If I experience bleeding during pregnancy, could this hurt my baby?

Yes, bleeding during pregnancy may cause injury to the baby. Bleeding during pregnancy could be caused by a number of things. One very serious condition that can cause bleeding is placental abruption (though abruption can also occur without visible bleeding). The placenta is an organ that connects the baby to the wall of the womb (uterus). Some of the placenta’s important functions include delivering nutrients and oxygen to the baby. Nutrients and oxygen travel from the mother to the placenta, and then through the umbilical cord to the baby. A placental abruption occurs when the placenta separates from the womb. The separation can be partial or complete. If the separation is complete, the baby will be totally cut off from the mother’s circulation and will therefore not be receiving any nutrients or oxygen, nor will the baby be able to get rid of waste products, such as carbon dioxide.

Placental Abruption


If a woman has one of the following risk factors for placental abruption, it is the duty of her physician to take these factors into account and provide care accordingly.

Risk Factors for Placental Abruption

Risk factors for placental abruption include:

  • Preeclampsia or high blood pressure. This is the most common cause of placental abruption, occurring in about 44% of cases.
  • Trauma or contractions during labor
  • Labor induction drugs such as Pitocin and Cytotec increase the risk of placental abruption because they cause uterine tachysystole (a complication in which contractions are stronger, more frequent, or longer-lasting; this can cause the placenta to tear away from the uterus).
  • Sudden decompression of the uterus from events such as the delivery of the first child in a multiples birth or premature rupture of membranes (mother’s water breaking too soon)
  • Accidental puncture of the placenta from a needle (e.g. amniocentesis)
  • Chorioamnionitis (an infection of the two membranes of the placenta – the chorion and the amnion – and the amniotic fluid.)
  • Abnormal uterine blood vessels
  • Previous placental abruption
  • Mother over the age of 35 or younger than 20
  • Male baby
  • Elevated maternal serum alpha-fetoprotein in the second trimester
  • Other less common causes include cocaine use, uterine fibroids, injury to the uterus (e.g. car accident), alcohol use, and cigarette smoking.

Signs of Placental Abruption

Signs of placental abruption include:

  • Bleeding during the second half of pregnancy or excessive bleeding during labor
  • Mild or intense abdominal pain
  • Back pain
  • Uterine contractions during labor that last longer than normal
  • Uterine irritability
  • Uterus that becomes hard to the touch during labor
  • ­Disproportionately enlarged uterus
  • Identification of bleeding behind the placenta (retroplacental hematoma) on ultrasound
  • Debris in the amniotic fluid, thickened placenta, and collection of fluid around the maternal-fetal membranes on ultrasound
  • Blood tests, such as a fibrinogen level and DIC, can help reveal the degree of abruption and bleeding.
  • Maternal low blood pressure (hypotension) and fetal heart rate abnormalities suggest significant placental separation that could result in severe oxygen deprivation or death.

Small Amounts of Bleeding Can Signal a Larger Problem

Bleeding can be concealed and therefore not escape through the vagina; thus, when abdominal pain and uterine contractions are present, a patient should be carefully evaluated for abruption even if there is minimal or no vaginal bleeding.
