Ann writes:  Barbara Ackerman and Paula Meier...recommend that mothers with
babies separated from them due to medical problems should start pumping at
6 hours postpartum and then to pump 10-12x/day for 20 minutes with a
hospital grade double electric pump...Here are my questions.  Has there
been any comparative studies to only hand
expressing Vs ele breast pumps, especially in the first 48 hours?

Two things.  First, researcher Pam Hill spoke at my ILCA affiliate meeting
last spring.  There she shared with us the results of a study she was in
the process of finishing.  (I don't think it's been published yet.)  She
found that when  mothers of premies waited longer than 6 hours to start
pumping, they were at higher risk for insufficient milk production later.
I'm guessing that this is in part the basis of Paula's recommendation.  To
clarify, these were mothers who were pumping long-term and whose babies had
not gone to the breast.

Second. there was one old study (Green, D. et al.  The relative efficacy of
four methods of human milk expression. Early Hum Dev 1982; 6: 153-59) that
compared the results of expressing milk with a double electric pump (in
this case an Ameda SMB) a Loyd-B pump, an Evenflo pump, and manual
expression.  They found that mothers expressed considerably more milk with
higher fat content with the double electric pump than with the other
methods.  The other three methods were comparable.  However, I don't think
this study was done in the first 48 hours postpartum.

Hope this helps,
