Fetal monitoring techniques.

It is seen that there are several possible techniques for monitoring the fetus during labor. In addition to those described above, one can take microblood samples from the fetus and analyze for blood gases and pH. The latter is usually the only parameter measured and often is helpful in assessing the fetus. Yet even with spot checks of this chemical determination added to the monitored data, the overall value of fetal monitoring in definitively diagnosing the onset of significant fetal distress must be questioned. Further work and new monitoring techniques and parameters are clearly needed to improve the care of the high risk mother and fetus during labor and delivery.
