Blood transusion: use and abuse of blood components.
Transfusion of whole blood and some blood components may result in serious or fatal complications, among which hepatitis is most frequent (20,000 to 30,000 cases and 3,000 deaths a year). Although hepatitis B virus (HB Ag) sometimes is implicated in posttransfusion hepatitis, non-A non-B. virus(es) (hepatitis "C" virus) probably accounts for most posttransfusion hepatitis. Half of all blood transfusions may be unnecessary.Responsible transfusion practice requires use of appropriate blood components for which there is adequate justification. Transfusion of red blood cells should be given as packed cells in most instances and whole blood should seldom be used.
