Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients undergoing elective recumbent and laparoscopic surgeries with minimal expected blood loss.

Probably not a fit

Patients experiencing significant blood loss over 250 ml or those requiring hemodynamic support with noradrenaline will not benefit from this study.

What this trial studies

This study investigates the impact of intraoperative fluid therapy on microcirculation during elective surgeries with minimal blood loss. It aims to optimize fluid infusion rates to enhance oxygen supply to tissues while minimizing hemodilution caused by endothelial glycocalyx damage. The research will analyze flow parameters in microcirculation based on different fluid infusion rates, providing insights into the optimal management of fluid therapy in surgical settings.

Why it matters

Potential benefit: If successful, this study could lead to improved fluid management strategies during surgery, enhancing patient outcomes and recovery.

How similar studies have gone: While the approach of optimizing fluid therapy is established, the specific focus on microcirculation parameters related to infusion rates is relatively novel and has not been extensively tested.
