Brief Summary

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

The evaluation of Perfusion of free flaps in patients with moderate anaemia and possible reduction of the transfusion threshold.

* Trial with surgical intervention

Detailed Description

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

In study group 1 patients will be kept at a hematocrit level below 28% and only receive transfusions if symptomatic or the fall below 25%. Patients in group 2 will receive transfusions to reach a hematocrit always above 30%.

Tissue perfusion in free flaps will be measured with indocyanine green fluorescence angiography, confocal microscopy and oxygen partial pressure measurement probes.
