Thermal environment change in growing premature infants: effect on general somatic growth and subcutaneous fat
Insights
Moving premature infants to cribs earlier, around 1,600-1,900 gm, enhanced subcutaneous fat deposition. This change improved cold resistance without affecting weight gain or thermal stability.
Area of Science:
- Neonatal care
- Infant physiology
- Developmental pediatrics
Background:
- Premature infants often require incubators for thermal regulation.
- Transitioning to a less controlled environment is a critical developmental step.
- Optimizing this transition can impact infant growth and adaptation.
Purpose of the Study:
- To investigate the effects of transitioning premature infants from incubators to cribs at different weights.
- To assess the impact on infant growth, thermal stability, and subcutaneous fat deposition.
- To determine if a cooler environment influences cold resistance in growing premature infants.
Main Methods:
- Fourteen healthy premature infants were divided into two groups based on weight for transition from incubator to crib (Group A: 1,600-1,700 gm; Group B: 1,800-1,900 gm).
- Measurements of growth, abdominal temperature, and skinfold growth were taken before and after the transition.
- Environmental temperature was reduced by 5°C post-transition.
Main Results:
- All infants tolerated the transition well, with no significant drop in abdominal temperature.
- Weight gain rates correlated solely with energy intake and did not differ between groups.
- A significant increase in skinfold growth rate was observed after moving to the crib environment.
Conclusions:
- Transitioning premature infants weighing over 1,600 gm to a cooler environment may promote increased subcutaneous fat deposition.
- Enhanced subcutaneous fat may contribute to improved cold resistance in growing premature infants.
- Early transition to a crib environment appears safe and potentially beneficial for premature infant development.
Abstract:
Fourteen growing, healthy premature infants were moved from heated incubators to cribs at different points in their growth. Group A (six babies) was moved when babies reached a weight of 1,600 to 1,700 gm; group B (eight babies) when babies reached a weight of 1,800 to 1,900 gm. All other conditions of rearing were kept the same. The effect on their growth and thermal stability was measured during the week before and after the temperature change. All infants tolerated the change well. There was no drop in abdominal temperature in an environment cooler by 5 C. The rate of weight gain correlated with gross energy intake only and did not differ within or between the two groups. The rate of growth of the skinfolds increased dramatically after the infants were moved from the incubator. A cooler environment in a growing premature infant (weight greater than 1,600 gm) may promote faster deposition of subcutaneous fat. This might be an important factor in efficient gain in cold resistance.
