Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

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
Intensive Care patients meeting a predetermined criteria to receive a fluid bolus will be randomised into intervention (warmed) or control (room temperature) groups.

Patients in intervention group will receive a 500ml bolus of 4% albumin intravenously over 15 minutes, given through a fluid warmer at 38 degrees Celsius.
Intervention code [1] 301893 0
Treatment: Other
Comparator / control treatment
Intensive Care patients meeting a predetermined criteria to receive a fluid bolus will be randomised into intervention (warmed to 38 degrees Celsius) or control (room temperature 23 degrees Celsius) groups.

Patients in control group will receive a 500ml bolus of 4% albumin intravenously over 15 minutes, given at room temperature.
Control group
Active

Outcomes
Primary outcome [1] 307024 0
To measure the difference in change in stroke volume via transthoracic echocardiogaphy following room temperature vs warmed fluid bolus
Timepoint [1] 307024 0
30 minutely from administration of fluid bolus, for 2 hours.
Secondary outcome [1] 350412 0
Stroke work as calculated by stroke volume multiplied by central aortic pressure

Stroke volume will be measured by echocardiography. Central aortic pressure will be calculated indirectly using radial arterial waveform.
Timepoint [1] 350412 0
30 minutely for 2 hours from initiation of fluid bolus
Secondary outcome [2] 350414 0
Systemic vascular resistance. Calculated from echocardiographically measured cardiac output, mean arterial pressure and central venous pressure.
Timepoint [2] 350414 0
30 minutely for 2 hours from initiation of fluid bolus
Secondary outcome [3] 350415 0
Heart rate as measured by ECG, pulse oximeter and arterial blood pressure monitor.
Timepoint [3] 350415 0
30 minutely for 2 hours from initiation of fluid bolus
Secondary outcome [4] 350416 0
Mean arterial pressure as measured by arterial line.
Timepoint [4] 350416 0
30 minutely for 2 hours from initiation of fluid bolus
Secondary outcome [5] 350417 0
body temperature as measured by temperature probe
Timepoint [5] 350417 0
30 minutely for 2 hours from initiation of fluid bolus
Secondary outcome [6] 350418 0
Urine output measured hourly via indwelling urinary catheter bag
Timepoint [6] 350418 0
30 minutely for 2 hours from initiation of fluid bolus
Secondary outcome [7] 350419 0
Vasoactive agent requirement as recorded in standard ICU observation chart, the dose per hour of vasoactive agent required to maintain a target mean arterial pressure will be recorded.
Timepoint [7] 350419 0
30 minutely for 2 hours from initiation of fluid bolus
Secondary outcome [8] 350420 0
Blood lactate levels
Timepoint [8] 350420 0
30 minutely for 2 hours from initiation of fluid bolus

Efficacy
Statistical methods / analysis
Outcomes will be compared after log transformation where appropriate. Comparisons will be made using t-test and analysis of variance for repeated measures or Wilcoxon rank-signed test and Kruskal-Wallis according to the underlying distribution for continuous data and Chi-square for categorical data. Analysis will be an on intention-to-treat basis.
