Repercussions of newborn oxygenotherapy from a neonatal UTI

Abstract

Introduction: Oxygen therapy is an O 2 supplementation technique in concentration of more than 21%. Being widely used to the newborn with respiratory problems, the use of excess O2 can cause toxicity mainly in the retina and in the lungs. Objective: To verify the repercussions of oxygen therapy in newborns hospitalized in an ICU of a private hospital in the Federal District. Materials and methods: Retrospective and cross-sectional study with analysis of 100 randomly selected charts. The research was carried out in August 2016 at the Neonatal ICU of Brasília Maternity Hospital of the Federal District, through information such as: ventilation type, newborn weight, apgar, O2 device, gestational age, reason for indication, time of Use of O2 and diseases diagnosed by the use of O2. Data were tabulated in Excel 2007 worksheet and statistical analyzes were performed using SPSS 18.0. Results: It was observed that 90% were in NIV, 58% in MV, and 29% O2 free. The mean O 2 utilization was 22 ± 25.9 days. The mean age of those with Retinopathy of Prematurity and Bronchopulmonary Dysplasia was 70 ± 31.8 and 66 ± 31.9 days respectively, 69% of the newborns were preterm, with mean gestational age of 33.6 ± 4, 0 weeks. Apgar had a mean of 6.7 ± 1.8. With average weight of 2.258g ± 931.5g, being 59% low weight. Respiratory distress syndrome was the most common cause of O2 use, with 85% being the most used device. The diagnosed diseases were Bronchopulmonary Dysplasia and Retinopathy of Prematurity with 17% and 15% of the N, respectively, with an average Apgar 5 ± 1,5 in both. Conclusion: Oxygen therapy is very important for the recovery of newborns, but care should be taken with the use of O2 and associated factors that influence the development of lesions such as bronchopulmonary dysplasia and retinopathy of prematurity.
