A comparison of visual and automated methods of analyzing fetal heart rate tests

Article Abstract:

A computerized method may be just as effective as visual analysis in evaluating the nonstress test (NST). The NST is a standard test that assesses different aspects of fetal heart rate. A study compared the effectiveness of a computerized analysis using the Oxford Sonicaid System 8000 software package to that of visual analysis. The NSTs of 575 women with a high-risk pregnancy were evaluated using both methods. The System 8000 was as accurate as visual analysis in evaluating the NSTs. Further tests or treatments would have been requested for 9% of the patients based on the System 8000 analysis, compared with 49% based on visual analysis. One major problem with visual analysis of NSTs is a high rate of false-positives.

Perinatal ultrasonography and magnetic resonance imaging findings in congenital hydrocephalus associated with fetal intraventricular hemorrhage

Article Abstract:

It appears that some infants born with an abnormal fluid accumulation in their brain may have experienced areas of internal brain bleeding before birth. Magnetic resonance imaging (MRI) scans were used to date and track areas of internal brain bleeding in three infants born with hydrocephaly. MRI scans confirmed that the internal brain bleeding occurred before birth. Areas of the brain surrounding the lesions were enlarged with evidence of tissue wasting, incomplete thalamus development, and cyst formation. Evidence suggested that the lesions developed after a period of oxygen deprivation.

Fetal loss rate associated with cordocentesis at midgestation

Article Abstract:

Cordocentesis can slightly increase the risk of miscarriage, according to a study of 2,040 women. Cordocentesis is used to get blood samples from the fetal umbilical cord for prenatal diagnostic purposes.
