A controlled prospective study of the differential effects of intrapartum fetal monitoring on mothers and infants has been conducted at Denver General Hospital, Denver, Colorado. A total of 690 high-risk obstetric patients in labor were randomly assigned to one of three monitoring groups--auscultation, electronic fetal monitoring alone, or electronic monitoring with the option to scalp sample. There were no differences in immediate infant outcomes in any measured category (Apgar scores, cord blood gases, neonatal death, neonatal morbidity, nursery course) among the three groups. There were no differences in rates of infant or maternal infections. The cesarean section rate was markedly increased in the electronically monitored groups, especially in the electronically monitored alone (18%) as compared with the auscultated (6%) (P less than 0.005). In this controlled trial electronic monitoring did not improve neonatal outcomes and the mothers were at increased risk of cesarean section.
科罗拉多州丹佛市的丹佛总医院开展了一项关于分娩期胎儿监护对母婴不同影响的前瞻性对照研究。共有690名高危产科分娩患者被随机分配到三个监护组之一——听诊组、单纯电子胎儿监护组或可选择头皮采样的电子监护组。三组在任何测量类别（阿氏评分、脐血气、新生儿死亡、新生儿发病率、新生儿病程）中的即时婴儿结局均无差异。婴儿或产妇感染率也无差异。电子监护组的剖宫产率显著升高，尤其是单纯电子监护组（18%），相比听诊组（6%）（P<0.005）。在这项对照试验中，电子监护并未改善新生儿结局，且母亲剖宫产风险增加。
