Effects of Kangaroo Care on the development of oral skills and achievement of exclusive oral feeding in preterm infants

Efeitos do Método Canguru no desenvolvimento das habilidades orais e na aquisição da alimentação oral exclusiva em recém-nascidos pré-termo

ABSTRACT

Purpose  analyze the effects of hospitalization in the Kangaroo Neonatal Intermediate Care Unit (UCINCa), the second stage of the Kangaroo Care (KC), on the development of oral feeding skills in preterm neonates.

Methods  an analytical observational study of the prospective longitudinal type, carried out in a public hospital in Southern Brazil, where infants were accompanied until hospital discharge. The sample consisted of 20 preterm neonates hospitalized at the UCINCa and 26 preterm neonates at the Conventional Neonatal Intermediate Care Unit (UCINCo), that were periodically evaluated through the levels of oral skill, in a bottle, according to the criteria of proficiency and milk transfer rate. The outcomes considered were a progression of the oral skill level, days of transition to obtain the full oral route, and days of hospital stay.

Results  the duration of transition to exclusive oral feeding was shorter for preterm neonates at the UCINCa (4.5 vs. 10 days) relative to those at the UCINCo (p = 0.041). By the third assessment, all preterm neonates at the UCINCa had reached level 4, while participants at the UCINCo only achieved this level of performance on the fifth assessment. The average number of days of hospitalization was four days shorter in UCINCa participants (p=0.098).

Conclusion  the admission to the UCINCa had been a further acceleration in the maturation of oral skills, which allowed for a faster transition to exclusive oral feeding as compared to neonates admitted in UCINCo.
