Diagnostic Considerations

Important considerations

Use of a blood product (eg, albumin) in an exchange transfusion may result in the transmission of infection. Infections related to blood products can be avoided by using normal saline, which is sterile and which has been shown to be as effective as albumin.

Informed consent must be obtained as exchange transfusions have multiple risks (see Treatment).

Umbilical partial exchange transfusion increases risk of necrotizing enterocolitis (NEC), especially if colloid is used.

No improvement in neurologic outcomes has been reported with partial exchange transfusion. However, polycythemia and neurologic abnormalities have been linked. Because of this, a symptomatic infant who has not been treated with partial exchange transfusion, and who subsequently develops neurologic abnormalities, may be considered inadequately treated.

Other problems to be considered

Method of blood draw

Capillary hematocrit (Hct) measurements depend on regional blood flow and can widely vary from central venous measurements, generally overestimating the central or true Hct level.

Iatrogenic problems

These may be related to transfusion or practice of delayed cord clamping.
