Management for iron deficiency anaemia
dietary advice - limit milk intake

what protein is dysfunctional in sickle cell anaemia in children?
beta globin chain - causes RBC to deform when deoxygenated
sickle cell crisis =
deformed RBC get stuck
sickle cell crisis triggers
hypoxia cold dehydration excessive exercise infection stress
up to which month is sickle cell not a problem in new borns
6m - foetal hb still in the blood
acute treatment in sickle cell crisis
analgesia
oxygenation
treatment of the associated sepsis
