Breastfeeding and Antepartum Breast Milk Expression (BABE): A Randomized Control Trial Utilizing an Electric Breast Pump and its Effect on Postpartum Breastfeeding.

Objective

To evaluate the effect of antenatal breast milk expression (ABE) on exclusive breastfeeding. Materials and

Methods

A randomized control study was performed with the primary outcome being formula use during the postpartum hospital stay. Secondary outcomes were the exclusive breastfeeding rate at 6 months postpartum and peripartum safety outcomes. Participants included multiparous and nulliparous patients who planned to breastfeed. Exclusion criteria included exclusively breastfeeding in prior pregnancies for greater than 6 months, medical contraindications for breastfeeding, multiple gestation, history of preterm delivery, or any contraindication to vaginal delivery. ABE group participants were instructed to pump for 20 minutes, three times daily, starting at 37 weeks of gestation.

Results

Three-hundred four participants from two clinics were enrolled. There was no significant difference in formula use during hospital admission (odds ratio [OR] 0.64, 95% confidence interval [CI] 0.34-1.22) or in exclusive breastfeeding at 6 months postpartum (OR 0.66, 95% CI 0.34-1.29). Colostrum use was more prevalent in the ABE group (OR 5.31, 95% CI 2.63-10.76). ABE participants were more likely to present in spontaneous labor (OR 2.09, 95% CI 1.05-4.14).

Conclusion

ABE did not significantly improve exclusive breastfeeding rates, but safely provides women opportunities to become familiar with breastfeeding before delivery and can provide readily available colostrum. There was no negative secondary safety outcome related to ABE identified. Prenatal care providers can consider recommending ABE to patients with minimal to no experience with breastfeeding.
