Bacterial infections are a major cause of preterm labor, according to the New England Journal of Medicine. An infection in the uterus can cause the uterus to contract, which in turn may cause the amniotic sac to break early. In cases of PPROM that are not caused by infection, there is a high risk of subsequent infection for both mom and baby. Common causes of infection that result in preterm labor include bacterial vaginosis, urinary tract infection, group B streptococcus infection, and sexually transmitted diseases.

In cases of preterm labor where the birth is suspected to take place within one to seven days, two corticosteroid injections such as betamethasone or dexamethasone are given to the mother 24 hours apart. Corticosteroids have also been proven to reduce the risk of bleeding in the brain, intestinal theu, and death. Fetuses typically begin to produce surfactant on their own around 33 to 34 weeks, so the benefits of corticosteroid injections are not as significant after 34 weeks.

Timing the injections is important. If more than seven days pass between the injections and delivery, the effectiveness is decreased. Inthe National Institutes of Health reaffirmed its decision not to endorse repeated cycles of corticosteroids due to potential side effects that can include a lower birth weight and decreased brain development.

It works by blocking the calcium that is needed for the smooth muscle tissue of the uterus to contract. If labor is successfully stopped, a doctor may prescribe nifedipine for at-home use until the pregnancy reaches a less-risky stage such as 34 weeks, or up to 37 weeks.

Baha M. Sibai of the University of Cincinnati College of Medicine wrote that antihypertensive drugs like nifedipine may hide the existence of preeclampsia. Watch for symptoms during the time you are taking nifedipine and watch for symptoms of preeclampsia up until until six weeks after delivery as all women should.

It prevents the production of prostaglandins, which cause contractions. Indomethacin is used to slow contractions for 24 to 48 hours to allow time to administer corticosteroid injections and move the mother to a hospital with a neonatal intensive care unit NICUif necessary.

Indomethacin can be used when beta-sympathetic medications such as terbutaline and ritodrine fail to stop contractions, or when there may be an increased risk of side effects from beta-sympathetics due to heart disease, lung disease or diabetes. Terbutaline relaxes the smooth muscles of the uterus to slow contractions. On February 17,the FDA released a safety announcement that clinicians should not use injectable lbor to prevent preterm labor or treat it beyond 48 to 72 hours because of the risk for maternal heart problems and death.

Also, oral terbutaline should not be used for the prevention or any treatment of preterm labor because it shares the same safety risks as the injectable ztop and has not proven to be what is google play movies tv. The FDA has determined that the cardiovascular risks outweigh any potential benefit to pregnant women receiving terbutaline by injection or by infusion pump on a prolonged basis, or any length of treatment with the oral tablet version of the drug.

The FDA statement acknowledges that there are serious situations where a healthcare professional may decide that the short-term use of injectable terbutaline may benefit a pregnant woman, but stated that such treatment should not extend beyond 48 to 72 hours.
