Preoperative Risk Assessment and Management in Adults Receiving Maintenance Dialysis and Those With Earlier Stages of CKD.

With an increasingly aging population and improved mortality in individuals with end-stage kidney disease, more surgeries are being performed on patients with all stages of chronic kidney disease (CKD). This high-risk population carries unique risk factors that have been associated with increased adverse perioperative outcomes, including acute kidney injury, cardiovascular events, and mortality. In this article, we review the literature describing absolute risks associated with common surgeries performed in patients with CKD and patients receiving maintenance dialysis. We also review perioperative optimization with special risk assessment including evaluation of cardiovascular and bleeding risk evaluation, hypertension management, and timing of dialysis. Predictive model scores are reviewed as a method to stratify risk for acute kidney injury, major adverse cardiac events, or other serious complications with elective surgeries. A multidisciplinary approach with individualized counseling is necessary to counsel the patient with advanced CKD or patients treated with maintenance dialysis considering elective surgery.
