Trial Review

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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Angiotensin II
Treatment: Drugs - Saline placebo

Active comparator: Angiotensin II -

Placebo comparator: Placebo -


Treatment: Drugs: Angiotensin II
Angiotensin II will be given by continuous infusion for 24 hours starting at a dose of 5ng/kg/min and then titrated to a maximum dose of 15 ng/kg/min according to a blood pressure based protocol

Treatment: Drugs: Saline placebo
Saline placebo will be given by continuous infusion according to a blood-pressure base protocol. This protocol will also incorporate noradrenaline for blood pressure control (as is true in the active drug arm), such that blood pressure targets will be rapidly achieved in both arms of the study; the only difference being that in the active drug arm, at least part of the pressor effect will be provided by angiotensin II.

Summary
Brief summary
The purpose of this study is to determine the effect of a systemic infusion of angiotensin II on haemodynamics and urine output in critically ill patients with severe sepsis/septic shock and acute renal failure.

It will also help determine the feasibility of conducting a definitive and adequately powered randomised controlled trial of angiotensin II in such patients that would assess mortality and need for renal replacement therapy as endpoints.
