Abstract:
Objective To investigate the clinical significance of body composition monitor (BCM) in evaluating the dry weight of hemodialysis patients.Methods Fifty-four hemodialysis patients who reached the dry weight according to clinical assessment were enrolled.The volume load was measured with BCM,and the pre-dialysis blood pressure,plasma B type natriuretic peptide (BNP) and echocardiogram parameters were recorded.Results BCM results showed that,in 54 hemodialysis patients,15 patients presented overhydration and 13 patients underhydration.According to the results of BCM,all of the 15 overhydration patients and some of the 13 underhydration patients adjusted their dry weight.According to the BCM results and the pre-dialysis blood pressure,the patients were divided into 4 groups:group A (without overhydration,the pre-dialysis blood pressure ＜ 150 mmHg,1 mmHg =0.133 kPa),23 cases;group B (without overhydration,pre-dialysis blood pressure ≥ 150 mmHg),16 cases;group C (overhydration,pre-dialysis blood pressure ＜ 150 mmHg),7 cases;and group D (overhydration,pre-dialysis blood pressure ≥ 150 mmHg),8 cases.There were no significant differences in pre-dialysis,plasma BNP and the echocardiographic parameters among the 4 groups (P ＞ 0.05).Conclusions BCM is a simple and convenient tool to evaluate the volume status of hemodialysis patients,It can give guidance of dry weight regulation.Compared with the other clinical assessment methods such as pedal edema,the blood pressure and plasma BNP,it is more accurate and practical.
