Immediately following birth, the newborn's metabolic rate increases , and its oxygen consumption increases.
Preterm babies' basal metabolic rates are lower than those of full-term babies' and rise more slowly over the first month of life outside the womb. Preterm infants' metabolic rates (1000–2000 g, 2–31 days old) did not exceed 40 kcal/kg/d during thermoneutrality (MESTYAN, JARAI and FEKETE, 1968).
Children also tire easily. If they don't get enough calories, their rapid metabolisms render them particularly susceptible to sickness and stunted growth. They may also require more frequent doses since their cells may digest medications more quickly than those of adults.
The average resting metabolic rate for adults was 4.93 1.09 and for children it was 3.91 0.98 kJ/min. Caution is necessary due to body size variations. Hence, Immediately following birth, the newborn's metabolic rate increases , and its oxygen consumption increases.
