Objective To explore the impact of maternal voice stimulation on the extremely premature infants based on augmented reality sound simulation technology. Methods Seventy-six extremely premature infants born in a grade-A tertiary hospital in Guangzhou between January 2021 and June 2022, were divided into an observation group and a control group, each of 38, according to a random number table. Both groups were given routine nursing, while the observation group was additionally provided with maternal voice stimulation based on augmented reality sound simulation technology for 14 days. Then, the growth and development indicators, heart rate, rehabilitation effect and incidence of complications were compared between the two groups. Results There were statistically significant differences in heart rate between the two groups in terms of time, groups and interaction effects(Ftime=10.318,P<0.001; Fgroup=7.399,P<0.001;Fintergroup=9.281,P<0.001), and the number of days receiving total enteral nutrition was shorter than the latter (t=2.621, P=0.011). However, after the intervention, no significant differences were found between the two groups in the body length, head circumference,body weight, ventilator use time, oxygen use time, hospital stay and complication rate(P>0.05). Conclusion Maternal voice stimulation based on augmented reality sound simulation technology has a good effect on the extremely preterm infants, which can stabilize their heart rate and help them to reach full intestinal feeding as soon as possible.
