| Summary: | Often the only available way of checking the adequacy of HD reaching dry weight after completion of dialysis treatment or monitoring arterial blood pressure. The goal of this paper is to show whether echocardiographic index measuring inspiratory collapse VCI can further assist in assessing the state of hydration of patients on HD. Method: In a study that we conducted on the UDK in Belgrade Centre for HD at 20 toro children on HD (before and after HD) and 20 healthy children, the control group. The M mode echocardiography we measured the diameter of the inferior vena cava (VCI) and calculated the index VCI inspiratory collapse. Also, accompanied by the correlation of these parameters with the dimensions of the left atrium, left ventricular in diastolic and body weight. Results: Children were before HD was significantly higher static diameter VCI and LA diameter compared to the control group (p <0.05). Index is collapsed before the HD was be substantially lower than in the control group (p <0.05). After HD LA diameter was still significantly higher than in the control group (p <0.05), while the other parameters were not statistically be substantially different. Index collapsing VCI differed significantly before and after HD (p <0.05), examining the correlation between VCI and diameter dimensions of the left ventricle during diastole (LVD) found a statistically significant positive correlation between these two parameters in all three groups of measurements (p <0.01). A statistically significant positive linear correlation was found between the VCI diameter and diameter of the left atrium (LA) in all three of measurements (p <0.01). A statistically significant positive linear correlation was found between the diameter of VCI and body weight in children after HD and control groups (p <0.01). CONCLUSION: Index collapsing and VCI in combination with other parameters can further improve the monitoring of the state of hydration and improve the quality of life of patients on hemodialysis.
