Optimizing fluid management during brain surgery

A Comparison of Perioperative Fluid Management Using Invasive Haemodynamical Measurement of Fluid Responsiveness (Aisys GE) and Non-invasive Measurement of Haemodynamics (ClearSight System, Edwards) During Brain Surgery

NA · University Hospital Hradec Kralove · NCT04114799

This study is testing whether using a new noninvasive monitoring system can help manage fluids better during brain surgery compared to traditional invasive methods, to see if it leads to safer outcomes for patients.

What this trial studies

This study aims to enhance fluid management during brain surgery by comparing two methods of hemodynamic monitoring: invasive measurements using pulse pressure variation (PPV) and systolic pressure variation (SPV) versus noninvasive measurements using the ClearSight system. The goal is to reduce perioperative risks and improve patient outcomes by ensuring adequate fluid management based on the most effective monitoring technique. Participants will be assigned to either the invasive or noninvasive group to evaluate the effectiveness of each approach in optimizing fluid responsiveness.

Who should consider this trial

Good fit: Ideal candidates include patients with a Glasgow Coma Scale score of 15, ASA Physical Status Classification I-III, scheduled for brain tumor surgery lasting up to 5 hours.

Not a fit: Patients with severe heart failure (NYHA III, IV), those with a high BMI, or those requiring awake operations may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved outcomes and reduced complications for patients undergoing brain surgery.

How similar studies have performed: Other studies have shown promise in optimizing fluid management using similar hemodynamic monitoring techniques, suggesting potential for success in this approach.
