Effect of maternal cardiac sound combined with voice stimulation on physical development of premature infants in NICU
Objective To investigate the effect of maternal cardiac sound combined with voice stimulation on physical development of premature infants in neonatal intensive care unit(NICU).Methods Totally 86 premature infants who were treated in the NICU of Children's Hospital of Nanjing Medical University from January 2021 to June 2022 were selected and randomly divided into observation group and control group,with 43 cases in each group.All patients were managed by routine nursing intervention,and those in observation group additionally received maternal cardiac sound combined with voice stimulation.The physical development,milk intake,and parents'satisfaction were compared between the two groups.Results The head circumference in the observation group was significantly greater than that of the control group(on the 5th day after birth:32.76±1.57 cm vs 31.89±1.53 cm;on the 10th day after birth:33.78±1.68 cm vs 32.71±1.71 cm;P＜0.05).The body length in the observation group was significantly longer than that of the control group(on the 5th day after birth:45.98±2.71 cm vs 44.71±2.51 cm;on the 10th day after birth:46.83±2.77 cm vs 45.45±2.63 cm;P＜0.05).The body weight in the observation group was significantly higher than that of the control group(on the 5th day after birth:2 109.59±136.81 g vs 2 002.63±132.27 g;on the 10th day after birth:2 389.71±146.71 g vs 2 215.59±143.28 g;P＜0.05).The milk intake in the observation group was significantly higher than that of the control group(on the 5th day after birth:181.15±38.67 mL vs 141.26±32.66 mL;on the 10th day after birth:371.76±55.97 mL vs 313.57±46.24 mL;P＜0.05).The parents'satisfaction in the observation group was significantly higher than that in the control group(95.35%vs 74.42%,P＜0.05).Conclusion For premature infants in NICU,maternal cardiac sound combined with voice stimulation can optimize physical development,increase milk intake during hospitalization,and improve parents'satisfaction.
