Admission cardiotocography (CTG) was introduced as a screening test for fetal distress in labor in the late 1980s. No systematic assessments of the test were performed before it was taken into widespread use. A screening test is meant to identify individuals with an increased risk for a disease or condition before symptoms occur, to prevent and reduce morbidity or mortality. A screening test should be evaluated according to its effectiveness, prognostic values and reliability. A careful review of the research literature states that routine use of the admission CTG in low-risk women increases the incidence of minor obstetric interventions, may increase the incidence of cesarean sections, but has no impact on other important outcomes. The prognostic values are poor, and the reliability varies from good to poor. There is no evidence showing that the admission CTG is beneficial, and the test should not be offered to low-risk women.
入院胎心监护（CTG）于 20 世纪 80 年代末作为一种产前胎儿窘迫的筛查试验引入。在广泛应用之前，没有对该试验进行系统评估。筛查试验旨在在出现症状之前识别出患有疾病或病症风险增加的个体，以预防和减少发病率或死亡率。筛查试验应根据其有效性、预后价值和可靠性进行评估。对研究文献的仔细审查表明，在低危女性中常规使用入院 CTG 会增加轻微产科干预的发生率，可能会增加剖宫产的发生率，但对其他重要结局没有影响。预后价值较差，可靠性从好到差不等。没有证据表明入院 CTG 有益，因此不应向低危女性提供该检查。
