ReviewTocolytic treatment for the management of preterm labor: a review of the evidence.
Preterm labor is often a prelude to early births and the significant attendant burden of infant morbidity and mortality. Treatment consists of bedrest, hydration, pharmacologic interventions, and combinations of these. We systematically reviewed the effectiveness of tocolytics to stop uterine contractions (first-line therapy) or maintain quiescence (maintenance therapy). Our objective was to evaluate the evidence on the benefits and harms of five classes of tocolytic therapy for treating uterine contractions related to preterm labor--beta-mimetics, calcium channel blockers, magnesium, nonsteroidal anti-inflammatory agents, and ethanol. ⋯ Management of uterine contractions with first-line tocolytic therapy can prolong gestation. Among the tocolytics, however, beta-mimetics appear not to be better than other drugs and pose significant potential harms for mothers; ethanol remains an inappropriate therapy. Continued maintenance tocolytic therapy has little or no value.

Is the incidence of fetal-to-maternal hemorrhage increased in patients with third-trimester bleeding?
If a pregnancy is complicated by third-trimester bleeding, is there a higher risk of fetal-to-maternal hemorrhage that might necessitate the administration of additional anti-D immune globulin to prevent alloimmunization in the patient who is Rh D-negative? The study objective was to analyze prospectively the incidence of fetal-to-maternal hemorrhage in pregnancies that were complicated by third trimester bleeding compared with three control groups. ⋯ The incidence of fetal-to-maternal hemorrhage does not appear to be increased in pregnancies that are complicated by third-trimester bleeding when compared to noncomplicated control subjects or to other obstetrically complicated pregnancies. This information would suggest that the routine administration of additional anti-D immune globulin (beyond the current recommended protocol) to women who are Rh D-negative whose pregnancies are complicated by third-trimester bleeding is not indicated.

Subsequent pregnancy outcome in women with a history of HELLP syndrome at < or = 28 weeks of gestation.
The purpose of this study was to describe subsequent pregnancy outcome in women with a history of hemolysis, elevated liver enzymes, and low platelet count syndrome for which delivery occurred at < or = 28 weeks of gestation during the index pregnancy. ⋯ Patients with a history of hemolysis, elevated liver enzymes, and low platelet count syndrome at < or = 28 weeks of gestation during the index pregnancy are at increased risk for obstetric complications in subsequent pregnancies. Overall, however, the rate of recurrent hemolysis, elevated liver enzymes, and low platelet count syndrome is only 6%.

Comparative StudyCesarean delivery on demand: what will it cost?
The purpose of this study was to estimate the cost differences between elective cesarean delivery and the alternative of attempted vaginal delivery and to assess the economic impact of cesarean delivery on demand. ⋯ The adoption of a policy of cesarean delivery on demand should have little impact on the overall cost of obstetric care.

Randomized Controlled Trial Comparative Study Clinical TrialScreening for fetal well-being in a high-risk pregnant population comparing the nonstress test with umbilical artery Doppler velocimetry: a randomized controlled clinical trial.
The purpose of this study was to evaluate the ability of two different modes of antepartum fetal testing to screen for the presence of peripartum morbidity, as measured by the cesarean delivery rate for fetal distress in labor. ⋯ Umbilical artery Doppler as a screening test for fetal well-being in a high-risk population was associated with a decreased incidence of cesarean delivery for fetal distress compared to the nonstress testing, with no increase in neonatal morbidity.
