Background:
Early breast milk expression helps establish lactation and increase milk production.
Local Problem:
In mothers of infants admitted to this neonatal intensive care unit (NICU), 63% met target milk volumes on day 7 and 43% on day 14 postpartum.
Methods:
A pre/post quasi-experimental design was used.
Interventions:
Breast milk expression was initiated within 6 hours of delivery.
Results:
A total of 69 mothers were included (34 baseline; 35 post-implementation). Time to first milk expression decreased from 9.21 to 7.97 hours, P = .381. Milk volumes increased by 16.9% on day 7 (402.29 mL to 470.11 mL, P = .358) and 5.18% at 14 days postpartum (618.15 mL to 650.17 mL, P = .778).
Conclusions:
Initiation of milk expression within 6 hours of delivery may positively impact milk production among mothers of premature infants.
