MKCG MEDICAL COLLEGE
BRAHMAPUR, ODISHA; INDIA
 Most Common Nutritional Disorder in the World
 Incidence = 40 to 60 % of pregnant women in India
 Commonest Medical(hematological) disorder during
pregnancy
 25% of direct maternal deaths
 Responsible for 40% of maternal deaths in third
world countries.
 India contributes to 80% of maternal deaths due to
anemia in South Asia
Pregnancy : Most dangerous
journey of mankind
Anemia begins in
childhood, worsens during
adolescence in girls and gets
aggravated during pregnancy
 Quantitative or qualitative reduction of Hb or circulating
RBC’s or both resulting in a reduced oxygen carrying capacity
of blood to organs and tissues
 Woman Hct 33% or Hb 11g/dl – 1st & 3rd trimester and Hct
32% or Hb 10.5 g / dl in 2nd trimester(CDC/WHO)
Gm% ICMR WHO
Mild 10 – 11 10-10.9
Moderate 7 – 10 7-9.9
Severe 4 – 7 <7
Very severe < 4
Physiological
Acquired
Nutritional deficiency anaemias
- Iron deficiency (90%)
- Folate deficiency
- Vit. B12 deficiency
Infections : Malaria/Hookworm/UTI
Hemorrhagic –acute/chronic blood loss
Bone marrow- Aplastic anemia
Renal diseases
Genetic/Haemoglobinopathies:
- SCD
- Thalassaemias
COMMON ANEMIAS IN PREGNANCY
PHYSIOLOGICAL ANEMIA
• Plasma volume 50% (by 34weeks) but RBC mass
only 25%
• Disproportionate increase in plasma vol, RBC vol. and
hemoglobin mass during pregnancy
CRITERIA FOR PHYSIOLOGICAL ANAEMIA
• Hb = 10 gm%
• RBC = 3.2 million/mm3
• PCV = 30%
• Peripheral smear showing normal morphology
of RBC with central pallor
IRON REQUIREMENTS DURING PREGNANCY
Maternal req. of total Iron -1000mg
 500 mg  Maternal Hb. Mass expansion
 300 mg  Fetus & Placenta
 200mg  Shed through gut., urine & skin
 2.5mg /day in early pregnancy
 5.5mg /day from 20 -32 weeks Average 4 mg/ day
 6 – 8 mg/ day after 32 weeks
Increases from 1-2mg in 1st trimester to 6-8 mg in 3rd
trimester
Absorption of iron depends upon
a) Amount of iron in the diet
b) Bioavailability of iron
c) Physiological requirements
Iron sources are two types
1) Haem iron(5%) : hemoglobin and myoglobin from red
meat, poultry and fish
2) Nonhaem iron(95%): fibers, green vegetables

serum iron levels .
b) Reduced stored iron e.g. serum ferritin with normal
hemoglobin
Latent(iron deficient erythropoisis) :
a) Serum iron drops and the TIBC increases without a change
in the hematocrit.
b) Reduced stored and transport iron
c) Increased erythrocyte protoporphyrin concentration
d) Detected by a routine check of the transferrin saturation.
Frank IDA :

