Abstract

This study investigated the effect of needle bevel position during arteriovenous fistula cannulation on bleeding stop time in patients with chronic hemodialysis. An arteriovenous fistula puncture was performed on patients using the needle bevel up and down and the bleeding stop time was recorded in minutes. The outcomes of the two techniques were compared. The anticoagulant type used did not affect the bleeding stop time in the 55 patients with hemodialysis included in this study. On separately considering puncture outcomes and anticoagulant type used, the bleeding stop time in both arterial and venous needle bevel down punctures was found to be significantly lower compared with the bevel up puncture (p
