- Perfusão vascular, composição corporal e força muscular de pacientes insuficientes renais crónicos em programa regular de hemodiálisePublication . Bernardino, Bruna; Novo, AndréOBJETIVO: Foi objetivo deste trabalho identificar a relação entre perfusão vascular, composição corporal e força muscular de pacientes insuficientes renais crónicos em programa regular de hemodiálise. MÉTODOS: Foram estudados 27 pacientes, 20 do sexo masculino e 7 do sexo feminino, com a faixa etária entre os 39 e os 94 anos de idade. Avaliou-se ecograficamente o fluxo e o diâmetro da veia de drenagem. Foram ainda realizados o Hand Grip Test e o Pinch Gauge Test©, bem como foi efetuada uma avaliação antropométrica utilizando uma balança de bioimpedância. RESULTADOS: Obteve-se uma média do fluxo da veia de drenagem da fístula arteriovenosa de 1340,10±304,62ml/min e o diâmetro da veia de drenagem da fístula arteriovenosa foi, em média, de 0,57±0,06mm. Para verificar a existência de diferenças significativas entre as variáveis recorreu-se ao teste de coeficiente de correlação de Spearman. Quando se correlaciona a força de preensão digital esquerda e a média do fluxo (r= -0,576, p =0,01), a força de preensão digital lado não fístula e a média do fluxo (r= -0,450, p=0,059) e a gordura visceral e a média do fluxo (r= -0,444, p=0,05) encontram-se correlações negativas estatisticamente significativas. Os indivíduos com mais força de preensão digital esquerda evidenciam menor fluxo, diâmetro e área da veia de drenagem. Os indivíduos com menos fluxo da veia de drenagem também apresentaram mais gordura visceral. CONCLUSÕES: Os resultados encontrados sugerem que há uma relação negativa entre o fluxo da fístula arteriovenosa e a força muscular e a composição corporal, ou seja, para valores mais altos de força muscular e dos parâmetros da composição corporal correspondem valores mais reduzidos do fluxo da fístula arteriovenosa.
- Vascular perfusion, body composition and muscle strength in chronic kidney disease patients on regular hemodialysis programPublication . Bernardino, Bruna; Novo, André; Azevedo, Paulo; Mendes, Eugénia; Preto, LeonelThis 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.
- Vascular perfusion, body composition and muscle strength in chronic kidney disease patients on regular hemodialysis programPublication . Bernardino, Bruna; Novo, André; Azevedo, Pedro; Mendes, Eugénia; Preto, LeonelHemodialysis is a technique that effectively replaces some functions of the human kidney, allowing the survival of such patients, since loss of kidney function is incompatible with life. In most patients with chronic kidney disease, the level of renal function tends to gradually decrease over time. The most serious outcome of chronic kidney disease is renal failure. The vascular access is vital in patients with chronic renal failure undergoing dialysis and their dysfunction is a major cause of morbidity and hospitalization. Adequate vascular access for hemodialysis defines not only a better therapeutic outcome and patient survival. The flow of arteriovenous fistula (AVF) is an important factor in the successful execution of the hemodialysis. Were studied 27 patients, 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. Were also carried out the Hand Grip Test, the Pinch Gauge Test and it was done an anthropometric evaluation using a bioimpedance scale. This study aimed to identify the relationship between vascular perfusion, body composition and muscle strength in chronic kidney disease patients on regular hemodialysis program. The average flow of the arteriovenous fistula was 1340.096±304.615ml/min and the diameter of the arteriovenous fistula was, on average, 0.57±0.06mm. To check for significant differences between the variables we used the Spearman correlation coefficient test. When correlated 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), there were statistically significant negative correlations. Individuals with higher results in the pinch gauge test in left finger showed lower flow, lower diameter and lower area of the draining vein. Taking into account the results obtained, we can see that the sample is relatively small, which means that the conclusions of this study are not extrapolated to the Portuguese population in regular hemodialysis program, but just be confined to the group of patients evaluated. The results suggest that there is a negative relationship between the flow of the arteriovenous fistula and muscle strength and body composition. For higher values of muscle strength correspond lower flow values of the draining vein.
