Abstract

Objective To explore the interventional effect of olfactory soothing combined with maternal voice stimulation on the sleep of hospitalized preterm infants. Methods A total of 90 hospitalized premature infants in the neonatal intensive care unit of a tertiary hospital in Yunnan Province from August 2023 to March 2024 were selected. Using a random number table method, they were randomly divided into two groups: the olfactory comfort combined with mother's voice stimulation group and the control group, with 45 cases in each group. The control group received routine gentle pat comfort intervention, while the olfactory comfort combined with mother’ s voice stimulation group was wiped with 5 drops of breast milk on a sterile cotton swab 1～2 cm away from the nostrils of premature infants. At the same time, the mother's voice was played 15 cm away from the premature infants. During playback, a decibel testing instrument was used to adjust the volume of the mother's voice to about 35～40 decibels. The playback time period was from 08:00 to 08:20, 14:00 to 14:20, 20:00 to 20:20. Each playback period is 20 minutes, and the mother's voice is played while providing olfactory comfort once. Two groups of hospitalized premature babies were compared for 24-hour total sleep time, sleep onset time, daytime sleep time, nighttime sleep time, and number of nighttime awakenings. Results Compared with the control group, the olfactory comfort combined with mother's voice stimulation group had significantly longer daytime sleep time, nighttime sleep time, and 24-hour total sleep time, significantly shorter sleep latency time, and significantly fewer nighttime awakenings, with statistical significance （P < 0.05）. Conclusion The combination of olfactory comfort and maternal voice stimulation can effectively improve the sleep quality of hospitalized premature infants, providing a reference method for sleep intervention in premature infants.
