摘　　要：目的探讨早产儿脑白质损伤最佳颅脑超声检查时间,以期及时发现病变,对临床治疗、干预提供依据,减少早产儿神经系统后遗症。方法选取揭阳市人民医院新生儿中心2014-06—2016-06收治的80例早产儿为研究对象,在不同的时间进行颅脑检查,观察不同超声时间点并分析颅脑超声检查的最优时间。结果 80例早产儿超声诊断:脑室周围白质回声全程正常42例及脑室周围白质回声增强38例。其中,脑室周围白质回声增强出现在6~24(13.8±1.5)h,中位数12.5h;回声最强出现时间为2~5(3±1.4)d,中位数3d;回声增强持续时间为5~14(9±2.5)d,中位数9d;脑室周围白质囊性变出现时间为16~22(18±3.8)d,中位数18d;在28d内未发现囊腔消失。结论颅脑超声检查早产儿脑白质损伤在不同时间点有不同表现,应在合适时间内及时进行影像学检查。Objective To investigate the optimal time of brain ultrasound examination in preterm infants with periventrieular white matter iniury, and to find out the pathologic changes and provide basis for clinical treatment and imervention. Methods Eighty preterm infants from June,2014 to June,2016 in Jieyang People ＇s Hospital were enrolled in this study. Brain ex- aminations were performed at different time points, and the corresponding ultrasound findings were analyzed. Results Eighty pre- mature infants were diagnosed by ultrasound：42 cases of periventricul[ar white matter echo normal cases and 38 cases of periven- tricular white matter echo enhancement cases. Among them, the enhancement of white matter echo around the ventricle appeared in 6-24 h,（13.8±1.5）,median 12. S h;echo the strongest time for 2-5 d （3±1.4）,median 3d;echo enhancement duration of 5-14 （9 ± 2.5）, median 9 days; the time of capsule disappearance was 16-22 days （ 18 ± 3.8）, median 18d; No disappearance of the cyst was found within 28 days. Concision Brain ultrasound examination in preterm infants with periventricular white matter injury at different time points have different manifestations,it should be applied in correct time.
