Vascular perfusion, body composition and muscle strength in chronic kidney disease patients on regular hemodialysis program
| Resumo: | This study aimed to identify the relationship between vascular perfusion, body composition and muscle strength in chronic kidney disease patients on regular hemodialysis program. Method: 27 patients were studied, 20 males and 7 females, with ages between 39 and 94 years old. The diameter and the flow of the draining vein were evaluated by ultrasound flow. A Hand Grip Test, Pinch Gauge Test and an anthropometric evaluation using a bioimpedance scale were done. Results: The average flow of the arterio-venous fistula was 1,340.096±304.615 ml/min and the diameter of the arterio-venous fistula was, on average, 0.57±0.06 mm. To check for significant differences between the variables the Spearman correlation coefficient test we used. There were statistically significant negative correlations between left handgrip strength and average flow (r=–0.576, p=0.01), pinch gauge test of the opposite side of the fistula and average flow (r=–0.450, p=0.059) and visceral fat and average flow (r=–0.444, p=0.05). Individuals with higher results in the pinch gauge test of the left finger showed lower flow, lower diameter and lower area of the draining vein. Conclusions: The results suggest that there may be a negative relationship between the flow of the arteriovenous fistula and muscle strength and body composition. Higher values of muscle strength correspond to lower flow values of the draining vein. |
