Hope these will help.
Every dialysis unit SHOULD be familiar with the National Vascular Access Improvement Initiative - More commonly known a "Fistula First"

"...The initial experience with two methods based on almost ten thousand dialyses led to the following conclusions1:
Insertion into a previously-used site is easier and can be done very quickly, in less than 10 seconds.
Cannulation is less painful and anesthetic use may be eliminated.
Reinsertions of needles because of poorly performed sticks are virtually eliminated.
Hematoma formation is reduced more than tenfold.
The infection rate was not significantly higher than with different-site method of needle insertion. ..."

What Is The "Buttonhole" Technique Of Fistula Cannulation And What Are The Advantages?
The buttonhole technique of cannulation involves inserting the needle (or cannula, as in the case of Nocturnal Hemodialysis) through exactly the same hole every time. This makes success of the cannulation predictable, and after a few insertions there is no pain involved. Although cannulating in the same area of the fistula can be a cause for fistula aneurysms, there is some evidence that the "buttonhole" technique involving insertion in exactly the same hole prolongs the life of the fistula. Results over the last three years have been excellent.
