Red cells, frozen in the presence of glycerol, can be stored for years at -80C with excellent post-thaw recovery and in vivo survival. In addition to the benefits of long-term storage, the extensive washing associated with deglycerolizing removes essentially all platelets, plasma, microaggregates of cells and cell debris and there is some evidence of a reduction in the incidence of post-transfusion hepatitis. The majority of the white cells are lost during the processing. Three deglycerolizing methods, based on the Haemonetics Cell Washer, the IBM Cell Processor and the Fenwal Elutramatic, have been evaluated and data on comparative performance and costs are provided. The experience of the Red Cross Blood Program in processing over 90,000 units of frozen red cells is summarized.

In the postwar years the Swiss Red Cross set up and developed a blood transfusion service based on strictly nonremunerated donation. It comprises the Blood Transfusion Service Central Laboratory foundation in Berne and the Swiss Red Cross Regional Blood Transfusion Centres association. The Central Laboratory's responsibilities cover provision of stable blood plasma products and transfusion equipment and the organization of extensive services in the entire field of transfusion medicine. The Regional Centres supply the country with labile cellular blood preparations. The growth of this organization over the last 50 years is described.
Nurses are at the heart of many Red Cross services. Their expertise is recognized and often sought throughout the organization. Nurses can, through active participation and personal donation, assist the agency in reaching its humanitarian goals. The resources, services, and assistance available through the Red Cross give the busy emergency nurses more options in meeting the needs of patients. Nurses in turn can be a resource for the Red Cross. The strength, support, and commitment of dedicated volunteers give meaning to the endeavors of the American Red Cross.
The International Committee of the Red Cross (ICRC) is at the forefront in the provision of surgical care to the victims of war. In 1990 twenty-two surgical teams were deployed in 14 hospitals in eight countries and 18,450 patients were treated. This article reviews the contribution made by ICRC, and the experience that can be gained by New Zealand and Australian surgeons and anaesthetists.
In 1970, the League of Red Cross Societies drew up a plan for the training of delegates in international relief work. The main tasks of the delegates can be divided into: 1) disaster relief, 2) war-time relief work, 3) assistance in organising national Red Cross societies. Special training of certain categories, e. g. doctors, is now being considered. In many relief operations it would be of value to have a doctor as an administrative delegate. It should be easier for the doctor than for a non-medically trained person to decide where and when medical aid should be administered.

The Canadian Red Cross Blood Services have been harvesting plasma from whole blood by plasmapheresis procedure for the last 10 years. To date, we have performed approximately 230,000 procedures. To determine whether this procedure is a health hazard to an individual, a donor safety program was established in 1979 at the National Reference Laboratory. Serum levels of total protein, albumin, and immunoglobulins are monitored at intervals set by the Bureau of Biologics, Health and Welfare Canada. In this communication, we present a 10-year evaluation of this program. A comparison of the protein concentration distributions between first-time and long-term plasmapheresis donors showed no significant differences. Therefore, we have demonstrated that the donors are not at risk as the result of changes in the measured plasma protein levels following plasmapheresis procedure as performed over the last 10 years at The Canadian Red Cross Blood Services.
The hospitals of the International Committee of the Red Cross are often faced with situations in which the number of war wounded requiring surgical attention overwhelms the available facilities. Hospital organization, equipment and changes of attitude necessary for health professionals are considered with respect to triage. Practical aspects of assessment and categorization of the wounded are considered in the light of a large experience; relocation and reassessment of those who do not warrant immediate surgery benefit patients and hospital staff alike. The importance of adherence to an emergency plan and respect for the decisions of the person in charge of the triage are emphasized. The difficult and stressful nature of triage of war wounded should always be taken into account.
Between 1981 and 1990, the American Red Cross Rare Donor Registry supplied 9,872 units of red cell components with rare phenotypes to blood centers in the United States and abroad. Approximately 51% were from donors with high-frequency antigen-negative phenotypes and 49% were from donors with multiple antigen-negative phenotypes. Since 1989, the disease category requiring the largest number of units has been sickle cell disease. Strategies to ensure that the Registry will have adequate resources to meet future requirements include testing selected donors for rare phenotypes and blood conservation programs, such as intraoperative salvage and the treatment of anemia of chronic renal failure with recombinant erythropoietin.
