objective:To explore the value of automated hematology analyser XE-2100 in determining the changes of blood capacity of patients treated with hemodialysis by analyzing the patients'artery blood hematocrits.Methods:hematocrits of the blood from the artery end of dialytic pipeline 60 cases of patients suffering chronic renal exhaustion and being kept with hemodialysis,were analysed 5 times in the procession of hemodialysis,and the descendant ratios of blood capacity(BV)were calculated according to the varieties of hematocrits .Simultaneously,the varieties of blood pressure were monitored,in order that the appropriate dry body weight and dialytic velocities would be determined.Results:Hematocrits of 14 cases rised greatly and blood capacities exceeded the permissible arrange (15%),as a result,the descents of systolic pressure exceeded 30mmHg,and part of patients appeared the symptom of low blood pressure.Among another 46 cases,the hematocries rised appropriately and the blood capacities were normal (15%).The descents of systolic pressure were lower than 30mmHg,and there were no symptom of low blood pressure.Conclusion:it's necessary to calculate the dialytic blood capacities by analyzing the hematocrits with in definite time to control the varieties of the blood capacities (lower than 15%),the occurrence of low blood pressure can be reduced.
