Complications of Dialysis Dysequilibrium – Removal of uric acid too quickly Hypovolemia Hypotension/Hypertension Muscle cramps – Removal of fluid too quickly Dysrhythmias Angina

Continuous Renal Replacement Therapies (CRRT) Similar to hemodialysis Removes waste product slowly Requires more time Used when uric acid needs to be aggressively managed

Peritoneal Dialysis The peritoneum is used as the semipermeable membrane Osmosis is used to remove fluid Peritoneal catheter is placed in surgery Used for patients who do not live close to a dialysis center

Chronic Renal Failure Slow, progressive, irreversible Progressive destruction of nephrons Diabetes mellitus and hypertension are the most common causes More common in African Americans, Hispanics, and Native Americans
