Common Complications of Breastfeeding and Lactation: An Overview for Clinicians

Physiology of Human Lactation and Strategies to Support Milk Supply for Breastfeeding

Despite advances across the globe in breastfeeding initiation rates, many families continue to report they are not meeting their breastfeeding goals. Concerns about milk supply, infant nutritional intake, and infant weight gain are among the most commonly cited reasons for early breastfeeding cessation. Nurses working with individuals during the perinatal period are uniquely positioned to educate families and offer evidence-based interventions to promote optimal milk supply, infant growth, and maternal mental and physical health. Such interventions include early and frequent skin-to-skin care, emptying of the breast, and professional lactation support. By implementing such evidence-based practices in the first hours after birth and connecting families to lactation support in the first 14 days, nurses can begin to help families achieve their breastfeeding goals.

"Health challenges and midwifery support for new mothers after childbirth: A cross-sectional study in Sweden"

OBJECTIVE

This study aimed to investigate new mothers' self-rated and perceived health problems and complications; their reasons for, and the frequency of, emergency department visits; how emergency department visits were associated with sociodemographic and obstetric factors; and new mothers' experiences of received support from the midwifery clinic.

DESIGN

A cross-sectional survey.

SETTING AND PARTICIPANTS

The study was conducted at 35 of 64 midwifery clinics in Stockholm, Sweden. The study population consisted of 580 new mothers.

MEASUREMENT AND FINDINGS

Descriptive statistics and logistic regression were used. New mothers experience a range of different health problems and complications during the first four weeks after giving birth. Sixteen percent sought emergency care. The odds of seeking emergency care increased for women with higher age and poorer self-rated health. Sixty-three percent of the new mothers received support from a midwife in primary care within the first four weeks after childbirth. Mothers who did not receive the support they wanted, expressed a wish for earlier contact and better accessibility.

CONCLUSION AND IMPLICATION FOR PRACTICE

It is notable that 16 % of new mothers seek emergency care in the first weeks after childbirth. This study has practical implications for midwifery practice and policy. There is a need for tailored postnatal support strategies so that midwives potentially are able to mitigate emergency department visits. Further studies should look at whether the high number of emergency visits among new mothers varies throughout Sweden, and whether this may be a result of reduced time of hospital stay after childbirth or other factors.

General practitioners' management of mastitis in breastfeeding women: a mixed method study in Australia

BACKGROUND

Mastitis is a common reason new mothers visit their general practitioner (GP). In Australia, the Therapeutic Guidelines: Antibiotic provides practical advice to GPs managing a range of infections, including mastitis. It is not known if Australian GPs prescribe antibiotics and order investigations as recommended for the management of mastitis.

METHODS

A convergent mixed methods design integrated quantitative analysis of a general practice dataset with analysis of interviews with GPs. Using the large-scale primary care dataset, MedicineInsight, (2021-2022), antibiotics prescribed and investigations ordered for mastitis encounters were extracted. Mastitis encounters were identified by searching 'Encounter reason', 'Test reason' and 'Prescription reason' free text field for the term 'mastitis'; 'granulomatous mastitis' was excluded. Clinical encounters for mastitis occurring within 14 days of a previous mastitis encounter were defined as belonging to the same treatment episode. Semi-structured interviews were conducted with 14 Australian GPs using Zoom or telephone in 2021-2022, and analysed thematically. The Pillar Integration Process was used to develop a joint display table; qualitative codes and themes were matched with the quantitative items to illustrate similarities/contrasts in findings.

RESULTS

During an encounter for mastitis, 3122 (91.7%) women received a prescription for an oral antibiotic; most commonly di/flucloxacillin ([59.4%]) or cefalexin (937 [27.5%]). Investigations recorded ultrasound in 303 (8.9%), blood tests (full blood examination [FBE]: 170 [5.0%]; C-reactive protein [CRP]: 71 [2.1%]; erythrocyte sedimentation rate [ESR]: 34 [1.0%]) and breast milk or nipple swab cultures in approximately 1% of encounters. Analysis using pillar integration showed consistency between quantitative and qualitative data regarding mastitis management. The following themes were identified: - GPs support continued breastfeeding. - Antibiotics are central to GPs' management. - Antibiotics are mostly prescribed according to Therapeutic Guidelines. - Analgesia is a gap in the Therapeutic Guidelines. - Low use of breast milk culture.

CONCLUSIONS

Prescribing antibiotics for mastitis remains central to Australian GPs' management of mastitis. Interview data clarified that GPs were aware that antibiotics might not be needed in all cases of mastitis and that delayed prescribing was not uncommon. Overall, GPs followed principles of antibiotic stewardship, however there is a need to train GPs about when to consider ordering investigations.

