Perinatal heart rate variability and circulatory adaptation in association with normal labor and after elective cesarean section.
Heart rate variability and basal hemodynamic parameters were studied in connection with 20 normal deliveries and after 16 elective cesarean sections. Eight of the cesarean sections were performed with the use of maternal barbiturate anesthesia and eight with the use of epidural blockade. The interval index describing the long-term variability and the differential index describing the short-term variability of the heart rate were measured continuously from 10-minute samples of a direct fetal electrocardiogram and a neonatal electrocardiogram of the infants by a microprocessor-based system. ⋯ Newborn infants after elective cesarean section had significantly lower diastolic blood pressures than infants delivered normally, but there was no difference in the diastolic blood pressures between the two cesarean section subgroups. The infants delivered vaginally had lower heel temperatures than those delivered abdominally. According to the present study, the neonatal circulatory adaptation after elective cesarean section is different from that after normal delivery; however, the neonatal hemodynamics after cesarean section with epidural blockade more closely resemble the situation after normal labor.

Case ReportsMarfan's syndrome: acute aortic dissection during labor, resulting in fetal distress and cesarean section, followed by successful surgical repair.
A unique case of Marfan's syndrome is presented in which the diagnosis was first established during early labor when the patient presented with chest pain, hypotension, and fetal distress as the earliest symptoms and signs. Prompt diagnosis in combination with correct medical and surgical therapy resulted in the survival of both the mother and infant.
