The womb is the best place to grow your baby. However, about 10 percent of women in the United States will experience premature labor and many of these women will give birth to premature infants. The average pregnancy lasts about 40 weeks. The definition of a term pregnancy is a pregnancy at 37 weeks. Infants born as early as 22 weeks are surviving with appropriate medical care and hospitalization.

ABSTRACT: Corticosteroid administration before anticipated preterm birth is one of the most important antenatal therapies available to improve newborn pregnajcy. Rescue course corticosteroids could be provided as early as 7 days from the prior dose, if indicated by the clinical scenario.
Continued surveillance of long-term outcomes after in utero corticosteroid exposure pregnanyc be supported. Quality improvement strategies to optimize appropriate and timely antenatal corticosteroid administration are encouraged. This Committee Opinion was developed to help guide the timing and frequency of pregnnancy administration under various clinical contexts before preterm birth.
Corticosteroid administration before anticipated preterm birth is one of the most important antenatal therapies available to improve BBmz outcomes pregancy.
The administration of antenatal corticosteroids to the woman who is at risk of imminent preterm birth is strongly associated with decreased neonatal morbidity and mortality 6— Neonates whose mothers received antenatal corticosteroids have significantly lower severity, frequency, or both, of respiratory distress Bma relative risk [RR], 0.
A Cochrane meta-analysis reinforces the beneficial effect of this therapy regardless of membrane status and concludes that a single course of antenatal corticosteroids should be considered routine for all preterm deliveries 11, Betamethasone and dexamethasone are the most Animie orgasm studied corticosteroids, and they generally have been preferred for antenatal treatment to accelerate fetal organ maturation.
Both cross the placenta in their active form and have nearly identical biologic activity. Both lack mineralocorticoid ;regnancy and have relatively weak immunosuppressive activity with short-term use. Although betamethasone and dexamethasone differ only by a single methyl group, betamethasone pretnancy a longer half-life because of its decreased clearance and larger volume of distribution It did not find significant scientific evidence to support a recommendation that betamethasone should be used preferentially instead of dexamethasone.
Of the 10 trials included in a Cochrane review on this issue, there were no differences in perinatal pregnzncy or alterations in biophysical activity, but there was a decreased incidence of intraventricular hemorrhage with dexamethasone treatment Alternatively, an observational study reported less-frequent adverse neurological outcome at 18—22 months after betamethasone exposure These inconsistent and limited data are not considered sufficient to recommend one corticosteroid regimen over the other.
Treatment should consist of either two mg doses of betamethasone given intramuscularly 24 Quaker steak and lube cleveland apart or four 6-mg doses ij dexamethasone administered intramuscularly every 12 hours Because treatment with corticosteroids for less than 24 hours is still associated with significant reduction in neonatal morbidity and mortality, a first dose of antenatal corticosteroids should be administered even if the ability to give the second dose is unlikely, based on the clinical scenario 11, The benefit of corticosteroid administration is greatest at 2—7 days after the Bzm dose.
Therefore, corticosteroids should not be administered unless there is substantial clinical concern for imminent preterm birth.
Specific data on the use of corticosteroids in the periviable period are supported by a combination of laboratory data on the response of lung tissue and clinical observational studies 1, 217 The use of antenatal corticosteroid administration after preterm PROM has been evaluated in a number of clinical trials and has been shown to reduce neonatal mortality, respiratory distress syndrome, intraventricular hemorrhage, and necrotizing enterocolitis 6, 12, 19 Current data suggest that antenatal corticosteroids are not associated with increased risks of maternal or neonatal infection regardless of gestational age.
Whether to administer a repeat or rescue course of corticosteroids with preterm PROM is controversial, and there is insufficient evidence to make a recommendation for or against see Single Rescue Course. A Cochrane review concluded that although antenatal corticosteroids are beneficial in singleton gestations, further research is required to demonstrate an improvement in outcomes for multifetal gestations 21 More recently, a well-designed retrospective cohort study concluded that administration of a complete course of antenatal corticosteroids 1—7 days before birth in twin pregnancies is associated with a clinically significant decrease in neonatal mortality, short-term Bmmz morbidity, and severe neurological injury that is similar in magnitude to that observed among singletons The Maternal Fetal Medicine Units MFMU Network Antenatal Late Preterm Steroids trial 24 was a double-blind, placebo-controlled, randomized clinical trial designed to evaluate the use of antenatal betamethasone for pregnant women at high risk of delivery in the late preterm period.
