The concept of Patient Blood Management requires preoperative diagnostic of anemia. To avoid the harmful procedure of venous puncture for drawing a blood sample, noninvasive measurement of hemoglobin has been developed. However noninvasive measurement of hemoglobin has yet been not accurate enough to replace invasive hemoglobin measurement. This study investigates if a noninvasive measurement tool can serve as a screening tool to find out for which patients invasive measurement of hemoglobin is necessary.

Primary | Validation of a postulated noninvasively measured haemoglobin value as a cut-off value for the decision wether invasively measuring of haemoglobin concentration for preoperative patient blood management is necessary. | Previous studies show that noninvasively measured haemoglobin is not accurate enough to determine exactly the haemoglobin value for preoperative diagnosis of anaemia. We postulate that noninvasive haemoglobin measurement can be used as a screening tool to decide wether invasive measurement of haemoglobin is necessary. We calculated a cut-off value 1 by analysing previous studies. Noninvasive haemoglobin measurements that are above the cut-off-value are postulated to show that the patient is not anaemic with a sensitivity of 99%. | five to ten minutes | |
Secondary | Validation of postulated non invasively measured haemoglobin value as a cut off-value 2 | We calculated a cut-off value 2 by analysing previous studies. Noninvasive haemoglobin measurements that are below the cut-off-value 2 are postulated to show that the patient is anaemic with a speciality of 99%. | five to ten minutes | |
Secondary | Agreement between invasive and noninvasive measurement in adults and children | Noninvasive haemoglobin measurement values are compared with invasive haemoglobin measurement values | five to ten minutes |
