Intrapartum fetal atrial bigeminy - diagnostic and therapeutic role of the fetal scalp stimulation test
Article Abstract:
A noninvasive fetal scalp stimulation test during labor may detect a normal oxygen balance in blood in the absence of a normal heartbeat, and may prevent unnecessary cesarean deliveries for fetal distress. Researchers performed a fetal scalp stimulation test during labor on a 38-week-old fetus with an irregular heart rate caused by premature atrial contractions. The irregular contractions caused the heart rate to slow to 80 beats per minute during the hour-long labor stage of pushing. Labor was allowed to continue since the umbilical cord was not found to be compressed or protruding, and blood pressure was normal. A healthy baby girl was delivered vaginally. The premature atrial contractions had ended by her second day of life. Fetal scalp stimulation estimates oxygen delivery by detecting a biophysical response to stress.

A comparison of visual analyses of intrapartum fetal heart rate tracings according to the new National Institute of Child Health and Human Development guidelines with computer analyses by an automated fetal heart rate monitoring system
Article Abstract:
Computerized analysis of tracings from a fetal heart monitor may be more accurate than doctors and nurses who analyze the tracings using guidelines developed by the National Institute of Child Health and Human Development. This was the conclusion of researchers who compared results generated by Hewlett-Packard TraceVue, two doctors, one nurse, and one nurse-midwife.

Oxygen-dependent regulation of membrane potential and vascular tone of human umbilical vein
Article Abstract:
Oxygen affects the vascular tone of umbilical veins and the endothelium appears to be necessary for this response. The veins maintain their tone even during conditions of low oxygen.
