonates were studied with MRI and single-voxel (1)H-MRS on median day of life 6 (range 1 ...

Cyclooxygenase-2 plays a significant role in regulating the tone of the fetal lamb ductus arteriosus.

Nonselective cyclooxygenase (COX) inhibitors are potent tocolytic agents but have adverse effects on the fetal ductus arteriosus. We hypothesized that COX-2 inhibitors may not affect the ductus if the predominant COX isoform is COX-1. To examine this hypothesis, we used ductus arteriosus obtained from late-gestation fetal lambs. In contrast to our hypothesis, fetal lamb ductus arteriosus expres...
