Diabetes and antenatal milk expressing: a pilot project to inform the development of a randomised controlled trial

OBJECTIVE infants of women with diabetes in pregnancy are at increased risk of hypoglycaemia. If the infants blood glucose is low and the mother is unable to breast feed/provide sufficient expressed breast milk, infants are often given formula. Some hospitals encourage women with diabetes to express breast milk before birth. However, there is limited evidence for this practice, including its impact on labour and birth, e.g. causing premature birth may be a concern. A pilot study was undertaken to establish the feasibility of conducting an adequately powered randomised controlled trial to evaluate this practice. DESIGN consecutive eligible women with pre-existing or gestational diabetes (requiring insulin), planning to breast feed and attending the study hospital were offered participation. INCLUSION CRITERIA 34-36 weeks of gestation; singleton pregnancy; cephalic presentation; and able to speak, read and write in English. EXCLUSION CRITERIA history of spontaneous preterm birth, antepartum haemorrhage, placenta praevia and suspected fetal compromise. Women were encouraged to express colostrum twice a day from 36 weeks of gestation, and advised how to store the colostrum, which was frozen for their infants use after birth. They were asked to keep a diary documenting their expressing. DATA demographic questionnaire, telephone interview at six and 12 weeks postpartum and medical record data. SETTING a public, tertiary, womens hospital in Melbourne, Australia. PARTICIPANTS 43 women with diabetes in pregnancy (requiring insulin). FINDINGS cardiotocographs were undertaken after the first expressing episode and none of the infants showed any sign of fetal compromise. Forty per cent of infants received formula in the 24 hours postpartum. The proportion of infants receiving any breast milk at six weeks was 90%, and this decreased to 75% at 12 weeks. No women showed evidence of hypoglycaemia post expressing. The intervention was positively received by most women; 95% said that they would express antenatally again if the practice proved to be beneficial. The amount of colostrum varied according to the number of expressions, the length of time in the study and the time spent expressing, with a median of 14 days expressing and 39.6 ml of colostrum obtained. KEY CONCLUSIONS the small number of women in this pilot was not an adequate number to examine safety or efficacy, but this study does provide evidence that it would be feasible and desirable to conduct a randomised controlled trial of antenatal milk expressing for women with diabetes requiring insulin in pregnancy. IMPLICATIONS FOR PRACTICE it is important that this widespread practice undergoes rigorous evaluation to assess both efficacy and safety. Until such evidence is available, the authors suggest that the routine encouragement of antenatal milk expressing in women with diabetes in pregnancy should cease.

Feeding infants directly at the breast during the postpartum hospital stay is associated with increased breastfeeding at 6 months postpartum: a prospective cohort study

Objective To explore whether feeding only directly from the breast in the first 24–48 h of life increases the proportion of infants receiving any breast milk at 6 months. Design A prospective cohort study. Setting Three maternity hospitals in Melbourne, Australia. Participants 1003 postpartum English-speaking women with a healthy singleton term infant, who intended to breast feed, were recruited between 2009 and 2011. Women were excluded if they or their infant were seriously ill. 92% (n=924) were followed up at 6 months postpartum. Primary and secondary outcome measures Main exposure variable —type of infant feeding in hospital up to time of study recruitment (24–48 h postpartum), categorised as ‘fed directly at the breast only’ or ‘received at least some expressed breast milk (EBM) or infant formula’. Primary outcome—proportion of infants receiving any breast milk feeding at 6 months postpartum. Secondary outcomes—proportion of infants receiving only breast milk feeding at 6 months; breast milk feeding duration; and maternal characteristics associated with giving any breast milk at 6 months. Results Infants who had fed only at the breast prior to recruitment were more likely to be continuing to have any breast milk at 6 months than those who had received any EBM and/or infant formula (76% vs 59%; adjusted OR 1.76, 95% CI 1.24 to 2.48 (adjusted for parity, type of birth, breastfeeding intention, breastfeeding problems at recruitment, public/private status, epidural for labour or birth, maternal body mass index and education)). Conclusions Healthy term infants that fed only directly at the breast 24–48 h after birth were more likely to be continuing to breast feed at 6 months than those who received any EBM and/or formula in the early postpartum period. Support and encouragement to initiate breastfeeding directly at the breast is important.

Infant feeding practices in the first 24–48 h of life in healthy term infants

To examine in‐hospital infant feeding practices, focusing on initiation and prevalence of breastmilk expression and to describe the proportion of women having a breast pump immediately after birth.

