Abstract: ObjectiveTo understand the status of blood component transfusion,infusion volume,rationality and outcomes in the ICU patients. MethodsRetrospective investigation from June to December 2015 was executed in 274 ICU patients who had underwent blood component transfusion,whole blood transfusion and transfusion indications.Laboratory tests and curative effect were analyzed. ResultsOf 274 cases of severe patients with blood transfusions,91.2%（250/274）,87.2%（239/274）,2.6%（7/274）,and 5.8%（16/274） of them received infusion of red blood cells,plasma,cryo,and platelets. The biggest red blood cell transfusion volume was seen in the patients of thoracic surgery,gastrointestinal bleeding,postpartum hemorrhage,accounting for 61.2%（153/250）. 15.3 percent（42/274）and 29.5% （84/274）of patients had RBC transfusion whose Hb was over100 g/L and Hb was between 70~100 g/L,Patients with Hb<of 70 g/L had RBC transfusion rate of 46.4%（127/274）89.1 percent（213/239）of ICU patients presented low PT,APTT and Fib,with an average value of <50×10⁹/L and a rational use of plasma,platelets and cryo. The volume of RBC transfusion was gradually increased with the duration of hospitalization,and no significant association of mortality with the volume of RBC use was noted. ConclusionIn ICU patients,combination of two blood components were frequently used,and the rationality was seen in transfusions of plasma,cryo,and platelets rather than in red blood cells.
