Abstract
In eight sheep, uterine and umbilical blood flows and oxygen uptakes, the transplacental flow-limited clearance of an inert molecule, pH values, and oxygen pressures, saturations, and capacities in the main placental vessels have been measured during maternal air breathing and oxygen inhalation. The mean +/-SEM percentage changes during oxygen inhalation were +4.6 +/-8.4 for the umbilical flow, +2.8 +/-8.7 for the uterine flow, and +4.6 +/-6.2 for the clearance. None of these changes are statistically significant. Oxygen uptake rose slightly in two cases and remained unchanged in the others. In all cases the oxygen pressures, saturations, and contents rose significantly in the uterine and umbilical vessels with oxygen inhalation.
摘要
在8只绵羊中，测量了母体呼吸空气和吸氧期间的子宫和脐血流量、氧摄取量、惰性分子的经胎盘流量限制清除率、pH值以及主要胎盘血管中的氧分压、饱和度和容量。吸氧期间的平均±标准误百分比变化为：脐血流量为+4.6±8.4，子宫血流量为+2.8±8.7，清除率为+4.6±6.2。这些变化均无统计学意义。2例氧摄取量略有上升，其他病例保持不变。在所有情况下，吸氧后子宫和脐血管中的氧分压、饱和度和含量均显著升高。
