Daily antepartum nursing contact and ambulatory uterine activity monitoring have been used for the early detection of preterm labor. However, it may be difficult to separate true labor from false labor. In this study, the uterine activity records of 110 women at risk for preterm birth with excessive contraction frequencies were evaluated by blinded reviewers. Maternal symptomatology and uterine activity characteristics such as low-amplitude high-frequency contractility, contraction amplitude, contraction duration, contraction interval, and contraction rhythmicity were assessed for their ability to differentiate true from threatened preterm labor. Neither maternal symptomatology nor any uterine activity characteristic other than contraction frequency could differentiate true from threatened preterm labor. Antepartum uterine activity monitoring should continue to rely on contraction frequency to identify the woman at risk for premature labor.
每日产前护理接触和动态子宫活动监测已被用于早产的早期检测。然而，将真正的分娩与假分娩区分开来可能很困难。在本研究中，由不知情的评审人员对110名有早产风险且宫缩频率过高的女性的子宫活动记录进行了评估。评估了母亲的症状以及子宫活动特征，如低振幅高频收缩性、宫缩幅度、宫缩持续时间、宫缩间隔和宫缩节律性，以确定它们区分真正早产与先兆早产的能力。除了宫缩频率外，母亲的症状和任何子宫活动特征都无法区分真正早产与先兆早产。产前子宫活动监测应继续依靠宫缩频率来识别有早产风险的女性。
