The Impact of Buttonhole Cannulation on Patients and Staff in Hemodialysis Facilities

The two reasons that patients desire buttonhole cannulation are avoidance of puncture pain and extension of arteriovenous fistula life. Despite the desire to receive buttonhole cannulation by many patients, medical staff at most local hemodialysis facilities tend to hesitate to implement the cannulation method. This method is used on patients in the dialysis unit at Saitama Medical Center, but tends to be discontinued for those patients upon their transfer to local hemodialysis facilities. Medical staff members of one local hemodialysis facility report the percentage of patients on the buttonhole method was 53% in 2007, but that it sharply decreased to 17% in 2013. Hesitation by local hemodialysis facilities to adopt the buttonhole method is due to, but not limited to, several factors. These factors include the frequently occurring trampoline effect, the difficulty of removing scabs, formation of a false buttonhole track, and the pain from insertion of a dull needle. Perceived differences in the value of buttonhole cannulation may potentially affect communication between patients and staff in local hemodialysis facilities.
