Hydration Hydration should constitute an integral part of intrauterine resuscitation unless there is a contraindication for infusing reasonable amounts of 180 - 200 mL of fluid per hour. In conditions where hypotension is expected e.g. epidural analgesia, maternal bleeding, etc it is important to hydrate the women well to prevent FHR changes. Inadequate uteroplacental perfusion or umbilico-placental perfusion in some cases is responsible for fetal hypoxia and acidosis. Thus hydration is an important component of labor management
