The blood gas and acid-base status of the fetus can be studied, and fetal hypoxia and acidosis can be diagnosed directly. To establish normal ranges of fetal blood gas and acid-base status, we analyzed umbilical venous blood samples obtained by funipuncture from 62 normal fetuses (20-35 weeks). These fetuses were studied because of suspected fetal diseases and were subsequently proved to be normal by the fetal blood examinations. Umbilical vein pH and pO2 decreased whereas pCO2 and bicarbonate increased with gestational age. The umbilical vein base excess did not correlate with gestational duration, but oxygen saturation tended to decrease with gestational age. Twenty hydropic fetuses with Bart hemoglobinopathy were also studied; they were found to be more acidotic, hypoxic, and hypercarbic than normal fetuses. |
