Accuracy of Non-invasive Hemoglobin Monitoring for Different Fluids
Časové okno: 420 min
|
Pulse-oximeter based measurements compared with invasive hemoglobin measurements. All paired in the study. Accuracy depending on which infusion is selected (Ringer's, Hydroxyethyl starch or a combination of both). |
420 min

Accuracy of Noninvasive Haemoglobin Measurement by Pulse Oximetry, for Different Fluids (Start to End of Infusion)
Časové okno: 30 min
|
Difference between true hemoglobin B-Hb and measured hemoglobin with pulseoximeter (SpHb)at the end of an infusion in relation to the initial measured values SpHb and B-Hb at the start of the infusion. Relative difference (%) = (SpHb - Hb)/((Hb+SpHb)/2) x 100 |

Variation of Coagulation Factors and Plasma Proteins During and After Infusion of Crystalloid and Colloid Solutions.
Časové okno: 420 minutes
|
The investigators will measure a few markers of coagulation (fibrinogen, thrombocytes, D-Dimer, PK-INR, aPTT, and coagulation factor VII) as well as Cystatin C, serum albumine and hemoglobin and how the concentration of these vary with the different dilutions of blood during and after infusion of a colloid and/or a crystalloid solution.
