Why might a patient prefer to insert needles in the same place on her AVG?

Choosing to insert needles in the same place on an arteriovenous graft (AVG) might stem from the perception of reduced pain at those specific sites. When a patient finds a location where the tissue may be less sensitive or where they have had positive experiences with minimal discomfort, they may prefer to return to that site for needle insertion. Repeated access at the same site can lead to increased familiarity and a sense of control for the patient, ultimately leading to a less stressful experience during dialysis treatments.

Additionally, maintaining a consistent insertion site can help in reducing the likelihood of trauma or repeated use of non-optimal sites that may be more painful. Patients often develop their preferences based on past experiences, which contribute to their decision-making regarding access sites.
