ACOG committee opinion no. 560: Medically indicated late-preterm and early-term deliveries.

چکیده
The neonatal risks of late preterm (34 0/7-36 6/7 weeks of gestation) and early-term (37 0/7-38 6/7 weeks of gestation) births are well established. However, there are a number of maternal, fetal, and placental complications in which either a late-preterm or early-term delivery is warranted. The timing of delivery in such cases must balance the maternal and newborn risks of late-preterm and early-term delivery with the risks of further continuation of pregnancy. Decisions regarding timing of delivery must be individualized. Amniocentesis for the determination of fetal lung maturity in well-dated pregnancies generally should not be used to guide the timing of delivery.

Delivery and late preterm birth
Delivery of infants who are physiologically mature and capable of successful transition to the extrauterine environment is an important priority for obstetric practitioners. During the past 15 years in the United States the percentage of infants born before 40 weeks’ gestation has dramatically increased and the percentage of infants born after 40 weeks’ gestation has decreased. In this shift se...
متن کاملPrepregnancy body mass index and risk of preterm birth: association heterogeneity by preterm subgroups
BACKGROUND To evaluate the association between prepregnancy body mass index (BMI) is associated with early vs. late and medically-induced vs. spontaneous preterm birth (PTB) subtypes. METHODS Using data from the Boston Birth Cohort, we examined associations of prepregnancy BMI with 189 early (<34 completed weeks) and 277 late (34-36 completed weeks) medically-induced PTBs and 320 early and 61...
متن کاملIs maternal trait anxiety a risk factor for late preterm and early term deliveries?
BACKGROUND Anxiety is associated with preterm deliveries in general (before week 37 of pregnancy), but is that also true for late preterm (weeks 34/0-36/6) and early term deliveries (weeks 37/0-38/6)? We aim to examine this association separately for spontaneous and provider-initiated deliveries. METHODS Participants were pregnant women from the Norwegian Mother and Child Cohort Study (MoBa),...
متن کاملA multistate quality improvement program to decrease elective deliveries before 39 weeks of gestation.
OBJECTIVE Nonmedically indicated (elective) deliveries before 39 weeks of gestation result in unnecessary neonatal morbidity. We sought to determine whether implementation of a process improvement program will decrease the rate of elective scheduled singleton early-term deliveries (37 0/7-38 6/7 weeks of gestation) in a group of diverse community and academic hospitals. METHODS Policies and p...
متن کاملCommentary: Mediation and moderation analyses: a novel approach to exploring the complex pathways between maternal medical conditions, preterm birth and associated newborn morbidity risk.
Whereas infants born at earlier gestational ages suffer the greatest morbidity and mortality, adverse health consequences of late preterm and early term births are also well documented. The aetiology of preterm birth is multifactorial and the pathways leading to it probably vary with gestational age. They include infection or inflammation, uteroplacental ischaemia or haemorrhage, uterine overdi...
