Evaluación del valor de acidez Dornic de la leche humana según el tiempo de conservación en freezer y el lugar de extracción / Assessment of Dornic acidity in breast milk based on storage time in the freezer and place of expression

Introducción. El grado de acidez Dornic (AD), medida indirecta del grado de contaminación de la leche humana cruda (LHC), proporciona información sobre la calidad de esta. Recién extraída, el valor oscila entre 1,0° y 4,0° (óptimo). Descalifica el consumo si es >8,0 °D. Se evaluó la correlación de la AD de la LHC de donantes internas (DI) y externas (DE) según el tiempo de conservación hasta la pasteurización, y se determinó la prevalencia de AD ≤4 ºD. Población y método. Estudio retrospectivo analítico. Resultados. Sobre 13 203 muestras, la AD a partir del día 14 de conservación fue menor en las donantes internas, de 2,92; (IC95% 2,69-3,15) versus 4,01 (IC95%: 3,94-4,08); p <0,001] con mayor proporción de AD ≤4 ºD (88 % en DI versus 76 % en DE); OR: 2,30 (IC95%: 1,25-4,24); p = 0,003. Coeficiente de correlación para las DI: R 2 :0; p = 1). Conclusión. La AD a partir del día 14 fue menor en DI, presentando mayor prevalencia de AD ≤ 4ºD. No existió correlación entre el tiempo de conservación y la AD en las DI.

Introduction. The degree of Dornic acidity (DA) is an indirect measure of milk contamination and quality. In freshly expressed milk, DA ranges between 1.0 and 4.0 (optimal). If DA is > 8.0 °D, it should be discarded. The correlation between DA in raw breast milk from internal donors (ID) and external donors (ED) based on storage time until pasteurization was assessed. Population and method. Retrospective, analytical study. Results. In 13 203 samples, DA was lower in IDs as of 14 days of storage: 2.92 (95% CI: 2.69­3.15) versus 4.01 (95% CI: 3.94­4.08), with a higher proportion of DA ≤ 4 °D (88% in IDs versus 76% in EDs); odds ratio: 2.30 (95% CI: 1.25­4.24). Conclusion. DA as of 14 days of storage was lower in IDs, with a higher prevalence of DA ≤ 4 °D. No correlation was observed between storage time and DA in ID samples.

Development and present situation of breast milk bank / 国际儿科学杂志

Foreign Breast milk Banks have developed for more than 100 years in foreign countries.They have not only established the corresponding the Human Milk Banking Association of North America and the European Breast Milk banks Association accordingly,but also established a mature breast milk banks management guideline.However,the research on cognition and technology of breast milk bank in China is still in the stage of exploration and needs further development.The desire for breast milk donation and acceptance of d onor human milk in puerpera are limited.At present,as more and more attention were paid to breast milk feeding,the current situation cannot meet the needs of medical development.We need a formal management guideline to guide the development of breast milk bank.In this article,we introduce the concept and importance of breasffeeding,the necessity and feasibility of establishing breast milk banks,the development prospects of the breast milk bank,for reviewing a systematic thinking of the cognitive formation of breast milk bank,and other aspects to form a system review of the knowledge of breast milk bank.We aim to let puerpera have a better understanding of breast milk bank,eliminate the concerns about donating breast milk and increase the breast milk donation rate,thus the premature babies and newborns with diseases will benefit from the construction of the breast milk bank.

Perfil calórico e higienicossanitário do leite pasteurizado pelo banco de leite humano do estado do Acre / Caloric and hygienicosanitary profile of the milk pasteurized by the human milk bank of the state of Acre

Este estudo teve por objetivo analisar o perfil calórico e higienicossanitário do leite humano pasteurizado pelo Banco de Leite Humano da Maternidade Barbara Heliodora, localizado no município de Rio Branco-AC. Trata-se de uma pesquisa descritiva e transversal realizada a partir de dados secundários do registro dos exames de teor calórico avaliados pelo crematócrito, e titulação de acidez pelo método de Dornic do leite humano coletado e processado pelo banco de leite humano referente ao período de janeiro a dezembro de 2014. Foram analisadas 499 amostras de leite humano, totalizando 146,39 litros de leite coletados. Deste leite humano pasteurizado 15% foi classificado como hipocalórico, 52% normocalórico e 33% hipercalórico. De acordo com o estágio de lactação, o leite maduro foi o leite com maior quantidade de doações. Em relação à acidez Dornic, encontraram-se resultados dentro da média de titulação aceitável, sendo os maiores valores encontrados na faixa de 4,1 a 7,9% (n=252). As perdas de leite materno representaram 18,34 litros, sendo as principais causas o prazo de validade expirado, quantidade insuficiente para o processamento, sujidade, frasco quebrado e doadora sem cadastro. As doações de leite humano são essenciais para a garantia do leite destinado às crianças que dele necessitam. Assim, o presente estudo concluiu que o leite é normocalórico e está próprio para o consumo, com relação ao alto teor calórico e baixa titulação acidez. É importante o registro dessas informações para que se intensifiquem os estudos nessa área e medidas que busquem melhorar as boas práticas de manipulação.

This study aimed to analyze the caloric and hygienic conditions of the pasteurized breast milk in a Breast Milk Bank in the maternity hospital Barbara Heliodora, in Rio Branco, Ac. This is a descriptive cross-sectional analyzes of secondary data survey of calorie tests by crematocrit, and titratable acidity of the Dornic method of human milk collected and processed by the Breast Milk Bank from January to December 2014. It was analyzed 499 samples of pasteurized breast milk or 146,39 liters. Of those, 15% was hypocaloric, 52% normalcaloric and 33% hypercaloric. The mature milk was the type of milk in more quantity of donations. The Dornic acidity found was between 4,1 to 7,9% (n=252), considered acceptable. A total 18,34 liters of breast milk wasted. The breast milk donations are essential guaranty of milk, designated to the ones in need. Therefore, the present study conclude that the milk is normocaloric and is suitable for consumption. It's important to record those informations so that more studies are performed in this area, besides measures and proceedings of good manipulation practices.

The influences of the establishment of breast milk bank to the premature infants in the hospital / 中国实用护理杂志

Objective To discuss the influences of the establishment of breast milk bank to the premature infants in the hospital. Methods The clinical datas of 239 premature infants admitted in NICU from Feb 2017 to Jan 2018 were retrospectively analyzed. Dividing them into two groups, one was control group that the premature infants born before the establishment of breast milk bank, the other was observation group that the premature infants born after that. Both groups were taken the same treatment;and fed the autogenous breast milk or donated breast milk or premature milk based on the intention of infant′s family. Results In observation group,the breastfeeding rate was 67.5％ (85/126),the average hospital-stay time was (24.5±4.4) days.But in control group, the breastfeeding rate was 34.5％(39/113),the average hospital-stay time was (36.3±8.3) days, there were significant differences between the two groups (χ2=4.217, t=2.941, P<0.05).The complications in observation group included necrotizing enterocolitis (5 cases),bronchopulmonary dysplasia(3 cases), retinopathy of prematurity (5 cases) and sepsis (6 cases), the incidence of which was lower than that in control group. But, there was statistical significance in the incidence of necrotizing enterocolitis and sepsis only (χ2=3.989,5.386,P<0.05). Conclusions The establishment of breast milk bank can help to improve the breastfeeding rate of premature infants,shorten the hospital-stay time,reduce the incidence of NEC and sepsis,make premature infants recover more quickly.
