Mares and fetuses with indwelling catheters in the umbilical and uterine vessels have been used to monitor transplacental blood gas tensions, pH, O2 affinities and the concentration of various metabolites in fetal and maternal blood during late gestation. Measurements of umbilical and uterine blood flows and arterio-venous differences enabled the uptake of O2 and glucose by the fetus and the uterus to be estimated. The present findings are compared with those from other species in comparable conditions.
在妊娠后期，已对脐血管和子宫血管中留置导管的母马和胎儿进行监测，以测定经胎盘的血气张力、pH值、氧亲和力以及胎儿和母体血液中各种代谢物的浓度。通过测量脐血流量和子宫血流量以及动静脉差异，能够估算胎儿和子宫对氧气和葡萄糖的摄取量。将目前的研究结果与其他物种在类似条件下的结果进行了比较。
