目的 探讨围产期新生儿颅内出血的高危因素。方法 对 417例高危儿 ,从分娩方式、母亲孕期、产时并发症、胎龄、出生体重和血气检测值等进行回顾性分析。结果 臀位产、钳产、宫内窘迫、新生儿窒息、胎龄小于 32周、体重低于 15 0 0 g的早产儿、出生后 2 4h以内 Pa CO2 >6 .6 7k Pa、p H<7.2等是颅内出血的相关因素。结论 缺氧是引起颅内出血的主要因素 ,应加强胎儿的宫内监护和维持新生儿血气、血压的正常等预防工作。
Objective To investigate the risk factors of intracranial hemorrhage in perinatal neonates. Methods A total of 417 high risk infants were retrospectively analyzed from mode of delivery, mother’s pregnancy, obstetrical complications, gestational age, birth weight and blood gas. Results The breech production, forceps, intrauterine distress, neonatal asphyxia, gestational age less than 32 weeks, weight less than 1500 g of preterm infants within 24 hours after birth, Pa CO2> 6. 67k Pa, p H < 7.2 and so is related to intracranial hemorrhage. Conclusion Hypoxia is the main cause of intracranial hemorrhage. We should strengthen the intrauterine fetal protection and maintain the normal blood pressure and normal blood pressure of neonates.
