The purpose of this prospective work is to communicate the experience with preinduction treatment with Folly's catheter on the Pelvic score (Ps), labor and neonatal outcome in 52 cases in 27 to 34 wg, preterm premature labor and unfavourable cervix. The first control group consist of 24 pregnancies with the same characteristics but with favourable cervix at the begging of labor induction and the second control group include 31 cases with spontaneous premature labor. The Folly's catheter is introduced through the cervical canal and the bulb inflated with 75 ml of sterile normal saline. After the Foley's catheter dropped out the Ps is reassessed and proceed with oxytocin infusion. In the first control group with favourable cervix the induction of labor is only with oxytocin via infusion pump. More than half of all patients are treated with with tocolysis. The results show that for the period of tocolysis and/or PPROM there is significant improvement of the Ps (from 0.90 +/- 0.9 to 2.35 +/- 1.5). The change in the Ps doesn't depend on the g.w., the length of tocolysis or on the initial Ps. The balloon catheter improve the Ps from 2.35 +/- 1.5 to 6.24 +/- 1.3 for y period of 3 h 20 min (2 h 40 min to 4 h, 95% confidence). After the Foley catheter dropped out the duration of labor with oxytocin infusion is 6 h (5 to 7 h, 95% confidence) and is not different from this in the control groups. The time for the catheter to drop out, the achieved Ps and especially the effacement of the cervix are essential features in the prognosis of the difficulties in the labor process and the neonate state.
这项前瞻性研究的目的是交流对52例孕27至34周、早产且宫颈条件不佳的患者进行福乐氏导管引产术前治疗对骨盆评分（Ps）、分娩及新生儿结局的经验。第一对照组由24例具有相同特征但引产开始时宫颈条件良好的妊娠组成，第二对照组包括31例自然早产的病例。将福乐氏导管经宫颈管插入，球囊注入75毫升无菌生理盐水。福乐氏导管脱出后重新评估Ps，并开始静脉滴注缩宫素。在宫颈条件良好的第一对照组中，仅通过输液泵静脉滴注缩宫素引产。超过半数的患者接受了宫缩抑制剂治疗。结果显示，在宫缩抑制剂治疗期和/或胎膜早破期，Ps有显著改善（从0.90±0.9提高到2.35±1.5）。Ps的变化不取决于孕周、宫缩抑制剂治疗时间或初始Ps。球囊导管在3小时20分钟（2小时40分钟至4小时，95%置信区间）内将Ps从2.35±1.5提高到6.24±1.3。福乐氏导管脱出后，静脉滴注缩宫素的分娩时间为6小时（5至7小时，95%置信区间），与对照组无差异。导管脱出时间、达到的Ps，尤其是宫颈消退情况是分娩过程困难及新生儿状态预后的重要特征。
