Pregnant women with red cell antibodies, who are assessed as being at high risk of requiring a blood transfusion, should have a cross-match sample taken at least every week.

Current BCSH guidelines require a sample no more than 72 hours old for providing compatible blood in
pregnancy,but do allow a deviation to the 3-day rule for individual cases such as high-risk women with placenta praevia without red cell antibodies where weekly samples can be taken, as long as a risk assessment is made and recorded in each individual case

In high-risk women with red cell antibodies where a sample every 72 hours is not feasible, a sample should be taken once a week and if transfusion is required a new sample should be taken immediately, to exclude new antibody development. However, in the event of life threatening haemorrhage, urgent transfusion should not be delayed and close liaison with the hospital transfusion laboratory is vital.

Undertake a urine dipstick test in all women presenting with urinary

Antenatal thromboprophylaxis for those with previous VTE should begin as early in pregnancy as practical.

Women with previous VTE should be offered prepregnancy counselling, and a  prospective management plan for thromboprophylaxis in pregnancy should be made. Those who become pregnant beforemreceiving such counselling should be referred at the earliest opportunity in pregnancy to a clinician
with expertise in thrombosis in pregnancy.

Well done for taking the quiz ! Small steps taken everyday make a huge difference.

Systemic chemotherapy is contraindicated in the first trimester because of a high rate of fetal

CTPA is associated with relatively high radiation dose (up to 20 mGy) to the mother’s breast tissue, which is associated with an increased risk of breast cancer.

The dose estimate for CTPA is 20 to 100 times greater.
