Pain Perception by the Chronic Renal Patient at the Time of Vascular Access Cannulation.

Pain in patients under hemodialysis affects chronic renal patients' quality of life. Distraction has been effective in controlling pain induced by the insertion of needles. Once applied adequately, distraction promotes endorphins' release, with efficacy in acute pain. This study aims to evaluate pain perception while puncturing the hemodialysis device using an anti-stress ball as a distraction strategy.
