Continuous Renal Replacement Therapy (CRRT)

_______________ are used to prevent clotting; they can be used infused as a bolus at the initiation of CRRT or through an infusion port before the hemofilter.

anticoagulants

_______________ is a method used for treating AKI; it can also be used in conjunction with HD.

Continuous Renal Replacement Therapy (CRRT)

Removes both fluids and solutes. Requires both dialysate and replacement fluid.

Continuous Venovenous Hemodialysis (CVVHD) and Continuous Venovenous Hemodiafiltration (CVVHDF)

Removes both fluid and solutes. Replacement fluid needed

Continuous Venovenous Hemofiltration (CVVH)

Treatment is continuous can last up to 24hrs to weeks Solute removal can occur by convection in addition to osmosis and diffusion without dialysate It causes less hemodynamic instability (hypotension) Does not need specialized personnel and can be monitored by ICU Nurse Requires less Equipment then HD; only a blood pump

Features of CRRT in comparison to HD

Obtain weight Obtain Serum Lab Values VS q hour I & O's Maintain Patency of CRRT System Assess site for infection

Nursing Considerations for CRRT

Simplified version of CVVH. Removes fluid only. No fluid replacement needed.

Slow Continuous Ultrafiltration (SCUF)

CRRT can be continued for as long as 30-40 days, but _____________ should be changed every 24-48 hours to prevent filtration loss efficiency and potential for clotting.

hemofilter

Vascular Access Sites for CRRT are through the ____________ or ____________ vein with a ____________ ___________ _________.

juglar, femoral, double-lumen catheter

CRRT is contraindicated in patients that have _______________________ manefistations of uremia. (hyperkalemia, perircarditis)

life-threatening

CRRT can also replace ____________ with replacement fluid for solutes such as sodium, chloride, bicarbonate, and glucose.

solutes

Ultrafiltrate for CRRT should be ___________ in color with not blood tinge; otherwise suspect membrane rupture or bleed.

yellow
