Randomized Study on the Effects of Moderate Anaemia in Free Microvascular Tissue Transfer
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.
Observational Model: Cohort, Time Perspective: Prospective
