摘要


我們自民國七十九年二月起,對本院新生兒病房的早産兒(懷孕週數低於37週,體重小於2500公克)進行前瞻性顱部超音波檢查。於嬰兒出生第一天至第四天,及第七天做常規的超音波檢查。如有異常者,每週至少做一次追蹤檢查。所有的嬰兒於出院前皆再接受一次追蹤檢查。在23個月中,一共有134位早産兒接受檢查。其中10例(7.5%)有腦室出血。 體重小於1500公克者13%有腦室出血。懷孕週數低於32週者,11.3%有腦室出血。90%的及室出血發生於出生後72小時之內。低懷孕週數及低血氧與腦室出血之發生有明顯關係。在門診追蹤發現,七個第一級腦室出血之早産兒中有六位之精神運動發育皆正常。三位第三級腦室出血之早産兒中有一位之精神運動發育明顯遲緩。常規之顱部超音波檢查對早産兒之評估及預後而言,是一項實用且重要之檢查。

A prospective brain sonograph study was performed on 134 preterm neonates with birth weight of less than 2500 gm. Ten (7.5%) infants had intraventricular hemorrhage (IVH). The incidence of IVH in preterm neonates weighing less than 1500 gm was 13% and in neonates of less than 32 weeks gestation was 11.27%. Ninety percent of the IVH occurred within the first 72 hours of life. Prematurity, and hypoxia were considered as significant contributing factors for neonatal IVH. Six of the 7 infants with IVH grade Ⅰ have a favorable neurological outcome. One of the 3 infants with IVH grade Ⅲ has psychomotor delay. Routine brain sonograph study is considered practical and invaluable for diagnosis of IVH in preterm neonates.
