摘要
目的调查住院早产儿脑损伤发生率及其影响因素。方法对1996～2996年10年间入住新生儿病房、曾经头颅B超检查的所有住院早产儿进行分析,应用SIGMAB超诊断仪对早产儿进行头颅B超检查。结果196例早产儿的平均胎龄为(34.0±2.1)周,平均出生体重为(2.13±0.53)kg。平均头颅B超初次检查时间为生后(5.3±6.3)d,其中本院出生患儿为(4.0±2.0)d,外院出生患儿为(7.0±8.0)d,两者有非常显著性意义。总的脑损伤发生率为56.6%,重度脑损伤发生率为16.3%。早产儿的胎龄愈小,出生体重愈低,其脑损伤发生率愈高,出血程度也趋严重。围产期窒息、家中自娩、机械通气、产妇为外来民工等因素与早产儿脑损伤及出血程度密切相关。结论鉴于早产儿脑损伤的高发率及约一半脑损伤早产儿无明显临床症状,建议对早产儿在生后早期应常规进行头颅B超检查。
Objective Toexlore the incidence of craniocerebral injury andriskfactors craniocerebral injury in hospitalized premature infants. Methods All clinical date were collected and analyzed in196 hospitalized premature in-fants on whom the bedside cranial ultrasound had been undertaken in their early age after birth during Nov.1996 to Mar.2006. Results the average gestional age of 196 infants was 34.0±2.1 weeks and average birthweight 2.13±0.53kg. The initial bedside real-time cranial senogran was recorded was 5.3±6.3 days, in whichutborn babies were sig-nificantly delayed [（7,0±8.0）d] than inborn invants [（4.0±2.0）d]. The overall incidence of Craniocerebral injury was 56.6% and the proportion of severe Craniocerebral injury was 16.3%. The well-known inverse correlation between Craniocerbral injury and birthweight and gestational age were again demonstrated. The lower the birthweight was, the higher the incidence of Craniocerebral injury would be, and hemorrhage tended towards serious. Craniocerebral injury occurred more often in infants with perinatal asphyzia delivery at home and mechanical ventilation, etc. in particular there was a marked correlation between Craniocerebral injury and infants whose nothers were non-regular laborers with poor prenatal care. Conclusions Since there is a higher incidence of Craniocerebral in jury in premature infants and nearly half cases among them were usually no obuious symptom clinically, it is suggested that a rou-tine examination cranial ultrasound be necessary for each premature infant at their early age.
