Definition of ESRD.
Renal replacement therapy serves as a substitute for the kidney’s solute and fluid removal role.
-In the acute setting: CVVH vs. HD can be used.
-In the chronic setting: PD vs. HD can be used.
-Kidney transplantation is an option for patients who qualify.
Indications for Renal replacement therapy.
Hemodialysis access.
Intermittent hemodialysis vs. CRRT
Continuous renal replacement therapy (CRRT)
What’s the difference between CVVH and CRRT? CVVH is a common type of CRRT. But there are other types of CRRT.
“Different continuous modalities include slow continuous ultrafiltration, continuous arteriovenous hemofiltration (CAVH), continuous venovenous hemofiltration (CVVH), continuous venovenous hemodialysis (CVVHD), continuous arteriovenous hemodialysis (CAVHD), and peritoneal dialysis.”
CRRTs are generally most often used when hemodynamic instability precludes the use of intermittent dialysis.
CRRT is a dialysis modality used to treat critically ill patients in the ICU. These patients are so critically ill and on pressor support so that they cannot tolerate the usual dialysis that takes out and cycles a large amount of the patient’s blood in about three hours. Because these patients are hemodynamically unstable, dialysis cannot be done. Instead, CRRT is done and can stay on for 24 hours.

“CVVH was the primary mode used for CRRT at the authors’ institution until 2008, when CVVHDF was introduced and became the primary CRRT mode.”
