To evaluate the effect of uterine contractions on the incidence of preterm delivery within 7 and 14 days in twin pregnancies.
Study patients were identified from a large database composed of women receiving outpatient surveillance with home uterine contraction monitoring. We included tracings collected on a routine or acute basis from twin pregnancies without cerclage at 24.0-36.0 weeks. Tracings from patients with indicated delivery were excluded. Fisher's exact and Pearson's X2 tests were used.
Datafrom 2,423 patients who recorded 8,291 acute tracings and 12,649 routine tracings were analyzed. Preterm delivery within 7 days followed 1.4% of routine vs. 6.6% of acute tracings (p < 0.001). Preterm delivery within 14 days followed 5.1% of routine vs. 16.8% of acute tracings (p < 0.001).
Preterm uterine contractions affect pregnancy prolongation and outcome in twin pregnancies utilizing outpatient surveillance. Evaluation of patients exhibiting elevated preterm uterine contractions is warranted.
评估子宫收缩对双胎妊娠7天和14天内早产发生率的影响。
研究对象来自一个大型数据库，该数据库由接受家庭子宫收缩监测门诊监护的女性组成。我们纳入了24.0 - 36.0周未行宫颈环扎术的双胎妊娠患者常规或急诊采集的宫缩图。排除已明确分娩患者的宫缩图。采用Fisher精确检验和Pearson卡方检验。
分析了2423例患者记录的8291次急诊宫缩图和12649次常规宫缩图的数据。7天内早产在常规宫缩图后发生率为1.4%，急诊宫缩图后为6.6%（p < 0.001）。14天内早产在常规宫缩图后发生率为5.1%，急诊宫缩图后为16.8%（p < 0.001）。
早产子宫收缩影响双胎妊娠门诊监护的妊娠延长和结局。对早产子宫收缩增强的患者进行评估是必要的。