Breast hypoplasia markers among women who report insufficient milk production: A retrospective online survey

OBJECTIVES

To estimate the proportions of anatomical breast characteristics suggestive of breast hypoplasia among breastfeeding women self-reporting low milk supply. We also explored breast hypoplasia risk factors.

DESIGN

Online survey conducted between October 2021 and January 2022.

SETTING

Five low milk supply Facebook groups.

PARTICIPANTS

487 women reporting low milk supply with their first child born ≥ 37 weeks gestation within 5 years of participation in this study, and residing in the USA, Australia or the UK. We present data on the primary outcome ('breast type') for 399 women. Women were excluded if the dyad was separated for more than 24 hours during the hospital stay, or if the mother reported removing milk less than 6 times per day from each breast on most days before being aware of having insufficient milk production.

PRIMARY AND SECONDARY OUTCOME MEASURES

The proportions of proposed breast hypoplasia markers including atypical breast type, widely spaced breasts, breast asymmetry, stretch marks on the breast and lack of pregnancy breast growth. We also estimated the odds of having breast hypoplasia markers in at-risk groups compared to reference groups, adjusting for covariates.

RESULTS

Approximately 68% reported at least one atypical breast (270/399; 95% CI: 62.9%, 72.1%). Around 47% reported widely spaced breasts (212/449; 95% CI: 42.7%, 52.7%), 72% a lack of pregnancy breast growth (322/449; 95% CI: 68.3%, 77.4%), and 76% stretch marks on the breast (191/250; 95% CI: 70.7%, 81.3%). Multiple logistic regression analyses identified being overweight during pubertal years as a risk factor for atypical breast type and lack of pregnancy breast growth.

CONCLUSIONS

Participants in low milk supply Facebook groups reported high rates of breast hypoplasia markers. Being overweight during adolescence was a risk factor for breast hypoplasia markers. These findings should be confirmed in well-conducted large cohort studies to determine the strongest combination of hypoplasia markers in predicting low supply.

Evidence of the acupuncture points stimulation for the treatment of hypogalactia: A systematic review and meta-analysis

OBJECTIVE

To perform a literature review aimed to analyze if acupoint stimulation increases lactation quantity.

METHOD

Studies were collected from five electronic databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for systematic reviews. Eligibility criteria were full-text articles in English or Spanish with clinical trial design and observational studies, with no restriction on time of publication, in which the effect of acupoint stimulation on improving the quantity of lactation by conventional acupuncture, electroacupuncture, laser, fire needling, manual stimulation, tuina or catgut had been evaluated. Two authors independently extracted data for the characteristics and main outcomes of the studies selected for inclusion. The risk of bias (RoB 2 and Robins-I) and the quality assessments (GRADE) were performed. For the quantitative synthesis, the standardized mean difference was calculated for each individual study selected and then the data were combined using a random-effects meta-analysis.

RESULTS

A total of 14 studies were included in the present review. Most of the included studies exhibited some concerns in the risk of bias assessment. The quality of the studies was moderate. The meta-analysis showed that manual acupoint stimulation improves the lactation quantity (SMD 95% CI = 1.63 [1.13-2.13]; p < 0.0001).

CONCLUSION

The literature suggests that manual stimulation of acupuncture points improves the amount of milk produced during lactation.

The effectiveness of prenatal breastfeeding education on breastfeeding uptake postpartum: A systematic review

OBJECTIVE

The decision to breastfeed is influenced by physiological, psychological, and emotional factors. However, the importance of equipping mothers with the necessary knowledge for successful breastfeeding practice cannot be ruled out. Studies suggest that the decline in global breastfeeding rate can be linked to lack of adequate breastfeeding education during prenatal stage. Therefore, this review aims to determine the effectiveness of prenatal breastfeeding education on breastfeeding uptake postpartum.

METHOD

A systematic review of the studies identified by electronic database search (Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Psych INFO, and Sociological Abstracts and Applied Social Sciences Index and Abstracts (ASSIA) published between 2014 - 2021.

RESULTS

A total of 14 studies met the inclusion criteria. Results showed an increase in breastfeeding uptake, breastfeeding knowledge, increase in positive attitude to breastfeeding and an increase in maternal breastfeeding self-efficacy among mothers who participated in breastfeeding educational programs during prenatal care.

CONCLUSION

Prenatal breastfeeding education increases women's knowledge of breastfeeding. Mothers who are knowledgeable about breastfeeding and hold a positive approach towards breastfeeding have the tendency to initiate breastfeeding and continue for a lengthened period. Findings demonstrates a general correlation between prenatal breastfeeding education and increased breastfeeding uptake postpartum. The high level of positive breastfeeding outcome inherent in all the studies can be attributed to prenatal breastfeeding education.
