title: Simultaneous collection of platelets and cryoprecipitate by plasma-exchange donation.
abstract: To increase cost efficiency, the simultaneous collection of platelets during plasma-exchange donation of cryoprecipitate was investigated. Sixteen desmopressin (DDAVP)-stimulated donors underwent 90 simultaneous donations. Permanent donor plasma loss for each donation averaged 150 ml in cryoprecipitate and 151 ml in platelet concentrates. Mean factor VIII (FVIII) yield was 4699 +/- 2754 IU per donation. The mean yield in the platelet products was 4.63 X 10(11) platelets; aggregation properties and posttransfusion increments were satisfactory. White cell contamination averaged 4.05 X 10(9) but could be lowered by a secondary centrifugation. The direct cost for a single-donor platelet transfusion produced in this way is estimated at $102.19 and that for FVIII at $0.055 per IU. Simultaneous donation is technically feasible and safe for donors, and it provides functional products that are more cost-effective than apheresis platelets or cryoprecipitate donated separately.
