Preterm birth at 32 weeks 4 days, with a weight of 2,000 g attached to medical equipment. Tertiary interventions are aimed at women who are about to go into preterm labor, or rupture the membranes or bleed preterm. The use of the fibronectin test and ultrasonography improves the diagnostic accuracy and reduces false-positive diagnosis.
Tocolytics are used in preterm labor, which refers to when a baby is born too early before 37 weeks of pregnancy. As preterm birth represents one of the leading causes of neonatal morbidity and mortality, the goal is to prevent neonatal morbidity and mortality through delaying delivery and increasing gestational age by gaining more time for other management strategies like corticosteroids ...
A preterm birth, also known as premature birth, is defined as babies born alive before 37 weeks of pregnancy are completed. [40] There are three types of preterm births: extremely preterm (less than 28 weeks), very preterm (28 to 32 weeks) and moderate to late preterm (32 to 37 weeks). [40]
According to the WHO, a preterm birth is defined as "babies born alive before 37 weeks of pregnancy are completed." [20] According to this classification, there are three sub-categories of preterm birth, based on gestational age: extremely preterm (fewer than 28 weeks), very preterm (28 to 32 weeks), moderate to late preterm (32 to 37 weeks).

[2] [3] Pre-eclampsia increases the risk of undesirable as well as lethal outcomes for both the mother and the fetus including preterm labor. [11] [12] [3] If left untreated, it may result in seizures at which point it is known as eclampsia. [2] Risk factors for pre-eclampsia include obesity, prior hypertension, older age, and diabetes mellitus.
Preterm premature rupture of membranes (PPROM) is when water breaks both before the onset of labor and before the pregnancy's 37 week gestation. [3] [4] In the United States, more than 120,000 pregnancies per year are affected by a premature rupture of membranes, which is the cause of about one third of preterm deliveries. [5]
Low birth weight may be a result of preterm birth.. Low birth weight (LBW) is defined by the World Health Organization as a birth weight of an infant of 2,499 g (5 lb 8.1 oz) or less, regardless of gestational age. [1]
Adults born preterm have higher all-cause mortality rates as compared to full-term adults. Premature birth is associated with a 1.2x to 1.6x increase in all-cause mortality rates during early to mid-adulthood. Those born extremely prematurely (22–27 weeks) have an even higher mortality rate of 1.9x to 4.0x. [3]
