Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1: Routine insertion of Dolphin protect vascular access device for haemofiltration
Arm 2: Routine insertion of Niagara vascular access device for haemofiltration

The Niagara device has large diameter channels, allowing high blood flows, but it occasionally can be difficult to insert as of its shape with a shoulder within the catheter. The Dolphin Gambro catheter has a wedge shape, which might make insertion easier and the catheter is impregnated with an antibacterial material that might reduce the rate of infection.

Survival analysis will be used to examine duration of catheter placement and haemofilter life. Vascular access devices are retained for about seven days on average. Haemofilters generally last 12-36 hours. Therefore several haemofilters may be used for each vascular access device. Haemofiler life may be a surrogate measure of vascular access efficacy.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Before insertion of the vascular device the doctor opens a sealed opaque envelope specifying with device to use and which access site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated randomization
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?
