Malcolm Needs ☆ Posted March 30, 2010 Share Posted March 30, 2010 Given a standard volume for exchange, what is the ratio of red cells to plasma, 50/50?VHSurely, it depends upon the circumstances? Are you talking about an exchange transfusion at birth for HDN, or an exchange transfusion in a child or adult with, for example, sickle cell disease?:confused::confused: Link to comment Share on other sites More sharing options...

JOANBALONE Posted March 30, 2010 Share Posted March 30, 2010 We require the MD to request an hematocrit. It may differ for an adult, child or neonate. Link to comment Share on other sites More sharing options...
dmpollock Posted March 30, 2010 Share Posted March 30, 2010 I have attached an abbreviated version of a procedure for preparing reconstituted whole blood for exchange transfusion for infants or for sickle cell patients.The calculations are slightly different than some references, but they yield more accurate results when you are trying to achieve a specific hematocrit. The formula is based on trial and error and actual measurements of specific gravity, donor bags, etc.rwb.pdf Link to comment Share on other sites More sharing options...
