Conclusions of the initial study (1) • Insertion into a previously used site is easier and can be done very quickly, in less than ten seconds. • Cannulation is less painful and anesthetic use may be eliminated. • Reinsertions of needles because of "bad sticks" are virtually eliminated.
Conclusions of the initial study (2) • Hematoma formation is reduced more than one hundred times. • The infection rate was slightly, but not significantly, higher than with different site method of needle insertion. • Some patients who were dialyzed more than thrice weekly had two pairs of puncture sites used alternately because insertion at the same site on subsequent days was painful.
