本研究的目的是确定成功的头外翻转是否会增加延长分娩或手术分娩的可能性。在1997年1月1日至1998年12月31日期间，妊娠大于或等于37周的正常单胎胎儿成功的头外胎位女性被纳入研究范围。每个病例都匹配分娩时的胎龄（+/- 1周），分娩开始（自然或诱发），既往阴道分娩（是或否），以及入院分娩时宫颈扩张（+1厘米）。检查了产妇人口统计学、产时变量、新生儿结局和分娩途径。统计比较采用学生t检验或费雪精确检验。38例病例和114例对照在产妇年龄、种族、分娩胎龄、出生体重和保险公司方面相似。在硬膜外或催产素使用的频率、产妇生殖道撕裂或分娩时失血方面没有差异。以1分钟和5分钟Apgar评分< 7或新生儿重症监护病房（NICU）入院来评估的新生儿结局在病例和对照组之间没有差异。成功分娩的患者的分娩时间与自然顶点胎儿的分娩时间相似（10.8 +/- 8.9 vs 10.1 +/- 10.1小时，p = 0.4）。手术阴道分娩和剖宫产的频率与对照组无显著差异（3/38 vs 1/114, p = 0.56; 4/38 vs 8/114, p = 0.51）。成功外头位胎儿后的产程和分娩路径与自然胎顶胎儿的妇女没有区别。
The objective of this study is to determine if successful external cephalic version is followed by an increased likelihood of prolonged labor or operative delivery. Women having a successful external cephalic version of a normal singleton fetus greater than or equal to 37 weeks' gestation between January 1, 1997 and December 31, 1998 were included. Each case was matched for gestational age at delivery (+/- 1 week), labor onset (spontaneous or induced), prior vaginal delivery (yes or no), and cervical dilation on admission for delivery(+1 cm) to the next three patients delivering a spontaneously vertex term singleton. Maternal demographics, intrapartum variables, neonatal outcomes, and route of delivery were examined. Statistical comparisons were performed by the Student's t-test or Fisher's exact test. The 38 cases and 114 controls were similar by maternal age, race, gestational age at delivery, birth weight, and insurer. There were no differences in the frequency of epidural or oxytocin use, maternal genital tract lacerations, or blood loss at delivery. Neonatal outcomes, assessed by 1- and 5-min Apgar score < 7, or neonatal intensive care unit (NICU) admission did not differ between cases and controls. The labor length of patients undergoing successful version was similar to that of women laboring with spontaneously vertex fetuses (10.8 +/- 8.9 vs. 10.1 +/- 10.1 hr, p = 0.4). The frequencies of operative vaginal and cesarean delivery in cases did not differ from those of controls (3/38 vs. 1/114, p = 0.56 and 4/38 vs. 8/114, p = 0.51, respectively.) Labor duration and delivery route following successful external cephalic version do not differ from women with spontaneously vertex fetuses.
