The objective of this study was to evaluate the early changes in serial serum levels of copeptin and neuron-specific enolase (NSE) in neonates diagnosed with birth asphyxia, and to determine whether these biomarkers measured in the first 168 hours after birth are predictive of long-term neurodevelopmental outcome. Copeptin and NSE levels were measured from serum samples collected 6, 12, 24, 48, 72, and 168 hours after birth from 75 term neonates diagnosed with hypoxic-ischemic encephalopathy (HIE) and treated with therapeutic hypothermia for 72 hours...

Ex vivo uterine environment (EVE) therapy is an experimental neonatal intensive care strategy wherein gas exchange is performed by membranous oxygenators attached to the umbilical vessels. Our aim was to assess the ability of a newly refined EVE system to maintain key physiological parameters in preterm lambs within optimal ranges for 48 h. EVE group; n = 6: Preterm lambs were delivered under general anesthesia at 115 ± 2 days of gestational age. Animals were submerged in a bath of artificial amniotic fluid on EVE therapy for 48 h...

The lack of donor organs has led to the development of alternative "destination therapies", such as a bio-artificial lung (BA) for end-stage lung disease. Ultimately aiming at a fully implantable BA, general capabilities and limitations of different oxygenators were tested based on the model of BA positioning at the right upper lobe. Three different-sized oxygenators (neonatal, paediatric, and adult) were tested in a mock circulation loop regarding oxygenation and decarboxylation capacities for three respiratory pathologies...

Neonates suffering from pulmonary hypertension of the newborn (PPHN) continue to represent an important proportion of patients requiring intensive neonatal care, and have an increased risk of morbidity and mortality. The human fetus has evolved to maintain a high pulmonary vascular resistance (PVR) in utero to allow the majority of the fetal circulation to bypass the lungs, which do not participate in gas exchange, towards the low resistance placenta. At birth, oxygen plays a major role in decreasing PVR to enhance pulmonary blood flow and establish the lungs as the organ of gas exchange...

Neonatal period represents first 28 days of life, which is the most vulnerable time for a child's survival especially for the preterm babies. High neonatal mortality is a prominent and persistent problem across the globe. Non-availability of trained staff and infrastructure are the major recognized hurdles in the quality care of these neonates. Hourly progress growth charts and reports are still maintained manually by nurses along with continuous calculation of drug dosage and nutrition as per the changing weight of the baby...

BACKGROUND: Carbon-dioxide elimination during high-frequency oscillatory ventilation (HFOV) is thought to be proportional to the carbon dioxide diffusion coefficient (DCO2 ) which is calculated as frequency x (tidal volume)(2) . DCO2 can be used to as an indicator of CO2 elimination but values obtained in different patients cannot be directly compared. OBJECTIVES: To analyze the relationship between DCO2 , the weight-corrected DCO2 (DCO2 corr) and blood gas PCO2 values obtained from infants receiving HFOV...

BACKGROUND: The use of norepinephrine for maintaining blood pressure (BP) during spinal anesthesia for cesarean delivery has been described recently. However, its administration by titrated manually controlled infusion in this context has not been evaluated. METHODS: In a double-blinded, randomized controlled trial, 110 healthy women having spinal anesthesia for elective cesarean delivery were randomly allocated to 1 of 2 groups. In group 1, patients received an infusion of 5 μg/mL norepinephrine that was started at 30 mL/h (2...

BACKGROUND: Extremely preterm infants born at the border of viability (22-24 weeks' gestation) have high rates of death and lasting disability. Ex vivo uterine environment therapy is an experimental neonatal intensive care strategy that provides gas exchange using parallel membranous oxygenators connected to the umbilical vessels, sparing the extremely preterm cardiopulmonary system from ventilation-derived injury. OBJECTIVE: In this study, we aimed to refine our ex vivo uterine environment therapy platform to eliminate fetal infection and inflammation, while simultaneously extending the duration of hemodynamically stable ex vivo uterine environment therapy to 1 week...

