What is the lower limit of Hb when a blood transfusion should be planned in an otherwise normal child and a sick child?
7
Expert Answer :
There is no easy answer for your question` Level of Hb to Tx depends on clinical situation. an acutely dropping Hb in a child with Intravascular Hemolysis in a G6PD deficienct pt requires Tx at higher levels of Hb as there is no time for cardiac compensation` In contrast a child with Chronic IDA does not need Tx even if Hb is 4 gm, dl` but if the same child has pneumonia he needs to be Tx at that level. In adults patients with Myocardial ischaemia will be Txed to bring HCT More than 33 percent. Patients with cardiac hemolyis will require maintaining higher Hb so that the gradient across valve is decreased and hence hemolysis is decreased. There is NO VALUE OF HB at which Transfusion is justified` in individual situations it varies considerably.
