Treatments for breast engorgement during lactation

Effects of traditional Chinese medicine-assisted intervention on improving postpartum lactation: A systematic review and meta-analysis

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.

Preliminary study of the effect of low-intensity focused ultrasound on postpartum uterine involution and breast pain in puerperal women: a randomised controlled trial

To evaluate the safety and efficacy of low-intensity focused ultrasound (LIFU) therapy in facilitating fundus descent and relieving postpartum breast pain compared with sham treatment. A multicentre, randomised, sham-controlled, blinded trial was conducted. A cohort of 176 eligible participants, who had normal prenatal check-ups and met the inclusion and exclusion criteria, were recruited from three medical centres and subsequently randomized into either the LIFU or sham group. All participants received three treatment sessions, wherein LIFU signal was applied to the uterus and breast sites using coupling gel, with the absence of ultrasound signal output in the sham group. Fundal height measurement and breast pain score were performed after each treatment. The primary outcome, uterine involution, was presented by measuring the fundal height of the uterus. The visual analogue scale (VAS) score, as a secondary outcome, was used to assess breast pain and determine the correlation between breast pain and fundal height as the outcome simultaneously. All participants were randomly assigned to either the LIFU group (n = 88) or sham group (n = 88), with seven individuals not completing the treatment. Overall, a statistically significant difference was noted in the rate and index of fundus descent after each treatment. The rate and index of fundus descent showed greater significance following the second treatment (rate: 1.5 (1.0, 2.0) cm/d; index: 0.15 (0.1, 0.18), P < 0.001) and third treatment (rate: 1.67 (1.33, 2.0) cm/d; index: 0.26 (0.23, 0.3), P < 0.001) in the LIFU group. VAS scores, which were based on the continuous variables for the baseline, first, second, and third treatments in the LIFU group (2.0 (2.0, 3.0), 1.0 (0.0, 2.0), 0.0 (0.0, 1.0), and 0.0 (0.0, 0.0) points, respectively), and the sham group (2.0 (2.0, 2.0), 2.0 (1.0, 2.0), 2.0 (1.0, 3.0), and 3.0 (1.0, 3.0) points, respectively), showed a statistically significant difference between the two groups. Meanwhile, the discrepancies in VAS score classification variables between the two groups were statistically significant. After the third treatment, a notable correlation was observed between the VAS score decrease and fundus descent rate; the more the VAS score decreased, the faster was the fundal decline rate in the LIFU group. LIFU therapy is safe and effective, contributing to the acceleration of uterine involution and the relief of postpartum breast pain.Trial ID The study has registered in the Chinese Clinical Trial Registry (ChiCTR2100049586) at 05/08/2021.

The Effect of Alternating Application of Cold and Hot Compresses on Reduction of Breast Engorgement Among Lactating Mothers

BACKGROUND

Breast engorgement is a common issue that affects breastfeeding initiation and continuation. Engorgement can cause exhaustion, making it difficult to care for and feed the infant, and it can cause a mother to wean her baby before she intends to initiate breastfeeding. This study aimed to determine the effectiveness of the alternating application of cold and hot compresses in reducing breast engorgement among lactating mothers. Design, sample size and setting: A quasi-experimental study design is used to conduct this study. A purposeful sample of 100 lactating mothers was screened in the postnatal ward for the presence of breast engorgement. The 100 mothers with engorgement were divided into two equal groups of 50 mothers each - the first group (the intervention) and the second group (the control) - at the postnatal ward of King Abdulaziz Hospital-National Guard in Alahsa City. Sampling and tools: The data collection was conducted over five months, from January 2023 until May 2023. Data collection was done through a structured interview questionnaire sheet. The questionnaire was divided into six parts: socio-demographic data, obstetric and initial women assessment, the six-point engorgement scale (SPES), the visual analog scale (VAS), the LATCH breastfeeding charting scale, and the Infant Breastfeeding Assessment Tool (IBFAT).

