Comparative analysis of risk degree of bleeding in patients with different kinds of hematonosis / 中国输血杂志

ABSTRACT

Objective To retrospectively analyze the platelet count and related factors in bleeding patients with hematonosis,and to calculate the risk of bleeding when the platelet count is at each exposure level.Methods Retrospective analysis of patients from Department of Hematology Inpatients in Nanjing Drum Tower Hospital,Nanjing First Hospital and Nanjing Jiangning Hospital from July 2013 to June 2017 was collected.And the risk of bleeding for different hematonosis was calculated.Results The tolerance of the 5 categories of hematonosis to low platelet counts is comparedAA and ITP can tolerate lower levels of platelet count;MDS and AML(except M3) are more prone to bleeding;ALL is the most susceptible to bleeding.Conclusion When platelet resources are scarce,priority should be given to ALL,MDS and AML patients,in order to ensure the safety of critically ill patients.For patients with AA and ITP,the platelet infusion threshold may be reduced appropriately,in oder to reduce the incidence of platelet transfusion refractoriness.
