Report about a myometrial contractility-screening in 2462 asymptomatic pregnancies at 30 weeks of gestation. A cervical examination was performed in the 26th and 33th weeks of gestation. An increased uterine contraction frequency was obtained in 3% and a cervical opening in 5.6%. Uterine contractions with cervical opening are a high-risk factor of prematurity (52%-70%) whereas uterine contractions alone are of low-risk. The prevention of preterm birth is useful. We found a significant decrease of early neonatal mortality in 487 singleton preterm deliveries after treatment. A classification of unexplained preterm delivery, iatrogenic or elective preterm delivery and complicated preterm labor is recommended for controlled outpatient and clinical trials.
关于2462例妊娠30周无症状孕妇子宫肌层收缩力筛查的报告。在妊娠第26周和第33周进行了宫颈检查。子宫收缩频率增加的占3%，宫颈口扩张的占5.6%。伴有宫颈口扩张的子宫收缩是早产的高危因素（52%-70%），而单纯子宫收缩则是低风险因素。预防早产是有益的。我们发现487例单胎早产分娩经治疗后早期新生儿死亡率显著降低。建议对不明原因早产、医源性或选择性早产以及复杂早产进行分类，以用于门诊对照和临床试验。
