Abnormal infant neurobehavior and later neurodevelopmental delays in children with critical CHD.

Infants with critical CHD have abnormal neurobehavior assessed by the Neonatal ICU Network Neurobehavioral Scales. This retrospective cohort study hypothesized associations between abnormal infant neurobehavior in the first month of life and later neurodevelopmental outcomes at 1-2 years of age. Associations between abnormal infant attention (orienting to and tracking stimuli) on the Neonatal ICU Network Neurobehavioral Scales and later motor, cognitive, and language neurodevelopmental outcomes on the Bayley Scales of Infant Development-III at follow-up were examined with descriptive statistics and univariable and multivariable regression. Multiple imputation was used to account for missing outcome data. 189 infants with critical CHD were included, and 69% had abnormal neurobehavioral attention scores. 58 (31%) returned as toddlers for neurodevelopmental follow-up, of which 23% had motor delay. Abnormal infant attention had high sensitivity (92%, 95% CI 60-100%) but low specificity (36%, 95% CI 23-52%) for later motor delay. Higher infant attention scores were associated with higher later motor scores in univariable analysis (coefficient 3.49, 95% CI 0.52,6.46, p = 0.025), but not in multivariable analyses. Neither cognitive nor language scores were associated with infant attention scores. Lower birth weight and male sex were significantly associated with lower motor scores in multivariable analysis (p = 0.048, 0.007). Although impaired infant attention is interdependent with other clinical and demographic risk factors, it may be a sensitive clinical marker of risk for later motor delay. In children with critical CHD, impaired infant attention may be capturing early signs of abnormal visual-motor neurodevelopment.

Ultrasonographic evaluation of endotracheal tube position in newborns with CHD.

Many studies have been conducted to determine the most reliable technique for evaluating the position of the endotracheal tube in patients receiving mechanical ventilation support. In this study, we aimed to determine the endotracheal tube position by ultrasonography in intubated patients with a diagnosis of critical CHD followed in the neonatal ICU. METHODS: In this prospective observational clinical study, we performed point-of-care ultrasound for endotracheal tube localisation in 65 intubated newborns with critical CHD. After routine radiography, each patient underwent point-of-care ultrasound examination with a portable ultrasonography device for endotracheal tube end-carina measurement. Endotracheal tube end-carina measurements on chest radiographs were compared with ultrasound images. RESULTS: The mean gestational age and birth weight were 37.8 ± 2.19 weeks and 2888 ± 595 g, respectively. Ultrasound images were obtained after an average of 2.08 ± 1.6 hours from the radiographs. The average ultrasound time allocated to each patient was 5 minutes. The mean endotracheal tube tip-to-carina distance on chest X-ray and ultrasound were optimally 1.33 ± 0.64 cm and 1.43 ± 0.67 cm, respectively. There was no significant difference between chest X-ray and ultrasound measurements in endotracheal tube end-carina distance values evaluated by the Bland-Altman method (mean difference 0.10 cm, p = 0.068). There was a linear correlation between the endotracheal tube tip-carina distance in ultrasound and radiography evaluation (r2 = 0.60, p < 0.001). CONCLUSION: It has been concluded that critical CHDs are frequently accompanied by vascular anomalies, and the endotracheal tube tip-carina distance measurement can be used by determining the carina section as a guide point in the ultrasonographic evaluation of the endotracheal tube location in this patient population.

The significance of an integrated management mode of prenatal diagnosis-postnatal treatment for critical congenital heart disease in newborns.

BACKGROUND: Congenital heart disease (CHD) is the most common congenital defect in human beings. The purpose of this article is to investigate impact of an integrated management mode of 'prenatal diagnosis-postnatal treatment' on birth, surgery, prognosis and complications associated with critical CHD (CCHD) in newborns. METHODS: A retrospective analysis of the medical records of newborns diagnosed with CCHD were divided into two groups: prenatal diagnosis and postnatal diagnosis. The demographics, clinical characteristics, surgical status, prognosis and complications of the two groups were compared and the differences identified. RESULTS: Among the 290 newborns with CCHD, 97 (33.4%) were prenatally diagnosed and 193 (66.6%) were postnatally diagnosed. Newborns in the prenatal diagnostic group were hospitalized immediately after birth, whereas the median age of admission was 6.00 (3.00-12.00) days in postnatal diagnostic group, P=0.000. In terms of postnatal symptoms and signs, the incidence of anhelation, cyanosis and cardiac murmur was higher in the postnatal diagnostic group. The rates of preoperative intubation, postoperative open chest exploration and treatment abandonment were higher in the postnatal diagnostic group. The postnatal diagnostic group was more prone to postoperative complications, such as pneumonia and hypoxic-ischemic brain damage. The preoperative mortality [0 (0.0%) vs. 12 (6.2%), P=0.028] in the prenatal diagnostic group was lower than that in the postnatal diagnostic group. And the one-year survival rate of the prenatal diagnostic group was higher (log-rank test P=0.034). CONCLUSIONS: The integrated management mode of prenatal diagnosis-postnatal treatment can improve postnatal symptoms, reduces complications, reduces preoperative mortality and increases one-year survival rates in newborns with CCHD.

Comparison of motor outcomes between preschool children with univentricular and biventricular critical heart disease not diagnosed with cerebral palsy or acquired brain injury.

