Intrapartum fetal pulse oximetry: past, present, and future

Article Abstract:

Fetal pulse oximetry may eventually be a promising means of monitoring fetal well-being during labor. Pulse oximetry uses light to noninvasively determine the oxygen content of the blood. It is in standard use in children and adults. However, monitoring the fetus during labor presents considerable technical difficulties. In addition, a normal range of values must be established and correlations made between oxygen levels and fetal condition. Research is ongoing in all three areas. If fetal pulse oximetry proves to be safe, effective, and cost effective, it may provide a valuable new tool in obstetrics.

Prospective evaluation of the antenatal incidence and postnatal significance of the fetal echogenic cardiac focus: a case-control study

Article Abstract:

Finding echogenic cardiac foci during second trimester ultrasound imaging does not always indicate heart complications. Cardiac echogenic foci could indicate a tumor or dysfunction of the heart muscle. Of 506 fetuses routinely evaluated by ultrasound imaging in the middle trimester, 5% had echogenic foci. All had ultrasonographic evaluation within 20 weeks after birth. One newborn had a minor heart malformation unrelated to the ultrasound imaging finding. Therefore, following up the finding of echogenic cardiac foci with heart evaluation studies after birth does not appear warranted.

Very advanced maternal age: pregnancy after age 45

Article Abstract:

Pregnant women older than 45 years of age may have an uncomplicated pregnancy and delivery. They may, however, be at increased risk for cesarean delivery and their infants may be at greater risk for genetic birth defects. Researchers identified 79 mothers 45 years of age and older who delivered between 1985 and 1994. Forty-seven percent of these women had complications during pregnancy including 10.1% with preeclampsia and 12.7% with gestational diabetes. The cesarean delivery rate in this population was 31.7%. Ten percent of the infants had genetic abnormalities.
