Researchers Note Rise Of Dialysis Treatment Following Cardiac And Vascular Surgeries

Researchers recently discovered a rise in the number of post-surgery patients who have developed acute kidney injuries and needed dialysis treatments. The instance of this complication following cardiac and vascular surgery has risen three-fold since 1995, according to a study published in the Canadian Medical Association Journal.

The researchers examined 552,672 patients in Ontario who had undergone elective cardiac or vascular surgery between 1995 and 2009. They found 2,231 of these individuals received acute dialysis in the two weeks following their surgeries. Of these individuals, roughly half died within three months of their surgery and 27 percent of the survivors needed long-term dialysis. The study investigators also noted the rate of acute dialysis treatments increased over time from 0.2 percent in 1995 to 0.6 percent by 2009.

"This study shows an important increase in the complication of severe acute kidney injury treated with dialysis after cardiac and vascular surgeries," writes Dr. Amit Garg of Western University, Lawson Health Research Institute and the Institute for Clinical Evaluative Sciences in Toronto. "Outcomes for patients treated with acute dialysis after surgery remain poor."

Seniors who undergo surgery may require elder care following the procedure in order to monitor their health as they recover.
