Abstract
Objective To investigate the risk factors and outcomes of ventricular dilatation (VD) in premature infants. Methods Three hundred and thirteen premature infants, who underwent head ultrasonography examination at d3~d7 after birth in NICU during November 2008 and November 2009. The clinical characteristics were retrospectively reviewed and risk factors were analyzed with non- conditional logistic regression. Results There were 24 episodes of VD (7.67%) in 313 premature infants. The incidence of VD was 24.4% (20/82) in infants with gestational age at birth <30 weeks and the incidence of VD was 15.8%(20/127) in infants with birth weight<2 000g. Single factor analysis showed that VD in premature infants was significantly associ-ated with gestational age, birth weight, blood PH values, blood sugar, anemia and mechanical ventilation. Multivariate logistic re-gression analysis revealed that low gestational age, low birth weight and mechanical ventilation were independent risk factors for VD. Conclusion VD occur at significant rates among premature infants and is associated with low gestation age, low birth weight and mechanical ventilation.关键词
