Cheng YW, Antibiotics at the time of induced abortion: the case for universal prophylaxis based on a meta-analysis.

A randomized controlled trial. Iliadou AN. Holsteen V, Crowther CA, Art. Improving access to mifepristone for reproductive health indications. A 2013 Cochrane review of limited evidence concluded that among women with incomplete pregnancy loss (ie, incomplete tissue passage), the addition of misoprostol does not clearly result in higher rates of complete evacuation when compared with expectant management (at 7–10 days, success rates were 80–81% versus 52–85%, respectively) 33. Nicholson JM, The risks of waiting for the onset of spontaneous labor are low between 41 and 42 weeks' gestation (e.g., stillbirth rate is just over one per 1,000 births)9; therefore, expectant management should be considered during this period based on patient preference and willingness to undergo antenatal fetal surveillance.

Data Sources: We searched PubMed, the Cochrane database, POEMs, and the National Guideline Clearinghouse using the keywords postterm or postdates pregnancy, and included results between 1990 and May 2014. ABSTRACT: Early pregnancy loss, or loss of an intrauterine pregnancy within the first trimester, is encountered commonly in clinical practice.
From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world. Induction of labour for improving birth outcomes for women at or beyond term. Art. The cause of an isolated spontaneous abortion is usually unknown. Most studies suggest that a larger dose of misoprostol is more effective than a smaller dose, and vaginal or sublingual administration is more effective than oral administration, although the sublingual route is associated with more cases of diarrhea 26.
As a training supplement, Meditec has gathered commonly used obstetrics words for reference to facilitate students’ learning. Neilson JP, 181. So, the above mentioned patient has been pregnant five times, has had three live births, one miscarriage, one medically induced abortion, one set of twins and one other pregnancy that was carried to term and delivered.

A Cochrane review showed that beginning sweeping at term (beyond 38 weeks) reduced the duration of pregnancy and reduced the likelihood that the pregnancy would continue beyond 41 weeks (relative risk = 0.59; 95% CI, 0.46 to 0.74) or 42 weeks (relative risk = 0.28; 95% CI, 0.15 to 0.50).

Treatment of an early pregnancy loss before confirmed diagnosis can have detrimental consequences, including interruption of a normal pregnancy, pregnancy complications, or birth defects 9.

Patient-reported symptoms also should be considered when determining whether complete expulsion has occurred. Approximately 50% of all cases of early pregnancy loss are due to fetal chromosomal abnormalities 5 6. et al. Now assume that she becomes pregnant by whatever means (naturally or following fertility treatment), the same blood pregnancy test would be positive as there is now beta hcg circulating in the blood stream. Ann Intern Med. Diagnosis is by clinical criteria and ultrasonography.

When expectant management is chosen, most experts recommend beginning twice-weekly antenatal surveillance at 41 weeks with biophysical profile or nonstress testing plus amniotic fluid index (modified biophysical profile); induction may be deferred until 42 weeks if this surveillance is reassuring.

Irion O. Based on these studies, the Society of Radiologists in Ultrasound Multispecialty Panel on Early First Trimester Diagnosis of Miscarriage and Exclusion of a Viable Intrauterine Pregnancy created guidelines that are considerably more conservative than past recommendations and also have stricter cutoffs than the studies on which they are based 14 Table 1.

Patients undergoing expectant management may experience moderate-to-heavy bleeding and cramping. Martin JA, A second systematic review confirmed a significant reduction in perinatal mortality in this population, with a number needed to induce of 328 to prevent one perinatal death.20, The fetal morbidity most clearly associated with late-term or postterm gestation is meconium aspiration syndrome,15,21,22 which is more common at 40 and 41 weeks' gestation compared with 39 weeks' gestation.23 Based on high-quality evidence, the risk of meconium aspiration syndrome can be reduced by induction of labor at 41 weeks compared with allowing the pregnancy to continue to 42 weeks or beyond.19,20,24 Decreasing the risk of macrosomia by induction at 41 weeks may also be beneficial.20 In some studies, meconium aspiration syndrome has been associated with perinatal risk of pneumonitis, pneumothorax, low Apgar scores, and need for admission into the neonatal intensive care unit.17 It does not appear that induction reduces these risks, however. They should be given emotional support and, in the case of spontaneous abortions, reassured that their actions were not the cause. Rates of birth, stillbirth, neonatal deaths, and extended perinatal death in 2005 by gestational age. In cases in which an intrauterine gestation cannot be identified with reasonable certainty, serial serum β-hCG measurements and ultrasound examinations may be required before treatment to rule out the possibility of an ectopic pregnancy.

The following recommendations are based primarily on consensus and expert opinion (Level C): Accepted treatment options for early pregnancy loss include expectant management, medical treatment, or surgical evacuation. 13.

Merck & Co., Inc., Kenilworth, NJ, USA is a global healthcare leader working to help the world be well. Spontaneous abortion is noninduced embryonic or fetal death or passage of products of conception before 20 weeks gestation.Threatened abortion is vaginal bleeding without cervical dilation occurring during this time frame and indicating that spontaneous abortion may occur in a woman with a confirmed viable intrauterine pregnancy.
