Brief summary
The purpose of this study is to evaluate the value of the new technique of non-invasive measurement of Hb in children undergoing a surgical procedure.
Detailed description
Several surgical procedures require haemoglobin monitoring due to possible blood loss and the need of blood transfusion. The standard for monitoring hemoglobin (Hb) is the measurement of blood samples. The novel technique of non-invasive continuous measurement of Hb using Pulse CO-Oximetry may allow measuring Hb without obtaining blood samples. This new technique has not been tested yet in children undergoing anesthesia for elective surgical procedures. In this study the investigators compare the non-invasive Hb measurement with Masimo® technology (SpHb) with the standard Hb measurement using ABL-800 Flex (BGA) and Siemens Advia (labHb, reference method) before the children undergo the surgical procedure.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| correlation between SpHb(®) and the Hb measured by the ABL800Flex and the Siemens Advia | one day |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| influence of inhalation anesthetics | one day | The blood samples are taken from the needle infusion set the child gets for anesthesia. Some children will need an inhalational induction of anesthesia before they can get the needle and the sensor for the SpHb (®) monitoring. So an influence of the application of inhalation anesthetics on the accuracy of the SpHb (®) will be tested. |
