Abstract

This study was a randomized-controlled trial aiming to determine the effects of a lactation-promotion program combined with listening to music on milk ejection and lactation time among mothers with cesarean section. The sample group comprised 50 mothers after cesarean section, purposively selected according to inclusion criteria. Through blocked randomization by computer, the control group (n=26) received standard care, while the experimental group (n=24) received the lactation-promotion program combined with listening to music. The instruments used in this study consisted of (1) the intervention instruments including a breastfeeding-promotion manual for mothers after cesarean section and music files on a mobile phone with wireless headphones, (2) the experimental-control instruments including a self-recording form of listening to music, and (3) the data collection instruments comprising 3 forms: (3.1) the personal data and obstetric record form, (3.2) the milk ejection assessment form, and (3.3) the lactation time record form. The milk ejection assessment form and the lactation time record form were content validated by three experts yielding content validity indices of .80 and 1, respectively. The inter-rater reliability of the milk ejection assessment form was tested in 10 mothers after cesarean section yielding a value of .80. The data were analyzed using percentage, mean, and standard deviation. The hypotheses were tested using one-way repeated measures ANOVA, pairwise comparisons with Bonferroni correction, and independent t-test statistics. The results showed that the mothers after cesarean section who received the lactation-promotion program combined with listening to music had mean scores of milk ejection after intervention at 24, 48, and 72 hours significantly higher than the control group (F = 504.08, p < .001) and the mean score of lactation time was significantly shorter than the control group for 14 hours (p < .001). The results demonstrated that the lactation-promotion program combined with listening to music could promote milk ejection and help shorten lactation time. Thus nurses should apply this program to promote and support successful breastfeeding in mothers after cesarean section
