连续超声波脑扫描表明,约40%孕期≤32周的新生儿出生头3天脑室及其周周出现回声密度改变,事后死亡病例尸检发现脑室周围出血。早产儿出生头3个月的血浆维生素E(VE)浓度较低,故作者试在早产儿应用肌肉注射VE,结果降低了早产儿脑室内出血的发生率。作者选择210例孕期≤32周、出生后脑扫描无出血迹象的婴儿,随机分成补充VE组和对照组,两组人
Continuous ultrasound brain scan showed that about 40% of neonates born during the first trimester of pregnancy ≤ 32 weeks had an echo density change in the first 3 days of the brain and around the periorbital space. Post-mortem findings of post-mortem cases revealed periventricular hemorrhage. Preterm infants born in the first 3 months of plasma vitamin E (VE) concentration is low, so the authors try to use intramuscular injection of VE in preterm children, the results reduce the incidence of intraventricular hemorrhage in preterm infants. The authors selected 210 pregnant women ≤ 32 weeks of pregnancy, post-natal brain scan signs of bleeding in infants were randomly divided into supplemented VE group and control group, two groups of people
