TREATMENTS FOR ANAEMIA IN PREGNANCY THOUGHT TO BE DUE TO IRON DEFICIENCY

When the blood has insufficient red cells, or the red cells carry insufficient haemoglobin to deliver adequate oxygen to the tissues, this is called anaemia. There is normally a reduction in the haemoglobin concentrations in the mother’s blood during pregnancy, and this allows a better blood flow around the womb (uterus) and to the baby. This is sometime called physiological anaemia and needs no treatment. True anaemia, however, can be mild, moderate or severe and can cause weakness, tiredness and dizziness. Severe anaemia makes women at risk of cardiac failure and is very common in low-income countries Anaemia has many causes including a shortage or iron, folic acid or vitamin B12. These are all required for making red cells and are available in a good diet. Iron shortage, however, is the most common cause of anaemia during pregnancy. Iron treatment can be given by mouth (oral), by injection into the muscle (intramuscular) or injection into the vein (intravenous). Blood transfusion or giving something which stimulates the body to produce more red cells (erythropoietin) are also possible treatments.

In this review, we identified 23 trials involving 3198 pregnant women. Many of the trials were in low-income countries and many treatment variations were studied. Oral iron reduced the incidence of anaemia but is known to sometimes cause constipation and nausea. Although the intramuscular and intravenous routes produced better levels of red cells and iron stores than the oral route, no clinical outcomes (such as pre-eclampsia, preterm births, postpartum haemorrhage) were assessed and there were insufficient data on adverse effects. Intravenous treatment can cause venous thrombosis (blockages in the veins) and intramuscular treatment causes important pain and discolouration at the injection site. It was unclear if women and babies were healthier when women were given iron for mild or moderate anaemia during pregnancy. There were no studies on using blood transfusions.

Overall, there was insufficient evidence to say when or how anaemia in pregnancy needs to or should be treated.  —Cochrane Jan 2012
