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
Intravenous administration of Hartmann´s solution in dose of 5 ml per kg of patient´s body weight to test patient´s hemodynamic response in different rate (fluid challenge) - either fast (5-10minutes - Arm 1/Intervention) or slow (25-30 minutes - Arm 2/Control). The fluid challenge will be performed by the treating physician (anesthesiologist or intensive care physician) during anesthesia (within 30 minutes after induction) or at the intensive care unit (within 48 hours of sepsis onset/ ICU admission).
Intervention code [1] 299677 0
Treatment: Drugs
Intervention code [2] 300266 0
Early detection / Screening
Comparator / control treatment
The slow administration of of 5ml/kg patient´s body weight (fluid challenge) of Hartmann´s solution at rate 25-30 minutes (Arm 2/Control) serves as active dose comparison control. The way of administration is the same as in the Intervention Arm 1 - the fluid challenge will be performed by the treating physician (anesthesiologist or intensive care physician) during anesthesia (within 30 minutes after induction) or at the intensive care unit (within 48 hours of sepsis onset/ ICU admission).
Control group
Active

Outcomes
Primary outcome [1] 304035 0
To assess the difference in rate of fluid challenges deemed "positive" after fast (5-10 minutes) and slow (25-30 minutes) fluid challenge. The fluid challenge may be deemed "positive" based on the hemodynamic response (at least one condition met): either increase in mean arterial pressure more than 20% (after vs. before fluid challenge) or drop in plethysmography variability index of more than 5% (before vs. after fluid challenge) or increase in stroke volume more than 15% (before vs. after fluid challenge).
Timepoint [1] 304035 0
Immediately before (within 5 minutes), immediately after (within 5 minutes) and 60 minutes after the administration.
Secondary outcome [1] 340775 0
To assess the difference in microcirculatory response (perfused boundary region) after fast (5-10 minutes) and slow (25-30 minutes) fluid challenge assessed using intravital microscopy in the sublingual region and dedicated analytical software GlycoCheck.
Timepoint [1] 340775 0
Before (within 5 minutes), immediately after (within 5 minutes) and 60 minutes after the administration.
Secondary outcome [2] 342947 0
To assess the difference in microcirculatory response (capillary density) after fast (5-10 minutes) and slow (25-30 minutes) fluid challenge assessed using intravital microscopy in the sublingual region and dedicated analytical software GlycoCheck.
Timepoint [2] 342947 0
Before (within 5 minutes), immediately after (within 5 minutes) and 60 minutes after the administration.
