Abstract
BACKGROUND: The success of a woman in following the exclusive breastfeeding program is determined by the significant effort of a woman in giving breast milk and providing additional food to the baby. This problem can be solved by using the vibration effect on the postpartum mother's breast through DC Motor Vibratory (DMV) system. AIM: Therefore, the research aims to analyse the effectiveness of DMV among postpartum woman on giving breast milk. This intervention will assist to stimulate the prolactin hormone and to remove the oxytocin hormone of the breast milk. METHODS: The study is a quasi-experiment, with only post-test design and control group. The sample of the study included 76 postpartum women in University of Sumatera Utara (USU) Hospital and maternity clinic in Medan, Indonesia with accidental sampling technique. The data were collected by using questionnaires, such as demographic questionnaire and observation of breast milk expenditure. The study was analysed by using the Mann-Whitney test. RESULTS: The Result of the study showed that the DMV could accelerate the process of breastfeeding for a postpartum woman with a significant value of p < 0.05. CONCLUSION: The research concluded that DMV could be applied in the postnatal care process, especially in stimulating breast milk expenditure.
