ABSTRACT

Background. Inadequate suction may affect newborn (NB) growth, especially in low birth weight (LBW) infants. The aim of this study was to determine the relationship between suckling efficacy at 48 h of life with neonatal weight gain (WG) in infants exclusively breastfed with normal birth weight (NBW › 2.5 kg) and LBW (≤ 2.5 kg).
Methods. We carried out a cohort study in healthy NB rooming with their mothers in hospital. At 45-48 h after birth, prior to discharge and after being weighed, suckling efficacy was assessed using the ECLES scale by a previously trained physician. At 28 days of life, WG was assessed. We included only those infants who continued to be exclusively breastfed.
Results. There were 80 NB, 51 (63.7%) with NBW and 29 (36.3%) with LBW; 47 (58.7%) NB with normal suckling (ECLES 39-40), 24 (30%) with mild suckling impairment (ECLES 37-38), and nine NB (11%) with moderate suckling impairment (ECLES 32-36). There was a relationship between WG and suckling efficacy, most noticeable in LBW infants [WG for newborns with NBW and normal suckling = 1169 ± 222 g, mild impairment of suckling = 995 ± 257, and moderate impairment of suckling = 1073 ± 245; for LBW infants and normal suckling = 911 ± 229, mild impairment of suckling = 1010 ± 299, and moderate impairment of suckling = 460 ± 115. ANOVA ECLES* weight F = 3.8, p = 0.04, F_ECLES = 1.5, p = 0.39 y F_weight = 4.5, p = 0.12]. There were no diferences in parity, gestational age, gender and nipple condition of the mothers among infants, with or without normal suckling.
Conclusions. Mild or moderate suckling impairment after 48 h of life was associated with lower weight gain during the neonatal period, especially in LBW infants. Oral stimulation therapy is suggested in these children before discharge and with close follow-up.
