This document provides guidelines on the prevention and management of anemia in pregnancy. It outlines that routine hemoglobin assessment should be done at booking and repeated in the mid and late trimester. It recommends iron supplementation during pregnancy. For hemoglobin levels below 11g/dl, it provides treatment guidelines based on hemoglobin and serum ferritin levels. It discusses oral and parental iron therapy options as well as blood transfusion indications. The document also provides guidance on management of anemia in labor.
3. 2.Iron Supplements In Pregnancy
T. Folic Acid 5mg OD in the first trimester (
13/52)
T Ferrous Fumarate 200mg -400mg OD +
T Folid Acid 5mg OD or
T Obimin 1 tablet/ day
4. 3.If Haemoglobin < 11g/dl
(a) Low MCV and MCH ( result available on the same day), no
history/ family history of haemoglobinopathy and clinically
no apparent medical illness:
Empirically treat as Iron Deficiency Anaemia
Investigation: FBC with PBF
Treatment:
1. T Ferrous Fumarate 400mg BD + T Folic Acid 5mg OD
2. Recheck Hb after 2-4 weeks
- Hb expected to rise by 0.3g to 1g per week
- If Hb rises as expected, continue with the same for
the rest of the pregnancy
5. If Hb does not rise,
- Ask about compliance and review full blood picture
- If patient compliant, perform the following
investigations:
serum ferritin
Hb electrophoresis
Stool for ova and cyst
Stool for occult blood
BFMP if patient from an endemic area
6. (b) If MCV and MCH not available on the same day ( i.e. in KD or
small MCH/ KK), no history/ family history of
haemoglobinopathy and clinically no medical illnesses:
Empirically treat as iron deficiency anaemia
Investigation: FBC with PBF
Treatment:
o T Ferrous Fumarate 400mg BD + T folic Acid 5mg OD
o Recheck Hb after 2-4 weeks ( Hb expected to rise by 0.3g -1g
per week)
7. o If FBP shows microcytic hypochromic anaemia ( iron
deficiency),
- If Hb rises as expected, continue the same treatment
for the rest of pregnancy
- If compliance not an issue, perform the following
investigations:
Serum Ferritin
Hb electrophoresis
Stool for ova and cyst
Stool for occult blood
BFMP if patient from an endemic area
8. o IF MCV and MCH is normal or high,
Refer to Antenatal Combined Clinic/ Antenatal
Specialist Clinic for further assessement and
management
9. 4. Categorization of Women Using Haemoglobin
And Serum Ferritin
Serum Ferritin Haemoglobin Diagnosis
( microgram/ l) (g/dl)
1 >12 >11 Normal, IDA excluded
2 <12 >11 Storage iron depletion
3 <12 <11 Iron deficiency anaemia
4 >12 <11 Other causes of anaemia
10. 5. Women with IDA
and unable to tolerate or non compliance to Ferrous
Fumarate,
Options include:
a. Change to different preparation
( i.e. T Iberet 1 tab BD)
b. Parenteral iron therapy
c. blood transfusion
11. 6. Elemental Iron Doses:
For prophylaxis against IDA, 30-100mg/day is
enough
For the purpose of treatment, at least 180mg/day is
required
12. Amount of elemental iron in different
preparations:
Preparation Elemental iron (mg/ tab)
1. Ferrous Fumarate 60mg
2. Iberet 105mg of ferrous sulphate
3. Obimin/ Obimin plus/ 30mg of ferrous fumarate/
New Obimin ferrous sulphate
13. 7. Parenteral Iron Therapy
No advantage over oral iron if the latter is well tolerated
Only indicated in patients who cannot absorb iron, non
compliant or developed serious side effect with oral iron
Preparations: Iron Dextran ( Imferan) –Intramuscularly
Dose: elemental iron needed (mg)=
( desire Hb – patient’s Hb) x weight(kg)x2.21+1000
Example: 60kg patient with Hb 7g/dl
Elemental iron needed for her:
(10-7)x60x2.21+1000= 1398mg
Caution: small risk of hypersensitivity, should only given in
hospital setting. Test dose of 50mg of IM Imferan given
followed by 100mg daily until total dose meet
14. 8. Haemoglobin <11g/dl in patient known to be
alpha or beta thalassemia trait:
a. Prescribe Folic Acid 5mg daily
b. Check serum ferritin
- If serum ferritin < 12 microgram/l, to treat as
concurrent IDA
15. 9. Indications for blood transfusion during
antenatal period:
Hb < 6g/dl
Hb <8g/dl and POA >36/52
Moderate and severe anaemia in patient with
known heart disease or severe respiratory disease
Symptomatic anaemia
Placenta praevia with Hb <10g/dl
Patient who develops severe side effect to both oral
and parenteral iron therapy
16. 10. Anaemic patient in labour:
To transfuse if Hb <8g/dl and transfer to the hospital with
specialist in high risk patient
High risk patient with Hb between 8-10g/dl require at least 2
pint of blood ( GXM) AND transfer to the hospital with
specialist if possible
Patient with risk of PPH and anaemic is best delivered in the
hospital with specialist
In the event of advance labour where transfer is not
possible, specialist input is required regarding the need for
blood transfusion. GXM of at least 2 pint of blood must be
made available in such patient
17. Prophylactically, can start IV infusion of pitocin ( 20
unit in 500ml Hartman’s saline) to run over 4-6 hours
after delivery of the baby
In grandmultipara, to start on 40 unit pitocin in
500mls Hartman’s infusion over 4-6 hours
Close maternal monitoring immediate postnatal
period to be able to diagnose PPH early
18. Antenatal management
Hb < 11g/dl, POA < 28 week
No indication for blood transfusion,
no apparent medical illness
Empirically treat as iron deficiency anaemia
-Investigation : Full blood picture (FBP)
-Tab ferrous fumarate 400mg bd + Folic acid 500mcg od
-Recheck Hb after 4 weeks (Hb expected to rise by 0.3g-1.0g per week)
Review Hb and FBP
19. Microcytic hypocromic anaemia
Not microcytic and but Hb not rises as expected Microcytic hypocromic
hypochromic anaemia but Hb rises as
anaemia expected
Perform following investigation
• Serum ferritin
• Hb electrophoresis -Continue same treatment for
Refer to combined
or antenatal the rest of the pregnancy

Combined/Specialist Deworming/treat
antenatal clinic malaria/address issue of
occult blood loss if indicated
Parenteral iron therapy
( IM Imferon)
20. Antenatal management
