Iron prophylaxis in pregnancy: Intravenous route versus oral route


Bencaiova, G; von Mandach, U; Zimmermann, R (2009). Iron prophylaxis in pregnancy: Intravenous route versus oral route. European Journal of Obstetrics and Gynecology and Reproductive Biology, 144(2):135-139.

Abstract

OBJECTIVE: To assess and compare the efficacy and safety of two and three doses of intravenous iron sucrose with daily oral ferrous sulphate in the prophylaxis of iron deficiency anaemia in pregnant women. STUDY DESIGN: 260 women with singleton pregnancy who met inclusion criteria and who gave informed consent were randomised between the 21st and 24th week into either the intravenous iron group or the oral iron group. Of 130 women in the intravenous iron group, 75 women received two doses of 200mg iron sucrose and 55 three doses of 200mg iron sucrose. The first dose was administered between the 21st and 24th gestational weeks, the second between the 28th and 32nd and the third between the 35th and 37th. The women of the oral group were given oral tablets of 80 mg ferrous sulphate daily, beginning on the day of study enrolment and stopping on the day of delivery. RESULTS: There was a non-significant trend to a higher frequency of responders (haemoglobin> or =11 g/dl) in the intravenous iron group (75 vs. 80%). There was a significant difference of repleted iron stores before delivery (ferritin>50 microg/l) in the group with three intravenous iron doses in comparison to the oral iron group (49 vs. 14%; p<0.001). No differences were observed in regard to maternal and perinatal outcomes. CONCLUSIONS: There was no clinically significant difference in the haematological, maternal and foetal outcomes in the parenteral route of iron prophylaxis in pregnant women.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
