Background: In this case report, we describe a very rare case of severe limb ischemia due to an arterial embolus caused by an aneurysm of the oval foramen in a term-born infant that occurred in the first few hours after birth.
Case Presentation: A newborn male Caucasian patient presented on the maternity ward with ischemia of the right foot. Ischemia was treated with nitroglycerin spray and low-molecular-weight heparin in therapeutic dosage.
Article Synopsis
- The study aimed to evaluate if using a respiratory function monitor (RFM) during positive pressure ventilation (PPV) improves the percentage of inflations with the desired tidal volume in extremely preterm infants.
- Conducted as a clinical trial in neonatal intensive care units across 6 countries, infants were randomly assigned to either have the RFM visible or not while receiving PPV, with a focus on comparing the percentage of inflations within the target range of 4-8 mL/kg.
- Results showed no significant difference in the percentage of correct inflations between the two groups; however, the group with visible RFM had a lower incidence of serious brain conditions, indicating possible benefits despite the primary outcome not being met.
Objective: To assess delivery room management of infants born preterm at 4 Level III perinatal centers in 3 European countries.
Study Design: This was a prospective, multicenter observational study. Management at birth was video-recorded and evaluated (Interact version 9.
Background: Although little data are available concerning safety for newborns, family-centered caesarean sections (FCS) are increasingly implemented. With FCS mothers can see the delivery of their baby, followed by direct skin-to-skin contact. We evaluated the safety for newborns born with FCS in the Leiden University Medical Center (LUMC), where FCS was implemented in June 2014 for singleton pregnancies with a gestational age (GA) ≥38 weeks and without increased risks for respiratory morbidity.

Study Design: Recorded resuscitations of very preterm infants receiving PPV or CPAP after birth were analyzed retrospectively. The respiratory effort (minute volume and recruitment breaths [>8 mL/kg], heart rate, oxygen saturation, and oxygen requirement were analyzed for the first 2 minutes and in the fifth minute after birth.
