Extracorporeal membrane oxygenation (ECMO) is an important rescue strategy for neonates with severe cardiorespiratory failure, yet its role in the management of hypoxic-ischemic encephalopathy (HIE) remains subject to debate. Historically, clinicians have been reluctant to offer ECMO to infants with significant neurological injury because of concerns related to poor neurodevelopmental outcomes and elevated risk of complications such as hemorrhage and stroke. Over the past two decades, however, accumulating evidence has suggested that many neonates with HIE not only tolerate ECMO well but may also achieve meaningful survival and functional recovery.

Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) is associated with fewer neurological complications and decreased mortality compared to veno-arterial (VA) ECMO in neonatal respiratory failure. The Crescent right atrial (RA) cannula is the only dual-lumen cannula for neonatal VV ECMO designed to have the tip in the right atrium. The purpose of this study is to describe the experience with early use of the Crescent RA cannula.

Multidisciplinary bronchopulmonary dysplasia (BPD) programs provide improved and consistent medical management, care of the developing infant, family support, and smoother transitions in care resulting in improved survival, pulmonary, and extra-pulmonary outcomes. This review summarizes the benefits of interdisciplinary BPD management, as well as strategies for initial programmatic development, program growth, and maintenance at centers across the United States factoring in institutional, provider, and parent reported goals that were derived from a consensus conference on BPD management.

Article Synopsis
  • The study aimed to evaluate short-term outcomes such as mortality and length of stay for extremely low birth weight infants with spontaneous intestinal perforation, comparing three surgical approaches: peritoneal drain (PD), laparotomy after PD (PD-LAP), and straight laparotomy (LAP).
  • Out of 729 identified infants, those treated with PD had lower gestational ages and higher infection rates, with PD associated with higher mortality rates compared to PD-LAP and LAP in initial analysis, but this link was not confirmed in more complex statistical models.
  • Ultimately, the findings suggest that the type of initial surgical approach does not significantly affect mortality or length of stay for these infants, indicating that other factors such

Article Synopsis
  • The study aimed to assess how different international clinical sites manage therapeutic hypothermia (TH) for neonatal hypoxic-ischemic encephalopathy (HIE) and identify areas for standardization.
  • An electronic survey was conducted, gathering responses from 105 sites, primarily from high-income regions, revealing varying practices in eligibility criteria, use of electroencephalography, and sedation methods.
  • The findings indicated significant regional differences in TH management, suggesting that future guidelines should take into account the availability of resources globally.

Objective: Routine blood gas measurements are common in infants with severe bronchopulmonary dysplasia (sBPD) and are a noxious stimulus. We developed a guideline-driven approach to evaluate the care of infants with sBPD without routine blood gas sampling in the chronic phase of NICU care (after diagnosis at 36 weeks PMA).

Study Design: We examined blood gas utilization and outcomes in our sBPD inpatient care unit using data collected between 2014 and 2020.

Objective: This study aimed to examine fetal and neonatal inflammatory and neurologic complications associated with maternal coronavirus disease 2019 (COVID-19) infection.

Study Design: Case-series using a convenience sample of neonates cared for in a large referral-based children's hospital neonatal intensive care unit between September 2021 and May 2022.

Results: We identified seven neonates with exposure to maternal severe acute respiratory syndrome related coronavirus 2 (SARS-CoV-2) and a presentation consistent with inflammatory complications.

  • * Out of 74 patients analyzed, those on extracorporeal life support for more than 5 days were significantly less likely to receive CAR, and many patients exhibited artery issues like stenosis or occlusion during the follow-up period.
  • * The findings indicate that both CAR and ligation result in similar neurodevelopmental outcomes, but the lack of standardized follow-up limits the ability to assess long-term function and informs a need for better risk assessment and monitoring after decannulation
