INTRODUCTION: This study aimed to determine the effects of induction of labour in late-term pregnancies on the mode of delivery, maternal and neonatal outcome. METHODS: We retrospectively analyzed deliveries between 2000 and 2014 at the University Hospital of Cologne. Women with a pregnancy aged between 41 + 0 to 42 + 6 weeks were included. Those who underwent induction of labour were compared with women who were expectantly managed. Maternal and neonatal outcomes were evaluated...

UNLABELLED: This review presents the up-to-date information from published resources on the issue of Posterm pregnancy (Medline, Cochrane Database, ACOG, RCOG, SOGC) and complements the presented guidelines. The most of resources are using the term "postterm pregnancy" for pregnancy reaching or exceeding 42+0 weeks and days of gestation, while late pregnancy is defined as a period in between 41+0 and 41+6.The exact determination of gestational age is necessary for exact diagnosis and appropriate management of late and postterm pregnancy, because these pregnancies have increased risk of perinatal morbidity and mortality...

BACKGROUND: Observational data shows that postterm pregnancy (≥42 gestational weeks, GW) and late term pregnancy (≥41 GW), as compared to term pregnancy, is associated with an increased risk for adverse outcome for the mother and infant. Standard care in many countries is induction of labour at 42 GW. There is insufficient scientific support that induction of labour at 41 GW, as compared with expectant management and induction at 42 GW will reduce perinatal mortality and morbidity without an increase in operative deliveries, negative delivery experiences or higher costs...

Prolonged pregnancy is defined as a pregnancy that extends beyond 42 weeks of gestation (294 days) from the first day of the last normal menstrual period. An accurate estimation of the 'natural' incidence of prolonged pregnancy would require meticulous early pregnancy dating. The use of ultrasound to establish gestational age reduces the number of pregnancies that are classified as prolonged. Prolonged pregnancy is associated with an increased perinatal mortality and morbidity in pregnancies which appear to be otherwise low risk...

It is a commonly held belief that labor induction increases the risk of cesarean delivery; women who are induced are at higher risk of cesarean as compared with those in spontaneous labor. This comparison group is inaccurate, however, as women and providers cannot choose spontaneous labor as the alternative to labor induction. With expectant management, spontaneous labor may occur, but as gestation advances, pregnancy complications may occur, or women may progress postterm requiring induction at a later gestation...

Pregnancy is considered late term from 41 weeks, 0 days' to 41 weeks, 6 days' gestation, and postterm at 42 weeks' gestation. Early dating of the pregnancy is important for accurately determining when a pregnancy is late- or postterm, and first-trimester ultrasonography should be performed if clinical dating is uncertain. Optimal management of a low-risk, late-term pregnancy should consider maternal preference and balance the benefits and risks of induction vs. waiting for spontaneous labor. Compared with expectant management, induction at 41 weeks' gestation is associated with a small absolute decrease in perinatal mortality and decreases in other fetal and maternal risks without an increased risk of cesarean delivery...

Postterm pregnancy refers to a pregnancy that has reached or extended beyond 42 0/7 weeks of gestation from the last menstrual period (LMP), whereas a late-term pregnancy is defined as one that has reached between 41 0/7 weeks and 41 6/7 weeks of gestation (). In 2011, the overall incidence of postterm pregnancy in the United States was 5.5% (). The incidence of postterm pregnancies may vary by population, in part as a result of differences in regional management practices for pregnancies that go beyond the estimated date of delivery...

Postterm pregnancy is a pregnancy that extends to 42 weeks of gestation or beyond. Fetal, neonatal and maternal complications associated with this condition have always been underestimated. It is not well understood why some women become postterm although in obesity, hormonal and genetic factors have been implicated. The management of postterm pregnancy constitutes a challenge to clinicians; knowing who to induce, who will respond to induction and who will require a caesarean section (CS). The current definition and management of postterm pregnancy have been challenged in several studies as the emerging evidence demonstrates that the incidence of complications associated with postterm pregnancy also increase prior to 42 weeks of gestation...

With the advent of ultrasound as a means of providing quality antenatal care, there is an increase in the diagnosis of nuchal cord in fetuses. The major cause of foetal or neonatal death during labor and in postpartum period is birth asphyxia and tight nuchal cord is a cause of birth asphyxia. Whilst there are instances in which fetuses with 3 to 4 loops of cord around the neck have been delivered by normal vaginal delivery, some cases have to be delivered by caesarean section due to foetal distress caused by a single loop of cord around the neck...

