Injuries Resulted From Breastfeeding: A New Approach To A Known Problem

Effectiveness of photobiomodulation therapy on pain intensity in postpartum women with nipple or perineal trauma: protocol for a multicentre, double-blinded, parallel-group, randomised controlled trial

INTRODUCTION

Photobiomodulation (PBM) using low-level laser can affect tissue repair mechanisms and seems promising in reducing pain intensity. However, few studies support the effectiveness of PBM on postpartum period complications, such as nipple and/or perineal trauma and pain, probably due to the low doses used. The primary objective of this study is to analyse the effectiveness of PBM on pain intensity in the nipple and perineal trauma in women in the immediate postpartum period. Secondary objectives are to evaluate the effect on tissue healing and the women's satisfaction.

METHODS AND ANALYSIS

A double-blind, multicentre, parallel-group, randomised controlled trial will be performed in two public referral maternity hospitals in Brazil with 120 participants, divided into two arms: 60 participants in the nipple trauma arm and 60 participants in the perineal trauma arm. Participants will be women in the immediate postpartum period, who present with nipple trauma or perineal trauma and report pain intensity greater than or equal to 4 points on the Numerical Rating Scale for Pain. Block randomisation will be performed, followed by blinding allocation. In the experimental group, one application of PBM will be performed between 6 hours and 36 hours after birth. For the sham group, the simulation will be carried out without triggering energy. Both participants and the research evaluator will be blinded to the allocation group. Intention-to-treat method and the between-group and within-group outcome measures analysis will be performed.

ETHICS AND DISSEMINATION

This research protocol was approved by the Research Ethics Committees of the University of Campinas, Brazil, and of the School Maternity Assis Chateaubriand, Brazil (numbers CAAE: 59400922.1.1001.5404; 59400922.1.3001.5050). Participants will be required to sign the informed consent form to participate. Results will be disseminated to the health science community.

Initial nipple damages in breastfeeding women: analysis of photographic images and clinical associations

OBJECTIVE

to analyze the initial nipple damage degree by breastfeeding practice and to associate findings with clinical manifestations of breastfeeding women.

METHODS

a retrospective, cross-sectional study with primary data and photographic images database from two randomized clinical trials. Photographic images were analyzed by two independent evaluators using the Nipple Trauma Score. For analysis, the chi-square, Mann-Whitney tests and Kappa coefficient were applied.

RESULTS

115 breastfeeding women and their respective 186 photographic images were analyzed. The degree of agreement of evaluators using the Nipple Trauma Score was 93.6%. The nipple pain score during breastfeeding was moderate and compromised more than 25% of the nipple surface area.

CONCLUSIONS

assistance to breastfeeding women should prioritize nipple pain intensity instead of the nipple damage size.

Construction and validation of an instrument for classifying nipple and areola complex lesions resulting from breastfeeding

OBJECTIVES

to construct and validate a classification of nipple and areola complex lesions resulting from breastfeeding, according to content and appearance.

METHODS

this is a methodological study, developed in four stages: operational definition, instrument construction, content and appearance validation. The Delphi technique and a Likert-type scale were used to validate content and appearance, through the participation of ten and sixteen judges, respectively. For analysis, Content Validity Index and Kappa Coefficient were applied.

RESULTS

Content Validity Index obtained an overall value of 0.93 and, for appearance, 0.94. Kappa values ranged between 0.46 and 1. The high rates of agreement among judges demonstrated the quality of the proposed content validity.

CONCLUSIONS

the Nipple and Areola Complex Lesions Classification Instrument developed obtained acceptable values of its indexes, proving to be valid in terms of content and appearance.

Effectiveness of photobiomodulation therapy for nipple pain or nipple trauma in lactating women: a systematic review protocol

OBJECTIVE

The objective of this protocol is to evaluate the effectiveness of photobiomodulation therapy for the treatment of nipple pain or nipple trauma in women during the breastfeeding period.

INTRODUCTION

One approach that has been reported on the management of nipple pain or nipple trauma in lactating women is the use photobiomodulation therapy to heal the injury or to decrease pain intensity. However, studies have achieved different results, due to variations in the treatment protocol, such as the source of light used, the application mode, the irradiation, or the light dose parameters, leading to varying outcomes.

INCLUSION CRITERIA

This review will consider studies that evaluate photobiomodulation therapy for the treatment of nipple pain or nipple trauma in lactating women in the postpartum period that compare the intervention to standard care, placebo, or other type of treatment. The following outcomes will be considered: intensity of nipple pain, healing of nipple trauma, exclusive breastfeeding rate, quality of life, and satisfaction of the women with treatment. There will be no publication time limit, and studies published in any language will be considered for inclusion.

METHODS

This review will be conducted in accordance with JBI methodology for systematic reviews of effectiveness. The search strategy will search both published and unpublished studies, and the process of study selection, critical appraisal, data extraction, and data synthesis will be performed in accordance to the JBI approach.

