Premature rupture of membranes refers to the breaking of the fetal membrane before the onset of labor, followed by the leakage of amniotic fluid. The greatest risk of premature rupture of membranes is the potential to cause an infection in the amniotic cavity. The symptoms of infection due to premature rupture of membranes include the following aspects:

First, the smell and color of the amniotic fluid will change. The amniotic fluid may become purulent and have a foul smell, which suggests an infection within the amniotic cavity.

Second, blood tests can reveal elevated infection markers, primarily an increase in white blood cells and C-reactive protein well above the normal range.

Third, the patient may experience contractions or lower abdominal tenderness and rebound pain. When there is an infection in the amniotic cavity, symptoms of peritonitis may occur, along with manifestations of contractions, presenting as episodic pain in the lower abdomen. These are the symptoms of infection from premature rupture of membranes.
