A detailed analysis of the antenatal cardiotocographs (CTGs) in 57 patients with suspected fetal growth retardation is presented. Four traces were normal and 53 were 'non-reactive'. 'Non-reactive' traces can be sub-divided into three categories, which, in order of severity are, 'suspect', 'flat' and 'ominous'. When compared with the 'suspect' group, perinatal mortality was significantly increased and the Apgar scores at one and five minutes significantly decreased in the 'flat' and 'ominous' groups. The presence of fetal distress in labour was significantly higher in the 'flat' group as compared with the 'suspect' group. Intrauterine deaths occurred only in the 'ominous' group. With experience, ten patients later in the series with 'ominous' patterns were delivered within 24 hours of the detection of such and nine infants survived. At follow-up between 6 and 34 months after birth, psychomotor development was normal in 47 of the 49 surviving infants.
本文对57例疑似胎儿生长受限患者的产前胎心监护图（CTG）进行了详细分析。其中4例轨迹正常，53例为“无反应型”。“无反应型”轨迹可细分为三类，按严重程度依次为“可疑型”、“平坦型”和“不祥型”。与“可疑型”组相比，“平坦型”和“不祥型”组的围产期死亡率显著增加，1分钟和5分钟时的阿氏评分显著降低。与“可疑型”组相比，“平坦型”组产时胎儿窘迫的发生率显著更高。宫内死亡仅发生在“不祥型”组。随着经验的积累，该系列后期出现“不祥型”模式的10例患者在检测到这种模式后的24小时内分娩，9名婴儿存活。在出生后6至34个月的随访中，49名存活婴儿中有47名精神运动发育正常。
