Premature rupture of membranes

Premature rupture of membranes

The rupture of membranes is a tissue injury that forms the amniotic sac, usually occurring at the beginning of labor, when the water breaks. Premature rupture of membranes refers to leakage of amniotic fluid in periods prior to labor. Occurrence of this phenomenon before the 37th week is possible in some cases and may affect pregnancy.
Almost all women who suffer from premature rupture of the membranes will give birth prematurely, most just a week after the onset of injury.

What are the risk factors?

  • if the membranes are subjected to internal or external pressures, are inflamed, thin or are prone to ruptures, then these pressures will certainly appear;
  • there are several infections that are associated with this condition: trichomonas vaginalis, mycoplasma, Chlamydia infection in trachomitis, gonorrhea, type B streptococci;
  • maternal stress can cause the release of substances that act as mediators that can cause the appearance of lesions;
  • smoking;
  • previous premature births;
  • vaginal leakage (especially bleeding);
  • disorders of the cervix;
  • poor nutrition.

The consequences of premature rupture of the membranes fall into three categories:

  • miscarriage and preterm birth;
  • complications during labor and the need to resuscitate the newborn;
  • infections.

How to diagnose premature rupture of membranes?

Generally, doctors realize that it is premature rupture of the membranes depending on the symptomatology that the pregnant woman presents:

  • loss of gelatin plug;
  • aqueous and abundant vaginal discharge;
  • urinary incontinence etc.

In addition, the doctor may use other tests to diagnose the condition:

  • valve examination (to identify an increased amount of amniotic fluid in the bottom of the posterior vaginal sac);
  • test with nitrazine paper (Ph indicator);
  • investigation of vaginal tact;
  • ultrasound.

Is premature rupture of membranes necessarily associated with premature birth?

It depends a lot on the moment when the membrane rupture occurs. Most women who suffer from this will give birth prematurely, most just 7 days after the onset of this complication.

There are a number of factors that favor the onset of preterm birth with premature rupture of membranes:

  • very low body mass index;

  • pulmonary diseases of the mother;

  • the onset of contractions within 2 weeks from the rupture of the membranes;

  • cervix short (less than 25 mm);

  • positive fetal fibronectin results;

  • bacterial vaginitis;

  • an earlier premature birth also caused by premature rupture of the membranes.

Depending on the period of the condition, the doctors will try to delay the birth. It is often recommended:

  • rest in bed;
  • intravenous fluid administration;
  • administration of drugs that inhibit contractions.
