脐带结扎的最佳时机一直是一个有争议的话题。虽然产科医师及儿科医师关注的侧重点不同,但仍是大家共同关注的一个问题。产科医师更关注脐带结扎时间对产妇产时出血的风险影响等,儿科医师更关注其对新生儿Apgar评分、新生儿窒息的影响及远期预后。但是,包括美国在内,尽管许多关于新生儿脐带延迟结扎和及早脐带结扎的随机对照试验提示了脐带延迟结扎的好处,但脐带结扎的理想时机尚未建立。为了找到一个 The optimal timing of umbilical cord ligation has been a topic of debate. While obstetricians and pediatricians are focusing on different priorities, they remain a common concern. Obstetricians are more concerned about the impact of umbilical cord ligation time on the risk of obstetric hemorrhage, pediatricians are more concerned about their Apgar score, the impact of neonatal asphyxia and long-term prognosis. However, many randomized controlled trials of delayed ligation of umbilical cord in neonates and early ligation of the umbilical cord, including the United States, have not yet established the ideal timing of ligation of the umbilical cord, suggesting the benefits of delayed ligation of the umbilical cord.
