PubMed 2014 Quantitative, Prospective Cohort study 78 met eligibility criteria: 36 agreed to participate, 26 completed the process.
Took place in the NICU or at mothers home or pumping room. Breast milk expression volumes were recorded and analyzed Significantly higher volumes were expressed when close to infant, more when doing Kangaroo care (holding infant) Mothers should be encouraged to pump while holding infant or sitting next to infant. Unfortunately there often is a lack of privacy and the pumping rooms are not close to the NICU. Many hospitals provide pumping rooms but do not consider the proximity to the infant. This article clearly shows the importance and the difference this makes. Kangaroo care is just becoming more acceptable practice in many NICU’s.

Setting is a NICU in a children’s hospital Nurses lactation knowledge, the perception of support in the NICU The mother’s felt the atmosphere was much more supportive following the education the nurses received. The education seemed to have a long lasting effect on attitudes and intentions, but the knowledge scores tested 3 months later dropped showing retention was not as expected. The authors feel the nurses in the NICU must be educated in order to supply the support the mothers need for breastfeeding. They should have access to continued education and support from managers.
They admit the study has limitations with the small samples size and lack of diversity.
There was also a lack of a control group. Theses nurses had mostly never had specific education regarding lactation. I believe, as a nurse, this study showed important results. It is vital to these babies that the nurses be knowledgeable and supportive. Continuing to offer educational information is the only way to keep the evidence based findings current for all the staff.
