ABSTRACT
Cardiac point-of-care ultrasound (POCUS) is a technology increasingly leveraged at the bedside by pediatric critical care and neonatology providers to identify real-time hemodynamic pathophysiology. We present a framework for (1) identifying the scope of cardiac POCUS within the clinical practice setting, (2) standardizing views for protocolized hemodynamic assessment relevant to pediatric critical illness and (3) integrating POCUS findings for therapeutic guidance. Within the review, we also discuss practical strengths and limitations to image acquisition and interpretation within the varied cardiac POCUS views. Finally, we explore unique considerations within the neonatal population. Conclusion: Cardiac POCUS is a technology and tool that reveals important real-time information at the bedside of the critically ill child and infant. Understanding strengths and limitations of cardiac POCUS views and protocolizing an approach to answer focused clinical questions provides a framework for training and translation to clinical care. What is Known: ⢠Ultrasound technology is now ubiquitous among pediatric critical care and neonatology settings, and growing literature supports an expanded role in not only procedural but also diagnostic applications. ⢠Cardiac POCUS influences provider perception of pathophysiology and changes clinical management. What is New: ⢠Effective cardiac POCUS training and subsequent translation to clinical practice should improve when clinical questions and protocolized approaches to image acquisition are standardized within a specialty. ⢠Cardiac POCUS views have strengths and limitations which must be recognized when assessing the hemodynamic profile of a child or neonate.

Outline a quality initiative establishing an institutional service line for neonatal transcatheter device closure of the patent ductus arteriosus (TDC-PDA). A retrospective descriptive observational study surrounds programmatic approach to TDC-PDA in premature neonates with process measure spanning education, implementation, referral, and post-procedural care. Metrics tracked pre- and post-program creation with statistical analyses performed. Neonatal TDC-PDA referrals increased exponentially since program inception (n = 13 in year prior; n = 42 year 1; n = 74 year 2), especially in patients weighing less than 1.3 kg (12.5%; 55%; 50%), and were associated with an increased procedural success rate (81%; 95%; 99%). Procedural checklist creation decreased procedural "out of isolette" time (median 93 min; 59; 52), and procedural-related complication or clinical sequelae (19%; 12%; 4%). A multidisciplinary service line and program dedicated to neonatal TDC-PDA can result in a significant increase in referrals as well as procedural efficacy and safety for this medically fragile population.
ABSTRACT
OBJECTIVE: To investigate the association of congenital heart disease (CHD) with morbidity and mortality of very low birth weight (VLBW) infants. STUDY DESIGN: This matched case-control study included VLBW infants born at a single institution between 2001 and 2015. The primary outcome was mortality. Secondary outcomes included necrotizing enterocolitis, bronchopulmonary dysplasia (BPD), sepsis, retinopathy of prematurity, and intraventricular hemorrhage. These outcomes were assessed by comparing VLBW-CHDs with control VLBW infants matched by gestational age within a week, birth weight within 500 g, sex, and birth date within a year using conditional logistic regression. Multivariable logistic regression analyzed differences in outcomes in the VLBW-CHD group between two birth periods (2001-2008 and 2009-2015) to account for changes in practice. RESULTS: In a cohort of 44 CHD infants matched with 88 controls, the mortality rate was 27% in infants with CHD and 1% in controls (p < 0.0001). The VLBW-CHDs had increased BPD; (odds ratio [OR]: 7.70, 95% confidence interval [CI]: 1.96-30.29) and sepsis (OR: 10.59, 95% CI: 2.99-37.57) compared with the control VLBWs. When adjusted for preoperative ventilator use, the VLBW-CHDs still had significantly higher odds of BPD (OR: 6.97, 95% CI: 1.73-28.04). VLBW-CHDs also had significantly higher odds of both presumed and culture-positive sepsis as well as late-onset sepsis than their matched controls. There were no significant differences in outcomes between the two birth periods. CONCLUSION: VLBW-CHDs showed higher odds of BPD, sepsis, and mortality than VLBW infants without CHD. Future research should focus on the increased mortality and specific complications encountered by VLBW infants with CHD and implement targeted strategies to address these risks. KEY POINTS: · Incidence of CHD is higher in preterm infants than in term infants but the incidence of their morbidities is not well described.. · VLBW infants with CHD have higher odds of mortality, bronchopulmonary dysplasia, and sepsis.. · Future research is needed to implement targeted preventive responses..
