The pharmacokinetics of certain drugs were studied in the following patient groups: in women in stage III of pregnancy, in women in labor, and in non-pregnant women as a control group. In late gravidity several parameters of distribution and elimination change. Nevertheless, it is not necessary to modify the usual ...
Takahashi K - - 1982
Our clinical experience contradicts the traditional view that in the great majority of nulliparas with cephalic presentation the fetal heat is engaged 1-2 weeks prior to onset of labor. In 75.4% of the 175 cases fetal head was not engaged in early labor. No significant statistical difference between the unengaged-head ...
Weber T - - 1982
Continuous monitoring of the fetal scalp tissue pH (tpH) was performed in 96 consecutive cases. Of these 96, 72 (75%) had acceptable pH tracings which were used for the management of labor (series II). These 72 patients were compared with 72 patients from an earlier series (series I) of tpH ...
Fuchs A R - - 1981
In the present study we have investigated the effect of oxytocin on the production of prostaglandins E and F (PGE and PGF) by human decidua, amnion, and myometrium in vitro. We found that oxytocin causes a significant increase in the production of both PGE and PGF in the decidua and ...
Shepherd J H - - 1981
The results of 1000 consecutive unselected cases of induction of labor for medical or obstetric reasons using prostaglandin E2 suppositories are presented. The overall rate of failed induction resulting in a cesarean section in those patients with an unfavorable cervix has fallen from 42 to 2.5%. Only 27% of the ...
MacKenzie I Z - - 1981
The outcome of labor induced by use of a glyceride-based vaginal suppository of prostaglandin E2 (PGE2) inserted 3 hours before amniotomy, when the cervix is favorable, has been assessed. Using 5 mg PGE2 for primigravidas and 2.5 mg for multigravidas, 63% of the former and 81% of the latter established ...
Kundu N - - 1981
It has been reported that determinations of maternal serum unconjugated estriol (E3) and estetrol (E4) concentrations provide clinicians with more or less identical information on fetal status. If this is true, then theoretically the levels of E3 should be equally correlated with those of E4 in all conditions of pregnancy. ...
Ko H H - - 1981
The cytosol and nuclear fractions were prepared from 32 pieces of myometrium obtained from 20 elective cesarean sections (regarded as typical of quiescent pregnancy (P)) and 12 emergency cesareans (performed after labor had started and therefore taken as typical of labor (L)). The nuclear fraction was purified by standard procedures. ...

Kauppila A - - 1980
A shift in progesterone-to-estradiol balance to estradiol dominance is assumed to be a prerequisite for regular uterine contractions. To antagonize this effect in premature labor 24 consecutive women were treated with intravenous cortisol for 3 days and with weekly intramuscular injections of 17 alpha-hydroxyprogesterone caproate (17 OHP-C). Twenty-four similar patients ...
Hauth J C - - 1980
The perinatal mortality and morbidity of 185 post-term pregnancies managed by weekly trial inductions starting at 42 weeks' gestation were compared to those of 119 post-term pregnancies with spontaneous labor before a trial induction was accomplished. One stillbirth occurred in the spontaneous labor group and one in the induced group. ...
