围产儿感染是其死亡原因之一,占围产儿死亡的5～20%。因此,预防及早期发现宫内感染、积极治疗新生儿感染,是降低围产儿死亡率的重要环节。为早期发现宫内感染,我们检测了332例新生儿脐带血IgM数值,对IgM异常增高者结合临床进行分析,认为脐带血IgM的增高,可做为诊断宫内感染的免疫学指标,并找出我院新生儿IgM的界限值,供临床参考。 Perinatal infection is one of the causes of death, accounting for 5 to 20% of perinatal deaths. Therefore, prevention and early detection of intrauterine infection, and active treatment of neonatal infection, is an important part of reducing perinatal mortality. For the early detection of intrauterine infection, we detected 332 cases of neonatal umbilical cord blood IgM values, combined with abnormal IgM clinical analysis, that umbilical cord blood IgM increased, as an immunological diagnosis of intrauterine infection, and find Out of our hospital neonatal IgM limits for clinical reference.