RESULT

The present study found no statistically significant difference between the study intervention and control groups in breast engorgement, LATCH level, or overall level of breastfeeding assessment before the intervention. While, in terms of breast engorgement, pain level, attachment, and LATCH, the overall levels of infant breastfeeding assessment across study time had a statistically significant variance among the study and control groups after the intervention at p values=<0.001.

CONCLUSION AND RECOMMENDATIONS

The alternating application of cold and hot compresses can have a significant role in reducing breast engorgement among lactating mothers. Women should be encouraged to use hot compresses and cold gel packs as an alternative treatment to reduce engorgement and promote comfort. In addition, the study results can be utilized to aid Saudi Arabian nurses and midwives in understanding the advantages of applying a cold gel pack and a hot compress and to decrease levels of engorgement, improve latch, and relieve discomfort.

Physical therapy intervention for breast symptoms in lactating women: a randomized controlled trial

BACKGROUND

Therapeutic ultrasound, education, and massage are the most common physical therapy interventions provided to mothers with breast symptoms. However, there is insufficient evidence on the effectiveness of the combination of these interventions. This study aimed to explore the effects of the combination of therapeutic ultrasound, education, and massage on breast symptoms in lactating women.

METHODS

This study was a single-blind randomized controlled trial. Postpartum lactating women aged from 21 to 45 with breast symptoms were recruited and randomly allocated to one of three groups (ultrasound group, sham group, and usual care group). The severity of breast symptoms (pain, redness, lump, general malaise), breast engorgement, breast hardness, body temperature, breast temperature, and milk volume were assessed at baseline (T1), immediately post-intervention (T2), and at 3 months following baseline (T3).

RESULTS

A total of 37 participants were included in the study (ultrasound group n = 12; sham group n = 12; usual care n = 13). The severity of breast symptoms (i.e., pain, lump, and general malaise) as well as breast engorgement, were significantly improved in the ultrasound group at T2 when compared to T1, and these improvements were sustained at T3. The severity of breast engorgement was significantly lower in the ultrasound group when compared to the usual care group at T2. However, no statistically significant differences were found between the ultrasound and sham groups for all outcomes at any assessment time points.

CONCLUSIONS

Physical therapy interventions may be beneficial in relieving breast symptoms in lactating women. Larger randomized controlled trials are needed to confirm the findings of this study.

Therapeutic Ultrasound Alone and Associated with Lymphatic Drainage in Women with Breast Engorgement: A Clinical Trial

Introduction: Breast engorgement (BE) is a problem that affects many women, especially in the first days of breastfeeding, producing inflammatory symptoms. Nonpharmacological therapies are inexpensive, safe, and can produce symptom relief. Objective: This study aims to analyze the safety of therapeutic ultrasound regarding possible risks of overheating and the effects of its use alone and associated with lymphatic drainage (LD) in women. Material and Methods: Effectiveness is measured through thermography, visual analog scale, and six-point scale of BE. This is a nonrandomized clinical trial with a sample of 34 in the ultrasound group (G1), 28 in the ultrasound and LD group (G2), and 37 in the control group (G3). Results: The mean reduction for engorgement was 1.3 ± 0.8 to G1, 1.4 ± 1.0 to G2, and 1.2 ± 0.9 to G3 according to the six-point scale. The mean reduction for pain level was 3.6 ± 2.1 to G1, 4.0 ± 3.1 to G2, and 4.0 ± 2.2 to G3 according to the visual analogue scale. Conclusion: It was observed that all therapies were effective in reducing the level of engorgement, according to the six-point scale. However, combined ultrasound and LD therapy has been shown to be more effective in reducing the level of pain. Brazilian Registry of Clinical Trials (RBR-6btb6zz).

Does the Academy of Breastfeeding Medicine's Clinical Protocol #36 'The Mastitis Spectrum' promote overtreatment and risk worsened outcomes for breastfeeding families? Commentary

BACKGROUND

In 2022 the Academy of Breastfeeding Medicine (ABM) published Clinical Protocol #36: The Mastitis Spectrum, which aims to update clinical approaches to management of benign lactation-related breast inflammation. The protocol has been timely because of the exponential increase in knowledge about the human milk microbiome over the past decade. This Commentary aims to continue respectful debate amongst clinicians and researchers within the Academy of Breastfeeding Medicine and more broadly, confident that we share a fundamental commitment to promote breastfeeding and support the well-being of lactating women, their infants and their families.

