How Constant Site Method Was Invented? Serendipity. • In 1972 I had a patient with very short segments suitable for cannulation • By necessity Sister Helena Kubara, the Head nurse of our dialysis center cannulated fistula into the same spots. • After a few months the patient noted that cannulations were not painful. • By the word of mouth other patients requested the same method and I agreed.
Early Development of the Technique • Only one nurse was eligible to develop constant site. It took about 12 sticks. • We used needles made in Seattle Artificial Supply Co (sharper), and Factory in Łódź, Poland (blunter but less expensive) • We e reused needles for the same patients, so they became even blunter with reuse. • By the way, we reused coil dialyzers and lines as well. We were very short of money.
