Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will compare two priming solutions for extracorporeal circulation, one based on Dextran 40, one based on crystalloid and mannitol. Primary endpoint is oncotic pressure during cardiopulmonary bypass. Secondary endpoints included fluid balance and organ functions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, single center, double-blinded, randomized controlled clinical trial. Eighty patients are randomized 1:1 to either cardiopulmonary bypass with the dextran-based solution or standard priming with Ringer-Acetate and Mannitol.

Primary endpoint will be oncotic pressure during cardio pulmonary bypass. Secondary endpoints include perioperative fluid balance, coagulation, platelet function, postoperative bleeding volume, transfusion requirements, renal function, liver function, pulmonary function, inflammatory activation and markers for brain and heart injury.

Blood samples for oncotic pressure measurements will be collected from an arterial line before and during surgery. Organ function will be assessed before surgery and 2 hours cardio pulmonary bypass.

Study Groups

PrimECC

1250 ml of a priming solution based on the colloid Dextran 40 to use for extracorporeal circulation.

Group Type ACTIVE_COMPARATOR

A colloid Dextran 40 solution for extracorporeal circulation

Intervention Type DEVICE

The oncotic pressure of the PrimECC solution is higher than that of a crystalloid Ringer-acetate/mannitol solution. It should maintain the plasma oncotic pressure during and after cardiopulmonary bypass (CPB). Subsequently, the leakage of fluids from the systemic circulation to the interstitial compartment during CPB can be reduced, and a higher plasma volume and a better fluid balance can be achieved.

Ringer-Acetate/Mannitol

1250 ml of a priming solution based on the crystalloid Ringer-Acetate (1000ml) and Mannitol (250ml).

Group Type ACTIVE_COMPARATOR

Ringer-Acetate and Mannitol

Intervention Type DEVICE

Currently clinic standard for priming the CPB circuit.
