Secondary study design	Randomised controlled trial
Scientific title	AN69 surface treated (ST) versus AN69 in continuous renal replacement therapy (CRRT): a prospective randomized cross-over study without heparin in the extracorporeal circuit
Study objectives	Evaluation of heparin-free treatment
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Continuous renal replacement therapy (CRRT)
Intervention	Please note that the first patient was recruited to this trial in November 2005 and the last patient completed the study in June 2007. Each patient will be treated by maximum 4 filters (surface treated [ST] and non ST). Randomisation of the sequence of treatment.
Intervention type	Other
Primary outcome measure(s)	The primary endpoint is filter lifespan, defined as the time period between patients connection and filter disconnection. Filter clotting will be detected by following transmembrane pressure (TMP) and Filter Pressure Drop (FPD). If the pressure changes are only temporary, treatment is continued. If they are permanent, the filter is discontinued with blood return.
Key secondary outcome measure(s)	Follow up of treatment safety: thrombopenia, bleeding episodes, transfusion requirement, treatment instability due to frequent filter changes.
Completion date	26/09/2006

Participant type(s)	Patient
Age group	Adult
Lower age limit	18 Years
Sex	All
Target sample size at registration	40
Total final enrolment	39
Key inclusion criteria	1. Patients requiring CRRT 2. Patients aged 18 and over 3. Patients weighing 30-120 kg 4. Patients having signed a written consent (informed consent) to participate in the study or, in case the patient is unable to understand and/or sign the consent form, written consent from a relative or, failing which, a person of trust
Key exclusion criteria	1. Suspicion of heparin-induced thrombocytopenia 2. Pregnancy 3. Patients requiring therapeutic anticoagulation for other indications e.g. valvular surgery or extracorporeal ventricular assist devices 4. Patients under guardianship 5. Patients anticipated to require transportation outside the unit for diagnostic or therapeutic procedures in the coming first week. These patients can eventually be included in a later more stable phase. 6. Current enrolment in another trial which could impact the successful completion of this study 7. Unconscious patients for whom no relative or person of trust can give consent for treatment. In the absence of any relative or person of trust, the patient in question cannot be included in the study.
