| 概要 |
Objectives : This study aimed to predict the gestational weeks by characterizing maternal genital bleeding and uterine contraction during pregnancy in patients with placenta previa. Methods : Included... in this study were 87 patients with placenta previa, diagnosed at the time of delivery at our institution. Genital bleeding and uterine contraction characteristics and clinical data from mothers who delivered at < 37 weeks were compared to that of mothers who delivered at ≧ 37 weeks. Results : There were 37 deliveries (42.5%) at < 37 gestational weeks and 50 deliveries (57.4%) at ≧ 37 gestational weeks. In 69 of 87 cases (79.3%), genital bleeding wasrecognized during pregnancy, and in 63 cases (72.4%) genital bleeding was the first symptom to occur during pregnancy. Uterine contraction during pregnancy was recognized in 48 cases (55.2%), including 36 (41.4%) that occurred as the first symptom of pregnancy. Logistic regression analysis revealed that when genital bleeding occurred at < 29 and < 31 weeks, patients were at high risk for delivery at < 34 and < 37 weeks, respectively, and when first uterine contraction occurred at < 29 weeks, they were at high risk for delivery at < 34 weeks. Conclusion : In patients with placenta previa, the number of gestational weeks to the occurrence of the first genital bleeding can be used as a predictor of the number of weeks to term.
前置胎盤は妊娠後半期における産科救急の代表的な疾患で, 母体出血および早産の点から, 母児双方に関してハイリスクな妊娠である. 経膣超音波断層法の普及を背景として, 本症の診断は容易かつ確実になされるようになった. しかしながら, 本症において安静入院時期の決定および早産予防の視点から分娩時期を予測する検討はなされていない. 本検討では, 妊娠経過中に母体に起きる性器出血および子宮収縮の2つの主症状に着目した. これらの症状の出現時期とその特徴から分娩時期を予測することを目的とし, 九州大学医学部附属病院周産母子センターにおいて過去10年間に経験した前置胎盤症例について後方視的に検討を行った.続きを見る