INTRODUCTION: Nasal high-flow (nHF) therapy is a popular mode of respiratory support for newborn infants. Evidence for nHF use is predominantly from neonatal intensive care units (NICUs). There are no randomised trials of nHF use in non-tertiary special care nurseries (SCNs). We hypothesise that nHF is non-inferior to nasal continuous positive airway pressure (CPAP) as primary support for newborn infants with respiratory distress, in the population cared for in non-tertiary SCNs. METHODS AND ANALYSIS: The HUNTER trial is an unblinded Australian multicentre, randomised, non-inferiority trial...

BACKGROUND: Docosahexaenoic (C22:6) and arachidonic (C20:4) acids are long-chain polyunsaturated fatty acids (LC-PUFA) essential to neonatal development, being present in the glycerophospholipids of all organs, particularly the brain. In plasma, LC-PUFAs are mainly present in lipoprotein lipids, which are neutral lipids (triglycerides and cholesterol esters) and glycerophospholipids, like choline containing phosphatidylcholine (PC). PURPOSE: To guide future supplementation strategies of C22:6 and C20:4 in combination with choline, we determined the distribution of C20:4 and C22:6 between PC and neutral lipid...

Although the effects of antenatal corticosteroid therapy in clinical improvement and pulmonary maturation in preterm have been described, little is known on premature newborn puppies. This study aimed to evaluate the effect of maternal administration of a single dose of prenatal betamethasone on lung function of preterm newborn puppies in the first hours of life, especially from the clinical point of view and acid-base balance. A prospective study was conducted involving 21 puppies allocated into three experimental groups: Term Group (63 days post-ovulation), Preterm-Treated Group (57 days post-ovulation and maternal administration of a single dose of 0...

Vasantha Hs Kumar, Annie Skrobacz, Changxing Ma
BACKGROUND: Fetal hypoxia from intrapartum events can lead to absent heart rate (HR) or bradycardia at birth requiring aggressive neonatal resuscitation. Neonatal resuscitation guidelines do not differentiate bradycardia (HR <100 beats/min) from absent HR at birth. Given that HR is the primary determinant of resuscitation, we hypothesize that infants with no HR at 1 min would require more extensive resuscitation with worse clinical outcome than infants with bradycardia at 1 min. METHODS: A retrospective analysis was performed in infants born between 1 January 2000 and 31 December 2015 with no HR at 1 min (defined as Apgar score [AS] = 0 at 1 min; absent HR [AHR] group) or bradycardia at 1 min (AS = 1 at 1 min)...

PURPOSE: Current knowledge about pulmonary/systemic hemodynamics and gas exchange during neonatal resuscitation in a model of transitioning fetal circulation with fetal shunts and fluid-filled alveoli is limited. Using a fetal lamb asphyxia model, we sought to determine whether hemodynamic or gas-exchange parameters predicted successful return of spontaneous circulation (ROSC). METHODS: The umbilical cord was occluded in 22 lambs to induce asphyxial cardiac arrest...

In the developed world, extreme prematurity is the leading cause of neonatal mortality and morbidity due to a combination of organ immaturity and iatrogenic injury. Until now, efforts to extend gestation using extracorporeal systems have achieved limited success. Here we report the development of a system that incorporates a pumpless oxygenator circuit connected to the fetus of a lamb via an umbilical cord interface that is maintained within a closed 'amniotic fluid' circuit that closely reproduces the environment of the womb...

BACKGROUND: The pneumatic tube system (PTS) is commonly used in modern clinical laboratories to provide quick specimen delivery. However, its impact on sample integrity and laboratory testing results are still debatable. In addition, each PTS installation and configuration is unique to its institution. We sought to validate our Swisslog PTS by comparing routine chemistry, hematology, coagulation and blood gas test results and sample integrity indices between duplicate samples transported either manually or by PTS...
