Newborn Health and Neonatal Resuscitation
Core concepts
Neonatal resuscitation follows a stepwise algorithm. At birth, ask three questions: term gestation? good tone? breathing or crying? If yes, provide warmth, dry, and routine care with the mother. If no, begin the initial steps: warm, dry, stimulate, position the head, and clear the airway only if needed. Assess breathing and heart rate; if apneic or heart rate below 100, start positive pressure ventilation (PPV). Use pulse oximetry to guide oxygen. If heart rate remains below 60 after effective ventilation, begin chest compressions (3:1 ratio with ventilations) and consider epinephrine if still below 60. Understand thermoregulation, hypoglycemia screening, jaundice assessment, and newborn danger signs (poor feeding, lethargy, respiratory distress, hypothermia).
Traps
Questions often test the compression-to-ventilation ratio (3:1) and the heart rate threshold for starting compressions (below 60). Another trap: giving oxygen to a preterm newborn too liberally - use blended oxygen guided by oximetry. Also watch the misconception that routine suctioning is required; suction only when the airway is obstructed or PPV is needed.
Worked rule of thumb
Ventilation is the most important and effective step in neonatal resuscitation. If the heart rate is not rising, first check that ventilation is effective (chest movement, mask seal, repositioning) before adding compressions or drugs.
Exam strategy
In scenarios, sequence matters: dry and stimulate, then assess, then ventilate, then compress, then medicate. Choose the answer that reflects the next correct step, not the final step.
