INTRODUCTION: The absence of clinical clue of volume excess does not exclude of hypervolemia. The aim of study was to evaluate the value of bioelectrical impedance analysis (BIA) for detection subclinical hypervolemia in peritoneal dialysis (PD) patients.
PATIENTS and METHODS: Twenty six PD patients (F:13, M:13; mean age: 43,88±2,92) in stable clinical condition and at least six months on PD participated in the study. None of the patients had any clinical sign of hypervolemia. Vena cava inferior diameter (VCD) and BIA mesaurements were performed simultaneously after drainage of peritoneal fluid...
RESULTS: Seven of 26 patients have VCD higher than llmm/m2 and 12 patients have more TBW than upper limit of expected range. All of the patients with high VCD also have high TBW. The patients with high VCD have significantly higher TBW than the patients with normal VCD (67,257±1, 263% vs. 58,232±1, 907% of body weights, p<0.01).
CONCLUIONS: TBW mesaurement with BIA is very sensitive and easy test for detection of hypervolemia in PD patients. But minor excess of TBW should be confirmed with other methods such as VCD mesaurement.
