Clotting in the circuit during CRRT can be prevented by attention to circuit preparation with air and bubbles removal and addition of heparin into the circuit with priming, circuit connection to a large Fg vascular access catheter with side by side lumen configuration. Reliable and uninterrupted blood flow is essential to prevent stasis and clotting,, use of a larger surface area membrane in the adult, pre-membrane substitution fluids administration, and keeping the blood level in the venous bubble trap high with post dilution fluid administration. Nursing training and ‘troubleshooting’ ability is also vital to prevent clotting due to delayed alarms correction and aims for skilled use of this technology.
