What is a common complication of dialysis that involves the access site?

Infection is a common complication associated with the access site in dialysis patients, primarily due to the need for frequent vascular access. The entry points, such as fistulas, grafts, or catheters, can become infected if proper aseptic techniques are not maintained during the cannulation process or if the site is not cared for correctly afterward. Bacterial entry can lead to local infection, sepsis, or more severe complications, making it crucial for healthcare providers to monitor access sites closely for any signs of infection, such as redness, swelling, warmth, or purulent discharge.

Other complications listed, like air embolism, hypotension, and cardiac arrest, are less directly related to the access site. Air embolism can occur if air enters the circulation during the procedure, hypotension can result from fluid shifts during dialysis, and cardiac arrest can occur due to various underlying patient conditions or complications, but these are not primarily linked to the dialysis access site itself.
