Fetal distress after artificial rupture of membranes

Glycogenolytic Activity in the Liver of the Human Foetus

“…The specimen was imme diately frozen in liquid nitrogen, and the time interval from opening the uterus to the freezing (% -3 min) was noted (the uterine blood flow is reduced by rupture of the foetal membranes [BrotAnek and H odr, 1968]; therefore in the present study this intervention was considered to start the foetal asphyxia). In 21 cases, the umbilical cord was then clamped and divided, and the foetus was left in the maternal abdomen to ensure unchanged external thermal conditions.…”

Review article

“…Much more important to us is the fact that within a period of 30 minutes after amniotomy one can find a much higher amount of alarm dips than dips I from which fact one might conclude that the amniotomy could be a dangeroüs factor to the fetus. BROTANEK [7] cönfirmed these fmdings by proving that there is a decrease of blood flow within 30 to 40 minutes after amniotomy that leads to a transient hypoxemia. The effect of this hypoxemia we could demonstrate for a period of 9 to 12 minutes.…”

Fetal heart rate patterns in labors with intact and with ruptured membranes

“…retardation was significantly lower in children Finally, BROTANEK et al [4,5] have shown that born from labors in which membranes were not amniotomy produced a long lasting reduction of uterine blood flow. All these efFects should increase the incidence of type II dips in FHR.…”
