ROJAS ESTRADA, Julia Janet et al. Hydration state of hemodialysis patients: clinical method versus vena cava inferior method. Rev cubana med [online]. 2010, vol.49, n.4, pp. 363-371. ISSN 1561-302X.

Backgrounds: The overhydration chronic is a cardiovascular mortality in hemodialysis. Objective: To elucidate the dilemma related to the clinical method versus the vena cava inferior method to define the hydration state in hemodialysis patient. Methods: The relation between the relative difference in the vena cava inferior diameter in predialysis and postdialysis exhalation and the percentages of body weight reduction, of the systolic and diastolic blood pressure. The sensitivity and specificity of clinical method was assessed according to the vena cava inferior method. Results: The vena cava inferior method decreased with reduction on body fluid. The clinical method sensitivity according to vena cava inferior method was of 57.1 for a 95 % CI between 46.0 and 68.3 and a specificity of 86.1 for a 95 % CI between 78.0 and 94.0. Conclusions: The clinical method is according the vena cava inferior method one more specific than sensitive.
