![]() ![]() To date, however, strategies to prevent neonatal hypothermia during transport to the NICU have not been comprehensively considered. Inadequate warming during transport from the delivery or operating room to the NICU through cool ambient-temperature passageways is a potentially modifiable cause of hypothermia upon admission to the NICU 14. Therefore, more reliable methods to prevent neonatal hypothermia are needed 17, including during transportation to the NICU. Despite these guidelines, neonatal hypothermia at the time of admission to the NICU remains an issue of concern in practice 1, 2, 13, 14, 15, 16. The European Resuscitation Council 2021 Guidelines make more specific recommendations for ambient temperatures of 23–25 ☌ for neonates of 28–32 weeks of gestation and > 25 ☌ for neonates of ≤ 28 weeks of gestation 12. The World Health Organization and a 2013 randomized controlled trial recommended an ambient temperature of 25 ☌ for delivery and operating rooms used for neonatal care 10, 11, with temperatures of 23–25 ☌ recommended in the 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations 8. Therefore, various measures are used in the NICU to prevent neonatal hypothermia, including control of environmental temperature use of warm blankets, plastic wrapping, caps, and thermal mattresses and skin-to-skin care 8, 9. In the first 10–20 min at birth, no intervention to prevent neonatal heat loss may make the neonatal body temperature fall by 2–4 ☌ 7. Therefore, it is more important to maintain the body temperature while transporting very low-birthweight neonates. Second, they easily lose heat because they have a relatively large body surface area with thin subcutaneous tissue necessary for thermal insulation 6, 7. ![]() For example, they cannot shiver, do not have enough vascular control, and have low glycogen levels and brown fat storage 6, 7. First, they lack a heat production mechanism. Very low-birthweight neonates easily decrease their body temperature. ![]() Additionally, hypothermia can cause acidosis, hypoglycemia, and hypoxia 5. In particular, a 1 ☌ decrease in body temperature on admission to the NICU is associated with a 28% increase in mortality and an 11% increase in the probability of late-onset sepsis for extremely low-birthweight neonates 4. Hypothermia in newborns in the neonatal intensive care unit (NICU) increases the risk of health complications and mortality and, thus, must be prevented 1, 2, 3. Therefore, snap-open access port covers provide an option to maintain a constant temperature within the transport incubator, which may lower the risk of neonatal hypothermia. The incubator temperature decreased as a function of decreasing room temperature only for the open condition, with no significant difference between the closed and covered conditions. The temperature decrease inside the incubator was greater for the open than for the closed or covered access port conditions at all three 4 ☌-increasing room temperatures ( p < 0.05). We repeated the same experiments three times. ![]() The automatic temperature control of the incubator was set to 37 ☌ for all conditions. The change in temperature inside the transport incubator was evaluated over a 15-min period at three ambient room temperatures (20 ☌, 24 ☌, and 28 ☌), as well as for three snap-open access port conditions: closed, where ports are closed open, where the two ports on one side are open and covered, where the two ports on one side are open but a cover is used. This study aimed to evaluate the effectiveness of using covers over snap-open access ports of a transport incubator to maintain the temperature within. Hypothermia in newborns increases the risk of health complications and mortality. ![]()
