OBG · Complications of pregnancy: trauma

Sample item

A 32-week pregnant woman has a low-speed road traffic accident with minor abdominal bruising and is haemodynamically stable. Fetal heart is normal. What is the most appropriate monitoring plan?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Continuous cardiotocography for at least 4 to 6 hours with Rh status check and anti-D if Rh negative

Blunt trauma can cause concealed placental abruption even with minimal maternal injury, which usually declares itself within 4 to 6 hours. Cardiotocography for at least that period is recommended, and a Kleihauer-Betke test helps quantify fetomaternal haemorrhage for anti-D dosing in Rh-negative women. Any contractions, bleeding or abnormal tracing prolong observation.

Option by option

  • A. Routine bed rest for a week without monitoring

    Bed rest does not replace monitoring.

  • B. Immediate caesarean section

    Caesarean is not indicated with a normal fetal heart and stable mother.

  • C. Continuous cardiotocography for at least 4 to 6 hours with Rh status check and anti-D if Rh negative (correct)

    Correct. Monitoring detects occult abruption, and anti-D is given if Rh negative.

  • D. Discharge immediately since she is stable

    Stable women can still have concealed abruption, so discharge without monitoring is unsafe.