ANALYSIS

Although Clinical Protocol #36 offers advances, it does not fulfil the principles of best practice implementation science for translation of evidence into clinical guidelines. Clinical Protocol #36 inaccurately represents studies; misrepresents theoretical models as proven aetiologies; does not consistently attribute sources; does not reliably apply the SORT taxonomy; and relies upon single case reports. As a result, various recommendations in Clinical Protocol #36 lack an evidence-base or credible underlying theoretical model. This includes recommendations to use 'lymphatic drainage' massage, therapeutic ultrasound, and oral lecithin. Similarly, based on a contestable theoretical model which is presented as fact, Clinical Protocol #36 makes the recommendation to either reduce frequency of milk removal or to maintain current frequency of milk removal during an episode of breast inflammation. Although Clinical Protocol #36 limits this advice to cases of 'hyperlactation', the diagnosis 'hyperlactation' itself is undefinable. As a result, this recommendation may put breastfeeding women who present with breast inflammation at risk of worsened inflammation and decreased breast milk production.

CONCLUSION

Clinical Protocol #36 offers some advances in the management of breast inflammation. However, Clinical Protocol #36 also exposes clinicians to two international trends in healthcare which undermine health system sustainability: overdiagnosis, including by over-definition, which increases risk of overtreatment; and antibiotic over-use, which worsens the crisis of global antimicrobial resistance. Clinical Protocol #36 also recommends unnecessary or ineffective interventions which may be accessed by affluent patients within advanced economies but are difficult to access for the global majority. The Academy of Breastfeeding Medicine may benefit from a review of processes for development of Clinical Protocols.

Cabergoline for Lactation Inhibition After Second-Trimester Abortion or Pregnancy Loss: A Randomized Controlled Trial

OBJECTIVE

To assess cabergoline's efficacy at decreasing breast symptoms after second-trimester abortion or pregnancy loss.

METHODS

This was a double-blinded, block-randomized superiority trial comparing cabergoline 1 mg once to placebo for preventing bothersome breast engorgement after second-trimester uterine evacuation. We enrolled pregnant people at 18-28 weeks of gestation who were English- or Spanish-speaking and without contraindication to the study drug. Participants completed a validated, piloted, electronic survey at baseline and at multiple timepoints through 2 weeks postprocedure to assess breast symptoms, side effects, and bother. Our primary outcome was any breast symptoms (a composite of engorgement, milk leakage, tenderness, and need for pain relief) on day 4; we planned to enroll 80 patients to show a 30% difference in breast symptoms (80% power, α=0.049). A subgroup of participants returned for serum prolactin levels.

RESULTS

After screening 150 patients from April 2021 to June 2022, we enrolled 73 participants. Baseline demographics were balanced between groups: median gestational age was 21 weeks (range 18-26 weeks), 56.2% of participants were nulliparous, 34.2% self-identified as Hispanic, and 37.0% had public insurance. At baseline, reported breast symptoms were similar between groups. Among 69 participants who returned surveys on day 4, significantly fewer participants receiving cabergoline reported any breast symptoms compared with placebo (27.8% vs 97.0%, P<.001) (primary outcome) and fewer reported significant bother (2.8% vs 33.3%, P=.001) (secondary outcome). These differences persisted through day 14. Reported incidence and severity of bother from side effects were similar between groups: most common were constipation, fatigue, and headache. Serum prolactin levels were similar at baseline. On day 4, mean serum prolactin level was 6.5 ng/mL (SD 2.2) for those who received cabergoline and 18.0 ng/mL (SD 5.9) for placebo (P=.049).

CONCLUSION

Cabergoline is an effective and well-tolerated strategy to prevent breast symptoms after second-trimester abortion or pregnancy loss.

