Cuidado mãe canguru em recém-nascidospré-termo sob suporte ventilatório: Avaliação dos estados comportamentais

Abstract

Objectives: to describe the behavior ofnewborns weighing under 1500 g on mechanical ventilation, before and after kangaroo mother care (KMC). Methods: a quasi-experimental type study in which behaviors such as deep sleep, activity, drowsiness, inactive alertness, active alertness, and crying as defined by the Brazelton NeonatalScale were assessed on three separate occasions: 15 minutes before KMC, 30 after the beginning of KMC and 15 minutes after a total of one hour'sKMC. Forty-four preterm newborns (statistical power > 0.9), with a mean gestational age of 29 weeks and mean weight of 1096 g, intubated and stable in terms of hemodynamics were selected by way of continuous entry sampling. Results: the results provided evidence that KMC improves babies' sleep, especially deep sleep (52.3%), compared to the period prior to (6.8%) and after (13.6%) (p<0.001) KMC. Apart from this, the newborns showed signs of pain after KMC, with a significant difference (p=0.002). Conclusions:kangaroo mother care, under the conditions studied, may be considered a beneficial strategy for neuro-behavioral development.