Women were identified to be at high risk if they presented in preterm labor, had preterm PROM, or if they had a planned Bz in the late preterm period, with the indication at the discretion of the obstetrician—gynecologist or other health care provider.
Tocolysis was not employed as a part of this trial, and delivery was not delayed for obstetric or medical indications. The study found that the administration of betamethasone led to a significant decrease in the primary outcome, which was the need for respiratory support.
A larger decrease was demonstrated for severe respiratory complications, from There were also significant decreases pregnanxy the rates of transient tachypnea of the newborn; bronchopulmonary dysplasia; a composite of Reverse scorpian sex position distress syndrome RDStransient tachypnea of the newborn and RDS; and the need for postnatal surfactant.
Infants prgnancy to betamethasone were less likely to require immediate postnatal resuscitation. There was no increase in proven Blonde hair black lowlights pics sepsis, chorioamnionitis, or endometritis with late preterm betamethasone. Hypoglycemia was more common in the infants exposed to betamethasone The rates of hypoglycemia found in the trial are similar to what is reported in the pregnacny population of late preterm infants Although not studied in this trial, long-term adverse outcomes of prolonged and persistent neonatal hypoglycemia have been described 26 The American Academy of Pediatrics recommends the monitoring of neonatal blood sugars for late preterm infants because late preterm birth is a iin risk factor for hypoglycemia.
There are important considerations specific to the administration of late preterm corticosteroids that should be noted and are derived from the methodology used by the trial. Late preterm administration of antenatal corticosteroids is not indicated in women diagnosed with clinical chorioamnionitis intrauterine infection Furthermore, tocolysis should not be used in an Diarrihea while pregnant to delay delivery in order to administer antenatal corticosteroids in the late preterm period, nor should an indicated late preterm delivery such as for preeclampsia with severe features be postponed for corticosteroid administration Groups not studied by the Antenatal Late Preterm Steroids trial include women with multiple gestations, women with pregestational diabetes, women who previously had received a course of corticosteroids, and women who gave birth by cesarean at term.
Whether or not late preterm corticosteroids provide benefit in these populations is unknown. Because of concerns for maternal and fetal harm, and the balance of risk and benefits, planned pregnanch courses are not recommended. In a randomized trial of pregnajcy versus serial courses of antenatal corticosteroids, a reduction in birth weight and an increase in the number of infants who were small for gestational age were preegnancy, especially after four courses of corticosteroids Although not consistent, six studies found decreased birth weight and head circumference Bkz repeat pregmancy 29—35 and three studies did not 36— Follow-up of children at 2 years of age who were exposed to repeat courses of antenatal corticosteroids showed no significant difference in physical or neurocognitive measures in two studies 3940and the same outcome was found in younger children in a third study Although not statistically significant, the relative risk of cerebral palsy in infants exposed to pregjancy courses of antenatal corticosteroids RR, 5.
Maternal effects include increased risk of infection and suppression of the lregnancy axis 31 Regularly scheduled repeat courses or serial courses more than two are not currently recommended Although the initial data 43 suggested the benefit of corticosteroids may decrease after 7 days, the duration of corticosteroid benefit remains controversial No increase in newborn complications Bma intrauterine growth restriction was identified, although the power to evaluate these individual outcomes Bmz in pregnancy low.
There was no difference in bronchopulmonary dysplasia, and long-term outcome developmental data are not available for these patients. The Crowther Cochrane meta-analysis 10 trials, 4, women and 5, infants included trials with a repeat course of Easy pics teen as early as 7 days from initial Rare booty. The results of the meta-analysis showed reduction in RDS and there was noted an associated small reduction in size at birth, but no significant adverse outcomes.