Review article: Functional dyspepsia and pregnancy-Effects and management in a special population

BACKGROUND

Around 10% of Americans meet the Rome IV criteria for functional dyspepsia (FD), with a significantly higher rate in women. FD also has a higher prevalence in women below the age of 50, suggesting that women who are affected are likely to be of reproductive age. Unfortunately, there is a lack of research or evidence-based guidelines on managing FD in pregnancy.

AIMS AND METHODS

To address this issue, we aimed to perform a systematic review of the interactions between FD and pregnancy and managing pre-existing FD in the peripartum and post-partum phases using current lifestyle, pharmacological, non-pharmacological and alternative medicine interventions.

RESULTS

Due to the lack of Rome IV FD-specific data in pregnancy, we instead performed a narrative review on how existing FD interventions could be extrapolated to the pregnant population. Where possible we use the highest level of available evidence or official guidelines to answer these questions, which often involves synthesising treatment and safety evidence of these interventions in other diseases during pregnancy. Finally, we highlight current substantial knowledge gaps requiring further research for the safe management of a pregnant patient with pre-existing FD.

CONCLUSIONS

Overall, despite the paucity of knowledge of treating FD during pregnancy, providers can mitigate this uncertainty by planning ahead with the patient. Patients should ideally minimise treatment until after breastfeeding. However, interdisciplinary resources are available to ensure that minimal-risk interventions are maximised, while interventions with more risks, if necessary, are justifiable by both the patient and the care team. Future investigations should continue to elicit the mechanistic relationship between FD and pregnancy while cautiously expanding prospective research on promising and safe therapies in pregnant patients with pre-existing FD.

Initiating and Supporting Breastfeeding: Guidelines for Interventions during the Perinatal Period from the French National College of Midwives

Exclusive breastfeeding is recommended for children for the first 4 to 6 months of life, with complementary foods added thereafter. It is the most ecological way of protecting the child's and mother's health. Training of health professionals is required to avoid transmitting inconsistent information in 3 areas: 1) implementing these 3 predictors: safe skin-to-skin, first breastfeed, and rooming-in 24/7; 2) teaching and monitoring: i) early signs of waking and feeding rhythms, ii) positioning and latching, and iii) signs of effective transfer; and 3) referring women to specialized support services if difficulties arise (eg, inadequate milk production, pain, cracked nipples, engorgement). Breastfeeding should continue during mastitis or an abscess. Ultrasound-guided needle aspiration is beneficial in treating an abscess. Précis: Information is provided to enable health professionals to better support breastfeeding and help women with the most common difficulties, thus promoting breastfeeding initiation and duration.

Efficacy of Cabbage Leaf versus Cooling Gel Pad or Diclofenac Gel for Patients with Knee Osteoarthritis: A Randomized Open-Labeled Controlled Clinical Trial

Background

Osteoarthritis (OA) is one of the most common joint degeneration ailments adversely affecting the elderly population by impairing their physical movements and quality of life. This study aimed to establish the efficacy of cabbage leaf application in alleviating pain-related distress and positively improving OA conditions.

Materials and Methods

Patients with moderate to severe (grades 3-4) OA by the Kellgren and Lawrence grading system with a poor to good Oxford Knee Score were selected for enrollment in this clinical trial. The participants were divided into three intervention groups: the cooling gel pad group for 20 minutes duration once a day (n = 20), the diclofenac gel group for 4 times a day (n = 20) as the control group (total n = 40), and the cabbage leaf group for 1-hour duration once a day (n = 20) as the experimental group (total n = 20). All trial participants were trained to record their Numerical Rating Scale (NRS) pain score and Oxford Knee Score and were advised to undergo weekly follow-ups and assessment of the outcome at 4 weeks. Data were analyzed by the paired t-test and analysis of variance (ANOVA).

Results

The cabbage leaf group and cooling gel pad group showed a significant difference in both the Oxford Knee Score (p < 0.001 in both groups) and NRS score (p < 0.001 in both groups) before and after the intervention, by using the paired t-test. The three study procedures were found to be significantly different with respect to both the Oxford Knee Score (p=0.012) and NRS score (p < 0.001), by using ANOVA.

