Is your pump not removing milk well or is pumping painful? Consider a smaller fl**ge size.
A recent study looked at the pump comfort and milk volume output for 36 individuals who pumped with both a smaller fl**ge as well as the "standard fl**ge" size, recommended by the pump manufacturer. This was a cross-over study, meaning that during the study each participant in the study used both the smaller and standard fl**ges.
Measurement method for the 36 participants involved measuring the tip of the ni**le and then trialing that size and 1 to 2 sizes above and below the size of the ni**le tip, while identifying the most comfortable size with the most milk sprays. The "standard-fit fl**ges" per the pump manufacturer instructions ranged from 21 to 28 mm fl**ges.
Study design:
Each participant pumped for 1 week, at least 3 times during this week, with both the smaller fit and standard fit fl**ges. Participants were randomized to start with either the standard fit or smaller fit fl**ges.
Results:
~ The two most common sizes used for this smaller-fit fl**ge in the study cohort were 15mm and 17mm fl**ges.
~All smaller fit fl**ges were less than 21mm.
~The average milk production for pumping sessions using the standard fl**ges was 138mL (approx 4.6oz) while the average milk production for pumping sessions using the smaller fl**ges was 153mL (approx 5.1oz).
~The average comfort rating for the standard fl**ge was 3.3/5, while the average comfort rating for the smaller fl**ge was 4.5/5.
Summary:
This study while small supports consideration of the use of smaller fl**ges than those typically offered by pump manufacturers for lactating parents. It also reinforces the importance of patients being fitted for a pump, which we are happy to do at Breastfeeding Medicine of Northeast Ohio!
