Intercurrences and main neonatal procedures in the late preterm newborn compared to newborn at term
Main Article Content
Abstract
Introduction: late preterm newborns currently account for around 70% of all premature babies and, when compared to newborns at term, show an increased risk of neonatal complications. Objective: to compare the neonatal morbidity profile of late preterm newborn to newborn at term. Methods: a descriptive, cross-sectional study involving all newborns from the gestational age of 34 weeks, born between February and June 2016 in the maternity ward of an university hospital. They were divided into two groups, according to the gestational age, in late preterm newborns (34 0/7 to 36 6/7 weeks) and newborns at term (37 0/7 or more weeks), and the data was collected from the records of newborns and their mothers. The prevalence and the odds ratio of morbidity occurring in the groups was calculated. Results: the prevalence of late prematurity was 8.8%, out of a total of 898 births. When compared to newborns at term, the late preterm newborns had more chances of requiring hospitalization in neonatal ICU and ventilatory assistance (OR = 26.0), resuscitation (OR = 3.0), and to present hypoglycemia (OR = 9.8), neonatal jaundice with phototherapy (OR = 10.8), neonatal sepsis (OR = 8.8), sucking difficulty (OR = 13.8), food supplementation (OR = 9.4) and need for blood collection for complementary tests (OR = 22.5). Conclusions: late preterm newborns should be remembered as newborns who need to receive special attention during their care, due to the greater frequency of
morbidity to which they are subject.
