Moreover, the presence of meconium, long associated with nonreassuring fetal status
, was found in one study to have no association with CP.
C-sections were performed for various reasons: three for nonreassuring fetal status, three for failure to progress, one for malpresentation, and one as an elective repeat C-section.
Deliver the patient in cases of maternal instability or nonreassuring fetal status; labor or rupture of membranes; or gestational age greater than 34 weeks.
Obstetric interventions were defined as either a repeat cesarean section or an assisted vaginal delivery both of which were performed for indications of nonreassuring fetal status
In the multicenter trial, which involved 1,010 pregnancies, use of oximetry dropped the rate of cesarean sections because of a nonreassuring fetal status
from 10.2% in control deliveries to 4.5% when oximetry was used.
"The addition of fetal oximetry monitoring to conventional fetal heart rate monitoring improves the accuracy of fetal assessment and permits the safe reduction in the number of cesarean sections for nonreassuring fetal status without causing injury to mother or child," said Dr.
The device, known as the Nellcor-400 Fetal Oxygen Saturation Monitoring System, was associated with a reduced rate of cesarean deliveries for nonreassuring fetal status in a pivotal trial of more than 1,000 women.
Obstetric interventions were defined as either a repeat cesarean section or an assisted vaginal delivery, both of which were performed for indications of nonreassuring fetal status
The paper's authors suggest that medical factors other than failure to progress, such as nonreassuring fetal status
, macrosomia, or preeclampsia, may have been the reason for the delivery decision.