ABSTRACT
Point-of-care ultrasound (POCUS) has increasingly been used by neonatal providers in neonatal intensive care units in the United States. However, there is a lack of literature addressing the complexities of POCUS coding and billing practices in the United States. This article describes the coding terminology and billing process especially those relevant to neonatal POCUS. We elucidate considerations for neonatal POCUS billing framework and workflow integration. Directions on image storage and supporting documentation to facilitate efficient reimbursement, compliance with billing regulations, and appeal to insurance claim denial are discussed. KEY POINTS: · Code neonatal POCUS procedure precisely allows accurate reimbursement and reduced errors in billing.. · Document details to support medical necessity and reimbursement claims effectively.. · Adhere to regulations to avoid audits, denials, and ensure proper reimbursement..
ABSTRACT
BACKGROUND: Inhaled nitric oxide (iNO) is widely used for the management of infants with congenital diaphragmatic hernia (CDH); however, evidence of benefit is limited. METHODS: This is a multicenter cohort study using data from the Congenital Diaphragmatic Hernia Study Group between 2015 and 2020. The impact of early iNO use in the first 3 days of life prior to ECLS use on mortality or ECLS use was explored using multivariate logistic regression models and subgroup analyses. RESULTS: Of the 1777 infants, 863 (48.6%) infants received early iNO treatment. Infants receiving iNO had lower birth weight, larger defect size, more severe pulmonary hypertension, and abnormal ventricular size and function. After controlling for these factors, early iNO use was associated with increased mortality (aOR 2.06, 95% CI 1.05-4.03, P = 0.03) and increased ECLS use (aOR 3.44, 95% CI 2.11-5.60, P < 0.001). Subgroup analyses after stratification by echocardiographic characteristics and defect size revealed no subgroup with a reduction in mortality or ECLS use. CONCLUSIONS: Use of iNO in the first 3 days of life prior to ECLS was not associated with a reduction in mortality or ECLS use in either the regression models or the subgroup analyses. The widespread use of iNO in this vulnerable population requires reconsideration. IMPACT: Evidence to support widespread use of iNO for infants with congenital diaphragmatic hernia is limited. The use of iNO in the first 3 days of life was associated with significantly increased mortality and ECLS use. Stratification by echocardiographic characteristics and defect size did not reveal a subgroup that benefited from iNO. Even the subset of patients with R-to-L shunts at both ductal and atrial levels, a surrogate for elevated pulmonary arterial pressures in the absence of significantly decreased LV compliance, did not benefit from early iNO use. Early iNO therapy was of no benefit in the management of acute pulmonary hypertension in infants with congenital diaphragmatic hernia, supporting reconsideration of its use in this population.

To assess success of peripheral arterial line (PAL) placement after implementing a point-of-care ultrasound (POCUS) program in a neonatal intensive care unit. This was a retrospective chart review of infants who underwent successful PAL placement from January 2019 to March 2021. Outcomes included first-attempt success and the number of attempts with and without the use of POCUS. Among 80 PALs, 36% were POCUS-guided. All POCUS-guided lines were placed by providers with < 5 years neonatology experience. Among infants ≥ 2.5 kg, the use of POCUS was associated with fewer attempts compared to non-POCUS PAL placement (1 vs. 2, p = 0.035). Conclusions: Use of POCUS for PAL placement was associated with fewer attempts for successful placement in infants ≥ 2.5 kg by providers with less neonatology experience compared with traditional method. What is Known: ⢠Arterial line placement in neonates has been traditionally done by palpation and can be technically challenging. ⢠POCUS is an emerging tool in the NICU with increasing number of less clinically experienced providers in the NICU having access to ultrasound. What is New: ⢠Use of POCUS by less experienced clinicians for arterial line placement resulted in fewer attempts compared to the traditional landmark-based approach in a cohort of neonates.

