ABSTRACT

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. Postterm births are easily preventable by intervening to deliver with the use of induction of labor. Thus, this potentially problematic condition deserves further attention and careful consideration. The focus of this article is to review and challenge some current concepts surrounding the diagnosis and management of prolonged pregnancy. We outline how to identify those women with prolonged pregnancy and which is the appropriate moment to start monitoring the fetal wellbeing. Finally we address the question of benefits and hazards of induction of labor strategies.

ABSTRACT

Preterm birth (PTB) is usually defined as a delivery before 37 completed weeks or 259 days of gestation. World Health Organization estimates a worldwide incidence of PTB of 9.6%. Infants born preterm are at higher risks than infants born at term for mortality, and acute and chronic morbidity. Major causes of PTB are the following: spontaneous preterm labor with intact membranes (50%), labor induction or caesarean delivery for maternal or fetal indications (30%), and preterm premature rupture of membranes or PPROM (20%). The aim of this review is to analyze this medical condition, focusing on cellular and biochemical mechanisms, maternal risk factors and role of inflammation and infections in preterm premature rupture of membranes (PPROM) and PTB. Moreover we will discuss about the proper therapeutic strategies for its management. Although different methods have been introduced to predict the advent of preterm labour in asymptomatic women, possibilities for real primary prevention are rare. An early estimation of potential risk factors is pivotal in the secondary prevention of PTB. Finally most efforts so far have been tertiary interventions. These measures have reduced perinatal morbidity and mortality. Advances in primary and secondary care will be needed to prevent prematurity-related illness in infants and children.
