Body Composition Analyzer Assesses The Effect Of Dry Weight On Hemoglobin Levels In Maintenance Hemodialysis Patients

ObjectiveTo study the effect of body weight analyzer on hemoglobin level in maintenance hemodialysis patients,and to analyze the relationship between hemoglobin and age,sex,angiotensin ?,interleukin-6,ferritin,platelet,creatinine value,urea nitrogen,extracellular fluid difference and other related factors.MethodsSixty-three patients with uremia who underwent maintenance hemodialysis in 2018 affiliated to Shenyang Medical College were selected,including 40 males and 23 females.The human body component analyzer is used to measure the extracellular fluid of the patient.All the patients are dialysis,and the urine is evacuated to remove metal objects such as key jewelry.The tester is standing upright,the eyes are straight ahead,the shoes and socks are taken off,and the feet are properly placed.On the foot electrode,straighten the upper limb,hold the hand electrode with both hands,about ten centimeters from the body side,about 300°angle.Keep this position for about 1 minute,and measure the body fat percentage,total body water,protein content,mineral content,fat-free body weight,muscle weight,and intracellular and extracellular fluids of the subject,and then re-evaluate the dry weight based on the results.The patient was gradually adjusted to the target dry weight level during the month,and erythropoietin and iron drugs were not adjusted for the past 1 month.Subjects were enrolled in venous blood samples for hemoglobin,age,sex,angiotensin?,interleukin-6,ferritin,platelets,creatinine,and urea nitrogen.After 1 month,repeat the blood test to adjust the data to the target dry weight patients.Statistical analysis was performed with SPSS 22.0 software,and the self-control T test was used.P<0.05 was considered statistically significant.Pearson correlation analysis was used to analyze the correlation between hemoglobin value and dry weight,angiotensin ?,interleukin-6,ferritin,platelet,creatinine value,urea nitrogen and other factors.Finally,multiple linear regression analysis was performed.Result1.The average hemoglobin level of patients before dry weight adjustment was 104.78±15.06g/L,and the average hemoglobin level of the adjusted patients was 116.81±13.80g/L,P<0.05.The difference was statistically significant.The original weight of the patient was 62.56±12.61kg,the adjusted average patient weight was 60.83±12.98kg,P<0.05,the difference was statistically significant.Before adjusting dry weight,Ang? was 97.08±19.49,and adjusted to 101.48±18.70,P<0.05,which was statistically significant.2.In Pearson correlation analysis,63 patients had hemoglobin levels and age(years),dialysis age(months),IL-6(pg/ml),platelets(109/L),creatinine values(umol/L),Ang?(pg/ml),ferritin(ug/L),urea nitrogen(mmol/L),extracellular fluid difference(L)and other correlation analysis,including hemoglobin level and angiotensin ?(R=0.378,P=0.002).There was a linear positive correlation with the extracellular fluid difference(R=-0.466,P<0.001),and the difference was statistically significant(P<0.05).3.Multiple linear regression analysis showed that hemoglobin was linearly positively correlated with angiotensin ?(Tr=3.321,P=0.002),with,extracellular fluid difference(T=-3.808,P<0.001)showed a linear negative correlation(P<0.05),the difference was statistically significant;with age,dialysis age,platelet count,creatinine value,ferritin(ug/L),urea nitrogen(mmol/L),IL-6(pg/ml),There was no correlation(P>0.05).ConclusionThe body composition analyzer was used to evaluate the extracellular fluid content of maintenance hemodialysis patients,and the dry weight of maintenance hemodialysis patients was reassessed.After one month,hemoglobin increased before the adjusted dry weight,and hemoglobin level was linearly positively correlated with angiotensin ?.There was a linear negative correlation with the difference in extracellular fluid.
