背景资料：胎儿血氧饱和度的知识，作为一种辅助电子胎儿监护，可能与剖宫产率或婴儿的条件在birth.Methods的显着变化：我们随机分配5341初产妇谁是在长期和早期劳动力要么“开放”或“掩蔽”胎儿脉搏血氧饱和度。在开放组中，向临床医生显示胎儿血氧饱和度值。盲法组插入胎氧传感器，计算机记录数值，但数据被隐藏。分娩并发症的一个nonreasonable胎儿心率随机化前记录为后续analysis.Results：有没有显着差异，剖腹产的开放和掩蔽组（26.3%和27.5%，分别为P=0.31）之间的整体利率。两组中与不安全胎心率（分别为7.1%和7.9%; P=0.30）和难产（分别为18.6%和19.2%; P=0.59）相关的剖宫产率相似。在2168名随机分组前检测到不安全胎心率的妇女中也观察到类似的结果。出生时的婴儿的条件并没有显着差异between the two group.Conclusions：知识的胎儿血氧饱和度是不相关的剖宫产率的降低或改善新生儿的状况。（ClinicalTrials.gov编号，NCT 00098709）。
Background: Knowledge of fetal oxygen saturation, as an adjunct to electronic fetal monitoring, may be associated with a significant change in the rate of cesarean deliveries or the infant's condition at birth.Methods: We randomly assigned 5341 nulliparous women who were at term and in early labor to either "open" or "masked" fetal pulse oximetry. In the open group, fetal oxygen saturation values were displayed to the clinician. In the masked group, the fetal oxygen sensor was inserted and the values were recorded by computer, but the data were hidden. Labor complicated by a nonreassuring fetal heart rate before randomization was documented for subsequent analysis.Results: There was no significant difference in the overall rates of cesarean delivery between the open and masked groups (26.3% and 27.5%, respectively; P=0.31). The rates of cesarean delivery associated with the separate indications of a nonreassuring fetal heart rate (7.1% and 7.9%, respectively; P=0.30) and dystocia (18.6% and 19.2%, respectively; P=0.59) were similar between the two groups. Similar findings were observed in the subgroup of 2168 women in whom a nonreassuring fetal heart rate was detected before randomization. The condition of the infants at birth did not differ significantly between the two groups.Conclusions: Knowledge of the fetal oxygen saturation is not associated with a reduction in the rate of cesarean delivery or with improvement in the condition of the newborn.
