Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older who are hospitalized in intensive care and require volume expansion due to shock.

Probably not a fit

Patients who are pregnant or those who refuse participation will not benefit from this study.

What this trial studies

This observational study investigates the haemodynamic effects of administering a standard fluid bolus to patients experiencing shock. It aims to determine the effectiveness of volume expansion through intravenous fluid administration and to identify how much of the fluid administered is actually effective in increasing cardiac output. The study will involve patients aged 18 and older who are hospitalized in intensive care and already have haemodynamic monitoring in place. By analyzing the data collected, the study seeks to provide insights into the optimal management of fluid resuscitation in shock.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment protocols for patients in shock, enhancing their recovery and outcomes.

How similar studies have gone: While the approach of analyzing fluid bolus effects is common, the specific focus on quantifying ineffective volume in a large population is less explored, making this study somewhat novel.