A retrospective analysis of debridement in the treatment of chronic injury of lactating nipples

Treatment strategies for nipple injury are mainly based on aetiology. However, some damaged nipples do not heal after the aetiology was corrected. This study retrospectively analyses the effect of debridement for treating chronic injury of lactating nipples. The medical records on nipple injury management in the authors’ department from December 2015 to January 2020 were retrospectively analysed. A total of 167 patients were enrolled and grouped based on the presence or absence of nipple debridement. The difference in the healing effect, pain relief rate and recurrence rate of nipple injury between the two groups after 1 week was examined. The cure rate of nipple injury in the intervention group (54.3%) was significantly higher than in the control group (26.7%). In addition, the complete pain relief rate in the intervention group (48.1%) was significantly higher than in the control group (23.3%). However, the recurrence rates between the two groups (36.4% (16/44) vs. 34.8% (8/23)) had no statistically significant differences. For patients with no improvement after correction of the aetiology of the in the nipple damage, debridement can improve the healing environment of nipple breakage and thus relieve nipple pain.

Lanolin and prenatal health education for prevention of nipple pain and trauma: Randomized clinical trial

OBJECTIVE

To investigate the effect of lanolin on nipple pain and trauma in breastfeeding after application of a health education.

METHOD

Randomized controlled clinical trial, with two arms, open, with 66 participants during prenatal care in the primary health care network in Goiania - Goias, Brazil. Participants were randomized (1:1) using computer generated numbers in both experimental group (EG) and control group (CG). The EG received lanolin and health education on breastfeeding at two different times with clinical demonstration using cloth didactic breast and illustrative album as the intervention, while the CG received standard health education. Health education was carried out by the same researchers in both groups. Measurement of pain, nipple trauma, and breastfeeding technique occurred on postpartum day eight. The analysis included descriptive statistics and inferential analysis by means chi-square or Fisher test, and Student's t-test, significance level set at 0.05.

RESULTS

A majority of the participants experienced no nipple trauma (59.1%) in both groups, and 60.6% of women experienced pain. In both groups, women showed favorable breastfeeding behaviors, except in the condition of the breasts. There were no significant differences between groups in pain prevention (p=0.61), nipple lesions (p=0.21), and breastfeeding technique (p>0.05).

CONCLUSION

It is not clear whether the intervention, lanolin combined with health education, has a positive effect on the prevention of nipple pain and trauma. Further research is needed to elucidate this question. Registration number: RBR-7tvhq8. Registry website: http://www.ensaiosclinicos.gov.br/.

Prevalence of nipple traumas and related factors among post-partum women assisted in a teaching hospital

Abstract Objectives: To estimate the prevalence of nipple traumas and to correlate this occurrence with socio-demographic and obstetric factors in a sample of assisted post-partum patients in a teaching hospital. Method: Cross-sectional, quantitative study of 320 post-partum patients assisted in the maternity from October 2015 to October 2016. Results: The prevalence of nipple trauma in the sample was 35.3%, and only previous experience with breastfeeding has behaved as a protective factor for trauma. No statistical associations were found with other variables. Conclusions and implications for practice: The data presented allowed us to delineate a profile of the post-partum patients assisted in a teaching hospital, as well as the characterization of the occurrence of nipple traumas. From this profile, guidelines can be established on the subject, both in the institution where the study was carried out and in other institutions, since from the literature, the need for this orientation in different contexts and institutions is identified.

Nipple Skin Trauma in Breastfeeding Women During Postpartum Week One

OBJECTIVE

To objectively describe changes to nipple skin and classify signs of nipple trauma in breastfeeding women during postpartum week 1.

METHODS

This study was conducted in two phases. Phase 1 was an observational prospective study of breastfeeding mothers in which data were obtained from photographs and digital images of nipple skin and analyzed to anatomically classify signs of nipple trauma. In Phase 2, the reliability of signs identified in Phase 1 was verified with the cooperation of eight clinical midwives.

RESULTS

A total of 776 images of 50 breastfeeding mothers were obtained daily. The signs of nipple trauma included erythema, swelling, blistering, fissure, and scabbing. Purpura and peeling were identified only with photographic image analysis. Scabbing and blistering were classified as damage to the dermis, and erythema and swelling as damage to the epidermis, based on anatomical evidence and the mothers' subjective experiences of pain intensity. Erythema and swelling were observed from day 0, with erythema most frequently observed. For inter-rater reliability of the five signs of nipple trauma, Kendall's coefficient of concordance ranged from 0.46 (moderate) to 0.85 (almost perfect). Reliability was high for fissure, substantial for blistering and scabbing, and moderate for erythema and swelling.

CONCLUSIONS

Image analysis revealed five signs of nipple trauma. Erythema and swelling were the most frequently observed signs during postpartum week 1. However, the agreement rate was lower than that for other signs, suggesting the possibility of conflicting interpretations in clinical evaluation.

