Abstract

Nipple shields (shield) may reduce pain during breastfeeding, but the impact on infant sucking dynamics is not known. We examined the effects of shield use on sucking dynamics, milk removal and nipple pain in two groups of breastfeeding dyads; Pain Group (PG) shield used for nipple pain; Comparison Group (CG): no breastfeeding difficulties. Twenty PG (6±4 weeks postnatal) and 28 CG dyads (8±6 weeks postnatal) attended 2 monitored breastfeeding sessions with shield use randomized. Within-subject outcomes were compared. PG: shield use did not affect intra-oral vacuum (peak p=0.17, baseline p=0.59), sucking frequency (p=0.20) or milk transfer (40 mL vs 48 mL, p=0.80; percentage of available milk removed (PAMR) 55% vs 57%, p=0.88), and reduced McGill pain scores (p=0.012). CG: shield use increased non-nutritive sucking (10% more, p=0.049), and reduced nutritive sucking (18% less, p=0.017) and milk transfer (63 mL vs 31 mL p<0.001, PAMR 65% vs 36% p<0.001). For both groups feeding duration increased by 2 min (p <0.0001) and non nutritive portions of the feed increased with shield use. Conclusion: Nipple shield use improved maternal comfort and did not impact milk removal or sucking strength in PG, but significantly reduced milk transfer and nutritive sucking in CG.
