Abstract
Importance
Breast milk is the safest food for infants and has many psychological and physical benefits for infants and mothers. However, problems encountered during the breastfeeding process can reduce postpartum women's willingness to breastfeed. Lactation and engorgement may be improved through Traditional Chinese Medicine auxiliary therapy. However, the overall efficacy of various Traditional Chinese Medicine auxiliary therapies and the relevant meridians and acupuncture points for treating breast milk deficiency remain unclear.
Objective
To investigate Traditional Chinese Medicine auxiliary therapy's effectiveness and acupoints for postpartum women who experience problems during the breastfeeding process.
Methods
Data were sourced from Embase, Web of Science, CINAHL, Cochrane, CNKI, PubMed, and the Airiti Library Central Register of Controlled Trials and Clinical Trials from the database inception to October 2022. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.
Main outcome measures
The primary outcomes were overall efficiency, prolactin level, milk volume, and breast engorgement in postpartum women with lactation deficiency after-assisted therapies and the correlation between meridian points and milk secretion.
Results
A total of 1,516 studies were initially identified, and 357 articles were assessed. In the final analysis, 20 studies were included, covering various Traditional Chinese Medicine therapies (acupuncture, acupressure, scrapping, moxibustion cupping, etc.) to stimulate relative acupoints without any acupoint stimulation. The overall efficiency (odds ratio [OR] = 14.17, 95% confidence interval [CI] = 6.49 to 30.92), prolactin level (standardized mean difference [SMD] = 0.36, 95% CI = 0.074 to 0.64), improvement of milk volume (SMD = 0.94, 95% CI = 0.59 to 1.29), reduction of engorgement level (OR= 18, 95% CI = 8.34 to 38.82) demonstrated that Traditional Chinese Medicine therapies can effectively improve lactation and breast fullness, thereby helping patients with breast milk deficiency. The most common acupuncture points used to treat agalactia were classified as the Stomach Meridian, Small Intestine Meridian, and Conception Vessel, with the common acupoints CV17: Danzhong, ST18: Rugen, SI1: Shaoze, ST36: Zusanli, and ST16: Yingchuang.
Conclusion
Adjuvant Traditional Chinese Medicine therapy can improve lactation and breast engorgement, thereby increasing the willingness to breastfeed. Clinical Finding: 1. The best time for Traditional Chinese Medicine acupoint intervention for breast deficiency treatment is within 24 h 2. The most effective acupuncture points for improving milk deficiency and bloating pain are ST18: Rugen, ST16: Yingchuang, ST36: Zusanli, SI1: Shaoze, CV17: Danzhong. 3. Traditional Chinese Medicine is non-invasive and effective techniques such as scraping, cupping, acupressure and ear peas. 4. Traditional Chinese Medicine can be combined with other different acupuncture points according to the different constitutions of post-partum women. Breast acupressure, ear acupuncture, scrapping, cupping, and moxibustion are noninvasive treatments that can effectively help patients during lactation, and their clinical practice should be considered and widely promoted.
