Here is what I want to know about nipple shield studies: When a nipple shield is used, is the mother advised to pump after use of the shield? I have been doing some testing with moms with shield and without - just validating from mom's point of view what the difference in vacuum is with a shield and without. It is a difference of 40 mmhg for most moms. What that means is that when a shield is used, there is less vacuum applied to the nipple by the baby through the shield, which limits the speed of milk ejection to the baby. I have used a nipple shield to help moms who have a high milk supply to LOWER their supply and give baby better control. SO, if moms who have an average or low supply use a shield, not only do they reduce what baby gets at the breast BUT they reduce their supply unless they pump after feedings (the number of pumping depends on overall supply). If a study does not include this as a variable (the mom's use of a pump and the type of pump used), you CAN'T say that it is the nipple shield itself that causes the issues. Why use the shield in the first place? I don't use them unless there is NO OTHER WAY to get the baby on the breast. And I'd rather have a baby happy at the breast than mom pumping and bottlefeeding! And in almost every case, babies will get off the shield if mom has a good supply and is happy and confident in her breastfeeding.

Healthy-e learning posted a study on nipple shield use where the study was
done in a hospital clinic staffed only by experienced IBCLC's. 12 month
period. 1218 women seen with problems but only 44 were given shields. Half of those babies gained weight of at least 1 oz, 25 % lost weight and 22 remained at same weight; This gives a total of 47 % with failure to thrive.
I am wanting to post this study to get acrossed to our staff that nipple shields are not the first route to go when helping a baby who won't latch in the first 24 hours...:( or so. However, I threw away my bibliography page and can't reference the study. Does any one know the one I am talking about?

No, I don't know the study, but would LOVE to have a copy of it. I did the nipple shield clinical workshop at ILCA this last week, and someone mentioned that someone had mentioned a study similar to this, and I'm eager to read it. Really want to know what kind of shields were used, how they ascertained that the no weight gain or loss of weight was related to n.s. use, and not low supply on the part of the mom, etc. So if anyone knows what study this is referencing, you have at least two people that want it!!
