ANZCTR - Registration

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

Eligibility

Key inclusion criteria

* The patient is on noradrenaline infusion for haemodynamic support
* The patient was commenced on noradrenaline or haemofiltration within the last 12 hours
* The clinician is uncertain about the balance of benefits and risks likely to be conferred by treatment with different membranes
* The treating clinicians anticipate treating the patient with haemofiltration for at least 72 hours
* Informed consent has been obtained
* The patient fulfils ONE of the following clinical criteria for initiating haemofiltration:
* Oliguria (urine output < 100 ml/6 hr) that has been unresponsive to fluid resuscitation measures.
* Hyperkalemia ([K+] > 6.5 mmol/L)
* Severe acidemia (pH < 7.2)
* Urea > 25 mmol/liter
* Creatinine > 300 mmol/L
* Clinically significant organ oedema in the setting of ARF (e.g., lung)

Summary

Brief summary

This trial aims to study the effect of combining continuous and a new polyamide membrane with larger pores in the treatment of critically ill patients with acute renal failure and low blood pressure (shock) requiring noradrenaline. The investigators wish to compare the clinical effect of this new therapy to that of haemofiltration with a standard membrane.