This comparison study of two groups within an inception cohort aimed to compare the frequency of motor impairment between preschool children with univentricular and biventricular critical congenital heart disease (CHD) not diagnosed with cerebral palsy/acquired brain injury, describe and compare their motor profiles and explore predictors of motor impairment in each group.Children with an intellectual quotient <70 or cerebral palsy/acquired brain injury were excluded. Motor skills were assessed with the Movement Assessment Battery for Children-2. Total scores <5th percentile indicated motor impairment. Statistical analysis included χ2 test and multiple logistic regression analysis.At a mean age of 55.4 (standard deviation 3.77) months, motor impairment was present in 11.8% of those with biventricular critical CHD, and 32.4% (p < 0.001) of those with univentricular critical CHD. The greatest difference between children with biventricular and univentricular CHD was seen in total test scores 8.73(2.9) versus 6.44(2.8) (p < 0.01) and in balance skills, 8.84 (2.8) versus 6.97 (2.5) (p = 0.001). Manual dexterity mean scores of children with univentricular CHD were significantly below the general population mean (>than one standard deviation). Independent odds ratio for motor impairment in children with biventricular critical CHD was presence of chromosomal abnormality, odds ratio 10.9 (CI 2.13-55.8) (p = 0.004); and in children with univentricular critical CHD odds ratio were: postoperative day 1-5 highest lactate (mmol/L), OR: 1.65 (C1.04-2.62) (p = 0.034), and dialysis requirement any time before the 4.5-year-old assessment, OR: 7.8 (CI 1.08-56.5) (p = 0.042).Early assessment of motor skills, particularly balance and manual dexterity, allows for intervention and supports that can address challenges during the school years.

Effect of newborn screening for critical CHD on healthcare utilisation.

OBJECTIVE: To evaluate the impact of state-mandated policies for pulse oximetry screening on healthcare utilisation, with a focus on use of echocardiograms. DATA SOURCES/STUDY SETTING: Healthcare Cost and Utilisation Project, Statewide Inpatient Databases from 2008 to 2014 from six states. METHODS: We defined pre- and post-mandate cohorts based on dates when pulse oximetry became mandated in each state. Linear segmented regression models for interrupted time series assessed associations between implementation of the screening and changes in rate of newborns with Critical CHD-negative echocardiogram results. We also evaluated the changes in rate of newborns who underwent echocardiogram but were not diagnosed with any health issues that could cause hypoxemia. RESULTS: We identified 5967 critical CHD-negative echocardiograms (2847 and 3120 in the pre- and post-mandate periods, respectively). Our models detected a statistically significant increasing trend in rate of critical CHD-negative echocardiograms in the pre-mandate period (Incidence Rate Ratio: 1.08, p = 0.02), but did not detect any statistical differences in changes between pre- and post-mandate periods (Incidence Rate Ratio: 0.93, p = 0.14). Among non-Whites, an increasing trend of Critical CHD-negative echocardiogram during the pre-mandate period was detected (Incidence Rate Ratio 1.12, p < 0.01) and was attenuated during the post-mandate period (Incidence Rate Ratio 0.89, p = 0.02). Similar results were observed in the sensitivity analyses among both Whites and non-Whites. CONCLUSIONS: Results suggest that mandatory state screening policies are associated with reductions in false-positive screening rates for hypoxemic conditions, with reductions primarily attributed to trends among non-Whites.

Diagnosis and Management of Critical Congenital Heart Diseases in the Newborn.

Congenital heart disease (CHD) has been one of the most important contributors to neonatal mortality in the western world for the past 2 decades. With improvement in basic neonatal medical care in most parts of our country, the traditional contributors to neonatal mortality such as birth asphyxia and infections have reduced in numbers. This has hence thrust greater focus on CHD. Facilities with capability to diagnose and intervene on neonates with critical CHD are available in most states. Refinements in surgical techniques and advances in post-operative care have ensured that most neonates with critical CHD can undergo surgical or interventional procedures with very low mortality and can be expected to survive to adulthood with a reasonable quality of life. Unrecognized critical CHD could however result in death in the neonatal period. Focus has hence shifted towards sensitizing pediatricians about timely recognition of neonates with CHD. In this article, authors discuss the presentation and initial stabilization of neonates with CHD and attempt to provide practical solutions which can aid early diagnosis of CHD in the Indian scenario.

Infants born with critical CHD in Arizona and capacities of birth centres for screening and management.

OBJECTIVES: The aims of this study were to identify locations of births in Arizona with critical CHD, as well as to assess the current use of pulse-oximetry screening and capacities of birth centres to manage a positive screen. Study design Infants (n=487) with a potentially critical CHD were identified from the Arizona Department of Health Services from 2012 and 2013; charts were retrospectively reviewed. Diagnosis was confirmed using echocardiographies. ArcGIS was used to generate maps to visualise the location of treating facility and mother's residence. Birth centres were surveyed to assess screening practices and capacities to manage critical CHD in 2015. RESULTS: Of the 272 patients identified with critical CHD, 52% had been diagnosed prenatally. Patients travelled an average distance of 55.1 miles to their treating facility. Mortality was not related to prenatal diagnosis (p=0.30), living at a high elevation (p=0.82), or to distance travelled to the treating facility (p=0.68). Of 50 birth centres, 33 responded to the survey and all centres practiced critical CHD screening. A total of 25 centres could perform paediatric echocardiographies; 64% of these centres could digitally transmit echocardiograms. In all, 24 birth centres maintained access to prostaglandins. CONCLUSIONS: Pulse-oximetry screening in newborns is currently implemented in the majority of Arizona hospitals. Although most centres could perform initial management steps following a positive screen, access to paediatric cardiology services was limited. Patients with critical CHD sometimes travelled a great distance to treating facilities. Digital transmission of echocardiograms or tele-echocardiography would reduce the distance travelled for the management of a positive screen, decrease the financial burden of transportation, and expedite care for critically ill neonates.