Sudden unexpected clinical deterioration or cardiorespiratory instability is common in neonates and is often referred as a "crashing" neonate. The established resuscitation guidelines provide an excellent framework to stabilize and evaluate these infants, but it is primarily based upon clinical assessment only. However, clinical assessment in sick neonates is limited in identifying underlying pathophysiology. The Crashing Neonate Protocol (CNP), utilizing point-of-care ultrasound (POCUS), is specifically designed for use in neonatal emergencies. It can be applied both in term and pre-term neonates in the neonatal intensive care unit (NICU). The proposed protocol involves a stepwise systematic assessment with basic ultrasound views which can be easily learnt and reproduced with focused structured training on the use of portable ultrasonography (similar to the FAST and BLUE protocols in adult clinical practice). We conducted a literature review of the evidence-based use of POCUS in neonatal practice. We then applied stepwise voting process with a modified DELPHI strategy (electronic voting) utilizing an international expert group to prioritize recommendations. We also conducted an international survey among a group of neonatologists practicing POCUS. The lead expert authors identified a specific list of recommendations to be included in the proposed CNP. This protocol involves pre-defined steps focused on identifying the underlying etiology of clinical instability and assessing the response to intervention.Conclusion: To conclude, the newly proposed POCUS-based CNP should be used as an adjunct to the current recommendations for neonatal resuscitation and not replace them, especially in infants unresponsive to standard resuscitation steps, or where the underlying cause of deterioration remains unclear. What is known? ⢠Point-of-care ultrasound (POCUS) is helpful in evaluation of the underlying pathophysiologic mechanisms in sick infants. What is new? ⢠The Crashing Neonate Protocol (CNP) is proposed as an adjunct to the current recommendations for neonatal resuscitation, with pre-defined steps focused on gaining information regarding the underlying pathophysiology in unexplained "crashing" neonates. ⢠The proposed CNP can help in targeting specific and early therapy based upon the underlying pathophysiology, and it allows assessment of the response to intervention(s) in a timely fashion.

OBJECTIVE: Decreased near-infrared spectroscopy (NIRS) measures of renal oxygen saturation (Rsat) have identified preterm infants with a hemodynamically significant patent ductus arteriosus (hsPDA). NIRS may further identify infants at risk for acute kidney injury (AKI) in a population with concern for hsPDA. STUDY DESIGN: Review of infants ≤29 weeks' gestation undergoing NIRS and echocardiography due to concern for hsPDA. The hsPDA was defined by two of the following: moderate-large size, left to right shunt, aortic flow reversal, left atrial enlargement. AKI was defined by neonatal modified Kidney Disease Improving Global Outcomes (KDIGO). Rsat and cerebral saturation (Csat), averaged over 1 hour, were evaluated for the 24-hour period around echocardiography. RESULTS: Among 77 infants, 29 (38%) had AKI by neonatal modified KDIGO criteria. hsPDA was found on echocardiography in 59 (77%). There were no differences in hsPDA in infants with and without AKI (p = 0.1). Rsat was not associated with AKI (p = 0.3). Infants on dopamine had less Rsat variability (p < 0.01). CONCLUSION: Rsat prior to echocardiography did not discriminate AKI in this cohort of preterm infants at risk for hsPDA; however, data may not capture optimal timing of Rsat measurement before AKI. KEY POINTS: · No Rsat value was found to be associated with the development of AKI.. · The optimal timing of Rsat measurement should be evaluated in infants at risk for hsPDA.. · NIRS bedside monitoring of Csat and Rsat measures may be useful in trending perfusion patterns.. · Identification of those at high risk for AKI may allow for more careful kidney function monitoring..
