Each explainer pairs the reel with a written summary: what researchers asked, what they did, what they found, and where the evidence stops. Every page links to the original papers.
The 1972 Liggins and Howie trial that put antenatal steroids on the map, and what five decades of trials added.
Respiratory · Pharmacology & prophylaxis
In the preterm chest, every ventilator change is also a change to preload, afterload and pulmonary vascular resistance.
Respiratory · Hemodynamics
5.2 million US newborns, rising refusal, and what happened to infants who did not get vitamin K at birth.
Pharmacology & prophylaxis
Why inhaled nitric oxide can rescue one hypoxic preemie with pulmonary hypertension and not the next.
Cardiac · Hemodynamics
Bubble CPAP, RAM cannula, prongs and masks: the device and interface shape the pressure that actually reaches the airway.

0.9% saline is the default NICU bolus. A look at the chloride it carries and when a balanced crystalloid may fit better.
Fluids
A higher platelet transfusion threshold seemed safer. In preterm infants, the trial found the opposite.
Transfusion
A trial stopped early for a safety signal, and what it found in extremely preterm and older preterm infants.
Delivery room
Two large trials asked whether higher red-cell transfusion thresholds protect the brains of extremely low-birth-weight infants.
Transfusion
Two trials tested early ibuprofen for the patent ductus arteriosus in extremely preterm infants. Neither found the benefit many expected.
