Human chorion contains steroid sulfohydrolase activity and synthesizes free estrogens from estrone sulfate (E1S). We hypothesized that the free estrogen thus formed may influence the contractility of the adjacent myometrium in late pregnancy. In this study we measured the abilities of various steroids and steroid conjugates to influence the hydrolysis ...
Blakemore K J - - 1988
The obstetric benefits and dangers of using oxytocin to promote uterine activity have long been appreciated. The induction of labor should be undertaken when the positive reasons for delivery outweigh the risks of allowing the pregnancy to continue. Over the years, recognition of the pharmacokinetics of oxytocin has led to ...
Nageotte M P - - 1988
To assess uterine activity before labor in patients delivering preterm, at term, and postterm, the maximum spontaneous contraction frequency per 10-minute window during the initial portion of antepartum fetal heart rate monitoring was analyzed. Patients with multiple gestation, third trimester bleeding, polyhydramnios, or premature rupture of membranes and those already ...

Epileptic seizures during labor are seen rarely. A patient in labor had a 70-minute tonic-clonic convulsion. Maternal acid-base status and oxygenation remained normal. Fetal monitoring showed no evidence of distress. This case suggests that fetal bradycardia during maternal seizures is due to hypoxia and acidosis, not to other factors.
Chestnut D H - - 1987
A randomized double-blind study evaluated the analgesic efficacy and influence of maintaining a continuous epidural infusion of 0.75% lidocaine during the second stage of labor in nulliparous women. When the cervix was 8 cm or more dilated, unidentified study solution was substituted for the known 0.75% lidocaine solution and continued ...
Rothman B K - - 1987
This paper suggests that the key unifying concept in the development and application of new reproduction technology has been the increasing commodification of life--treating people and parts of people as marketable commodities. This commodification process is made most dramatically clear in (1) prenatal diagnosis, in which the fetus is treated ...
Nager C W - - 1987
Delivery with an unfavorable cervix using oxytocin is frequently unsuccessful. Used widely in Europe and increasingly in this country, locally applied prostaglandin E2 appears to improve labor induction. The present study prospectively evaluated the efficacy and safety of a prostaglandin gel (0.5 mg) placed intracervically. The use of the gel, ...
