Importance: Providing assisted ventilation during delayed umbilical cord clamping may improve outcomes for extremely preterm infants.

Objective: To determine whether assisted ventilation in extremely preterm infants (23 0/7 to 28 6/7 weeks' gestational age [GA]) followed by cord clamping reduces intraventricular hemorrhage (IVH) or early death.

Design, Setting, And Participants: This phase 3, 1:1, parallel-stratified randomized clinical trial conducted at 12 perinatal centers across the US and Canada from September 2, 2016, through February 21, 2023, assessed IVH and early death outcomes of extremely preterm infants randomized to receive 120 seconds of assisted ventilation followed by cord clamping vs delayed cord clamping for 30 to 60 seconds with ventilatory assistance afterward.

Purpose Of Review: To discuss a structured training process that can be used to guide curricula development in procedural skills in neonatal perinatal medicine training programs.

Recent Findings: Achieving proficiency in life savings skills such as neonatal endotracheal intubation does not occur for all graduates of neonatal perinatal medicine programs. Innovations in procedural skills training offer opportunities to enhance the current educational environment and improve competency at all levels of learning.

Background: Respiratory distress is common during transition after birth, but the effect of continuous positive airway pressure applied in the delivery room has not been systematically evaluated in spontaneously breathing term and ≥34 weeks' gestation infants.We aimed to compare delivery room continuous positive airway pressure with no delivery room continuous positive airway pressure for term and ≥34 weeks' gestation newborn infants at birth.

Methods: Information sources: Medline, Embase, Cochrane Databases, Database of Abstracts of Reviews of Effects, and Cumulative Index to Nursing and Allied Health Literature.

Resuscitation guidelines are developed and revised by medical societies throughout the world. These guidelines are increasingly based on evidence from preclinical and clinical research. The International Liaison Committee on Resuscitation reviews evidence for each resuscitation practice and provides summary consensus statements that inform resuscitation guideline committees.

Term newborn infants without significant medical problems usually transition from fetal to newborn life without medical assistance. Infants requiring therapy often need care in a neonatal intensive care unit as opposed to a well-baby unit. Infants with unclear physiologic status or disease that may require therapies in the immediate newborn period may benefit from a period of observation with close monitoring before admission to a well-baby unit.

Neonatal resuscitation is an event that can cause high stress among healthcare professionals (HCPs) and is frequently associated with medical errors. Improving patient safety and reducing errors requires a concerted effort with a plan for improvement. Video can be used as a component of the improvement process at several points including standardizing educational information, assessing learner knowledge and skills during simulation, and assessing individual and team performance during actual neonatal resuscitations.

Objectives: The identification of hydrocephalus in infants by pediatric emergency medicine (PEM) physicians using cranial point-of-care ultrasound (POCUS) has not been evaluated. We aimed to conduct a pilot/proof-of-concept study to evaluate whether PEM physicians can identify hydrocephalus (anterior horn width >5 mm) in 15 infants (mean 69 ± 42 days old) from the neonatal intensive care unit using POCUS. Our exploratory aims were to determine the test characteristics of cranial POCUS performed by PEM physicians for diagnosing hydrocephalus and the interrater reliability between measurements made by the PEM physicians and the radiologist.

Objective: To determine if preterm infants with moderate respiratory distress syndrome on continuous positive airway pressure (CPAP) who received surfactant via a laryngeal mask airway (LMA) would have a decreased rate of intubation and mechanical ventilation compared with those on CPAP who did not receive surfactant.

Study Design: In this prospective, multicenter, randomized controlled trial, 103 premature infants 28-35 weeks gestation, ≥1250 g and ≤36 hours old on CPAP requiring fraction of inspired oxygen 0.30-0.

Objective: To evaluate whether neonates exposed to multiple intubation attempts within the first 4 days after birth have an increased incidence of intraventricular hemorrhage (IVH).

Study Design: This is a retrospective cohort study of infants intubated during the first 4 days after birth. Infants had birth weights (BWs) less than 1500 g and were admitted to the neonatal intensive care unit (NICU) at the University of California, San Diego, between January 1, 2005, and July 30, 2009.

Objective: To determine whether umbilical cord milking (UCM) improves systemic blood flow and reduces neonatal morbidities compared with immediate cord clamping (ICC).

Study Design: Women admitted to a tertiary care center and delivering before 32 weeks' gestation were randomized to receive UCM or ICC. Three blinded serial echocardiograms were performed in the first 2 days of the infant's life.

Objectives: To investigate the utility of continuous quantitative end-tidal CO2 (Etco2) monitoring for managing assisted ventilation in the delivery room (DR).

Study Design: This is a prospective randomized controlled trial. Infants who received positive pressure ventilation (PPV) were randomized to a control versus a monitored arm.

Despite advances in the understanding of fetal and neonatal physiology and the technology to monitor and treat premature and full-term neonates, little has changed in resuscitation rooms. The authors' vision for the Fetal and Neonatal Resuscitation and Transition Suite of the future is marked by improvements in the amount of physical space, monitoring technologies, portable diagnostic and therapeutic technologies, communication systems, and capabilities and training of the resuscitation team. Human factors analysis will play an important role in the design and testing of the improvements for safe, effective, and efficient resuscitation of the newborn.

The immediate newborn transition is a time of great physiologic adjustments and many infants need assistance to make a successful transition to newborn life. Assisted ventilation is the most important intervention performed during this transitional period. Noninvasive ventilation is a necessary skill for all pediatric providers because it is the most frequently required lifesaving measure provided in the delivery room.

Neonatal asphyxia is associated with multi-organ hypoxia-ischemia and subsequent dysfunction. The cardiovascular system is frequently affected, causing signs of shock and complicating the neonatal circulatory transition. Hypothermia therapy can improve outcome from neonatal asphyxia without adversely affecting cardiovascular stability.

Objective: In this study of preterm neonates of <32 weeks, we prospectively compared the use of room air versus 100% oxygen as the initial resuscitation gas.

Methods: A 2-center, prospective, randomized, controlled trial of neonates with gestational ages of 23 to 32 weeks who required resuscitation was performed. The oxygen group was initially resuscitated with 100% oxygen, with decreases in the fraction of inspired oxygen after 5 minutes of life if pulse oxygen saturation was >95%.

Objective: The purpose of this work was to investigate whether using a muscle relaxant would improve intubation conditions in infants, thereby decreasing the incidence and duration of hypoxia and time and number of attempts needed to successfully complete the intubation procedure.

Patients/methods: This was a prospective, randomized, controlled, 2-center trial. Infants requiring nonemergent intubation were randomly assigned to receive atropine and fentanyl or atropine, fentanyl, and mivacurium before intubation.

Colorimetric carbon dioxide detectors are useful indicators of proper endotracheal tube placement. We have found that they also are helpful during bag and mask ventilation as an indicator of a patent airway. In this report, we describe our experience with these devices for use during preintubation airway stabilization as observed during videotaped performances from a prospective, randomized trial of intubation premedication.
