Prevalência de hemorragia peri-intraventricular em recém‑nascidos de muito baixo peso e/ou com idade gestacional menor que 34 semanas e relação com o uso antenatal de corticoide e de sulfato de magnésio em maternidade terciária.

Abstract

Objectives: this study aims to determine the prevalence of peri-intraventricular hemorrhage (PIVH) in newborns very low birth weight (NVLBW) and/or less than 34 weeks of gestational age (GA). Also to check the relation or not between PIVH and the antenatal use of corticosteroids and magnesium sulfate. Methods: a retrospective and cross-sectional study carried out by reviewing medical records of tertiary maternity service for the period from 1st July to 31 December 2015. Results/Discussion: all 110 patients included had GA less than 34 weeks and 41 (37.3%) were diagnosed with PIVH and there was a predominance of grade 1 hemorrhage Papile (63.4%). There was a preponderance of PIVH in the birth weight range of 1000-1499g (48.8%) and GA range 28 weeks to 31weeks and 6 days (53.7%). Corticosteroid exposure rate in the included sample was 77.3%, similar to exposure in the group with PIVH (75.6%). Magnesium sulfate exposure rate was 41.8% in the total sample and 34.1 % in the group with PIVH. Conclusion: the relation between PIVH and preterm infants with GA less than 34 weeks corresponds to 37.3%. The vast majority of cases of PIVH found were in infants with birth weight less than 1500g (85.4%).