Dificuldades relacionadas ao aleitamento materno: análise de um serviço especializado em amamentação

Resumo Objetivo Analisar a associação entre o tipo de aleitamento e as dificuldades relacionadas à essa prática entre mulheres e crianças assistidas em um ambulatório especializado em amamentação. Métodos Estudo transversal retrospectivo realizado por meio da análise de prontuários de crianças e mulheres atendidas entre 2004 e 2016 em um ambulatório especializado em aleitamento materno. Foram excluídos os registros referentes às mulheres com gestação múltipla e àqueles não realizados em formulário padrão, totalizando 1.608 prontuários. Utilizaram-se os testes Qui-Quadrado e Kruskal-Wallis para comparar o tipo de aleitamento materno com variáveis categóricas; e com os dias de vida e idade materna, respectivamente. O teste Mann-Whitney utilizou-se para comparar a frequência do aleitamento materno exclusivo. Resultados O aleitamento materno exclusivo foi praticado por 72,6% das mulheres atendidas, nos primeiros 30 dias após o parto. Houve associação significativa entre esta prática e as dificuldades: percepção materna quanto à quantidade de leite produzida, de mamas cheias antes das mamadas, de vazamento de leite e extração manual do leite com facilidade; posicionamento materno e da criança, preensão, sucção e deglutição da criança adequados; além das variáveis: maior escolaridade, situação conjugal estável; ter tido experiência prévia com aleitamento materno, ter mamilos protrusos, ter realizado contato precoce pele a pele, ter filhos com menor média de dias de idade e que faziam uso de chupeta. Conclusão O aleitamento materno exclusivo foi o mais prevalente nos primeiros 30 dias pós-parto e diversas variáveis maternas e neonatais estiveram associadas à essa prática no primeiro atendimento em ambulatório especializado.

CONJUNTO DE MEDIDAS PARA O INCENTIVO DO ALEITAMENTO MATERNO EXCLUSIVO INTRA-HOSPITALAR: EVIDÊNCIAS DE REVISÕES SISTEMÁTICAS

Objective:

To identify the main recommendations found in systematic reviews regarding exclusive breastfeeding protective factors.

Data source:

Integrative review based on the guiding question: What evidence is found in literature regarding the protective factors of exclusive breastfeeding during the intrahospital period? A search was conducted in the Cochrane Library, PubMed/MEDLINE and LILACS database using the keyword “Breast Feeding” and the word “Breastfeeding”. Systematic reviews published from 2007 to 2016 that answered the guiding question were included in the study, whereas systematic reviews that analyzed breastfeeding of preterm infants and breastfeeding of children with orofacial malformation were excluded. The sample included eight systematic reviews.

Data synthesis:

The recommendations related to the protective factors for exclusive in-hospital breastfeeding found in the systematic reviews were: early skin-to-skin contact, rooming-in care, intervention for treating painful nipples during breastfeeding, restriction of infant supplementation, baby-led breastfeeding and educational interventions and support for mothers during hospital stay. The proposed measures included the six practices presented as protective factors.

Conclusions:

The review enabled the identification of evidence to support the recommended measures from delivery room to hospital discharge, with the aim of encouraging breastfeeding and preventing intrahospital weaning,

Factors associated to nipple trauma in lactation period: a systematic review

Abstract Objectives: To identify the characteristics associated to nipple trauma in nursing mothers and propose a theoretical model explaining in hierarchical levels its determining factors. Methods: a systematic review of the literature based on the search of epidemiological studies of factors associated to nipple trauma in the databases of Medical Literature Analysis and Retrieval System Online/Pubmed, Literatura Latino-Americana and Caribe em Ciências da Saúde (Latin American Literature and Caribbean Health Sciences) and ScienceDirect. The conduct on searching articles occurred until June 2016. Results: 17 articles were selected which investigated 27 variables and found a significant association between 16 of these variables and nipple trauma. The factors associated to nipple trauma reported in two or more studies were: mother of race/color white or yellow, primiparity, inadequate position between mother and child during breastfeeding and handling the infant incorrectly to the mother's breast. Guidance received on handling and positioning the infant during prenatal care was a protective factor against nipple trauma. Conclusions: in the theoretical model explaining the factors associated to nipple trauma in hierarchical levels, the variables classified at the proximal level were the most investigated and were identified as risk factors in selected studies, indicating that in the postpartum care period is an important protective factor against nipple trauma.

Factors Associated with Nipple Lesions in Puerperae

This retrospective cross-sectional study aimed to evaluate the factors associated with nipple lesion development in puerperae. Analyses were performed using the Poisson regression with robust variance. The level of significance was set at 5% (p < 0.05). We evaluated 1270 puerperae, among whom 193 (15.4%) presented with nipple lesions. The condition was more prevalent among the mothers who did not receive information about breastfeeding [PR, 1.69; 95% confidence interval (CI), 1.19-2.42], those who underwent cesarean delivery (PR, 1.48; 95% CI, 1.02-2.16), those who used a pacifier (prevalence ratios (PR), 2.04; 95% CI, 1.05-3.95), those who used baby formula only (PR, 1.61; 95% CI, 4.82-5.36) and those who used baby formula combined with breastfeeding (PR, 1.61; 95% CI, 1.06-2.45). A lower incidence of nipple lesions was observed among those who did not receive information on hand expression of breast milk (PR, 0.65; 95% CI, 0.46-0.93) and those who did not breastfeed in the first hour of life (PR, 0.61; 95% CI, 0.38-0.97).
