Direct Observational Study of Interfaced Smart-Pumps in Pediatric Intensive Care.

Background: Processes for delivery of high-risk infusions in pediatric intensive care units (PICUs) are complex. Standard concentration infusions (SCIs), smart-pumps, and electronic prescribing are recommended medication error reduction strategies. Implementation rates in Europe lag behind those in the United States.

The emergence of a change in the prevalence of preeclampsia in a tertiary maternity unit (2004-2016).

Background: Pre-eclampsia (PET) affects 2-3% of all pregnancies, rising to 5-7% in nulliparous women. This study aimed to investigate the prevalence of PET over a 13-year period.

Methods: A retrospective review was performed over a 13-year period (2004-2016) via interrogation of the annual clinical reports of The Rotunda Hospital, Dublin.

Intrapartum uterine activity and neonatal outcomes: a systematic review.

Background: Increased uterine activity (UA) may not allow adequate recovery time for foetal oxygenation.

Methods: The aim of the study was to determine if increased UA during labour is associated with an increased risk of either short- or long-term neurological injury in term neonates, or with neonatal proxy measures of intrapartum hypoxia-ischemia. MEDLINE, CINAHL, and ClinicalTrials.

Clinical Trials in Hemodynamic Support: Past, Present, and Future.

Managing low blood flow states in the preterm population remains a challenge in neonatal clinical care. The heterogeneity of the trials to date and the relatively low number of infants enrolled, in addition to a desire to oversimplify the underlying pathophysiology, have contributed to an inability to draw meaningful conclusions to direct clinical care. This article reviews the current literature on this topic in the preterm population and outlines the challenges that have been encountered in performing such trials.

Intervention and Outcome for Neonatal Hypotension.

Many observational studies have shown that infants with blood pressures (BPs) that are in the lower range for their gestational age tend to have increased complications such as an increased rate of significant intraventricular hemorrhage and adverse long-term outcome. This relationship does not prove causation nor should it create an indication for treatment. However, many continue to intervene with medication for low BP on the assumption that an increase in BP will result in improved outcome.

A wavelet-based algorithm for automated analysis of external tocography: How does it compare to human interpretation?

Background: Studies which use external tocography to explore the relationship between increased intrapartum uterine activity and foetal outcomes are feasible because the technology is safe and ubiquitous. However, periods of poor signal quality are common. We developed an algorithm which aims to calculate tocograph summary variables based on well-recorded contractions only, ignoring artefact and excluding sections deemed uninterpretable.

Fatality rates and use of systemic thrombolysis in pregnant women with pulmonary embolism.

Aims: Data on the early course and use of systemic thrombolysis in pregnant women with pulmonary embolism associated or not with haemodynamic failure are scarce. We investigated these aspects using the information from the German Nationwide Inpatient Registry (years 2005-2016).

Methods And Results: In Germany, all diagnoses referring to hospitalized patients are coded according to the International Classification of Diseases and Related Health Problems, 10th Revision with German Modification.

Defining "Haemodynamic Significance" of the Patent Ductus Arteriosus: Do We Have All the Answers?

Optimum management of the patent ductus arteriosus (PDA) in preterm infants remains one of the most debated topics within the field of neonatology. Despite numerous observational studies and over 60 randomized control trials, consensus on PDA management remains elusive. In order to make meaningful progress on the controversial issue of PDA management, several key factors must be thoroughly addressed; namely (1) accurate identification of infants at greatest risk of long-term morbidities from PDA exposure, (2) acceptance that the PDA is not a dichotomous entity and an individualised approach to its management is required for each neonate, (3) international consensus on what constitutes a haemodynamically significant PDA and (4) the incorporation of multi-organ assessment when evaluating the impact a PDA may pose on overall neonatal physiology.

The Impact of Technology on Prescribing Errors in Pediatric Intensive Care: A Before and After Study.

Background: Increased use of health information technology (HIT) has been advocated as a medication error reduction strategy. Evidence of its benefits in the pediatric setting remains limited. In 2012, electronic prescribing (ICCA, Philips, United Kingdom) and standard concentration infusions (SCIs)-facilitated by smart-pump technology-were introduced into the pediatric intensive care unit (PICU) of an Irish tertiary-care pediatric hospital.

Intraoperative cell salvage as part of a blood conservation strategy in an obstetric population with abnormal placentation at a large Irish tertiary referral centre: an observational study.

Background: Haemorrhagic morbidity is more common in women with abnormal placentation, that is placenta praevia or morbidly adherent placenta. The incidence of abnormal placentation is increasing due to rising caesarean section rates. Concerns regarding blood safety, blood shortages and soaring costs of blood processing have generated growing enthusiasm for blood conservation strategies.

