Abstract: Objective To provide a basis for further study on platelet transfusion in patients with liver diseases. The status of platelet application was investigated in the liver special hospital. Methods Clinical and platelets transfusion data were collected for all patients who were transfused with aphaeresis platelet from Jan to Mar,2015.The indications,dosage,and effect of platelet transfusion were statistically analyzed. Results The primary diseases in platelets transfusion were liver cirrhosis and liver cancer in the hospital. Prophylactic transfusion was the main reason for platelets use,which accounted for 86.5 percent. 30.75% of platelets transfusion were performed for improving blood coagulation before intervention.Unexpectedly,infusions for treatment only accounted for 20.31%. The threshold of platelet transfusion mostly was （10~40）×10⁹/L. The effect of platelet transfusion was not associated with cirrhosis progress. Conclusion It's suggested that the indication and dosage of prophylactic platelets transfusion should be optimized in the patients with hepatic diseases.
