Summary

The prevalence rate of hemodialysis in Taiwan is the highest in the world, and the number of new cases of hemodialysis and the death rate are gradually increasing every year. Long-term hemodialysis patients must receive dialysis through the arteriovenous fistula. If the arteriovenous fistula is narrowed, the dialysis effect will be poor or the dialysis will not be possible due to blockage, resulting in complications and mortality. The detection of the arteriovenous fistula must rely on the assistance of professionals.

\* Is it easier for clinicians to detect arteriovenous fistula stenosis by an electronic stethoscope?

This study uses an electronic stethoscope to take the hemodialysis center of Douliu District, Yunlin Branch of National Taiwan University Hospital as the experimental site. Select 30 patients who need long-term dialysis, adults (20-99 years old) who have been on dialysis for more than 3 months and have arteriovenous fistula. The experiment period lasted for 3 months, and each person received 2-3 voices per week, about 1080 voices. The main purpose is to use the electronic stethoscope and the experience of traditional professionals, hoping to detect and predict the stenosis in advance. The important key factors of vascular access stenosis in hemodialysis patients were found through regression analysis of the Albumin value and clinical data obtained from routine treatment of patients of a fixed blood test in monthly hemodialysis center.

DEVICE

Detection and Prediction of the stenosis of arteriovenous fistula in hemodialysis patients by an electronic stethoscope

The detection of the arteriovenous fistula must rely on the assistance of professionals by palpation or a conventional stethoscope. This study will investigate the detection and prediction of arteriovenous fistula stenosis in hemodialysis patients by an electronic stethoscope.
