Propofol is a short-acting, intravenously administered hypnotic agent which is used in procedural sedation in children. Propofol is known to decrease systemic vascular resistance, arterial blood pressure and can lead to desaturations and decreased systemic perfusion in children with cardiac shunting. This may result in a reduction in cerebral blood flow and(More)
To evaluate the relationship between the cerebral tissue oxygenation index measured by near-infrared spectroscopy and central venous oxygen saturation (SvO2) after corrective surgery of congenital heart defects in children. Prospective observational clinical study. A tertiary neonatal and paediatric intensive care unit for paediatric cardiology. Neonates(More)
To compare the cerebral tissue oxygenation index (TOI) measured by near-infrared spectroscopy (NIRS) with venous oxygen saturation in the jugular bulb (SjO2) during elective cardiac catheterization in children. Prospective observational clinical study in a catheterization laboratory for pediatric cardiology. Sixty children with congenital heart defects(More)
BACKGROUND We compared two different near-infrared spectrophotometers: cerebral tissue oxygenation index (TOI) measured by NIRO 200 and regional cerebral oxygenation index (rSO(2)) measured by INVOS 5100 with venous oxygen saturation in the jugular bulb (SjO(2)) and central SvO(2) from the superior caval vein (SVC) during elective cardiac catheterization in(More)
Sildenafil (Viagra) has been shown to be an effective pulmonary vasodilator and is increasingly used in patients with pulmonary hypertension. Its effects on the cerebral circulation are unclear and have not yet been described. We investigated the effect of i.v. sildenafil treatment on cerebral oxygenation in 13 children with elevated pulmonary vascular(More)
BACKGROUND The brain of children in the early period after repair of congenital heart defects with cardiopulmonary bypass (CPB) may be more vulnerable to hemodynamic changes because of impaired cerebral autoregulation. During postoperative testing of the external temporary safety pacer, we performed desynchronizing ventricular pacing (VVI) while monitoring(More)
OBJECTIVES Mechanical circulatory support (MCS) is a rescue therapy for infants and children suffering from severe cardiorespiratory failure with specific system-related complications like bleeding, thromboembolism and device failure. Novel circuit components for temporary MCS with improved haemodynamic properties may improve patients' outcome and reduce(More)
OBJECTIVES Device closure of atrial septal defects (ASD II) is an alternative to surgery. ASD morphology and intracardiac relationships may influence device selection. Biocompatibility, techniques for closing large or multiple defects, and the risk of erosion are main issues in children BACKGROUND The GORE® Septal Occluder (GSO) is a non-self-centering(More)
Mutations in genes encoding for desmosomal components are associated with a broad spectrum of phenotypes comprising skin and hair abnormalities and account for 45-50% of cases of arrhythmogenic right ventricular cardiomyopathy. Today, more than 120 dominant and recessive desmoplakin (DSP) gene mutations have been reported to be associated with skin, hair(More)
