Dr. Colleen Brennan, an academic neonatologist at Washington University, shares her expertise on the critical first hours of a newborn’s life. She discusses recognizing respiratory distress, effective resuscitation techniques, and the challenges of neonatal transitions. Insights into the management of neonatal blood glucose levels are provided, along with the importance of monitoring oxygen after birth. She also reflects on balancing a medical career with motherhood, emphasizing the need for self-kindness in both personal and professional realms.
Dr. Colleen Brennan underscores the urgency of promptly identifying respiratory distress and the critical interventions required for neonatal resuscitation.
The podcast highlights the role of delayed cord clamping in optimizing a newborn's circulation and respiratory function post-delivery.
Brennan emphasizes the impact of social determinants on neonatal health outcomes, calling for equitable healthcare access and awareness of systemic biases.

Specialty Care in the Newborn Nursery
Dr. Colleen Brennan discusses the crucial role of specialty care in the newborn nursery, focusing on the immediate management of newborns requiring resuscitation. She emphasizes the importance of timely interventions, such as recognizing signs of neonatal apnea, which often necessitates positive pressure ventilation. Dr. Brennan illustrates the steps required during resuscitation, detailing the equipment and techniques that healthcare providers must use to ensure the baby's lungs are adequately inflated. This segment covers critical clinical skills and knowledge that can significantly influence outcomes in newborn care.
Physiological Changes at Birth
The podcast delves into the various physiological adaptations that occur in a newborn during the transition from intrauterine to extrauterine life. Dr. Brennan explains the significance of delayed cord clamping and its impact on the newborn's blood circulation and respiratory function. She outlines the expected heart rate and oxygen saturation levels in the immediate minutes after birth, noting that around 90% of babies manage this transition well without assistance. However, she points out that certain conditions, such as a scheduled C-section, can increase the likelihood of respiratory distress due to the lack of labor-related physiological processes.
Managing Neonatal Hypoglycemia
Hypoglycemia in newborns, particularly those born to diabetic mothers, is addressed with a focus on its causes and management strategies. Dr. Brennan clarifies that hypoglycemia is characterized by blood glucose levels below 40 mg/dL in the first few hours of life and highlights common symptoms, like irritability and difficulty feeding. For babies experiencing hypoglycemia, early interventions include oral dextrose gel or IV dextrose administration, which helps stabilize blood sugar levels. The podcast stresses the importance of monitoring blood glucose closely in the vulnerable population of infants of diabetic mothers.
Transitional Physiology and Common Conditions
The discussion emphasizes the common transitional conditions newborns may face, such as transient tachypnea of the newborn (TTN) and their management. Dr. Brennan describes TTN as a condition resulting from retained fetal lung fluid, typically resolving itself within 24 hours. The characteristics of TTN include mild respiratory distress without significant hypoxia, and she reassures that many babies can be monitored closely before any significant interventions are needed. This segment encourages healthcare providers to understand the physiological norms of newborns to differentiate between normal transitional adaptations and concerning symptoms.
Addressing Social Determinants in Neonatal Care
Dr. Brennan highlights the influence of social determinants on neonatal outcomes, particularly for infants of color and those from low-income backgrounds. She discusses how access to prenatal care directly affects maternal and infant health, underlining disparities in outcomes across different demographic groups. The importance of addressing unconscious biases and ensuring equitable healthcare access for all mothers and babies is stressed. This insight urges healthcare providers to consider the broader social context when caring for newborns, reinforcing the need for systemic interventions to improve health equity.
Dr. Colleen Brennan, academic neonatologist at Washington University and director of neonatal outreach, walks us through the first few hours of a baby’s life when things don’t go as planned! She covers critical topics like recognizing respiratory distress and apnea in a neonate, practical tips for corrective steps in newborn resuscitation, how low is too low in neonatal blood glucose, and when to think about etiologies outside of normal transitional physiology!
