Fetal Fibronectin Test

These births represent 75% of neonatal deaths not related to birth. The dramatic decline in infant mortality in the United States over the past 30 years is attributable to significant improvements in neonatal intensive care, and not a reduction in the number of babies born early. It is very disheartening that the rate of premature births in this country has not changed since record keeping began in the 1950s.

What prematurity?

Prematurity was defined as birth before 37 weeks of gestation, calculated from the first day of the last normal menstrual period. A baby is considered full term if born within two weeks following the date "reasonable" (40 weeks after the last period). The smallest premature babies (weighing less than 1500 grams) are two hundred times more likely to die during the first year of life than babies born weighing over 2,500 grams. Even if they survive, these very small babies are 10 times more at risk of long-term problems such as vision and hearing complications, chronic pulmonary disease, cerebral palsy and other neurological disorders.

What is preterm labor?

Preterm labor is defined as regular contractions of the uterus, plus a change in the amount of the opening and thinning of the cervix before the 37th week of gestation. perception of a woman's contractions varies, and studies have not shown that the systematic examination of the cervix during pregnancy is helpful in detecting preterm labor. Maternity care providers struggle with the diagnosis. Half of all women with a diagnosis of preterm labor (they have contractions and cervical change) switch to full-term pregnancy without any treatment. Twenty percent of women who do not meet the criteria of preterm birth (they have contractions, but the neck does not change, for example), return to provide premature anyway.

What are the causes of preterm labor and birth?

Despite serious efforts to reduce premature births, there is little good news. The factors that begin a normal life, term labor are poorly understood, and premature labor is more perplexing. Researchers have tried to identify the causes of preterm labor and birth, women who are at risk, and ways to prevent or treat premature labor. Very few clear answers have emerged.

The most common cause of premature birth is unknown. Sometimes, malformations of the uterus or cervix are associated with early delivery. Often, these are unknown to the wife before becoming pregnant. Although it is known how a uterine fibroid or unusually shaped uterus will affect the pregnancy is often difficult to predict.

One of the causes of preterm labor is premature (before onset of labor), preterm (before full term) rupture of membranes. It is not known why the fetal membranes ruptured prematurely in some pregnancies. When the fluid leaks around the baby, the baby and mother are exposed to infection. Labor usually occurs within days. Babies born too soon face major problems, and the infection worsens the situation.

Infections of the vagina, cervix, and uterus have been studied as possible causes of premature rupture of membranes. When infection is present in the vagina or cervix, the toxins produced by the body can weaken the membranes, making them more likely to leak or rupture. Inflammation from infection causes local release of a substance known as prostaglandin. Prostaglandins are found throughout the body and the substance is supposed to have some role in the onset of labor. Why do some women have infections without premature rupture of membranes or preterm labor is unknown. Organization.