ABSTRACT
OBJECTIVE: Describe the association between cardiac dysfunction and death or moderate-to-severe abnormalities on brain magnetic resonance imaging (MRI) in neonates undergoing therapeutic hypothermia for hypoxic ischemic encephalopathy (HIE). STUDY DESIGN: Retrospective study in neonates with moderate or severe HIE undergoing therapeutic hypothermia between 2008 and 2017. Primary outcome was death or moderate-to-severe brain injury using the Barkovich score. Conventional and speckle-tracking echocardiography measures were extracted from available echocardiograms to quantify right (RV) and left (LV) ventricular functions. RESULTS: A total of 166 newborns underwent therapeutic hypothermia of which 53 (36.5%) had echocardiography performed. Ten (19%) died prior to hospital discharge, and 11 (26%) had moderate-to-severe brain injury. There was no difference in chronologic age at echocardiography between the normal and adverse outcome groups (22 [±19] vs. 28 [±21] hours, p = 0.35). Cardiac findings in newborns with abnormal outcome included lower systolic and diastolic blood pressure (BP) at echocardiography (p = 0.004) and decreased tricuspid annular plane systolic excursion (a marker of RV systolic function; p = 0.01), while the ratio of systolic pulmonary artery (PA) pressure to systolic BP indicated isosystemic pressures (>2/3 systemic) in both groups. A multilogistic regression analysis, adjusting for weight and seizure status, indicated an association between abnormal outcome and LV function by longitudinal strain, as well as by ejection fraction. CONCLUSION: Newborns who died or had moderate-to-severe brain injury had a higher incidence of cardiac dysfunction but similar PA pressures when compared with those who survived with mild or no MRI abnormalities. KEY POINTS: · Newborns with HIE with functional LV/RV dysfunction are at risk for death or brain injury.. · All neonates with HIE had elevated pulmonary pressure, but neonates with poor outcome had RV dysfunction.. · When evaluating newborns with HIE by echocardiography, beyond estimation of pulmonary pressure, it is important to assess biventricular function..

BACKGROUND: In newborns with hypoxic-ischaemic encephalopathy, more profound altered right and left ventricular function has been associated with mortality or brain injury. Mechanisms underlying cardiac dysfunction in this population are thought to be related to the persistence of increased pulmonary vascular resistance and myocardial ischaemia. We sought to compare cardiac function in newborns with hypoxic-ischaemic encephalopathy to controls using echocardiography. METHODS: We did a retrospective case-control study with moderate or severe hypoxic-ischaemic encephalopathy between 2008 and 2017. Conventional and speckle-tracking echocardiography measures were extracted to quantify right and left ventricular systolic and diastolic function. Fifty-five newborns with hypoxic-ischaemic encephalopathy were compared to 28 controls. RESULTS: Hypoxic-ischaemic encephalopathy newborns had higher estimated systolic pulmonary pressure (62.5 ± 15.0 versus 43.8 ± 17.3 mmHg, p < 0.0001) and higher systolic pulmonary artery pressure/systolic blood pressure ratio [101 ± 16 (iso-systemic) versus 71 ± 27 (2/3 systemic range) %, p < 0.0001]. Tricuspid annular plane systolic excursion was decreased (7.5 ± 2.2 versus 9.0 ± 1.4 mm, p = 0.002), E/e' increased (7.9 ± 3.3 versus 5.8 ± 2.0, p = 0.01), and right ventricle-myocardial performance index increased (68.1 ± 21.5 versus 47.8 ± 9.5, p = 0.0001) in hypoxic-ischaemic encephalopathy. Conventional markers of left ventricle systolic function were similar, but e' velocity (0.059 ± 0.019 versus 0.070 ± 0.01, p = 0.03) and left ventricle-myocardial performance index were statistically different (77.9 ± 26.2 versus 57.9 ± 11.2, p = 0.001). The hypoxic-ischaemic encephalopathy group had significantly altered right and left ventricular deformation parameters by speckle-tracking echocardiography. Those with decreased right ventricle-peak longitudinal strain were more likely to have depressed left ventricle-peak longitudinal strain. CONCLUSION: Newborns with hypoxic-ischaemic encephalopathy have signs of increased pulmonary pressures and altered biventricular systolic and diastolic function.