CHF, hypoxia, CHF, hypoxia, LSCS
Infection infection
Hb 8 – 10 gm%, confirm BG & cross-matching
Hb <8 gm%, 2 units to be kept ready in OT
MANAGEMENT DURING LABOUR
• Consideration for delivery in well equipped hospital.
• Avoid sympathetic stimulation and hyperventilation;
prevent rightward shift of ODC.
• Supplemented with oxygen therapy
• Prophylactic forceps/Vaccum to cut short 2nd stage
• Decreased blood loss by active management of 3rd
stage of labors.
• Avoid maternal stress, patient can go into CHF.
• PPH should be emergently treated(uterotonics)
ANAETHETIC CONSIDERATIONS
 Pre oxygenation is mandatory with 100% O2
 Oxygen supplementation should be given in peri and
postoperative periods
 Blood arrangements prior to surgery is must
 Airway maintenance to prevent fall of PO2 due to
airway obstruction
 Hyperventilation to be avoided to minimize respiratory
alkalosis
 General/spinal anaesthesia can be given after platelet
count and excluding h/o spontaneous hemorrhage.
MEGALOBLASTIC ANAEMIA
• Incidence – 0.2 – 5 %
• Caused by folic acid deficiency & Vit B12 deficiency
Pathophysiology
 Preg. Causes 20 -30 fold increase in Folate requirement (150-
450 microgram / day ) to meet needs of fetus & placenta.
 Placenta transports folate actively to fetus even if the mother
is deficient.
 Vit.B12 deficiency : Occurs in patients with gastrectomy , ileitis,
ileal resection, pernicious anaemia, intestinal parasites
FOLATE DEFICIENCY ANAEMIA
 Folic acid reduced to DHFA then THFA, used in
nucleic acid synthesis, is required for cell growth &
division.
 So more active tissue reproduction & growth more
dependant on supply of folic acid.
 So bone marrow and epithelial lining are therefore at
particular risk.
 Coexists with IDA
 Folic acid deficiency more likely if
. Woman taking anticonvulsants.
. Multiple pregnancy.
. Hemolytic anemia, thalassemia & cleft palate
Diagnosis :
-Increased MCV ( > 100 fl)
-Peripheral smear : - Macrocytosis, hypochromia
- Hypersegmented neutrophils(> 5 lobes)
- Neutropenia
- Thrombocytopenia
-Low Serum folate level.(<3ng/ ml)
-Low RBC folate (<20 ng/ml)
CLINICAL FEATURES
• Insidious onset, mostly in last trimester
• Anorexia and occasional diarrhea
• Pallor of varying degree
• Ulceration in mouth and tongue
• Glossitis
• Enlarged liver and spleen
• Hemorrhagic patches under the skin and conjunctiva
• Macrocytic Megaloblastic Anemia
• Peripheral neuropathy
• Subacute combined degeneration of the Spinal cord
a) Hb < 10gm%
b) Hypersegmentation of neutrophils
c) Megaloblast, Howell-Jolly bodies
d) MCV > 100 fl
e) MCH > 33pg, but MCHC is Normal
f) Serum Fe is Normal or high, TIBC is low
g) Serum Vit B12 levels < 100 pg /ml
h) Radio active Vit B12 absorption test (Schilling Test)

MEGALOBLASTIC ANEMIA(BM)
TREATMENT
• Replace iron and treat underlying disease.
• Oral route is preferred for replacement.
• Response can be followed by retic. increase in 1-2
weeks (5-7 days)
• Hb response to treatment
– half normal by a month
– returns to normal by 2-4 months
• Replacement therapy is prolonged by 6-12 months to
replenish stores of iron.
• 1000 microgram Parenteral Cyanocobalamin every
wk X 6 weeks
• Prophylactic : All woman of reproductive age should
be given 400mcg of folic acid daily
• Curative : Daily administration of Folic acid 4mg
orally up to at least 4 wks following delivery

- Beta thalassaemia: Major & Minor
• Microcytic haemolytic anaemias
• Reduced synthesis of one or more of polypeptide globin
chains.
• Higher transfusion requirements in pregnancy worsen
haemosiderosis & cardiac failure.

ANAEMIA ASSOC. WITH CHRONIC
INFECTIONS / DISEASE
• Common in developing countries
• Poor response to Haematinics unless primary cause is
treated
• Worm infestations is common ( Diagnosed by stool
examination )
• Urinary tract inf, & asymptomatic bacteriuria in preg.
is assoc. with refractory anaemia
• Chronic renal disorders = due to erythropoietin def.
• Identifying the etiology and treat accordingly
• Deworming with mebendazole/albendazole/levamisole
• Treated with recombinant Erythropoietin for renal
disease.
• ATT to a patients with tuberculosis
• Antibiotics to treat UTI according to sensitivity
TREATMENT
PREVENTION
• Dietary advice and modification(red meat/ poultry/fish)
• Germination and fermentation of cereals and legumes
improve the bioavailability of iron in food
• Green peas/Whole wheat/Green vegetables/Jaggery
• Iron supplementation of adolescent girls & non pregnant
women
• A nutritious diet in a pregnant woman should be
providing about 40 mg elemental iron daily.
• Food fortification
a) Fortification of staple food like wheat flour which is
technically simple(USA)
b) Fortification of curry powder, salt and sugar, dried
and liquid milk(SA)
c) Fortification of infant foods (INDIA)
d) Fortification of complimentary foods (USA)
 Treatment of hookworm Infestation, malaria,TB
 Avoidance of Hypoxia, Acidosis, Infection, Dehydration
Stress , Exercise, Extreme, Temperature
 Avoidance of frequent child birth.
 Supplemented Viamin-C (250-500mg/day) with iron
 Adequate treatment for any infection like UTI
 Early detection of falling Hb level, levels should be
estimated at 1st A/N visit, 30th & finally 36th week
 Mandatory monthly screening for anemia should be
done in all antenatal clinics(especially at booking and at
28 wks with FBC)
 Screening and effective management of obstetric and
systemic problems in all pregnant women
