When is the risk of hypothermia the highest in newborns?

• A. During the first hour after birth
• B. In the delivery room
• C. After being discharged from the hospital
• D. During the first week of life

Answer: (B)

The highest risk of hypothermia in newborns occurs in the delivery room immediately after birth. This critical time is characterized by various factors that can contribute to temperature loss, including exposure to cool ambient air, wet skin after delivery, and the inability of newborns to generate sufficient heat due to their limited muscle mass and immature metabolic systems.

Newborns are particularly vulnerable to hypothermia because they have a high surface area-to-volume ratio, which allows them to lose heat rapidly. In the delivery room, they may be in an environment that is not optimally heated and may also be exposed to drafts or cooler temperatures.

Therefore, it is crucial to ensure that newborns are quickly dried, swaddled in warm blankets, and placed under a radiant warmer right after birth to maintain their body temperature. While the risk of hypothermia can exist at various stages, including after discharge or during the first week of life, the immediacy of conditions in the delivery room accentuates the threat of hypothermia right after birth.
