Abstract

Mothers of premature infants have difficulty maintaining their milk supply as a result of the separation that occurs between the mother and the baby. The hypothesis in the present investigation is that use of a bilateral (simultaneous) breast pumping system will increase the volume of milk expressed in these mothers. Thirty-two breastfeeding mothers of premature infants were randomly assigned to either the control (single) or the experimental (bilateral) breast pump group. Mothers pumped at least four times a day. Data collection included a daily milk production log, weekly serum prolactin levels, and a weekly State-Trait Anxiety Inventory (STAI). Participation lasted from four to six weeks. Data analysis included average STAI scores; average prolactin levels; and weekly averages for number of pumping sessions, hours of pumping, and milk production in milliliters. The two groups did not differ on several demographic characteristics, STAI scores, prolactin levels, number of pumping sessions per week, or weekly milk production. The amount of time spent pumping, however, was statistically less for mothers who used the bilateral pump (7.6 +/- 3.0 hours/week) versus those who used the single pump (11.1 +/- 3.1 hours/week) (p = .003). Although use of either the single pump or the bilateral electric pump resulted in similar milk production, the bilateral pump significantly reduced the time invested in pumping. Health professionals should advocate use of the bilateral pump for mothers of premature infants. Additional studies are needed to determine strategies for increasing milk production in this population.
