对在风疹流行期怀孕与非流行期怀孕的妇女所产63例新生儿脐血进行风疹抗体（RV－IgG）测定，及对150例婴幼儿听力测试调查，发现流行期脐血RV－IgG滴度阳性率为86．8％，非流行期为20．0％（P＜0．05）；脐血RV－IgG滴度阳性组ABR异常检出率为32．1％，阴性组ABR无异常（P＜0．01）；流行期正常新生儿ABR异常检出率为35．7％，非流行期为3．5％（P＜0．001）。说明流行期孕妇感染风疹人数明显增多；风疹宫内感染呼致胎儿内耳发有障碍；流行期新中儿听觉障碍发生率较非流行期显著升高。提示做好孕期的预防风疹等感染工作，对于做好优生优育，提高人口素质十分重要。
63 cases of neonatal umbilical blood produced by pregnant women who were pregnant and non-epidemic during the epidemic of rubella were tested for RV-IgG, and 150 cases of infant hearing tests were detected. The prevalence of RV-IgG drops The positive rate was 86.8% in non-epidemic period and 20.0% in non-epidemic period (P <0.05). The positive rate of ABR in cord blood RV-IgG titer positive group was 32.1% (P <0.01). The prevalence of abnormal ABR in normal neonates during the epidemic period was 35.7% and in non-epidemic period was 3.5% (P <0.001). Indicating that the prevalence of pregnant women infected with rubella significantly increased the number of; urticaria intrauterine infection induced fetal inner ear hair disorders; prevalence of newborns with hearing impairment was significantly higher than non-epidemic period. Prompted to do a good job during pregnancy prevention rubella and other infections, for good prenatal and postnatal care, improve the quality of the population is very important.
