: Neonatologists have begun using superior vena cava flow as assessed by functional echocardiography to facilitate real-time decision making on cardiovascular care. This review aims to describe the basis of the technique, summarise the evidence for its use and compare the technique to existing clinical, biochemical and radiological techniques for assessing neonatal circulatory status. CONCLUSION: Although echocardiographic measurements of superior vena cava flow, like other measures of perfusion, are not perfect, their non-invasive nature and ability to facilitate real-time decision making means that at present they remain the best available methodology of monitoring central perfusion in the neonatal population...

OBJECTIVE: To assess accuracy and repeatability of a modified echocardiographic approach to quantify superior vena cava (SVC) flow volume that uses a short-axis view to directly measure SVC area and a suprasternal view to measure flow velocity, both at the level of the right pulmonary artery. SETTING: Three tertiary-level neonatal intensive care units. DESIGN: This was a multicentre, prospective, observational study. Accuracy of the traditional and modified approach was first assessed by comparing echo measurements according to both techniques with Phase contrast MRI (PCMRI) assessments, in a cohort of 10 neonates...

Echocardiography in the neonatal intensive care unit has led to improvements in our ability to assess the neonatal heart in health and disease. Advances in neonatal cardiac imaging have provided the capability to obtain quantitative information that often supersedes the qualitative information provided by conventional methods. Novel quantitative measures of function include the assessment of the velocity of muscle tissue movement during systole and diastole using tissue Doppler velocity imaging, and evaluation of deformation and rotational characteristics of the myocardium utilizing speckle tracking echocardiography or tissue Doppler-derived strain imaging...

OBJECTIVES: In the progression of severe sepsis, sepsis-induced myocardial dysfunction contributes to severity of illness and ultimate mortality. Identification of sepsis-induced myocardial dysfunction causing depressed cardiac function during critical illness has implications for ongoing patient management. However, assessing pediatric cardiac function traditionally relies on echocardiographic qualitative assessment and measurement of left ventricular ejection fraction or fractional shortening...

AIM: Fetoplacental Doppler abnormalities have been associated with increased neonatal mortality and morbidity. This study evaluated the associations between prenatal Doppler assessments and neonatal mortality and morbidity in premature infants born small for gestational age or after pre-eclampsia. METHODS: This was a population-based study of infants born alive at 22(0) -33(6) weeks of gestation, a birthweight <10th percentile for gestational age and/or maternal pre-eclampsia...

BACKGROUND: As survival and outcomes continue to improve in neonates born prematurely, there is an increasing need to promptly identify and treat pulmonary hypertension (PHT) in this population. Several echocardiographic indices have been used to evaluate for PHT. There is no clear consensus on how to utilize these parameters specifically for the evaluation of PHT in infants with chronic lung disease of prematurity. OBJECTIVES: Τhe objectives of the study were (1) to identify the different echocardiographic techniques for assessment of PHT in infants with chronic lung disease of prematurity in an evidence-based manner and (2) to establish an echocardiographic screening protocol based on available literature using different echocardiographic techniques...

Germinal matrix-intraventricular haemorrhage (GMH-IVH) remains a serious problem in the very and extremely preterm infant. This article reviews current methods of diagnosis, treatment and neurodevelopmental outcome in preterm infants with low-grade and severe GMH-IVH. We conclude that there is still no consensus on timing of intervention and treatment of infants with GMH-IVH, whether or not complicated by post-haemorrhagic ventricular dilatation. The discrepancies between the studies underline the need for international collaboration to define the optimal strategy for these infants...

OBJECTIVES: Clinicians are increasingly using cardiac sonography in clinical practice. The objectives of this study were to assess the current state of clinician-performed cardiac sonography practice in the Australia-New Zealand region, with particular reference to the scope of clinical practice and type of training offered. METHODS: A prospective cross-sectional survey was conducted, and an electronic Web-based questionnaire was e-mailed to neonatologists and advanced trainees in the region...

OBJECTIVE: To investigate the effect of targeted neonatal echocardiography (TnEcho) on heart rate, arterial oxygen saturation (SPO2), cerebral regional oxygen saturation (CrSO2) and cerebral fractional oxygen extraction (CFOE) in extremely preterm infants during the first 3 postnatal days. STUDY DESIGN: s a nested study in a prospective observational study, we acquired continuous data on heart rate, SPO2, CrSO2 and CFOE. Data averaged for the duration of TnEcho study were compared with the data collected during a baseline period immediately before the start of echocardiography...

BACKGROUND: Early respiratory management of very low birth weight infants has changed over recent years to a practice of early use of CPAP with early selective surfactant administration, and decreased use of mechanical ventilation. One strategy is to use the combination of surfactant and prompt extubation to nasal continuous positive airway pressure (INtubate, SURfactant, Extubate, or INSURE). The aim of this study is to describe blood flow and ductal flow in a prospective cohort during the transitional period when this respiratory management strategy is used...

BACKGROUND: Lung ultrasound (LUS) is a promising technique for the diagnosis of neonatal respiratory diseases. Preliminary data has shown a good sensitivity and specificity of LUS in the diagnosis of respiratory distress syndrome (RDS) and transient tachypnea of the newborn (TTN). OBJECTIVE: The aim of this study was to calculate the sensitivity, specificity, and negative (NPV) and positive predictive value (PPV) of LUS for RDS and TTN, using an external reader blinded to the clinical condition...
