A comparative study of labor induced by oral prostaglandin E2 and buccal tablets of demoxytocin.

A comparative study of the efficacy of oral prostaglandin E2 and buccal tablets of demoxytocin for induction of labor in overdue pregnancies was made in groups of randomly selected patients. Labor was successfully induced in 95.7% of the women in the prostaglandin group and 92.1% of the women in the demoxytocin group. Although the operative delivery rate was low in both groups, it was significantly higher for the demoxytocin group. A low rate of perinatal distress was recorded and there were no serious side effects in either group. The time from start of induction until delivery, as well as the time from amniotomy until delivery, were compared for primiparae and multiparae separately. No significant differences were found. The blood loss during the third stage of labor was lower in the prostaglandin group. We find oral induction of labor in overdue pregnancies effective, safe and convenient.

High hemoglobin levels during pregnancy and fetal risk.

In a series of 24 apparently uncomplicated pregnancies with small-for-dates newborn at or below the tenth percentile, 15 women had hemoglobin (Hb) levels 2 SD above the mean value of normal distribution in late pregnancy. Among these 15 was the only case with intrauterine death of unknown cause. In a series of 15 cases intrauterine fetal death of unknown cause, before start of labor 10 had Hb levels 2 SD above the mean, while in a series of 16 cases of late abortion where the fetus was alive until labor started, only one had a Hb level 2 SD above the mean. In three cases with serial Hb estimations, the levels were 2 SD above the mean one week or more before intrauterine fetal death. Two of these cases also had been observed during a successful pregnancy in which the Hb levels were within normal limits. It is concluded that high Hb levels during pregnancy may indicate a fetus at risk. High viscosity of the mother's blood may impede the uteroplacental circulation, casing placental infarction, growth retardation and ultimately fetal death.
