Umbilical cord milking (UCM) improves blood pressure and urine output, and decreases the need for transfusions in comparison to immediate cord clamping (ICC). The immediate effect of UCM in the first few minutes of life and the impact on neonatal resuscitation has not been described.
Women admitted to a tertiary care center and delivering before 32 weeks gestation were randomized to receive UCM or ICC. A blinded analysis of physiologic data collected on the newborns in the delivery room was performed using a data acquisition system. Heart rate (HR), SpO2, mean airway pressure (MAP), and FiO2 in the delivery room were compared between infants receiving UCM and infants with ICC.
41 of 60 neonates who were enrolled and randomized had data from analog tracings at birth. 20 of these infants received UCM and 21 had ICC. Infants receiving UCM had higher heart rates and higher SpO2 over the first 5 minutes of life, were exposed to less FiO2 over the first 10 minutes of life than infants with ICC.
UCM when compared to ICC had decreased need for support immediately following delivery, and in situations where resuscitation interventions were needed immediately, UCM has the advantage of being completed in a very short time to improve stability following delivery.

与即刻脐带结扎(ICC)相比,脐带挤血(UCM)可改善血压和尿量,并减少输血需求。UCM在出生后最初几分钟的即时效果以及对新生儿复苏的影响尚未见描述。
入住三级护理中心且孕周小于32周分娩的妇女被随机分组,分别接受UCM或ICC。使用数据采集系统对产房内新生儿收集的生理数据进行盲法分析。比较接受UCM的婴儿和接受ICC的婴儿在产房内的心率(HR)、血氧饱和度(SpO2)、平均气道压(MAP)和吸入氧浓度(FiO2)。
60例入选并随机分组的新生儿中,41例有出生时模拟记录的数据。其中20例婴儿接受UCM,21例接受ICC。接受UCM的婴儿在出生后最初5分钟内心率和SpO2较高,在出生后最初10分钟内比接受ICC的婴儿接触的FiO2更少。
与ICC相比,UCM在分娩后立即对支持的需求减少,并且在需要立即进行复苏干预的情况下,UCM具有能在极短时间内完成以改善分娩后稳定性的优势。