The designation term pregnancy and the distinction between term, preterm, and postterm pregnancy carry with them significant clinical implications with respect to the management of pregnancy complications. Although the potential hazards of both preterm birth and postterm pregnancy have been long recognized, little attention has, until recently, been given to the differential morbidity experienced by neonates born at different times within the 5-week interval classically considered term gestation. This article is a reevaluation of the concept of term pregnancy in light of current data...

AIMS: This study aimed to describe booking and transfer criteria and procedures available in birth centres in Australia in 2007 and to compare results with those of a previous national birth centre study undertaken in 1997. BACKGROUND: Approximately 2% of women who give birth in Australia each year do so in a birth centre. A national study on birth centre procedures was conducted in 1997. There have been changes in the management of women in birth centres during the past 10 years and this may be due in part to changes in booking and transfer criteria...

Term birth (37-41 weeks of gestation) has previously been considered a homogeneous group to which risks associated with preterm (less than 37 weeks of gestation) and postterm births (42 weeks of gestation and beyond) are compared. An examination of the history behind the definition of term birth reveals that it was determined somewhat arbitrarily. There is a growing body of evidence suggesting that significant differences exist in the outcomes of infants delivered within this 5-week interval. We focus attention on a subcategory of term births called "early term," from 37 0/7 to 38 6/7 weeks of gestation, because there are increasing data that these births have increased mortality and neonatal morbidity as compared with neonates born later at term...

A pregnancy reaching 42 completed weeks (294 days) is defined as postterm (PT). The use of ultrasound in early pregnancy for precise dating significantly reduces the number of PT pregnancies compared to dating based on the last menstrual period. Although the fetal, maternal and neonatal risks increase beyond 41 weeks, there is no conclusive evidence that prolongation of pregnancy, per se, is the major risk factor. Other specific risk factors for adverse outcomes have been identified, the most important of which are restricted fetal growth and fetal malformations...

Randomized clinical trials have shown that induction of labour does not result in higher caesarean delivery rates in women who are postterm. Despite this evidence, the policy of inducing women who are postterm is not generally applied in the Netherlands. This provides us with the opportunity to assess whether the findings from randomized studies can also be observed in nonrandomized studies and to validate these findings in the Dutch obstetric population. We performed a retrospective matched cohort study (1:1 ratios for both age and parity) in women with uncomplicated pregnancies of 42 weeks' duration and compared induction of labour with a policy of serial antenatal monitoring...

OBJECTIVE: The objective of the study was to examine risk factors for postterm (gestational age >or= 42 weeks) or prolonged (gestational age >or= 41 weeks) pregnancy. STUDY DESIGN: We conducted a retrospective cohort study of all term, singleton pregnancies delivered at a mature, managed care organization. The primary outcome measures were the rates of pregnancies greater than 41 or 42 weeks' gestation. Multivariable logistic regression models were used to control for potential confounding and interaction...

PURPOSE OF REVIEW: Prolonged (postterm) pregnancies are associated with both fetal and maternal complications. A variety of management practices can be utilized to mitigate the risk of these complications. RECENT FINDINGS: In addition to routine induction of labor at 41 weeks, a number of alternative management strategies show promise in preventing adverse fetal outcomes. The routine use of ultrasonography for pregnancy dating lowers the rate of postterm pregnancy and is associated with less need for induction of labor...

UNLABELLED: Postterm pregnancy is defined as one which has progressed to 42 0/7 weeks or beyond. The most common reason to be diagnosed with a postterm pregnancy is inaccurate pregnancy dating, but it is also associated with obesity, nulliparity, and a prior history of postterm pregnancy. The rate of postterm pregnancy appears to be decreasing whether due to improved pregnancy dating or an increase in induction of labor. Postterm pregnancy is associated with both maternal and neonatal morbidity and fetal and neonatal mortality; similarly pregnancies beyond 41 weeks' gestation are associated with increases in these perinatal complications...

REVIEW
G Beucher, M Dreyfus
The classic pregnancy term is between 37 and 42 weeks of gestation and the perinatal mortality and morbidity rates increasing progressively during this period, it is difficult to decide of an "ideal" term above which a medical intervention (induction of labour) brings more benefits than risks linked to the natural evolution of pregnancy. There is a good scientific evidence for the induction of labour from 41 weeks of gestation, defined like "postdating" term, when the cervical conditions are favourable (Bishop score>5) and systematically from 42 weeks (significative reduction of perinatal mortality rate and not increased rate of cesarean delivery compared with expectant management)...