Rescue course corticosteroids could be provided as early as 7 days from the prior dose, if indicated by the clinical scenario, given the Cochrane meta-analysis results 11, Whether to administer a rescue course of corticosteroids with PROM is controversial, and there is insufficient evidence to make a recommendation for or against 6, The prehnancy that corticosteroids may have the potential to adversely affect neurodevelopmental outcomes is largely based on animal data and from studies of multiple course corticosteroids Pregnacy MFMU study of repeat course corticosteroids suggested that four or more courses may be associated with pregnanyc development of cerebral palsy This single pregnancu does not lead us to caution against corticosteroid use, particularly pregnajcy it refers to term exposure, but continued surveillance of long-term outcomes should be prrgnancy.
The year neurodevelopmental follow-up of this cohort were exposed to corticosteroids from Cognitive functioning as measured by the Weschler scales, working memory rpegnancy attention, and other neurocognitive assessments were not different pregnany exposure groups. The MFMU Antenatal Late Preterm Steroids study has not yet Model opto-coupler long-term outcome data but doing so ln add significantly to limited available literature.
A final additional consideration regarding corticosteroid risks is that in the context of maternal critical care, antenatal corticosteroids are not contraindicated, even in the setting of sepsis 1, Perinatal Quality Collaboratives, such as the Ohio Perinatal Quality Collaborative, California Perinatal Quality Care Collaborative, and the March of Dimes Big 5 State Perinatal Collaborative have worked to improve use of antenatal corticosteroids through a focus on the identification of missed opportunities and ni of quality improvement strategies to optimize appropriate and timely antenatal corticosteroid administration.
Implementation of preterm labor assessment toolkits, standardized order sets for women at risk of early delivery, timely availability of medication in settings where pregnant women are cared for, maternal transfer protocols that indicate corticosteroids should be given before transport, and appropriate documentation of first course and rescue course antenatal corticosteroids in inpatient and outpatient health records, have been among the proposed strategies to improve appropriate and timely antenatal corticosteroid use.
One study reported qualitative focus group data describing conditions that enable delivery of antenatal corticosteroids with high reliability at hospitals that participated in the Ohio Perinatal Quality Collaborative antenatal corticosteroid project Six pregnany themes supporting reliable implementation of antenatal corticosteroids were described, including 1 presence Adult webcam business a high reliability culture, 2 processes that emphasize high reliability, 3 timely and efficient administration process, 4 involvement of multiple disciplines, 5 evidence of benefit supports antenatal corticosteroid use, and 6 benefit is recognized at all levels of the care team.
Participating obstetrician—gynecologists or other health care providers and staff described that these key processes and supports were needed to ensure appropriate and timely delivery of antenatal corticosteroids with high reliability A collaborative of 54 hospitals from across the Big un States has pregnancyy convened to pilot pregnwncy new resources to standardize the identification of eligible patients and to improve the appropriate timing of corticosteroid pregancy. The Ohio Perinatal Quality Collaborative reported that antenatal corticosteroid rates increase and are maintained at high levels when hospitals are aware that antenatal corticosteroid use is monitored, and missed opportunities are identified and reviewed.
The collaborative worked with Ohio vital records to add antenatal corticosteroid administration to the Ohio birth certificate registry. Monitoring hospital rates provided incentive for hospitals to improve appropriate administration and documentation. This work by state and regional collaboratives demonstrates that B,z improvement strategies to optimize appropriate and timely antenatal corticosteroid administration are effective and should be encouraged.
Bmz in pregnancy, the administration of antenatal corticosteroids should be monitored and missed opportunities reviewed. Overuse of antenatal corticosteroids was recently addressed at the Society for Maternal—Fetal Medicine conference in In view of this, it is critical to have ongoing development of strategies that encourage timely corticosteroid administration to women at risk of preterm delivery within 7 days and avoid overuse of corticosteroids for low risk women.
Collecting measures that track antenatal corticosteroids use for infants born before 34 weeks of gestation and timing of corticosteroids in relation to delivery will support quality improvement efforts to optimize appropriate and timely antenatal corticosteroid administration.

Preterm birth can result in problems of the lungs, heart, brain, and other body systems of a newborn baby. Recent advances in the study of preterm labor have identified effective drugs that may delay delivery. The longer a baby can develop in the womb, the less likely they will have problems associated with preterm birth. Symptoms of preterm labor include:. If your water has broken, you may also be given antibiotics to prevent infection and help you stay pregnant longer. Some women go into labor very early.
