本文分析344例逾期妊娠,比较前后二期处理的结果。前期(1982～1984正)为150例过期妊娠,全部从42周时引产。结果:新生儿死亡率为2%,死产率0.67%,低于国内的报道,但仍高于同期新生儿总死亡率的3倍,剖宫产率亦为同期的3.2倍。后期(1985～86)过期妊娠34例及过期413～6周160例,均从逾期10天时引产,结果:新生儿死亡率为0.52%,低于同期总发生率,无死胎死产;新生儿窒息,胎儿窘迫、剖宫产率以及总手术率均明显低于前期(P<0.05～0.001)。结论指出,418周时引产较之42周有很多优点。
This article analyzes 344 cases of overdue pregnancy, compared to the results of the two before and after treatment. Early (1982 ~ 1984 positive) 150 cases of expired pregnancy, all from 42 weeks when the induction of labor. Results: The neonatal mortality rate was 2% and the stillbirth rate was 0.67%, which was lower than the national report but still higher than 3 times the total neonatal mortality rate in the same period. The cesarean section rate was 3.2 times higher than the same period. In the latter period (1985-86), 34 pregnant women who had expired pregnancy and 160 patients who had expired between 413 and 6 weeks had induced labor from 10 days after the expiration. The results showed that the neonatal mortality rate was 0.52%, lower than the total incidence in the same period, Asphyxia, fetal distress, cesarean section rate and total operation rate were significantly lower than the previous period (P <0.05 ~ 0.001). The conclusions point out that labor induction at 418 weeks has many advantages over 42 weeks.
