Evaluation Of Volume Management Of Hemodialysis Patients By Body Component Monitor

ObjectiveBy bioelectrical impedance Body Composition analyzer(Body Composition Monitor,BCM)and general health quality of life table(SF-36)understanding of maintenance hemodialysis patients with capacity management present situation and different capacity state of hemodialysis patients quality of life,to explore the BCM in guiding the limitation of the capacity management,summarized suitable for capacity is assessed using BCM population characteristics.MethodsIn the first part of the experiment,the maintenance hemodialysis patients in the dialysis center of our hospital were selected to collect their predialysis blood pressure,improve BCM to understand the volume status,and score their sf-36 to explore the relationship between volume status,blood pressure and quality of life.The second part of the experiment were retrospectively analyzed 85 patients with maintenance hemodialysis,collect the BCM measurement before dialysis water load value(OH),the day before dialysis ultrafiltration volume,through and through blood pressure,blood biochemical results,three months after the primary disease,complications,such as data,comparison of BCM value measured water load and ultrafiltration volume when times are consistent,the results are inconsistent.Results1、The predialysis blood pressure compliance rate of maintenance hemodialysis patients in the dialysis center of our hospital was 34.3%,and there was no significant difference in the compliance rate of blood pressure control among patients with different OH values(P = 0.655).2、 The rank-sum test was used to compare the differences in sf-36 scores of patients with different OH values.The total scores of sf-36,VT and RE in the OH > 1group were higher than those in the OH 1 group(P < 0.001,P < 0.001,P = 0.033).The SF score of the OH > group was lower than that of the OH 1 group(P = 0.001),and the difference was statistically significant.3、According to the paired design rank sum test,the OH value measured by the human body composition analyzer is not consistent with the actual clinical ultrafiltration amount,with an average difference of 0.70 kg.4、 Body mass index(r=-0.250,P=0.021),fat(r=-0.319,P=0.003),hemoglobin(r=-0.229,P=0.035),albumin(r=-0.339,P=0.002),proalbumin(r=-0.344,P=0.001),transferrin saturation(r=-0.257,P=0.018),ferritin(r=-0.355,P=0.001)and parathyroid hormone(r=-0.336,P=0.002)were negatively correlated with "difference",and the correlation coefficient was statistically significant(P < 0.05).5、After the linear regression equation was established,the appropriate regression model(R2=0.501,F=3.847,P<0.001)was finally obtained(three index data).For each unit increase in ferritin,the "difference value" would decrease by 0.281 L on average.For each unit increase in proalbumin,the "difference" decreased by an average of0.283 L.For each additional unit of fat,the difference decreased by an average of0.229 L.ConclusionEven clinical evaluation has reached the dry weight of maintenance hemodialysis patients,by BCM measured OH value and clinical practical ultrafiltration volume differences still exist many patients after dialysis treatment capacity load,but this part of the patients quality of life score higher,better mental state,that they did not feel discomfort or negative emotions,because the capacity load hints capacity load conditions are likely to be higher comfort level for some patients,completely depend on the guidance of BCM capacity management is not reliable.The higher the level of body mass index(bmi),especially high fat levels,hemoglobin and albumin level before standard patients,BCM measured OH value and clinical practical ultrafiltration volume difference is smaller,the BCM is more applicable in the capacity management of this kind of crowd,and the lower the index of patients,correct nutrition,enhance the level of haemoglobin,such as or more important,slow adjust ultrafiltration volume should be cautious.