Point-of-care ultrasound (POCUS) refers to the use of portable ultrasound (US) applications at the bedside, performed directly by the treating physician, for either diagnostic or procedure guidance purposes. It is being rapidly adopted by traditionally non-imaging medical specialties across the globe. Recent international evidence-based guidelines on POCUS for critically ill neonates and children were issued by the POCUS Working Group of the European Society of Pediatric and Neonatal Intensive Care (ESPNIC). Currently there are no standardized national or international guidelines for its implementation into clinical practice or even the training curriculum to monitor quality assurance. Further, there are no definitions or methods of POCUS competency measurement across its varied clinical applications. CONCLUSION: The Hippocratic Oath suggests medical providers do no harm to their patients. In our continued quest to uphold this value, providers seeking solutions to clinical problems must often weigh the benefit of an intervention with the risk of harm to the patient. Technologies to guide diagnosis and medical management present unique considerations when assessing possible risk to the patient. Frequently risk extends beyond the patient and impacts providers and the institutions in which they practice. POCUS is an emerging technology increasingly incorporated in the care of children across varied clinical specialties. Concerns have been raised by clinical colleagues and regulatory agencies regarding appropriate POCUS use and oversight. We present a framework for assessing the risk of POCUS use in pediatrics and suggest methods of mitigating risk to optimize safety and outcomes for patients, providers, and institutions. WHAT IS KNOWN: ⢠The use POCUS by traditionally non-imaging pediatric specialty physicians for both diagnostic and procedural guidance is rapidly increasing. ⢠Although there are international guidelines for its indications, currently there is no standardized guidance on its implementation in clinical practice. WHAT IS NEW: ⢠Although standards for pediatric specialty-specific POCUS curriculum and training to competency have not been defined, POCUS is likely to be most successfully incorporated in clinical care when programmatic infrastructural elements are present. ⢠Risk assessment is a forward-thinking process and requires an imprecise calculus that integrates considerations of the technology, the provider, and the context in which medical care is delivered. Medicolegal considerations vary across countries and frequently change, requiring providers and institutions to understand local regulatory requirements and legal frameworks to mitigate the potential risks of POCUS.

OBJECTIVES: Umbilical venous cannulation is the favored approach to perinatal central access worldwide but has a failure rate of 25-50% and the insertion technique has not evolved in decades. Improving the success of this procedure would have broad implications, particularly where peripherally inserted central catheters are not easily obtained and in neonates with congenital heart disease, in whom umbilical access facilitates administration of inotropes and blood products while sparing vessels essential for later cardiac interventions. We sought to use real-time, point-of-care ultrasound to achieve central umbilical venous access in patients for whom conventional, blind placement techniques had failed. DESIGN: Multicenter case series, March 2019-May 2021. SETTING: Cardiac and neonatal ICUs at three tertiary care children's hospitals. PATIENTS: We identified 32 neonates with congenital heart disease, who had failed umbilical venous cannulation using traditional, blind techniques. INTERVENTIONS: Real-time ultrasound guidance and liver pressure were used to replace malpositioned catheters and achieve successful placement at the inferior cavoatrial junction. MEASUREMENTS AND MAIN RESULTS: In 32 patients with failed prior umbilical venous catheter placement, real-time ultrasound guidance was used to successfully "rescue" the line and achieve central position in 23 (72%). Twenty of 25 attempts (80%) performed in the first 48 hours of life were successful, and three of seven attempts (43%) performed later. Twenty-four patients (75%) were on prostaglandin infusion at the time of the procedure. We did not identify an association between patient weight or gestational age and successful placement. CONCLUSIONS: Ultrasound guidance has become standard of care for percutaneous central venous access but is a new and emerging technique for umbilical vessel catheterization. In this early experience, we report that point-of-care ultrasound, together with liver pressure, can be used to markedly improve success of placement. This represents a significant advance in this core neonatal procedure.

