Our purpose was to evaluate the impact of home uterine activity monitoring on pregnancy outcomes among women at high risk for preterm labor and delivery.
Women at high risk for preterm labor at three centers were randomly assigned to receive high-risk prenatal care alone (not monitored) or to receive the same care with twice-daily home uterine activity monitoring without increased nursing support (monitored). There were 339 women with singleton gestations randomized with caregivers blinded to group assignment. The two groups were medically and demographically similar at entry into the study.
Women in the monitored group had prolonged pregnancy survival (p = 0.02) and were less likely to experience a preterm delivery (relative risk 0.59; p = 0.04). Infants born to monitored women with singleton gestations were less likely to be of low birth weight (< 2500 gm; relative risk 0.47, p = 0.003), and were less likely to be admitted to a neonatal intensive care unit (relative risk 0.5, p = 0.01).
These data show, among women with singleton gestations at high risk for preterm delivery, that the use of home uterine activity monitoring alone, without additional intensive nursing care, results in improved pregnancy outcomes, including prolonged gestation, decreased risk for preterm delivery, larger-birth-weight infants, and a decreased need for neonatal intensive care.
我们的目的是评估家庭子宫活动监测对早产和分娩高危女性妊娠结局的影响。
三个中心的早产高危女性被随机分配，一组仅接受高危产前护理（不进行监测），另一组接受相同护理并每天进行两次家庭子宫活动监测且不增加护理支持（进行监测）。共有339名单胎妊娠女性被随机分组，护理人员对分组情况不知情。两组在进入研究时在医学和人口统计学方面相似。
进行监测的组妊娠持续时间延长（p = 0.02），早产的可能性较小（相对风险0.59；p = 0.04）。单胎妊娠且接受监测的女性所生婴儿出生体重低（<2500克）的可能性较小（相对风险0.47，p = 0.003），入住新生儿重症监护病房的可能性也较小（相对风险0.5，p = 0.01）。
这些数据表明，在单胎妊娠且早产高危的女性中，仅使用家庭子宫活动监测，无需额外的强化护理，就能改善妊娠结局，包括延长妊娠期、降低早产风险、增加出生体重以及减少对新生儿重症监护的需求。
