Early failure of arteriovenous fistula and its related factors and nursing / 中国实用护理杂志

ABSTRACT

Objective The aim of the study was to investigate the early failure of newly created arteriovenous fistula(AVF) in patients on maintenance hemodialysis and the factors responsible for the failure. Methods The clinical data were retrospectively reviewed, preoperative examination and laboratory biochemical indicators of 88 patients with newly created AVF for maintenance hemodialysis in our hospital through Hospital Management Information System and telephone follow-ups. Binary Logistic regression was used to analyze the protective factors for early failure. Results In 88 patients, early failure of the AVF was found in 15 patients. Twenty-three factors, including gender, were involved in statistical analysis. There were statistical differences between the two groups in hypertension (χ2=7.689, P=0.006) and whether they had early referral to nephrologists (χ2=5.334, P=0.021). Further regression analysis showed hypertension ( OR=0.192, 95% CI=0.0538-0.692, P=0.012) was protective factor and without early referral ( OR=3.651, 95% CI=1.068-18.302, P=0.039) was the risk factor of early failure. Conclusion This study shows that no early referral and combined hypertension is an important factor affecting the early failure, emphasizing the clinical work, for the diagnosis of patients with chronic kidney disease, early nephrological referral should be established, and blood pressure monitoring should be done to help reduce the incidence of complications.
