The evaluation of Perfusion of free flaps in patients with moderate anaemia and possible reduction of the transfusion threshold.
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.
patients scheduled for defect reconstruction with free flaps and a preoperative hematocrit of 28 % or below
Exclusion criteria:
no blood transfusions will be given until hct falls under 25%
patients in group 2 will receive transfusions as is currently standard protocol outside the study
Number of Blood transfusions peri- and postoperative
Time frame: 10 days
