Abstract
Objective
To examine among infants born very preterm the role of hemodynamic disturbances in the occurrence of cerebellar hemorrhage (CbH) and whether cardiovascular instability is associated with larger CbH volume.
Study design
Prospective, longitudinal, multisite cohort study. Early-life and/or term-equivalent age brain magnetic resonance imaging were performed in 309 very preterm infants admitted to 3 tertiary-level neonatal intensive care units. A cut-off of 4 mm was used to distinguish punctate vs large CbH. CbH volumes were obtained by manual segmentation. As a measure of hemodynamic stability, Score for Neonatal Acute Physiology, patent ductus arteriosus requiring treatment, and hypotension treated with inotropes were recorded.
Results
Sixty patients (18.3%) were diagnosed with CbH, classified as punctate in 43 infants (71.3%). Hypotension requiring treatment with inotropes was an independent risk factor for CbH (OR 3.07, 95% CI 1.15-8.21, P = .02) and was associated with larger CbH volume (0.36 log mm3, 95% CI 0.17-0.54, P < .001).
Conclusions
Hypotension treated with inotropes is shown to be an independent risk factor for the presence of CbH as well as for larger CbH volume. These results reinforce the importance of hemodynamics stability, especially an appropriate management of hypotension to prevent CbH and therefore improve neurodevelopmental outcomes among infants born very preterm.
期刊介绍:
The Journal of Pediatrics is an international peer-reviewed journal that advances pediatric research and serves as a practical guide for pediatricians who manage health and diagnose and treat disorders in infants, children, and adolescents. The Journal publishes original work based on standards of excellence and expert review. The Journal seeks to publish high quality original articles that are immediately applicable to practice (basic science, translational research, evidence-based medicine), brief clinical and laboratory case reports, medical progress, expert commentary, grand rounds, insightful editorials, “classic” physical examinations, and novel insights into clinical and academic pediatric medicine related to every aspect of child health. Published monthly since 1932, The Journal of Pediatrics continues to promote the latest developments in pediatric medicine, child health, policy, and advocacy.
Topics covered in The Journal of Pediatrics include, but are not limited to:
General Pediatrics
Pediatric Subspecialties
Adolescent Medicine
Allergy and Immunology
Cardiology
Critical Care Medicine
Developmental-Behavioral Medicine
Endocrinology
Gastroenterology
Hematology-Oncology
Infectious Diseases
