Abstract:
Objective:To evaluate the effectiveness of mother's breast milk odor on alleviating operational pain in newborns.Methods:The randomized controlled trial on the effect of mother's breast milk odor in operational pain of newborns was searched through computers in PubMed, Embase, Cochrane Library, Web of Science, CINAHL, China National Knowledge Infrastructure (CNKI) and Wanfang Data. The search period was from database establishment to December 12, 2022. Two evaluators independently selected literature and extracted data based on the inclusion and exclusion criteria, and used the risk of bias of Cochrane Collaboration handbook to conduct methodological quality evaluations of the included study. R 4.1.0 statistical software was used for meta-analysis.Results:A total of 18 articles were included, including 1 424 newborns. The Meta-analysis results showed that compared with the control group, the mother's breast milk odor group showed a decrease in the degree of pain, a decrease in heart rate, and an increase in blood oxygen saturation during the painful procedure in newborns, with statistically significant differences ( P<0.05) . There was no statistically significant difference in crying time ( P>0.05) . Compared with the control group, the mother's breast milk odor group showed a statistically significant decrease in the degree of pain and heart rate, an increase in blood oxygen saturation, and a decrease in salivary cortisol in newborns during the recovery period after painful procedures ( P<0.05) . Conclusions:The mother's breast milk odor can alleviate operational pain in newborns, reduce heart rate and salivary cortisol, and increase blood oxygen saturation in newborns. The sample size included in the study is small, and there are also differences in the duration and methods of intervention among different studies. There is still a need for rigorous design and large-scale research to verify.