OBJECTIVE: The objective of this article was to correlate hypotension and cerebral saturation from near-infrared spectroscopy (cNIRS) in neonates on dopamine. STUDY DESIGN: Retrospective review of neonates receiving dopamine between August 2018 and 2019 was performed. Hypotension thresholds included mean arterial pressure (MAP) of postmenstrual age (PMA) ± 5 and 30 mm Hg and gestational age (GA) ± 5 mm Hg. Time below threshold MAP was compared with time with cerebral hypoxia (cNIRS <55%). RESULTS: Hypotension occurred 6 to 33% of the time on dopamine in 59 cases. Hypotension did not correlate with abnormal cNIRS overall, within PMA subgroups or by outcomes. Hypotensive periods with MAP < GA had fewer corresponding percent time with abnormal cNIRS events (3.7 ± 1.3%) compared with MAP < PMA (11.9 ± 4.9%, p < 0.003) or 30 mm Hg thresholds (12.2 ± 4.7%, p < 0.0001). In most premature infants, mean cNIRS values during hypotension were still within normal range (57 ± 6%). CONCLUSION: cNIRS may be a more clinically relevant measure than MAP for the assessment of neonatal hypotension. KEY POINTS: · Hypotension occurred 6 to 33% of the time on dopamine in 59 cases.. · Hypotension did not correlate with abnormal cNIRS overall, within PMA subgroups or by outcomes.. · MAP. · We found no cNIRS difference between IVH grades, mortality, average Hct, lactates, or urine output.. · cNIRS may be a more clinically relevant measure than MAP for the assessment of neonatal hypotension..
ABSTRACT
OBJECTIVE: In the adult and pediatric critical care population, point-of-care ultrasound (POCUS) can aid in diagnosis, patient management, and procedural accuracy. For neonatal providers, training in ultrasound and the use of ultrasound for diagnosis and management is increasing, but use in the neonatal intensive care unit (NICU) is still uncommon compared with other critical care fields. Our objective was to describe the process of implementing a POCUS program in a large academic NICU and evaluate the role of ultrasound in neonatal care during early adaption of this program. STUDY DESIGN: A POCUS program established in December 2018 included regular bedside scanning, educational sessions, and quality assurance, in collaboration with members of the cardiology, radiology, and pediatric critical care divisions. Core applications were determined, and protocols outlined guidelines for image acquisition. An online database included images and descriptive logs for each ultrasound. RESULTS: A total of 508 bedside ultrasounds (76.8% diagnostic and 23.2% procedural) were performed by 23 providers from December 2018 to December 2020 in five core diagnostic applications: umbilical line visualization, cardiac, lung, abdomen (including bladder), and cranial as well as procedural applications. POCUS guided therapy and influenced clinical management in all applications: umbilical line assessment (26%), cardiac (33%), lung (14%), abdomen (53%), and cranial (43%). With regard to procedural ultrasound, 74% of ultrasound-guided arterial access and 89% of ultrasound-guided lumbar punctures were successful. CONCLUSIONS: Implementation of a POCUS program is feasible in a large academic NICU and can benefit from a team approach. Establishing a program in any NICU requires didactic opportunities, a defined scope of practice, and imaging review with quality assurance. Bedside clinician performed ultrasound findings can provide valuable information in the NICU and impact clinical management. KEY POINTS: · Use of point-of-care ultrasound is increasing in neonatology and has been shown to improve patient care.. · Implementation of a point-of-care ultrasound program requires the definition of scope of practice and can benefit from the support of other critical care and imaging departments and providers.. · Opportunities for point-of-care ultrasound didactics, imaging review, and quality assurance can enhance the utilization of bedside ultrasound..
ABSTRACT
OBJECTIVE: Bronchopulmonary dysplasia (BPD) remains the most common late morbidity for extremely premature infants. Care of infants with BPD requires a longitudinal approach from the neonatal intensive care unit to ambulatory care though interdisciplinary programs. Current approaches for the development of optimal programs vary among centers. STUDY DESIGN: We conducted a survey of 18 academic centers that are members of the BPD Collaborative, a consortium of institutions with an established interdisciplinary BPD program. We aimed to characterize the approach, composition, and current practices of the interdisciplinary teams in inpatient and outpatient domains. RESULTS: Variations exist among centers, including composition of the interdisciplinary team, whether the team is the primary or consult service, timing of the first team assessment of the patient, frequency and nature of rounds during the hospitalization, and the timing of ambulatory visits postdischarge. CONCLUSION: Further studies to assess long-term outcomes are needed to optimize interdisciplinary care of infants with severe BPD. KEY POINTS: · Care of infants with BPD requires a longitudinal approach from the NICU to ambulatory care.. · Benefits of interdisciplinary care for children have been observed in other chronic conditions.. · Current approaches for the development of optimal interdisciplinary BPD programs vary among centers..
