Repercussões neurocomportamentais e cardiorrespiratórias do posicionamento hammock em recém-nascidos pré-termos em uma unidade de terapia intensiva neonatal: estudo observacional

Abstract

Introduction: The Hammock positioning was used by Brazilian health professionals as a practice of humanized care in preterm newboRN (PTNB) in Neonatal Intensive Care Units (NICU). It is awarded for contributing to the improvement of the vestibular system, sensory integration, balance and proprioception, unwanted changes or retractions and promotion of tonic and behavioral reorganization. However, there is little scientific research on the topic. Objective: to analyze how neurobehavioral and cardiorespiratory repercussions of Hammock positioning in PTNBs in NICUs. Method: observational, prospective and analytical cohort study.As neurobehavioral variables using the Brazelton Neonatal Behavioral Assessment Scale (BNBAS), Neonatal Infant Pain Scale (NIPS), Neonatal Facial Coding System Scale (NFCS) and PIPP: Premature Infant Pain Profile and as variables Cardiorespiratory: respiratory rate (RF) and peripheral oxygen saturation (SpO2), were observed 5 minutes before, during (1 and 2 hours), at the last moment of positioning; and 5 and 30 minutes later. Data processing was performed using the SPSS program (Statistical Package for the Social Sciences 22). The data were presented as simple descriptive statistics (percentage -%, mean, standard deviation, median and interquartile range - IQR). As the medians were compared using the Friedman, Q Cochran and ANOVA tests for repeated measures, attributing results with p <0.05. Results: 45 PTNBs, born with gestational age between 25-35 weeks, were observed. PTNBs progressively progressed to deep sleep during network positioning (p = 0.007 Cochran's Q test). There was no significant change in pain scores (p> 0.05, Cochran's Q test). As cardiorespiratory variables kept within normal limits without changes (p> 0.05, Friedman's test and ANOVA for repeated measures). Conclusion: Hammock positioning indicates deep sleep and does not alter cardiorespiratory variables. Key words: Premature Newborn; Patient positioning; Neonatal Intensive Care Units; Physiotherapy.