Conclusion

This study clinically demonstrated that cabbage leaf application and cooling gel pad application showed similar improvements in reducing OA symptoms in terms of the overall NRS score and Oxford Knee Score. Their therapeutic effectiveness was better than that of diclofenac gel.

Evaluation of a new lactation device 'Lactamo' designed to apply massage, heat or cold, and compression to the breast

BACKGROUND

Common approaches to manage breastfeeding problems such as pain, blocked ducts, and milk production issues include breast compression, breast massage, application of warmth or cold, medications, and breastmilk expression. Several devices are available to apply heat or cold to the breast, however, none promote breast compression and/or massage simultaneously. A new device 'Lactamo' has been developed to address this.

METHODS

This study was a pre-market evaluation of the Lactamo device. The aims were to determine user safety, and satisfaction of Lactamo. The study was conducted in an Australian tertiary maternity hospital in 2019-2020. Women who were less than 3 months post-partum and were currently breastfeeding participated in the study. We conducted structured telephone surveys at 1 and 4 weeks post supply of Lactamo. Questions included demographic information, feedback on safety, usage, and perceived benefits of Lactamo.

RESULTS

The cohort (n = 30) consisted of equal number of primiparous and multiparous women, 50% were born in Australia and the remainder from 11 other countries. A total of 41 telephone surveys were conducted with 27 women. Of these, 26 (96%) had used Lactamo, and the one that did not, felt she did not have a lactation concern to warrant using it. All women indicated that the device was safe to use and had no concerns, apart from one woman who experienced itching because of the device but continued to use it over clothing as she found it beneficial. Most women used it at room temperature or warmed. The frequency of use varied from once per week (17%) to daily (33%), and use was often prompted by a lactation concern such as engorgement, pain, blocked ducts, and low supply.

CONCLUSION

Lactamo was found to be safe, and a valuable aid for breastfeeding women. More research is needed to understand the efficacy of the device in treating breastfeeding problems such as pain, blocked ducts, and milk production issues.

The Effect of Oketani Breast Massage on Successful Breastfeeding, Mothers' Need for Breastfeeding Support, and Breastfeeding Self-Efficacy: an Experimental Study

BACKGROUND

The negative effects of cesarean section on breastfeeding are a major global concern.

PURPOSE

This study aimed to determine the effect of Oketani breast massage on the maternal need for support during breastfeeding, breastfeeding success, and breastfeeding self-efficacy.

SETTING

Three hospitals affiliated to Shahid Beheshti University of Medical Sciences in Tehran, Iran, from April to July 2019.

STUDY DESIGN

The participants in this experimental study were 113 pregnant women who were candidates for cesarean section. The mothers were selected using convenience sampling and randomly assigned. In addition to routine care, the mothers in the intervention group received Oketani breast massages twice. However, the mothers in the control group received routine care. The data were collected using the Infant Breastfeeding Assessment Tool (IBFAT), LATCH Assessment Score, and the Breastfeeding Self-Efficacy Scale (BSES). The data were analyzed with SPSS 20 software via the independent samples t test, the Mann-Whitney U test, and the chi-square test.

RESULTS

The results of the study suggested that the breastfeeding success rate, which was evaluated with IBFAT in both the first two breastfeeding stages and the last pre-discharge breastfeeding, was significantly higher for the mothers in the intervention group (p < .001). In addition, the mother's need for support, which was evaluated with LATCH in the first two breastfeeding stages (p = .044) and the last pre-discharge breastfeeding (p < .001) in the intervention group, was less. The total number of breastfeeding sessions from birth to discharge was higher in the intervention group (p = .002). Furthermore, the mothers in the intervention group breastfed their infants in a significantly shorter time interval (p = .002). Breastfeeding self-efficacy, according to the BSES, was significantly higher in the mothers of the intervention group (p < .001).

CONCLUSION

Oketani massage can be used as a care intervention by nurses to improve breastfeeding in mothers who undergo cesarean sections.