ABSTRACT
OBJECTIVE: To test the hypothesis that a fetal stratification pathway will effectively discriminate between infants at different levels of risk for surgical coarctation and reduce unnecessary medicalization. STUDY DESIGN: We performed a pre-post nonrandomized study in which we prospectively assigned fetuses with prenatal concern for coarctation to 1 of 3 risk categories and implemented a clinical pathway for postnatal management. Postnatal clinical outcomes were compared with those in a historical control group that were not triaged based on the pathway. RESULTS: The study cohort comprised 109 fetuses, including 57 treated along the fetal coarctation pathway and 52 historical controls. Among mild-risk fetuses, 3% underwent surgical coarctation repair (0% of those without additional heart defects), compared with 27% of moderate-risk and 63% of high-risk fetuses. The combined fetal aortic, mitral, and isthmus z-score best discriminated which infants underwent surgery (area under the curve = 0.78; 95% CI, 0.66-0.91). Compared with historical controls, infants triaged according to the fetal coarctation pathway had fewer delivery location changes (76% vs 55%; P = .025) and less umbilical venous catheter placement (74% vs 51%; P = .046). Trends toward shorter intensive care unit stay, hospital stay, and time to enteral feeding did not reach statistical significance. CONCLUSIONS: A stratified risk-assignment pathway effectively identifies a group of fetuses with a low rate of surgical coarctation and reduces unnecessary medicalization in infants who do not undergo aortic surgery. Incorporation of novel measurements or imaging techniques may improve the specificity of high-risk criteria.

Cardiac point of care ultrasound (POCUS) is increasingly being utilized in neonatal intensive care units to provide information in real time to aid clinical decision making. While training programs and scope of practice have been well defined for other specialties, such as adult critical care and emergency medicine, there is a lack of structure for neonatal cardiac POCUS. A more comprehensive and advanced hemodynamic evaluation by a neonatologist has previously published its own clinical guidelines and specific rigorous training programs have been established to achieve competency in neonatal hemodynamics. However, it is becoming increasingly evident that access and training for basic cardiac assessment by ultrasound enhances bedside clinical care for specific indications. Recently, expert consensus POCUS guidelines for use in neonatal and pediatric intensive care endorsed by the European Society of Pediatric and Neonatal Intensive Care (ESPNIC) have been published to guide the clinicians in using POCUS for specific indications, though the line between cardiac POCUS and advanced hemodynamic evaluation remains somewhat fluid.Conclusion: This article is focused on neonatal cardiac POCUS and its evolution, value, and limitations in the modern neonatal clinical practice. Cardiac POCUS can provide physiological and hemodynamic information in making clinical decisions while dealing with neonatal emergencies. However, it should be applied only for the specific indications and should be performed by a clinician trained in cardiac POCUS. There is an urgent need of developing cardiac POCUS curriculum and certification to support a widespread and safe use in neonates. What is Known: ⢠International training guidelines and curriculum have been published for neonatologist-performed echocardiography (NPE) or targeted neonatal echocardiography (TNE). ⢠International evidence-based guidelines for use of point of care ultrasound (POCUS) in neonates and children have been recently published. What is New: ⢠Cardiac POCUS is increasingly being incorporated in neonatal practice for emergency situations. However, one must be aware of its specific indications and limitations, especially for the neonatal clinical practice. ⢠Cardiac POCUS and NPE/TNE are continuum of cardiac imaging with different indications and training requirements.

