Delay in cord clamping up to 30 to 40 seconds is feasible and should be practiced in preterm and term infants born by cesarean section. In term infants, this maneuver may decrease iron deficiency anemia at 6 months of age. Premature infants may have a higher blood volume and hematocrit initially requiring fewer transfusions. They also have a decreased incidence of intraventricular hemorrhage. The effect of compounding factors, such as maternal blood pressure, uterine contraction, medications, bleeding, and their effects on the infant's immediate and long-term outcome are unclear.
延迟脐带结扎30至40秒是可行的，对于剖宫产出生的早产和足月婴儿都应采用。对于足月婴儿，这种操作可能会降低6个月大时缺铁性贫血的发生率。早产儿最初可能血容量更高、血细胞比容更高，从而需要较少的输血。他们的脑室内出血发生率也较低。诸如产妇血压、子宫收缩、药物、出血等复合因素的影响以及它们对婴儿近期和远期结局的影响尚不清楚。
