Buttonhole Cannulation VS Conventional Cannulation – The Quality Outcome

Buttonhole cannulation is superior in securing hemostasis as compared to conventional cannulation, but not in reducing pain and ease of cannulation. More educational workshops should be conducted to improve the skill

A Comparison of Buttonhole Cannulation versus Conventional Cannulation on Frequency of Infection and Thrombosis

In this study, the frequency of infection and thrombosis were not significantly increased in the buttonhole group but it might be due to small sample size, high dropout rate and short duration of the study. The practice of buttonhole cannulation should be encouraged provided cost is not a factor.
