Brief summary
Pulse CO-Oximetry (Masimo Corp, Irvine, CA, USA) is a method that allows non-invasive continuous hemoglobin (Hb) measurement. This technology measures continuous Hb with a multi-wavelength spectrophotometric fingertip sensor. Aim of investigators in this study is to make continuous Hb measurement with Pulse CO-Oximetry method in living liver donors, to compare these measurements with the laboratory results routinely taken during the operation, to determine the level of correlation for this patient group.
Detailed description
Continuous Hb measurement with Pulse CO-Oximetry (SpHb) can be usefull for living liver donor and improve the quality of intraoperative care. This technology measures continuous Hb with a multi-wavelength spectrophotometric fingertip sensor. The perfusion index (PI) is the ratio of the pulsatile blood flow to the nonpulsatile or static blood in peripheral tissue. Perfusion Index thus represents a noninvasive measure of peripheral perfusion that can be continuously and noninvasively obtained from a pulse oximeter. Changes in PI can also occur as a result of local vasoconstriction (decrease in PI) or vasodilatation (increase in PI) in the skin at the monitoring site. These changes occur with changes in the volumeof oxygenated bloodflow in the skin microvasculature. PI values can change due to surgical process and may affect SpHb measurement. Aim of investigators in this study is to make continuous Hb measurement with Pulse CO-Oximetry method in living liver donors before and after surgery incision, to compare these measurements with the laboratory results routinely taken during the operation, to determine the level of correlation for this patient group.