Safety and efficacy of antenatal milk expressing for women with diabetes in pregnancy: protocol for a randomised controlled trial

Introduction Many maternity providers recommend that women with diabetes in pregnancy express and store breast milk in late pregnancy so breast milk is available after birth, given (1) infants of these women are at increased risk of hypoglycaemia in the first 24 h of life; and (2) the delay in lactogenesis II compared with women without diabetes that increases their infants risk of receiving infant formula. The Diabetes and Antenatal Milk Expressing (DAME) trial will establish whether advising women with diabetes in pregnancy (pre-existing or gestational) to express breast milk from 36 weeks gestation increases the proportion of infants who require admission to special or neonatal intensive care units (SCN/NICU) compared with infants of women receiving standard care. Secondary outcomes include birth gestation, breastfeeding outcomes and economic impact. Methods and analysis Women will be recruited from 34 weeks gestation to a multicentre, two arm, unblinded randomised controlled trial. The intervention starts at 36 weeks. Randomisation will be stratified by site, parity and diabetes type. Women allocated to the intervention will be taught expressing and encouraged to hand express twice daily for 10 min and keep an expressing diary. The sample size of 658 (329 per group) will detect a 10% difference in proportion of babies admitted to SCN/NICU (85% power, α 0.05). Data are collected at recruitment (structured questionnaire), after birth (abstracted from medical record blinded to group), and 2 and 12 weeks postpartum (telephone interview). Data analysis: the intervention group will be compared with the standard care group by intention to treat analysis, and the primary outcome compared using χ2 and ORs. Ethics and dissemination Research ethics approval will be obtained from participating sites. Results will be published in peer-reviewed journals and presented to clinicians, policymakers and study participants.

Accreditation of midwife lactation consultants to perform infant tongue‐tie release

Infants with a tongue-tie or ankyloglossia have a short lingual frenulum, which can lead to problems with breastfeeding: attachment difficulties, nipple pain and damage, poor weight gain and eventually a reduction in milk supply. Trained clinicians can release the frenulum (frenotomy) in infants having difficulty with breastfeeding. Although traditionally performed by medical practitioners, we argue that this simple procedure is within the scope of practice of other clinicians. This paper outlines the process of setting up and maintaining credentialing for midwife lactation consultants (International Board Certified Lactation Consultants (IBCLCs)) to assess infant tongue-ties and perform frenotomy when appropriate at a tertiary maternity hospital. Since 2005, 11 midwives/IBCLCs have been credentialed to perform frenotomies at The Breastfeeding Education and Support Services at The Royal Womens Hospital in Melbourne, Australia. We believe that nurses/midwives/lactation consultants working in other settings could be trained to perform frenotomies, thus enabling faster resolution of breastfeeding problems.

Ringing Up about Breastfeeding: a randomised controlled trial exploring early telephone peer support for breastfeeding (RUBY) – trial protocol

BackgroundThe risks of not breastfeeding for mother and infant are well established, yet in Australia, although most women initiate breastfeeding many discontinue breastfeeding altogether and few women exclusively breastfeed to six months as recommended by the World Health Organization and Australian health authorities. We aim to determine whether proactive telephone peer support during the postnatal period increases the proportion of infants who are breastfed at six months, replicating a trial previously found to be effective in Canada.Design/MethodsA two arm randomised controlled trial will be conducted, recruiting primiparous women who have recently given birth to a live baby, are proficient in English and are breastfeeding or intending to breastfeed. Women will be recruited in the postnatal wards of three hospitals in Melbourne, Australia and will be randomised to peer support or to ‘usual’ care. All women recruited to the trial will receive usual hospital postnatal care and infant feeding support. For the intervention group, peers will make two telephone calls within the first ten days postpartum, then weekly telephone calls until week twelve, with continued contact until six months postpartum. Primary aim: to determine whether postnatal telephone peer support increases the proportion of infants who are breastfed for at least six months. Hypothesis: that telephone peer support in the postnatal period will increase the proportion of infants receiving any breast milk at six months by 10% compared with usual care (from 46% to 56%).Outcome data will be analysed by intention to treat. A supplementary multivariate analysis will be undertaken if there are any baseline differences in the characteristics of women in the two groups which might be associated with the primary outcomes.DiscussionThe costs and health burdens of not breastfeeding fall disproportionately and increasingly on disadvantaged groups. We have therefore deliberately chosen trial sites which have a high proportion of women from disadvantaged backgrounds. This will be the first Australian randomised controlled trial to test the effectiveness and cost effectiveness of proactive peer telephone support for breastfeeding.Trial registrationAustralian and New Zealand Clinical Trials Registry ACTRN12612001024831.
