Buttonhole technique better than area puncture technique on hemostasis and pain associated with needle cannulation.

Background: The buttonhole (constant site) arteriovenous fistulae cannulation technique, in which the inserted needle utilizes exactly the same site and the same angle every dialysis session, offers the advantage of an easier cannulation procedure, less pain associated with cannulation, and fewer complications when compared with the traditional method.

Objective: To compare buttonhole arteriovenous fistula (AVF) cannulation technique with area puncture method on the effect of hemostasis after needle withdrawal and pain during needle puncture.

Material And Method: The duration of hemostasis after needle withdrawal and pain during needle puncture of AVF were prospectively recorded in 21 chronic hemodialysis patients at Siriraj Hospital.
