Abstract
PURPOSE This study aimed to investigate hematological and cardiac changes after early (ECC) versus delayed cord clamping (DCC) in preterm infants at 24-34 weeks of gestation. METHODS Ninety-six healthy pregnant women were assigned randomly to the ECC (< 10 s postpartum, n = 49) or DCC (45-60 s postpartum, n = 47). Primary endpoint was evaluation of neonatal hemoglobin, hematocrit and bilirrubin levels within the first 7 days after birth. A postpartum blood test was performed in the mother and a neonatal echocardiography in the first week of life. RESULTS We found differences in hematological parameters during the first week of life. On admission, the DCC group had higher hemoglobin levels than the ECC group (18.7 ± 3.0 vs. 16.8 ± 2.4, p < 0.0014) and higher hematocrit values (53.9 ± 8.0 vs. 48.8 ± 6.4, p < 0.0011). Around day 7 of life, hemoglobin levels were also higher in the DCC group compared with the ECC group (16.4 ± 3.8 vs 13.9 ± 2.5, p < 0.005), as was the hematocrit (49.3 ± 12.7 vs 41.2 ± 8.4, p < 0.0087). The need of transfusion was lower in the DCC compared to the ECC (8.5% vs 24.5%; OR: 0.29, 95% CI: 0.09-0.97, p < 0.036). The need for phototherapy was also higher in the DCC (80.9% vs 63.3%; OR: 0.23, 95% CI: 0.06-0.84, p < 0.026). No differences in cardiac parameters or maternal blood tests. CONCLUSION DCC improved neonatal hematological parameters. No changes in cardiac function were found and maternal blood loss did not increase to require transfusion.

Abstract
OBJECTIVE Targeted neonatal echocardiography (TNE) is a real-time cardiac imaging modality used by a hemodynamics program to aid in diagnosis, treatment, and monitoring of neonatal cardiovascular illness. This study aimed to describe trainees' perspectives on existing hemodynamics education and perceived impacts of TNE and hemodynamics services on their education. STUDY DESIGN This was a mixed quantitative and qualitative study that surveyed neonatal-perinatal medicine (NPM) fellow trainees in Canada and the United States, at programs both with and without a hemodynamics service. RESULTS Ninety-two fellows responded to the survey, of whom 24 (26%) were enrolled in a program with an active hemodynamics service, 64 (70%) were training at a program without a hemodynamics service, and 4 (4%) were unsure. Trainees at centers with a hemodynamics service were more satisfied with their cardiovascular physiology education (91 vs. 69%, p = 0.040). Twenty-five percent of all trainees felt they do not have sufficient hemodynamics training to prepare them for independent practice. Areas of knowledge gaps were identified. Bedside teaching combined with didactic teaching was identified as useful means of teaching. CONCLUSION Most trainees believed that TNE and a hemodynamics service are valuable educational assets. Thoughtful curriculum design for real-time and consolidation learning, with specific emphasis on content gaps, should be considered. KEY POINTS · NPM Fellows perceive TNE & Neonatal Hemodynamics service as a valuable educational opportunity.. · Incorporation of TNE/Hemodynamics teaching into NPM curriculum can enrich trainee experience.. · Combining bedside and classroom teaching is key to successful cardiovascular training..

[PMID: 37184647 DOI: 10.1007/s00431-023-05008-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 04/22/2023] [Accepted: 04/27/2023] [Indexed: 05/16/2023]
Abstract
To evaluate clinical practice, neonatologists' attitudes, and the extent of training and accreditation regarding targeted neonatal echocardiography (TnEcho) among Chinese neonatologists. A web-based questionnaire was emailed to 331 neonatologists across China who completed training in subspecialty neonatology. The survey covered various aspects of TnEcho, including the characteristics of clinical practice, attitudes towards its usefulness, and perceived barriers to implementation and training methods. Survey response rate was 68.0% (225/331). Seventy-nine (35.1%) respondents stated that TnEcho was utilized in their NICUs. Most respondents reported the use of echocardiography to evaluate hemodynamic significance of the patent ductus arteriosus (PDA, 94.9%). The eyeballing technique was most used to evaluate left (82.3%) and right (77.2%) ventricular function. Most respondents (87.3-96.2%) positively valued the role of TnEcho in providing timely and longitudinal hemodynamic information to guide cardiovascular care. Access to TnEcho was more likely in centers with on-site pediatric cardiology service (p = .003), larger bed capacity (p = .004), or level IV status (p = .003). Lack of experienced practitioners with echocardiography expertise (88.9%) and accredited training programs (85.8%) was perceived to be the major barrier to implementation. Of concern, most practitioners with TnEcho skills received training in an informal manner through workshops (60.8%) or self-directed learning (54.4%). Conclusions: The use of TnEcho for longitudinal evaluation of infants with hemodynamic instability is growing within Chinese NICUs. There is an urgent need to develop standardized training programs and accreditation for TnEcho which are adapted to the Chinese context.

Abstract
Pulmonary hypertension is an emergency in neonatal intensive care units with high morbidity and mortality. Its timely assessment and management is crucial for intact survival. Over the last couple of decades, there have been significant advances in management and techniques, which have resulted in improved survival. The use of neonatologist-performed echocardiography (NPE) is now increasingly utilized on neonatal intensive care units to understand the pathophysiology of the disease and to direct the treatment to the underlying cause. Its use is now established not only in cases of congenital diaphragmatic hernia and in the newborn with refractory hypoxemia, but also in other conditions such as bronchopulmonary dysplasia and the premature infant with difficulty in oxygenation. The use of NPE, however, requires the availability of trained personnel, equipment, and a close working relationship with pediatric cardiology.

Abstract
BACKGROUND Literature dating back to 1982 supports the use of ultrasound to confirm UVC position as a more reliable method compared to x-ray. The use of ultrasound to confirm UVC position remains infrequent in the NICU. PURPOSE To determine the feasibility of training an NNP in the acquisition and interpretation of a parasternal short-axis (PSAX) image of the heart to confirm UVC position. METHODS A retrospective review of 48 charts evaluated descriptive data using standard technique of an x-ray to confirm UVC placement. An NNP was trained to acquire and interpret a parasternal short-axis (PSAX) cardiac view by a pediatric cardiologist. The NNP independently and prospectively evaluated 21 neonates and determined whether the UVC was in satisfactory or unsatisfactory position. The same image was blindly over-read by the pediatric cardiologist. Agreement between the NNP and pediatric cardiologist interpretations as well as the pediatric cardiologist and radiologist interpretations was evaluated using the κ-test. RESULTS Initial pediatric cardiology interpretation of UVC position showed the UVC to be malpositioned in 66% of neonates (n = 14). NNP and pediatric cardiology interpretations in UVC position had 86% agreement (κ-0.667). Pediatric cardiology (ultrasound) and radiology interpretations (x-ray) in UVC position had 86% agreement (κ-0.69). IMPLICATIONS FOR PRACTICE It is feasible to train NNPs to perform and accurately interpret a single PSAX ultrasound image to determine satisfactory UVC position. IMPLICATIONS FOR RESEARCH Increasing the use of ultrasound to determine satisfactory position of UVCs in the NICU can reduce unnecessary exposure to ionizing radiation in neonates.
