What should you know about placental abruption side effects?

Placental abruption happens when the placenta separates from the wall of the uterus before birth. Separation can reduce the placenta’s ability to deliver oxygen and nutrients to the baby. The pregnant person may have abdominal or back pain, a firm or tender uterus, contractions, or vaginal bleeding; visible blood may not match the amount of bleeding inside the uterus. The baby may show changes in movement or heart-rate monitoring. Severe bleeding can cause dizziness, weakness, or signs of shock and may affect blood clotting.

Treat suspected placental abruption as an obstetric emergency. Stop exertion, arrange urgent transport to a maternity unit, and do not drive yourself if you feel faint or unwell. Tell the maternity team how far along the pregnancy is, when the pain or bleeding started, whether the baby is moving normally, and whether there was a fall or abdominal impact. Assessment may include examination, monitoring of the baby’s heart rate, blood tests, and ultrasound, although ultrasound does not always show the separation. Treatment depends on bleeding, pregnancy stage, and the condition of both patients; delivery may be needed, including a Caesarean Section.

Call emergency services or go to the nearest maternity emergency department for vaginal bleeding, sudden abdominal or back pain, a hard or tender abdomen, repeated contractions, reduced or absent fetal movement, faintness, breathlessness, cold clammy skin, or rapid worsening. Do not wait for bleeding to appear: internal bleeding and fetal distress can develop without blood leaving the vagina.

Ask what monitoring is needed, whether the placenta appears separated, how the baby is responding, which warning signs require immediate return, and how delivery planning may change if bleeding or fetal distress develops.
