Human fetal intrapartum oxygen saturation monitoring: agreement between readings from two sensors on the same fetus
Article Abstract:
The agreement of measurements from two identical fetal oxygen sensors may be important in clinical trials for determining oxygen saturation values that call for treatment. Researchers placed two identical Nellcor fetal pulse oximeter sensors on either side of the faces of 12 fetuses during term labor. The average fetal oxygen saturation values of one sensor was 49.2%, while that of the other sensor was 49.9%. The difference of -0.7% translated to a standard deviation of 5.3% from any one sensor. This standard deviation is not clinically significant even though it is statistically significant. Measurements obtained by fetal oxygen sensors cannot be compared to fetal arterial oxygen levels because the latter cannot be reliably obtained during labor. Interinstrument values are more critical.

Intrapartum management of nonreassuring fetal heart rate patterns: A randomized controlled trial of fetal pulse oximetry
Article Abstract:
A study is conducted to test if fetal oximetry in addition to electronic fetal monitoring (CTG) and scalp blood sampling improves the accuracy of fetal assessment and allows safe reduction of operative deliveries and scalp blood sampling performed because of nonreassuring fetal status. The increase in cesarean sections because of dystocia in the study group was a well-documented arrest of labor, but it did not change the total number of operative deliveries in this group.

The effect of intrapartum fetal pulse oximetry, in the presence of a nonreassuring fetal heart rate pattern, on operative delivery rates: A multicenter, randomized, controlled trial (the FOREMOST trial)
Article Abstract:
A study was conducted to compare operative delivery rates for nonreassuring fetal status between 2 groups of laboring women namely those having conventional cardiotocograph monitoring and those having cardiotocograph monitoring plus fetal pulse oximetry. Result showed that the use of fetal pulse oximetry to augment fetal well-being assessment during labor resulted in a statistically significant reduction in the operative intervention for nonreassuring fetal status.
