ANEMIA]

Formula for calculating the required dose of Iron sucrose
2.4 X Pre-pregnancy Weight in Kgs X Hb% deficit{11-actual Hb%} in mgs
Plus
Iron required to replenish the iron stores = 500mg
Prepregnancy Weight = 45 kgs
Actual Hb% = 6 gms%
Then required dose = 2.4 X 45X{11-6}5= 540 + 500 = 1040mgs
OR
Hb% deficit ( 11- Actual Hb%) X 150 + 500
[ 150 as 150 mg of IV Iron is required to raise the Hb% by 1gm%]
Iron required to replenish the iron stores = 500mg
Actual Hb% = 6mgs%
Then required dose = {11-6)={5 X 150}+ 500 = 750 + 500 = 1250 mg%

Adminstration of Iron Sucrose
IV Infusion: upto 200mg in 100ml NS over 30 minutes
Can be given on alternate days up to 3 times a week
Maximum dose at a time is 200mg infused over 30 minutes
All to be given Albendazole 400mg at the beginning of the therapy

Safety of Iron Sucrose
No test dose required
Rarely minor adverse effects like rash, myalgia etc.,
Allergic reactions: 3.3 cases/ millon per year

Iron deficiency anemia develops after normal stores of iron have been depleted in the
body. Thus the signs of anemia may not be clinically visible until the anemia is severe
(Hb less than 7-8 gms/dl). However, adverse impact on health occurs even before this
stage is reached.
