Effect of PIONER (Oxytocin Massage with Electromagnetic Stimulation) on Breast Milk Production: A Repeated-Measures Intervention Study Among Postpartum Mothers
Introduction: Breast milk production is regulated by prolactin and oxytocin, and oxytocin massage is known to facilitate milk ejection. To address limitations of manual stimulation, an electromagnetic-assisted oxytocin massage device (PIONER) was developed to support postpartum mothers in improving breast milk flow. This study aimed to evaluate the effectiveness of the PIONER device in improving breast milk production indicators among postpartum breastfeeding mothers. Methods: A quasi-experimental repeated-measures design was conducted involving 10 postpartum breastfeeding mothers selected using purposive sampling from three community health centers in Ternate City. PIONER-assisted oxytocin massage was administered on days 1, 3, 5, 7, and 9, twice daily for 10 minutes. Breast milk adequacy indicators urination frequency, defecation frequency, breastfeeding frequency, infant sleep duration, and infant weight were measured on days 2, 4, 6, 8, and 10. Data were analyzed using repeated-measures ANOVA (Greenhouse–Geisser correction) with a significance level of ? = 0.05. Results: Significant time-based differences were observed for urination frequency (F = 13.500, p = 0.005), defecation frequency (F = 25.839, p < 0.001), and infant weight (F = 45.375, p < 0.001). No significant changes occurred in breastfeeding frequency or sleep duration. Confidence intervals could not be calculated because raw standard errors were not available. Conclusion: PIONER effectively improved indicators of breast milk production, particularly urinary and fecal output and infant weight gain, with no adverse effects observed during the study. Larger controlled studies are recommended to strengthen generalizability.

Background: Optimal breast milk production meets infants’ nutritional needs, crucial in stunting prevention. Many postpartum mothers face insufficient milk production, which can affect infant weight gain and increase the risk of stunting. The innovation of combining oxytocin massage with Foxy Oil is expected to enhance breast milk volume, frequency of wet diapers, and infant weight gain—key indicators in stunting prevention. Methods: This study used a quasi-experimental design with purposive sampling, involving 60 postpartum mothers: 30 in the intervention group and 30 in the control group. Statistical analyses were conducted using SPSS 26 for univariate and bivariate data. Data normality was tested using the Kolmogorov-Smirnov test and bivariate analysis with the Mann-Whitney test. Breastfeeding optimisation was assessed based on breast milk volume, number of wet diapers, and infant weight over one month in the working area of Tanjung Morawa Community Health Centre. The husband or a close family member performed an Oxytocin massage twice daily for 10–15 minutes. Results: Bivariate analysis after oxytocin massage showed significant effects on breast milk volume (p = 0.000), number of wet diapers (p = 0.000), and infant weight (p = 0.039). The analysis indicates that the combination of Foxy Oil and oxytocin massage positively affects breast milk production, frequency of wet diapers, and infant weight gain. Conclusion: Foxy Oil's innovation, combined with oxytocin massage, can be widely applied in midwifery practice to support successful exclusive breastfeeding and contribute to stunting prevention.

Postpartum is closely related to the lactation process. The lactation process is the entire process of breastfeeding, starting from the milk produced, secreted, and expenditure of breast milk, this process also continues until the process of breastfeeding babies. Yet, in the first days after childbirth mothers experienced anxiety and fear of a lack of milk production, this causes a decrease in the hormone oxytocin which inhibits the let down reflex; therefore breast milk cannot be produced after giving birth. Therefore, it is necessary to stimulate the oxytocin reflex before expressing milk. One method of stimulation that can be done on the mother is by giving an oxytocin massage. An oxytocin massage is a massage performed on the cervical spine, back, or along the spine up to the fifth to sixth bone. The purpose of this research is to analyze the effectiveness of oxytocin massage in increasing breast milk production in postpartum mothers. This research used a quasi-experimental method with a pretest-posttest design with a control group. A consecutive technique was used. Data analysis used a paired t-test, Wilcoxon test, and Mann-Whitney test. The results show that there are differences in breast milk production in postpartum mothers assessed based on the baby's urine after receiving oxytocin massage with a value of p = 0.000 and without oxytocin massage with a value of p = 0.009. There is a difference in breastfeeding breast milk production assessed based on infant weight after oxytocin massage with p = 0.000 and without oxytocin massage with a value of p = 0.000. There is effectiveness of oxytocin massage in increasing breast milk production assessed based on the baby's urine with a value of p = 0.021 and infant weight with a p value = 0.042. The conclusion is that oxytocin massage is effective in increasing breast milk production in postpartum mothers at the Independent Practice Midwife Hermayanti East Pontianak.

