Immediate or delayed cord clamping in the preterm birth transition: Is there a trade-off between circulatory stability and sympathoadrenal activation?

利用已建立的早产实验模型，该项目将确定在出生时延迟夹紧脐带是否比立即夹紧脐带能更好地稳定循环，以及这种改善的稳定性是否以不自主神经系统不激活为代价，而不自主神经系统对出生后增强代谢和肺功能至关重要。本研究结果将为优化早产儿分娩策略提供新的基础信息。

Using an established experimental model of preterm birth, this project will determine if delayed clamping of the umbilical cord at birth leads to better stability of the circulation than immediate clamping, and if this improved stability comes at a cost of not activating the involuntary nervous system essential for enhancing metabolic and lung function after birth. The results of this study will provide fundamental new information for optimizing birth delivery strategies in preterm babies.
