Continuous transcutaneous PO2 monitoring has yielded some interesting information about the relationships of fetal oxygenation and the fetal heart rate. Notwithstanding the factors that may adversely affect the results obtained by this technique, further insights regarding fetal oxygenation may be gained. Ultimately, the clinical application of this instrument in high-risk situations is possible, yielding more information about the fetus during labor. Fetal scalp blood sampling, performed meticulously, will provide accurate blood pH values and should be employed when a differentiation between fetal stress and distress must be made. Other means of obtaining information about fetal acid-base balance are being developed and may become important tools in selected instances. |
