Dialysis Patients Face Increased Infection Risk from Catheters, Study Claims Dialysis catheters used to provide a pathway to a patient's blood have been tied to a greater infection, cardiovascular problems, and mortality risk than other forms of procedures that access a patient's blood supply in dialysis treatment, a new study finds. A team of nephrology experts, whose study results were published in the Journal of the American Society of Nephrology February edition, reportedly
looked at the possible link that ties three hemodialysis access to the risk for infections, heart problems, and even death in people with kidney disease or renal failure. Hemodialysis, the most commonly used type of dialysis in patients with advanced and permanent kidney failure, involves the use of a machine that carries away and returns a patientâ€™s blood, artificially ridding the body of waste, salt, water and other impurities, nephrology experts say. In commencing a dialysis treatment, an access point to patient's blood must be created using arteriovenous fistula â€“ an access made by surgically connecting a vein to a nearby artery, usually in the arm, arteriovenous graft -- an artificial tube surgically placed between an artery and a vein in either the arm or the leg, or a central venous catheter â€“ a tube made of soft plastic usually placed in a large vein in the chest or neck.
After having reviewed 67 previously conducted studies involving 586,337 hemodialysis patients, the research team found that patients using catheters showed a greater risk for major cardiovascular events by 38 percent, fatality risk by 53 percent, and more than double the risk of developing potentially fatal infections. Patients who have been using grafts reportedly had a 36 percent greater risk for fatal infections, and 18 percent increased risk of dying, than participants with fistulas. While more studies may be needed to further assess the safety of these three hemodialysis vascular access procedures, the group of experts concluded the study suggesting that catheters have the highest risks for serious infections, heart problems, and deaths, while fistulas yield the least risk, assuming that the participants were of similar medical state. On the other hand, the group also
noted that the participants were not of similar health, most of those who were on catheters were in a more serious state than patients using fistulas. Furthermore, kidney disease or renal failure patients receiving hemodialysis may also be held vulnerable to unanticipated cardiovascular problem that may potentially stem from certain dialysis medications used alongside a dialysis machine and other substances, online sources say. Such medications, including GranuFlo, have been reportedly linked to a string of adverse effects, including cardiac arrest and even death in large number of patients, reportedly leading to GranuFlo lawsuits in the United States.
