> Hello! I am Twyla Mannie, a nursing student at the University of
> North Dakota. My client is expecting in a week. She is a teacher and
> considers returning to work prior to the end of the school year. She is
> concerned about having the time to pump at work as she feels she only has
> a twenty minute break for lunch during the day. She also is wondering how
> long she could store the expressed milk without refrigeration. I have
> asked a few questions and researched this area.
>       An instructor informed me that if my client breastfed before and
> after work, expressing once while at work would suffice. According to
> Bocar (1997), breast milk should ideally be expressed every three hours
> and mimic the infant's feeding frequency to ensure supply. I want to know,
> if pumping once is enough, what must the duration be? Does this correlate
> with the amount expressed and the infant's current intake?  Bocar
> (1997) states, "Mothers using a single pump may require 15 to 30 minutes,
> whereas mothers using a large motor-driven electric breast pump and
> pumping both sides simultaneaously may finish in 5 to 10
> minutes" (p. 25). Also, if the breasts begin to feel full prior to the
> scheduled break, would expression lasting a few minutes decrease pressure
> adequately until the later time?
>       As for storage, Bocar (1997) notes that fresh breast milk could be
> stored at room temperature for 4 to 6 hours. Hamosh, M., Ellis, Pollock,
> Henderson, and Hamosh, P. (1996) concluded that fresh breast milk should
> be stored no longer than four hours at twenty-five degrees
> Celsius. However, storing the breast milk in a cool box, increased the
> safe storage time to twenty-four hours (Hamosh, M. et al., 1996).
>       With the dramatic decrease in duration of lactation correlated
> with mothers who are employed full-time (Chezem, Montomery, and Fortman,
> 1997), any hints to keep this mother motivated would also be helpful.
>       After finding conflicting recommendations, I am very interested in
> your experiences. Information regarding frequency and duration of
> pumping, storage of expressed milk, and strategies to ease the transition
> back to work would be greatly appreciated. Thank you. Twyla Mannie,
> College of Nursing Student, University of North Dakota.
