ABSTRACT
Objective To study the clinic value of brain edema detected by ultrasound examination in high risk term infants. Meth-ods The study group included 140 term infants who were found having brain edema in cranial ultrasound examinations. 152 term infants with normal ultrasound scan were selected as a control group. The risk factors of brain edema were collected, and univariate analysis and multivariate logistic regression analysis were performed. Results (1) There was no difference of incidence of brain edema between the infants with or without maternal ill historys, fetal distress or hypoalbuminemia, with P > 0.05. (2) In the univariate regression model, as-phyxia,hypoxic -ischemic encephalopathy (HIE) ,ventilation and metabolic acidosis were associated with an increased risk of brain ede-ma. In the multivariate logistic regression model, HIE was associated with a greater risk of brain edema and ventilation was possibly asso-ciated with brain edema. Conclusion Brain edema detected by ultrasound examination in high risk term infants has close relationship with HIE. It suggest that there is a consistency between ultrasound results and clinic situation. The detection of brain edema by ultrasound can assist doctor in clinic practice.
