The aim of this study was to explore the application effect of intelligent incubator in neonatal care. We selected the period from January 1, 2018, to December 31, 2020, where there were 100 full-term and premature babies born in a hospital and transferred to the neonatal intensive care unit (NICU) within 1 hour after birth. Before the improved heat preservation, 100 full-term infants in the control group and 100 full-term infants in the intervention group of the intelligent warming box were formed into a full-term infant group for a comparative study. Statistics and comparison of the two groups of term infants and premature infants admitted to the hospital were carried out to assess body temperature and the changes in the incidence of each system. The research found that on comparison of admission body temperature between the control group and the intervention group, with the intervention group in the intelligent heating box, the incidence of hypothermia was significantly lower than that of the control group (95% vs. 37% of full-term infants; 98% vs. 49% of premature babies; there is a statistical significance ( P < 0.05 )). The intelligent heating box can reduce the fluctuation of the newborn’s body temperature, keep the internal environment of newborns stable, and provide suitable conditions for the rapid growth of newborns, suitable for clinical promotion and application.