Myocardial function in late preterm infants during the transitional period: comprehensive appraisal with deformation mechanics and non-invasive cardiac output monitoring.

Background: There is a paucity of functional data on mid-to-late preterm infants between 30+0 and 34+6 weeks gestation. We aimed to characterise transitional cardiopulmonary and haemodynamic changes during the first 48 hours in asymptomatic mid-to-late preterm infants.

Methods: Forty-five healthy preterm newborns (mean ± standard deviation) gestation of 32.

Preventing disease in the 21st century: early breast milk exposure and later cardiovascular health in premature infants.

Cardiovascular health of premature infants reaching early adulthood is an area of ongoing research. There is emerging evidence delineating the challenges faced by those individuals. Young adults born premature demonstrate a unique cardiac phenotype characterized by reduced biventricular volume, relatively lower systolic and diastolic function, and a disproportionate increase in muscle mass.

Impact of Introduction of a Clinical Pathway for the Management of Pyelonephritis on Obstetric Patients: a Quality Improvement Project.

Aim To determine whether the introduction of a clinical pathway for the treatment of pyelonephritis in obstetric patients would improve outcomes. Methods This was a retrospective study conducted in a maternity hospital using quantitative analysis methods. Patients who met laboratory and clinical criteria for pyelonephritis during data collection were included.

Alterations in fibrin formation and fibrinolysis in early onset-preeclampsia: Association with disease severity.

Objective: ; Early-onset preeclampsia is a rare pregnancy-specific disorder associated with significantly increased maternal and fetal morbidity and mortality. Whilst it is known that even normotensive pregnancies are associated with changes in clot formation and dissolution, the nature of how these changes differ in those with early onset preeclampsia has not been well established. We sought to evaluate parameters of fibrin formation and fibrinolysis in individuals with early onset preeclampsia in comparison to both pregnant and non-pregnant controls.

Circumferential and radial deformation assessment in premature infants: Ready for primetime?

Background: Speckle tracking echocardiography (STE) is a validated method to measure longitudinal deformation in premature infants, but there is a paucity of data on STE-derived circumferential and radial strain in this population. We assessed the feasibility and reproducibility of circumferential and radial deformation measurements in premature infants.

Methods: In a prospective study of 40 premature infants (<29 weeks of gestation at birth), STE-derived circumferential and radial strain, systolic strain rate (SRs), early diastolic strain rate (SRe), and late diastolic strain rate (SRa) were measured on day 2 and day 8.

Persistence of right ventricular dysfunction and altered morphometry in asymptomatic preterm Infants through one year of age: Cardiac phenotype of prematurity.

Introduction: Prematurity impacts myocardial development and may determine long-term outcomes. The objective of this study was to test the hypothesis that preterm neonates develop right ventricle dysfunction and adaptive remodelling by 32 weeks post-menstrual age that persists through 1 year corrected age.

Materials And Methods: A subset of 80 preterm infants (born <29 weeks) was selected retrospectively from a prospectively enrolled cohort and measures of right ventricle systolic function and morphology by two-dimensional echocardiography were assessed at 32 weeks post-menstrual age and at 1 year of corrected age.

Echocardiographic Assessment of Right Ventricular Afterload in Preterm Infants: Maturational Patterns of Pulmonary Artery Acceleration Time Over the First Year of Age and Implications for Pulmonary Hypertension.

Background: Assessment of pulmonary hemodynamics is critical in the diagnosis and management of cardiopulmonary disease of premature infants, but reliable noninvasive indices of pulmonary hemodynamics in preterm infants are lacking. Because pulmonary artery acceleration time (PAAT) is a validated noninvasive method to assess right ventricular (RV) afterload in infants and children, the aim of this study was to investigate the maturational changes of PAAT measures in preterm infants over the first year of age and to discern the impact of typical cardiopulmonary abnormalities on these measures.

Methods: In a prospective multicenter study of 239 preterm infants (<29 weeks at birth), PAAT was assessed at days 1, 2, and 5 to 7, at 32 and 36 weeks' postmenstrual age, and at 1-year corrected age.

Impaired Right Ventricular Performance Is Associated with Adverse Outcome after Hypoxic Ischemic Encephalopathy.

Asphyxiated neonates with hypoxic ischemic encephalopathy (HIE) are at risk of myocardial dysfunction; however, echocardiography studies are limited and little is known about the relationship between hemodynamics and brain injury. To analyze the association between severity of myocardial dysfunction and adverse outcome as defined by the composite of death and/or abnormal magnetic resonance imaging. Neonates with HIE undergoing therapeutic hypothermia were enrolled.
