【摘要】 为探讨剖宫产和经阴分娩对乙肝病毒 (HBV)母婴传播的影响 ,选择 2 4 1例 HBV- DNA阳性产妇分娩的新生儿 ,应用 PCR方法检测其脐血、静脉血 HBV- DNA。结果显示 ,181例经阴分娩的新生儿出生后 2 4小时及1个月时分别有 5 4、6 1例血液中 HBV- DNA阳性 ,而 6 0例剖宫产的新生儿有 9、11例阳性 ,两组比较差异有显著性 (P<0 .0 5 )。提示经阴分娩的新生儿比剖宫产出生的新生儿有更高的 HBV感染率。剖宫产是阻断 HBV母婴传播的有效措施更多还原

【Abstract】 To study the effect on HBV mother to infant transmission in cesarean section and vaginal delivery 241 newborns whose mothers were positive of HBV DNA were collected The HBV DNA in cord blood and venous blood of the newborns was examined by PCR Results showed 54 and 61 cases of 181 cases from vaginal delivery was positive in 24 hours and 1 months after birth 9 and 11 cases of 60 cases from cesarean section was positive The difference of the two groups was significant(P<0 05) This suggests the infection rate of newborns from cesarean section is lower than that from vaginal delivery Cesarean section is an effective labor presentation to block HBV mother to infant transmission更多还原
