A comparative study on curative effect of transfusion of freezing platelets and fresh apheresis platelets

Objective To explore the clinical effect of transfusion of frozen apheresis platelets in order to make up the deficiency of fresh apheresis platelets during the emergency rescue.Methods Patients were randomly allocated into two groups receiving transfusion of fresh or frozen apheresis platelets.The clinical efficacy and increment of platelet count before and after transfusion of apheresis platelets were compared between these two groups.Results After transfusion of platelets,the clinical efficacy and increment of platelet count were raised in these two groups,and their difference was significant(P0.05).In 564 cases,the increment of platelet count after transfusion of fresh apheresis platelets was much higher than that with frozen apheresis platelets,and the difference between these two groups was significant(P0.05).Conclusion The transfusion of fresh or frozen apheresis platelets can control and prevent the bleeding and increase the number of platelet count.Although the efficacy of fresh apheresis platelets is better than that of frozen apheresis platelets,but transfusion of frozen apheresis platelets can replace fresh apheresis platelets in rescue of critically ill patients.
