What an amazing time spent co-teaching at UBC last week.
It was pretty surreal being back in the same lecture hall where I went to medical school!

Dad always said, "Take a deep breath," but for some neonates, that’s easier said than done.
A 2026 American Family Physician article highlights that while 10% of neonates need respiratory support at birth, 5% require more than just a quick dry and stimulation.
10% admission rate: Transient tachypnea of the newborn is a leading cause of NICU stays.
60-second window: Heart rate and breathing effort must be assessed within the first minute.
Suctioning shift: Routine endotracheal suctioning is no longer recommended.
Stop & Think: Before scrolling down, ask yourself: If a term neonate has a heart rate of 90 beats per minute and isn't breathing well at 60 seconds, what is your next immediate step? Positive-pressure ventilation!
It’s a classic delivery room scenario: the baby is blue, grunting, and tachypneic. Transient Tachypnea of the Newborn is your most likely culprit at term, often showing up within two to six hours of birth, but you must keep the differential broad. This is usually a self-limited "wet lung" issue caused by delayed fluid clearance.
Transient Tachypnea of the Newborn: Supportive care. This is a diagnosis of exclusion.
Respiratory Distress Syndrome: Ground-glass appearance on X-ray. Give surfactant and consider maternal steroids if preterm.
Meconium Aspiration Syndrome: Often results in a barrel chest. Monitor for Persistent Pulmonary Hypertension of the Newborn.
Diagnosis: Return to the basics if stabilization fails. Consider chest radiography if symptoms don't resolve after two hours.
Sepsis/Pneumonia: Ampicillin and Gentamicin are the empiric go-tos.
Pneumothorax: Look for signs on a chest x-ray or decreased air entry on auscultation. Needle decompress if it’s an emergency.
Diaphragmatic Hernia: Scaphoid abdomen is the giveaway. Intubate immediately and avoid bag-mask ventilation.
EXAM TIP: On a SAMP, don't forget that Transient Tachypnea of the Newborn is a diagnosis of exclusion. If the question asks for the "most likely" diagnosis in a term baby with mild distress, it's often TTN, but if it asks for "initial investigations" to rule out danger, you still need to think about sepsis and pneumonia.
