The plasma catecholamine surge at birth: its role in determining variations in brain function.

出生是一个独特的过程。 我们的长期目标是更好地了解出生的生理学，特别是了解调节机制如何在出生期间保护大脑。 在正常分娩过程中，新生儿会随着母亲子宫的每次收缩而经历氧气减少（缺氧）。 此外，与第一产程相比，第二产程中新生儿的血氧含量有所下降。 然而，对于在正常分娩期间或在更严重的缺氧（例如在很长的分娩过程中）期间可能保护新生儿大脑免受缺氧的机制知之甚少。

Birth is a unique process. Our long term goal is to better understand the physiology of birth - in particular, to understand how regulatory mechanisms protect the brain during birth. During a normal birth, the newborn experiences a decrease in oxygen (hypoxia) with each contraction of the mother's uterus. In addition there is a fall in the newborn's blood oxygen during 2nd stage labor compared to 1st. However little is known about mechanisms that might protect the newborn brain from hypoxia during normal birth or during more severe hypoxia such as in a very long labor.
