A 28-week gestational age infant is born to heroin-using mother; the infant's respiratory depression would be best managed by?

• A. 0.1 mg naloxone IV through an umbilical artery catheter
• B. 0.1 mg naloxone IM in the newborn's thigh muscle
• C. 0.1 mg naloxone down the endotracheal tube
• D. None of the above

Answer: (D)

Opioid exposure in utero can depress a newborn’s breathing, and the first-line approach is careful supportive care rather than routine antidote administration. For a 28-week preterm infant, the priority is maintaining adequate ventilation and oxygenation, providing warmth and glucose as needed, and close monitoring. Naloxone can reverse opioid effects, but in neonates it is not given routinely because rapid reversal can provoke withdrawal symptoms, instability, and worsened respiratory effort in a delicate preterm infant. If naloxone is ever considered, it should be given only after establishing reliable airway and ventilation, and in small, titrated doses via an intravenous route—not as a fixed dose through an endotracheal tube, intramuscular injection, or through an umbilical artery catheter. Given these considerations, none of the listed single-dose routes and approaches is the best initial management. The appropriate plan centers on supportive respiratory care, with naloxone reserved for selective, carefully monitored use if persistent, severe respiratory depression remains after adequate ventilation.
