Objectives: To determine whether rate of severe intraventricular hemorrhage (IVH) or death among preterm infants receiving placental transfusion with UCM is noninferior to delayed cord clamping (DCC).

Methods: Noninferiority randomized controlled trial comparing UCM versus DCC in preterm infants born 28 to 32 weeks recruited between June 2017 through September 2022 from 19 university and private medical centers in 4 countries. The primary outcome was Grade III/IV IVH or death evaluated at a 1% noninferiority margin.

Objective: This study aimed to determine whether outcomes differed between infants enrolled in the PREMOD2 trial and those otherwise eligible but not enrolled, and whether the use of waiver effected these differences.

Study Design: The multicenter PREMOD2 (PREmature infants receiving Milking Or Delayed cord clamping) trial was approved for waiver of antenatal consent by six of the nine sites institutional review boards, while three sites exclusively used antenatal consent. Every randomized subject delivered at a site with a waiver of consent was approached for postnatal consent to allow for data collection.

Objective: To evaluate changes in cerebral oxygenation, peripheral arterial oxygenation, respiratory status, and administered fraction of inspired oxygen during the first 10 minutes of life in premature infants receiving umbilical cord milking compared with delayed cord clamping (DCC).

Study Design: Premature infants born at 23 to 27 weeks of gestation were randomized to umbilical cord milking or DCC. A near infrared spectroscopy sensor, pulse oximeter, and electrocardiogram electrodes were placed.

Background And Objectives: There are no US Food and Drug Administration-approved therapies for neonatal seizures. Phenobarbital and phenytoin frequently fail to control seizures. There are concerns about the safety of seizure medications in the developing brain.

Objective: This study examined patterns of care after birth in newborns treated with therapeutic hypothermia to identify remediable causes for the poorer outcomes observed in outborn infants.

Study Design: This was a secondary analysis of 150 newborns (68 outborn) prospectively enrolled at our center in the Vermont Oxford Neonatal Encephalopathy Registry from January 2008 to October 2016.

Results: The 5-minute Apgar's score and cord pH value did not differ, but cord blood gases were obtained far less frequently in outborns ( = 0.

Article Synopsis
  • Umbilical cord milking may be a viable alternative to delayed umbilical cord clamping for preterm infants, potentially offering similar benefits without postponing immediate care.
  • A noninferiority clinical trial involving 540 preterm infants from multiple medical centers aimed to compare the effects of these two methods on rates of death and severe intraventricular hemorrhage.
  • Results indicated that 12% of infants in the umbilical cord milking group faced negative outcomes versus 8% in the delayed clamping group, though the difference was not statistically significant.

Purpose: Continuous video electroencephalography (cEEG) monitoring is the recommended gold standard of care for at-risk neonates but is not available in many Neonatal Intensive Care Units (NICUs). To conduct a randomized treatment trial of levetiracetam for the first-line treatment of neonatal seizures (the NEOLEV2 trial), we developed a monitoring infrastructure at five NICUs, implementing recent technological advancements to provide continuous video EEG monitoring and real-time response to seizure detection. Here, we report on the feasibility of providing this level of care.

Objective: To determine whether monitoring cerebral oxygen tissue saturation (StO) with near-infrared spectroscopy (NIRS) and brain activity with amplitude-integrated electroencephalography (aEEG) can predict infants at risk for intraventricular hemorrhage (IVH) and death in the first 72 hours of life.

Study Design: A NIRS sensor and electroencephalography leads were placed on 127 newborns <32 weeks of gestational age at birth. Ten minutes of continuous NIRS and aEEG along with heart rate, peripheral arterial oxygen saturation, fraction of inspired oxygen, and mean airway pressure measurements were obtained in the delivery room.

Background: The seventh edition of the American Academy of Pediatrics Neonatal Resuscitation Program recommends the use of a cardiac monitor in infants that need resuscitation. Previous trials have shown that EKG heart rate is available before pulse rate from a pulse oximeter. To date no trial has looked at how the availability of electrocardiogram (EKG) affects clinical interventions in the delivery room.

Over the past decade, there have been several studies and reviews on the importance of providing a placental transfusion to the newborn. Allowing a placental transfusion to occur by delaying the clamping of the umbilical cord is an extremely effective method of enhancing arterial oxygen content, increasing cardiac output, and improving oxygen delivery. However, premature and term newborns who require resuscitation have impaired transitional hemodynamics and may warrant different methods to actively provide a placental transfusion while still allowing for resuscitation.

Objective: To assess whether providing ventilation during delayed cord clamping (V-DCC) increases placental transfusion compared with delayed cord clamping alone (DCC only).

Study Design: Inborn premature infants (23-31 weeks' gestational age) were randomized to receive at least 60 seconds of V-DCC (initial continuous positive airway pressure) with addition of positive pressure ventilation if needed) or without assisted ventilation (DCC only). For the DCC-only group, infants were dried and stimulated by gently rubbing the back if apneic.

Background: A duration of 30 seconds has been shown to improve the success rate of intubation attempts without any decompensation. There is limited data regarding the detrimental effects of prolonged intubation attempts in preterm infants. The aim was to determine the effect of prolonged intubation attempts on heart rate and oxygen saturation in preterm infants.

Background: Near-infrared spectroscopy (NIRS) has the potential to continuously and noninvasively monitor intestinal function. This technology may be valuable because among neonates, intestinal maturity is highly variable and difficult to assess based solely on clinical signs. The aim of this study was to determine if there is an association between NIRS-based StO2 measurements and peristaltic activity assessed by transabdominal ultrasonography (US).

Background: To date no study has attempted to continuously evaluate changes in hemodynamics during delayed cord clamping in humans. We aimed to demonstrate 1. the feasibility of measurements of hemodynamics during delayed cord clamping and 2.

Mothers of preterm infants are at risk for poor sleep quality, which may adversely affect their health, maternal-infant attachment, and infant caretaking activities. This study examined the relationship of an 8-week relaxation guided imagery intervention on sleep quality and the association between sleep quality and maternal distress (perceived stress, depressive symptoms, and state anxiety) in 20 mothers of hospitalized preterm infants. Mothers received a CD (compact disc) with three 20-minutes recordings and were asked to listen to at least 1 recording daily for 8 weeks.

Article Synopsis
  • The study aimed to create a standardized definition of Bronchopulmonary Dysplasia (BPD) to minimize variation in its diagnosis across different neonatal centers by implementing a timed room-air challenge.
  • Researchers assessed 1598 premature infants at 36 weeks' postmenstrual age using both a clinical definition (based on oxygen supplementation) and a physiologic definition (involving a room-air challenge).
  • The clinical method identified BPD in 35.0% of the cases, while the physiologic method diagnosed it in 25.0%, indicating potential benefits to using a physiologic approach for consistency.
