Why is thermoregulation critical during resuscitation and early NICU care?

• A. A stable temperature reduces metabolic demand and preserves energy for growth and organ function
• B. Temperature has no effect on metabolism
• C. Hypothermia is always best during resuscitation
• D. Hyperthermia improves energy reserves

Answer: (A)

Maintaining a stable body temperature during resuscitation and the early NICU period is essential because it directly influences how much energy the newborn must use just to stay warm. When a baby becomes cool, the body increases metabolic activity to generate heat. That extra energy use boosts oxygen consumption, glucose use, and overall metabolic workload at a time when resources are precious and oxygen delivery may be stressed. If energy is diverted to warmth, less is available for vital processes like tissue repair, organ function, and brain development, increasing the risk of hypoglycemia, acidosis, and perfusion problems. Keeping the infant normothermic minimizes this heat-driven energy drain, preserving energy for growth, organ function, and recovery, and supporting a smoother transition after birth.

Temperature does affect metabolism, so saying it has no effect isn’t accurate. Hypothermia is not beneficial during resuscitation—the extra metabolic demand it creates can worsen outcomes. Hyperthermia isn’t advantageous either and can cause dehydration and other complications.
