Morbimortalidad asociada al parto prematuro y su relación con el uso de corticoides y sulfato de magnesio

Abstract

IntroductionPreterm labour is associated with multiple complications, with an increased risk of perinatal morbidity and mortality. Nevertheless, many studies support the use of corticosteroids and magnesium sulphate to improve outcomes in preterm birth. The objective of this study is to describe the morbidity and mortality incidence in preterm birth in a Spanish hospital and how the use of corticosteroids and magnesium sulphate has improved the short-term prognosis in these newborns. Material and methodsObservational retrospective study of 564 preterm births between the years 2018 to 2019, in the hospital area Juan Ramón Jiménez (Huelva). The treatment with corticosteroids and magnesium sulphate was performed based on current protocols of the Spanish Society of Gynaecology and Obstetrics. ResultsThe incidence of prematurity in this study was 7.9%. Twin pregnancies and hypertensive pregnancy disease were the most common obstetric disorders. The most common type of delivery was caesarean section in all prematurity groups, except late prematurity. Respiratory distress syndrome was the most frequent pathology (more than 33%) in all groups. Overall neonatal mortality was 1.8‰. As regards the use of corticosteroids, the main outcome was a decrease in neonatal morbidity and mortality, which was statistically significant in respiratory distress syndrome and preterm retinopathy. The use of magnesium sulphate caused a decrease in the incidence of intraventricular haemorrhage, periventricular leukomalacia, and bronchopulmonary dysplasia. There were no significant differences in neonatal mortality. ConclusionsMorbidity and mortality registered in this study were similar to that described in the literature. Although the use of corticosteroids reduced neonatal morbidity and mortality in this study, it was only statistically significant in premature retinopathy and respiratory distress syndrome. The use of magnesium sulphate also showed an improvement in some pathologies and in mortality, but were not statistically significant.
