ABSTRACTObjective: Evaluation of risk factors for intraventricular hemorrhage in preterm less than 33 weeks gestational age (RNP). Methods: Case-control study. We included RNP from a tertiary care center, classified by the results of transfontanellar sonography. Case: presence of intraventricular hemorrhage. Control: absence of intraventricular hemorrhage. We investigated prenatal history, perinatal and postnatal. Logistic regression was used to adjust the variables associated with intraventricular hemorrhage; we calculated odds ratios (OR) with confidence intervals of 95% (95% CI). Results: We analyzed the medical records of RNP 64; of these 32 were cases. The risk factors associated with intraventricular hemorrhage were: sepsis (OR: 18.45; 95% CI: 4.01-32.82; p = 0.01), respiratory distress syndrome (OR: 2.24; 95% CI: 1.07-4.95; p = 0.04), use with mechanical ventilation (OR: 3.60; 95% CI: 1.46-8.91; p = 0.01), and exogenous surfactant (OR: 2.32; 95% CI: 1.05-6.14; p = 0.03). Conclusions: The postnatal factors were associated with higher risk for intraventricular hemorrhage in RNP. The transfontanellar sonography should be taken at different times to know with precision the risk factors for this pathology and try to avoid them.