BACKGROUND: Near-infrared spectroscopy (NIRS) measures of cerebral saturation (Csat) and renal saturation (Rsat) in extreme premature newborns may be affected by systemic blood flow fluctuations. Despite increasing clinical use of NIRS to monitor tissue saturation in the premature infant, validation of NIRS measures as a correlate of blood flow is still needed. We compared echocardiography (ECHO) derived markers of ascending aorta (AscAo) and descending aorta (DesAo) blood flow with NIRS measurements obtained during the ECHO. METHODS: Newborns < 29 weeks' gestation (2013-2017) underwent routine NIRS monitoring. Csat, Rsat and systemic saturation at the time of ECHO were retrospectively analyzed and compared with Doppler markers of aortic flow. Renal and cerebral fractional tissue oxygen extraction (rFTOE and cFTOE, respectively) were calculated. Mixed effects models evaluated the association between NIRS and Doppler markers. RESULTS: Forty-nine neonates with 75 Csat-ECHO and 62 Rsat-ECHO observations were studied. Mean post-menstrual age was 28.3 ± 3.8 weeks during the ECHO. Preductal measures including AscAo velocity time integral (VTI) and AscAo output were correlated with Csat or cFTOE, while postductal measures including DesAo VTI, DesAo peak systolic velocity, and estimated DesAo output were more closely correlated with Rsat or rFTOE. CONCLUSIONS: NIRS measures are associated with aortic blood flow measurements by ECHO in the extremely premature population. NIRS is a tool to consider when following end organ perfusion in the preterm infant.

While outcomes for neonates with congenital heart disease have improved, it is apparent that substantial variability exists among centers with regard to the multidisciplinary approach to care for this medically fragile patient population. We endeavored to understand the landscape of neonatal cardiac care in the United States. A survey was distributed to physicians who provide neonatal cardiac care in the United States regarding (1) collaborative efforts in care of neonates with congenital heart disease (CHD); (2) access to neonatal cardiac training; and (3) barriers to the implementation of protocols for neonatal cardiac care. Responses were collected from 10/2018 to 6/2019. We received responses from 172 of 608 physicians (28% response rate) from 89 centers. When compared to responses received from physicians at low-volume centers (< 300 annual bypass cases), those at high-volume centers reported more involvement from the neurodevelopmental teams (58% vs. 29%; P = 0.012) and a standardized transition to outpatient care (68% vs. 52%; P = 0.038). While a majority of cardiothoracic surgery and anesthesiology respondents reported multidisciplinary involvement, less than half of cardiology and neonatology supported this statement. The most commonly reported obstacles to multidisciplinary engagement were culture (61.6%) and logistics (47.1%). Having a standardized neonatal cardiac curriculum for neonatal fellows was positively associated with the perception that multidisciplinary collaboration was "always" in place (53% vs. 40%; P = 0.09). There is considerable variation among centers in regard to personnel involved in neonatal cardiac care, related education, and perceived multidisciplinary collaboration among team members. The survey findings suggest the need to establish concrete standards for neonatal cardiac surgical programs, with ongoing quality improvement processes.

OBJECTIVE: Pulmonary hypertension (PH) has been described in the neonatal omphalocele population. This study was aimed to describe cardiac function and PH severity using echocardiography in newborns with giant omphalocele (GO) and with non-GO and determine if right ventricular (RV) dysfunction is associated with mortality. STUDY DESIGN: Retrospective, single-center analysis of first echocardiography among neonatal omphalocele patients born between 2004 and 2017 was conducted. Multivariate logistic and univariate Cox's regression was constructed to measure hazard ratio (HR) for death outcome. RESULTS: There were 32 newborns, of whom 18 were GO and 7 died. GO had increased systolic pulmonary arterial to systolic systemic blood pressure ratio (97% [isosystemic] vs. 73% [three-fourths systemic] p = 0.03). RV performance parameters (tricuspid annular plane excursion, HR = 0.40; fractional area change, HR = 0.90; and RV peak global longitudinal strain, HR = 1.39) were associated with mortality. These RV performance parameters remained associated in a multiple logistic regression accounting for gestational age and GO status. The overall population had abnormal eccentricity index and pulmonary artery acceleration time to RV ejection time ratio, two markers of PH. CONCLUSION: Patients with omphalocele have increased pulmonary pressure, with GO being worse than non-GO. RV dysfunction at initial echocardiography was significantly associated with mortality.