The postpartum period refers to the first 42 days after childbirth. Breast milk contains the most appropriate and complete nutrient. Besides, it always adapts to the needs of the baby. There are several benefits of breast milk for babies the number of calories in breast milk can meet the needs of the baby, breast milk contains protective substances, and it strengthens the bond between a mother and her baby. Breast care stimulates prolactin, the hormone which helps milk production to facilitate breast milk. Oxytocin massage stimulates the posterior pituitary to release oxytocin, thus breast milk production is increased. This research aimed to determine the effect of breast care and oxytocin massage on breast milk production of postpartum mothers. In this research, the pre-experimental method was employed with a two-group pretest-posttest design. Most of the research respondents were 20-35 years old, multiparas, and graduated from junior and senior high school. Before breast care and oxytocin massage were conducted to 27 (93%) and 24 (86%) postpartum mothers respectively, most of them had low breastmilk supply. While, after the treatments were given to 27 (93%) postpartum mothers with breast care, and 24 (86%) postpartum mothers with oxytocin massage, most of the respondents had better milk production. The Mann Whitney test held after breast care and oxytocin massage indicated that p-value was 0.000 (p<0,05) for both variables. There is an effect of breast care and oxytocin massage on breast milk production of postpartum mothers.

Postpartum blues is a mild adaptation disorder in postpartum mothers that affects psychological and physiological conditions, including breast milk production. This condition significantly impacts maternal health and infant development. This study aimed to examine the association between oxytocin massage, oxytocin hormone levels, and breast milk production in mothers with postpartum blues. A quasi-experimental pre-test and post-test design with treatment and control groups was used. The study was conducted at Siti Fatimah Special District Hospital for Maternal and Child Makassar and Pertiwi Mother and Child Hospital Makassar, from February to November 2024. A total of 68 postpartum mothers with postpartum blues were divided into two groups (34 participants per group). Screening was performed using the EPDS scale, oxytocin levels were measured using the ELISA method, and Breast milk production was assessed using a composite scoring system based on three main indicators: (1) infant weight gain, evaluated using the mean value (X̄) and standard deviation (SD); (2) breastfeeding frequency, recorded through maternal reports and structured observation; and (3) breastfeeding duration, assessed based on the average time per feeding session. Each indicator was assigned a score ranging from 1 to 3, corresponding to low (score 1), moderate (score 2), and high (score 3) levels. The total score from these three components was used to classify overall breast milk production into three categories: high production (total score 7-8), moderate production (total score 5-6), and low production (total score 3-4). Statistical analysis was conducted using SPSS. The baseline characteristics were evenly distributed across between the groups. The reduction in EPDS scores was greater in the treatment group (13.44 ± 2.765 to 12.12 ± 3.832) than in the control group (13.97 ± 3.196 to 13.26 ± 2.864), with a significant between-group difference (p = 0.000). Moreover, oxytocin levels increased significantly in the treatment group (47.57 ± 10.42 pg/mL to 52.62 ± 11.33, p = 0.001), whereas no significant change was observed in the control group, except for the comparison of the difference in oxytocin levels between the two groups confirming that this difference is statistically significant (p = 0.007). This study suggests that oxytocin massage may serve as a complementary approach therapy for reducing postpartum blues symptoms and enhancing breast milk production. Its integration into clinical practice can support maternal postpartum care by promoting emotional well-being and improving lactation outcomes.

