Resumen
Summary

The diagnosis of preterm labour is a relevant subject in obstetrics nowadays, as it is the principal cause of perinatal mortality in developed countries. Numerous factors are involved in preterm labour, and also in the risk for developing it. Biochemical and physical markers have been studied, to identify women with a high risk of delivering prematurely and to differentiate, when faced with a pregnant women with symptoms, if it is a true preterm labour or only a «threatened». The biochemical markers studied are cervicovaginal secretions and maternal serum, the other parameters studied are the length of the cervix and the uterine contractions. Of all these factors, fetal fibronectin in the cervicovaginal secretions and cervical shortening, are those that showed to have the greatest value in the prediction of a high risk of preterm delivery.

Resumen
Resumen

El diagnóstico del parto pretérmino es un tema relevante en la obstetricia actual,ya que éste es la primera causa de mortalidad perinatal en los países desarrollados. Son numerosos los factores que participan en la aparición de un parto prematuro,así como los factores de riesgo para su desarrollo. Se han estudiado marcadores bioquímicos y físicos para identificar a las mujeres con alto riesgo de parir prematuramente y diferenciar,ante una gestante con síntomas,si se trata de un verdadero parto pretérmino o sólo de una «amenaza». Los marcadores bioquímicos son sustancias estudiadas en la secreción cervicovaginal y en el suero materno; otros parámetros estudiados son la longitud del cérvix y la dinámica uterina. De todos los factores,la fibronectina fetal en secreción cervicovaginaly el acortamiento del cérvix son los que han demostrado mayor valor en la predicción de un alto riesgo de parto pretérmino.
