Analysis of the effects of maternal sound stimulation combined with white noise interference on pain and nervous system development of neonates in NICU
Objective To analyze the effects of maternal sound stimulation combined with white noise interference on pain and nervous system development of neonates in neonatal intensive care unit(NICU).Methods 150 neonates in NICU were divided into a combined group(n=75,maternal sound stimulation combined with white noise interference based on the control group)and a control group(n=75,routine perinatal intervention)according to random number table method.Both groups were compared in terms of pain score,heart rate before heel blood collection,and abnormal rate of infant neurological motor assessment(INMA)in neonates at 0-1 years of age.Results There was no significant difference in pain scores between the two groups before heel blood collection(P>0.05).The pain scores during the heel blood collection and recovery period in the combined group were(6.01±1.12)and(3.21±0.65)points,which were lower than(7.65±1.21)and(4.51±0.81)points in the control group(P<0.05).There was no significant difference in heart rate before heel blood collection and 3 min after blood collection(P>0.05).The heart rate was(151.23±13.51)beats/min in the combined group 1 min after blood collection,which was significantly lower than(165.23±10.56)beats/min in the control group,and the difference was significant(P<0.05).After follow-up,there was no significant difference in the abnormal rate of INMA in neonates at 1,2 and 3 months of age between the two groups(P>0.05).The abnormal rates of INMA in neonates at 4 and 5 months of age in the combined group were 16.00%and 14.67%,which were lower than 34.67%and 33.33%in the control group,the difference was significant(P<0.05).Conclusion Maternal sound stimulation combined with white noise interference for neonates in NICU can help relieve pain and stabilize heart rate,and has positive significance for the development of the nervous system.
