Lato K, et al. - Researchers here aimed at assessing the impact of hypotension due to spinal anesthesia in primary caesarean sections on fetal blood circulation. In situations with decreased uteroplacental blood flow, healthy fetuses seemed to compensate well, due to maternal hypotension measured by means of resistant index (RI) changes in the fetal umbilical and middle cerebral artery. Finding thereby raises the question if growth-restricted and/or preterm fetuses are able to compensate similarly or if general anesthesia would be a method of choice.