Oxytocin massage, a technique involving the massaging of the vertebrae to the fifth-sixth costae (ribs), aims to stimulate the hormones prolactin and oxytocin, thereby enhancing breast milk production. Breast milk is the optimal nourishment for infants, containing the essential nutrients in ideal proportions. A common challenge in the initial stages of breastfeeding is the insufficient production of breast milk on the first day postpartum. Oxytocin massage is a method used to facilitate the smooth flow of breast milk. This study aims to increase the knowledge of postpartum mothers about oxytocin massage and its role in stimulating breast milk production. A descriptive case study approach was employed in nursing practice. The study focused on educating postpartum mothers about the steps and benefits of oxytocin massage. The findings indicate that mothers who were educated about oxytocin massage not only understood the technique but were also able to perform it effectively. There was a notable increase in the mothers' knowledge and practical ability regarding oxytocin massage therapy. Enhancing the understanding and application of oxytocin massage among postpartum mothers can play a significant role in overcoming initial breastfeeding challenges, ensuring better nourishment for infants through increased breast milk production.

Background : The prevalence of exclusive breast feeding was 39.05% in Sukoharjo in 2015, which is far bellow the national target of 80%. A study has shown that massage oxytocin increases oxytocin (OT) hormone release, and eventually decreases adrenocorticotropin hormone (ACTH), nitric oxide (NO), and beta-endorphin (BE). This OT hormone release will increase milk ejection, which facilitate milk production. This study aimed to investigate the effect of breast care and oxytocin massages on breast milk production in post–partum mothers. Subjects and method: This was a Randomized Controlled Trial (RCT), conducted at Sukoharjo Hospital, Central Java 19 October to November 18, 2016. A total of 90 post – partum mothers were selected at random and then allocated into breast care group and oxytocin massage group. The dependent variable was breast milk production. The independent variable was breast care and oxytocin massage. Changes in breast milk production before and after intervention between the two groups were tested by Mann-Whitney test. Results: The increase in breast milk production in breast care and oxytocin massage group (mean = 17.37, SD = 9.70) was larger than that of the control group (mean = 1.58, SD = 1.69), and it was statistically significant (p <0.001). Conclusion: Breast care and oxytocin massage can significantly increase breast milk production. Post-partum mothers are recommended to practice breast care and oxytocin massage, in order to increase breast milk production. Keywords: breast care, oxytocin massage, breast milk production.

Background: The incidence of post-partum blues both in Indonesia and abroad has been quite high; the stress that post-partum mothers experience will inhibit breast milk production and, as a result, breastfeeding process should be stopped earlier. Hypnobreastfeeding relaxation and oxytocin massage have been a combination of therapy that might decrease the rate of Adenocorticotropic Hormon (ACTH) and that might assist hormone and prolactin secrection in order that breast milk production becomes fluent. This study then aimed at analyzing the optimization of the combination of oxytocin massage and hypnobreastfeeding in order to decrease anxiety and to improve breast milk production among post-partum mothers. Subjects and Method : This was an analytic experimental study with Randomized Control Trial (RCT) design. This study was conducted at Dr. Suradji Tirtonegoro Central General Hospital, Klaten, from January 25 th , 2017 until March 9 th , 2017. The population in this study was 200 post-partum mothers. A sample of 60 post-partum mothers was selected for this study and allocated into the intervention group (n1= 30) and the control group (n2= 30). The intervention group would be treated by the combination of oxytocin massage and hypnobreastfeeding. The dependent variables were anxiety and breast milk production. The independent variables were oxytocin massage and hypnobreastfeeding. The anxiety was measured by STAI scale. The breast milk production process was measured by checklist questionnaire. The breast milk production amount was measured by milking cups. The breast milk production between the two groups was tested by Mann-Whitney. Results : The anxiety scale in the intervention group was better and lower than that of the control group. The differences in terms of anxiety scale between the intervention group (median= 24.00; SD= 4.45) and the control group (median= 34.00; SD= 6.93) were statistically significant (p<0.001). Then, the differences in terms of breast milk production process between the intervention group (median= 9.00; SD= 1.66) and the control group (median= 8.00; SD= 1.56) were nearly significant (p<0.145). Furthermore, the differences in terms of breast milk production amount between the intervention group (median= 10.00; SD= 10.36) and the control group (median= 4.50; SD= 4.21) were statistically significant (p<0.001). Conclusion: Combination of oxytocin massage and hypnobreastfeeding can effectively decreasing anxiety and increasing breast milk production for post-partum mothers.
