Sample item

In which condition is the uterotonic methylergometrine contraindicated for management of postpartum haemorrhage?

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

The answer and the reasoning

D. Hypertension or pre-eclampsia

Methylergometrine causes sustained uterine contraction through serotonergic and alpha-adrenergic receptors, and it also produces vasoconstriction. This can precipitate dangerous hypertension, so it is avoided in hypertension, pre-eclampsia, and cardiac disease. Carboprost is avoided in asthma.

Option by option

  • A. Retained products after incomplete abortion

    It may be used to contract the uterus after evacuation if there is bleeding.

  • B. Prolonged labour

    Prolonged labour is a risk factor for atony, which it treats, so it is not a contraindication.

  • C. Uterine atony

    Uterine atony is the main indication for uterotonics.

  • D. Hypertension or pre-eclampsia (correct)

    Correct. Vasoconstriction and hypertensive crisis are the main hazards.
